SAN RAFAEL CITY COUNCIL AGENDA REPORT
Department: Public Works
Prepared by: Bill Guerin,
Director of Public Works
City Manager Approval: ________
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 2
BACKGROUND: The California Department of Transportation (Caltrans) routinely inspects
bridges statewide to ensure the public’s safety. Through this process, the Southern Heights
Bridge was identified as needing to be reconstructed to meet current design, structural, and
safety standards. The cost associated with design and construction of this bridge replacement
project is 100 percent funded through the State’s Highway Bridge Program (HBP). No local
match of City funds is required for the bridge; however, construction elements not necessitated
by bridge construction, such as resurfacing a small portion of Meyer Road adjacent to the
project site, will be at the City’s expense. In June 2016, the City retained Mark Thomas and
Company, Inc. to begin preliminary design and public outreach. Since that time, the City has
diligently worked with the community to understand their needs and perform bridge design. With
City Council and community input, a preferred design alternative was selected in February
2017, and the City has proceeded with the design and right of way, most recently increasing the
agreement with Mark Thomas and Company in early December 2017.
On December 28, 2017, Caltrans inspectors made a regularly scheduled site visit to the bridge
and determined that the bridge should be immediately closed to all vehicle and pedestrian traffic
due to safety concerns. Since the December 2017 closure, staff and the design team have
performed the following major tasks:
1.Environmental Clearance – the team coordinated closely with Caltrans to expedite the
environmental review process, which resulted in environmental clearance at the federal
level (i.e., National Environmental Policy Act (NEPA) clearance) being procured on
February 9, 2018. With federal environmental clearance complete, the design team has
worked to complete appropriate California Environmental Quality Act (CEQA) documents
for the State of California as described in detail below in the Analysis section.
2.Utility Coordination – the team has coordinated with private utility companies. The
existing bridge has both water and gas lines mounted to it. In April 2018, the Marin
Municipal Water District (MMWD) installed a new water line on each side of the bridge
and abandoned in place the old water line attached to the bridge. Staff continue to work
with Pacific Gas and Electric (PG&E) for installation of a new gas line on each approach
to the bridge; PG&E will also abandon their gas line currently attached to the bridge. We
anticipate PG&E will perform their gas line work during Spring/Summer 2019. The
design team is also coordinating with PG&E, AT&T, and Comcast regarding the
relocation of one wood utility pole impacted by the new bridge design. Each of these
utilities requires months of coordination to address.
3.Temporary Construction Easements – the team has worked hand in hand with residents
and property owners to understand their concerns as well as discuss the City’s desire to
rent portions of private property to facilitate construction of the new bridge. While many
residents will be impacted by construction, the team has spent considerable effort
coordinating with seven property owners whose parcels touch the project site.
Temporary Construction Easements (TCEs) allow the City’s contractor legal access to
private property and are necessary as the City’s public right of way is too narrow for
constructing the new bridge. To date, five of the seven property owners involved have
agreed to the terms and conditions proposed by the City. Once the remaining property
owners and City come to an agreement, staff will bring the seven proposed contracts
before the City Council for approval. We anticipate this happening in spring 2019.
4.Construction Documents – the design team has advanced the construction plans and
specifications to approximately the 80-percent design level. An intermediate, draft plan
set was produced to the 65-percent design level at which time City staff held two
meetings in August 2018 with the seven property owners for which TCE’s are required.
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 3
The construction plans were then revised to incorporate details requested by property
owners and City staff.
ANALYSIS: As the Southern Heights Bridge Replacement Project is progressing toward
construction, staff recommends the City Council approve and/or adopt the resolutions, as set
forth below.
1.Resolution re Adoption of the Mitigated Negative Declaration
Following environmental clearance at the federal level in February 2018, the design
team developed environmental documentation for the State of California in compliance
with the California Environmental Quality Act (CEQA). An Initial Study was prepared to
determine the potential environmental impacts, which found that the proposed project
would potentially affect biological resources, cultural (archaeological) resources,
hazardous materials, air quality, and noise. The project impacts would be mitigated to a
less-than-significant level through implementation of recommended mitigation measures
or through compliance with certain applicable agency requirements, as set forth in the
Mitigation Monitoring and Reporting Program (“MMRP”).
A Notice of Public Hearing and Intent to Adopt the Initial Study/Mitigated Negative
Declaration was published in the Marin IJ on June 16, 2018 (see Attachment 2). As
required by CEQA Guidelines Section 15073, a minimum 30-day public review period
was provided for the Initial Study/Mitigated Negative Declaration.
The Initial Study/Mitigated Negative Declaration, including the MMRP, is on the City’s
website, and can be accessed for review at: https://www.cityofsanrafael.org/southern-
heights-bridge-replacement/ (Attachment 3). The formal public review period closed on
July 16, 2018 with the City receiving one comment indicating that the City complied with
State Clearinghouse review requirements (see Attachment 4).
Following the close of the public comment period, the City received comments from one
Southern Heights resident, which discussed street lighting, geological conditions,
erosion control methods during construction, storm drain improvements, and traffic
concerns. While the comments were received after the public comment period closed,
City staff reviewed and prepared responses to the comments (see Attachment 5).
The Public Hearing for the Initial Study/Mitigated Negative Declaration, originally
scheduled for August 20, 2018, was postponed while the design team continued to fine
tune the design. Changes in the design have occurred since the completion of the Initial
Study/Mitigated Negative Declaration but are considered minor and do not materially
affect the findings of the original environmental document nor do they warrant additional
public circulation. Staff published a new Notice of Public Hearing in the Marin IJ on
Saturday, January 5, 2019 and mailed public notices to residents living within 1,000 feet
of the bridge.
After extensive study, staff and the design team recommend the removal of no more
than 15 trees as a result of minor roadway widening and/or bridge construction. Included
in this is the removal of three very large, and old, eucalyptus trees at or near the
intersection of Southern Heights Boulevard and Meyer Road – the fourth large
eucalyptus tree fell during a storm event on January 8, 2019 and resulted in a small
grass fire after the high voltage lines were struck. Residents have requested these trees
be removed whether directly impacted by the bridge construction or not due to fire
danger concerns and the trees shedding large amounts of foliage onto the high voltage
electrical lines below.
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 4
The recommended resolution would adopt the Mitigated Negative Declaration and
approve the Mitigation Monitoring and Reporting Program in accordance with CEQA
Guidelines and clear this project for construction from the environmental clearance
standpoint. No permits are required from environmental regulatory agencies as part of
this bridge project.
2.Resolution re Agreement with Mark Thomas and Company for Engineering Design Services
In December 2017, the City Council authorized the First Amendment to incorporate final
design and right of way services into the agreement. Over the past year, revisions to the
design have become necessary as a result of coordination with private property owners.
While the bridge design itself remains largely unchanged from the original conceptual
design, unanticipated roadway widening on Southern Heights Boulevard from the bridge
to the intersection with Meyer Road is necessary to allow the residents at 116 Southern
Heights Boulevard unimpeded access to their home during the majority of construction.
This minor roadway widening, coupled with landscaping restoration, additional retaining
walls, and low-level bridge deck lighting, all at the request of the community, require
additional design effort.
The recommended resolution authorizes the City Manager to execute a Second
Amendment to the existing professional services agreement with Mark Thomas and
Company to include the additional design and right of way services, in an additional
amount not to exceed $132,777, bringing the total contract amount to $717,844. Staff
has reviewed the proposal and found it to be complete and within industry standards.
3.Resolution re Adoption of the Plans and Specifications
With City Council approval of the recommended resolutions set forth above, the City is
well positioned to advance the Southern Heights Bridge project toward construction.
While the construction plans and specifications require additional refinement and review
prior to advertising, it is recommended that the plans and specifications be approved and
adopted at this time, and that the City Clerk be authorized to call for bids following
receipt of Caltrans authorization to proceed with construction.
FISCAL IMPACT: All eligible expenses directly related to the bridge replacement are
reimbursed by Caltrans. While the project requires internal staff time to manage the project, no
direct financial cost to the City is associated with the replacement of the bridge with the
exception of minor utility work, which may be cost shared by the City pursuant to applicable
Franchise Agreements. Staff recommends Council authorize a Second Amendment to the
professional services agreement with Mark Thomas and Company in the amount of $132,777.
No immediate fiscal impact is associated with the approval and adoption of the Mitigated
Negative Declaration or adoption of the project plans and specifications. The project budget
and estimated expenses for design and right of way services are outlined in the tables below:

OPTIONS:
1.Adopt all three resolutions as presented.
2.The City Council may decline to approve one or more resolutions. Depending on the
type of resolution, the bridge project may be unable to move forward. If the City does not
advance the project into construction, we will be required to pay back the State of
California for all funds utilized to date for design and environmental clearance.
3.The City Council may defer action and request staff to provide further information or
modifications at a future Council meeting.
RECOMMENDED ACTION:
1.Open the public hearing, accept public comment on the Initial Study/Mitigated Negative
Declaration and Mitigation Monitoring and Reporting Program, and adopt a resolution
adopting the Mitigated Negative Declaration and Mitigation Monitoring and Reporting
Program for the Southern Heights Bridge Replacement Project.
2.Adopt a resolution authorizing the City Manager to execute a second amendment to the
professional services agreement with Mark Thomas and Company for additional final
design and right of way services in an amount not to exceed $132,777, increasing the
total not to exceed amount under the agreement to $717,844.

1.0 INTRODUCTION
The City of San Rafael Public Works Department (City of San Rafael), the lead agency, proposes to
replace the existing Southern Heights Bridge (No. 27C0148) on Southern Heights Boulevard (herein
referred to as the Project) with a new bridge. The proposed Project would replace the existing
narrow 162-foot long, multi-span, timber structure, constructed in 1930, reconstructed in 1958, and
rehabilitated in 1981. The California Department of Transportation (Caltrans) performed a routine
bridge inspection on the existing bridge (Bridge No. 27C0148) on December 28, 2017. During the
inspection, it was discovered that the bridge exhibited severe deterioration and loss of connection
with the superstructure. Caltrans immediately closed the bridge and notified the City of San Rafael.
The bridge is to remain closed until the proposed Project is implemented or intermediate repairs are
made.
1.1 ENVIRONMENTAL REVIEW
The proposed Project constitutes a “Project” in accordance with CEQA. Prior to approving the
proposed Project, the City of San Rafael must provide environmental review in accordance with
CEQA to assess the potential impacts of the proposed Project, including mitigation where necessary.
The City of San Rafael has prepared this Initial Study to provide agencies and the public with
information about the potential impacts of the proposed Project on the local and regional
environment. This document has been prepared in compliance with the California Environmental
Quality Act (CEQA) of 1970 as amended, and the State CEQA Guidelines, California Administrative
Code, Title 14, Division 6, Chapter 3 (CEQA Guidelines). In anticipation of determining that all
potentially significant impacts resulting from the proposed Project can be mitigated to less than
significant levels, a Mitigated Negative Declaration is being considered to provide environmental
clearance for the proposed Project.
1.2 CLARIFICATIONS AND CORRECTIONS
During the public review period, one comment letter was received, from the State of California
Governor’s Office of Planning and Research State Clearinghouse and Planning Unit. The comment
letter did not identify the need for clarification or revisions to the IS/MND text. On the Cover and
Title Pages of this document the word “Draft” has been deleted and the word “Final” has been
added and the State Clearinghouse number has been added. Sections 1.2 “Clarifications and
Corrections”, 1.3 “Public Comments”, 1.4 “Response To Comment Format”, and 1.5 “Additional
Documentation” have been added to this Final IS/MND and provides discussion of steps that have
been taken since the public circulation of the Draft IS/MND. Section 1.2 “Summary Information” of
the Draft IS/MND has been renumbered and is included in this Final IS/MND as Section 1.6. Section
5.0 “Response to Comments” has been added to this Final IS/MND and provides response to
comments that were received during the public review period of the Draft IS/MND occurring from
June 15, 2018 to July 16, 2018. Section 6.0 “Mitigation and Monitoring Program” has also been

4. Project Location:
The Project site is a bridge located in eastern Marin County just south of central San Rafael. The
Southern Heights Boulevard Bridge is located just north of the intersection of Meyer Road and
Southern Heights Boulevard in the Southern Heights neighborhood of San Rafael. The Project
site is approximately 0.34 acres in size. Figure 1: Regional Location and Figure 2: Project Vicinity
show the location of the Project site on a regional and local scale, respectively.
5. Project Sponsor’s Name and Address: City of San Rafael Public Works Department
111 Morphew Street, San Rafael, California 94901.
6. General Plan Designation: The City of San Rafael General Plan 2020 Land Use Map identifies the
parcels surrounding the Project site as Hillside Residential (0.5-2 units/acre), Residential – Low
Density (2-6.5 unites/acre), and Open Space.
7. Zoning: The parcels surrounding the Project site are designated as Single Family Residential
(R1a-H, R7.5, R20) and Parks/Open Space (P/OS).
8. Description of Project: Southern Heights Boulevard is a narrow one-lane roadway that provides
local access to residential properties throughout the neighborhood. The existing bridge was
constructed circa 1930, reconstructed in 1958, and rehabilitated in 1981. The hillside crossing
consists of a 162-foot long, multi-span, timber structure.
The California Department of Transportation (Caltrans) performed a routine bridge inspection
on the existing bridge (Bridge No. 27C0148) on December 28, 2017. During the inspection, it was
discovered that the bridge exhibited severe deterioration and loss of connection with the
superstructure. Caltrans immediately closed the bridge and notified the City of San Rafael. The
bridge is to remain closed until the proposed Project is implemented or intermediate repairs are
made.
The proposed project will replace the existing bridge with a new structure accommodating one
12-foot wide lane and bridge railings, resulting in an approximate bridge width of 15 feet. The
new bridge will be a three-span, reinforced concrete slab structure, approximately 127 feet
long. The roadway alignment and grade will remain unchanged. The existing right-of-way width
is 20 feet.

No new right-of-way will be required for the new bridge or retaining walls. Temporary
construction easements (TCE) are anticipated on the east and west sides of the bridge to
provide construction access. Utilities, including overhead power and communication and
underground water and natural gas, will need to be relocated with the project. It is not yet clear
if the overhead utility relocations can be accommodated within the existing right-of-way or if
utility easements will be needed for the utility poles and wires. The water and gas lines will be
relocated onto the new bridge.
Construction of the bridge will involve excavation for and construction of concrete abutments
and piers. The structure will be supported on cast-in-drilled-hole piles. There is no waterway
beneath the bridge but a corrugated metal storm drain pipe will need to be temporarily
relocated away from the structure during the construction. Construction of the roadway
approaches will involve the removal of existing pavement, retaining walls, and fences, and the
placement of fill material, aggregate base, hot mix asphalt pavement, concrete retaining walls,
and new guardrails. Tree removal and removal of other vegetation along the slopes adjacent to
the bridge will be necessary for the project.
Construction may begin as early as winter 2019 and will have a duration of approximately
twelve months.
9. Surrounding Land Uses and Setting: The proposed Project is located in the southwestern
portion of the City of San Rafael, along Southern Heights Boulevard. According to the City of San
Rafael General Plan 2020 Land Use Map, surrounding land uses include Hillside Residential (0.5-
2 units/acre), Residential – Low Density (2-6.5 unites/acre), and Open Space.
10. Other Public Agencies Whose Approval is Required (i.e., permits, financial approval, or
participation agreements):
• Caltrans: NEPA Clearance – Categorical Exclusion
• Regional Water Quality Control Board National Pollutant Discharge Elimination System
Stormwater General Construction Permit
11. Have California Native American tribes traditionally and culturally affiliated with the project
area requested consultation pursuant to Public Resource Code section 21080.3.1? If so, has
consultation begun?
The Federated Indians of Graton Rancheria (FIGR) have requested consultation pursuant to
Public Resource Code section 21080.3.1. Consultation with FIGR was initiated and is considered
complete.

Impact
Would the project:
a. Have a substantial adverse effect on a scenic vista?
b. Substantially damage scenic resources, including, but not
limited to, trees, rock outcroppings, and historic buildings
within a state scenic highway
c. Substantially degrade the existing visual character or quality
of the site and its surroundings?
d. Create a new source of substantial light or glare which
would adversely affect day or nighttime views in the area?
3.1.1 Environmental Setting
The major features that give San Rafael its visual character are the hills and valleys, the San
Francisco Bay (Bay), creeks, the San Rafael Canal, the highways and other transportation corridors,
neighborhoods, and the Downtown. The City's historic structures also add to the uniqueness and
identity of San Rafael. These include the Mission San Rafael Arcángel and St. Raphael's Church,
historic homes, buildings in the Downtown constructed from the late 1800s through the 1920s, the
Rafael Film Center and the Marin Civic Center. New development and other physical alterations are
required to respect the existing character and scale of the City.
The area surrounding the existing Southern Heights Boulevard Bridge is hilly and residential, with
winding streets and homes set against the hillside at varying angles and elevations. Area residents
value the aesthetics of the existing bridge; in public meetings, residents have praised the “quaint”
aesthetic of the existing bridge. Likewise, participants expressed an interest in retaining design
features such as the existing cantilevers, white horizontal boards, and top railing in order for the
new bridge to echo the white-washed wood look of the existing bridge. Residents also requested
retention of as much as possible of the tree canopy, as it contributes to the look of the bridge and
the neighborhood.
The roads in the Project area are narrow and winding, providing some scenic vistas which are
interrupted by homes and trees. Southern Heights Boulevard within the Project site is on the west
side of the hilltop, and extends in a north-south alignment. From the northern end of the bridge
traveling south, there are clear views to Mount Tamalpais, though the views are interrupted and
disappear due to tree cover in the center and southern end of the bridge. Approximately 91 percent
of the 0.34-acre project footprint is covered by the tree canopy (0.31-acre). The trees in the area are
largely California Bay Laurel and Coastal Live Oak, with a mix of other species. Both California Bay
Laurel and Coastal Live Oak are evergreen species, so views to Mount Tamalpais from the center and
southern end of the bridge would remain interrupted throughout the year.

In the City of San Rafael’s General Plan Community Design (CD) Element, two policies with respect to
visual resources are relevant to the proposed Project. These are:
• CD-5: Views. Respect and enhance to the greatest extent possible, views of the Bay and its
islands, Bay wetlands, St. Raphael’s church bell tower, Canal front, marinas, Mt. Tamalpais,
Marin Civic Center and hills and ridgelines from public streets, parks and publicly accessible
pathways.
• CD-6: Hillsides and Bay. Protect the visual identity of the hillsides and Bay by controlling
development within hillside areas, providing setbacks from the Bay, and providing public access
along the Bay edge.
Thus, views along Southern Heights Boulevard in the Project footprint as well as the visual setting of
the Project vicinity are protected under both CD-5 and CD-6.
No designated state scenic highways or locally designated scenic roadways are within or adjacent to
the Project site (Caltrans 2017; City of San Rafael 2004).
3.1.2 Impact Analysis
a. Would the project have a substantial effect on a scenic vista?
LESS THAN SIGNIFICANT IMPACT. Scenic vistas from the Project site include views of Mt. Tamalpais
to the south and views of hills and ridgelines to the north. During construction, equipment may
block some views from Southern Heights Boulevard; however, this impact would be temporary.
Implementation of the proposed Project would not affect these vistas as views from the northern
end of the bridge to Mount Tamalpais and from the southern end of the bridge to the hills and
ridgelines to the north would not be blocked by the new bridge. Therefore, Project impacts on
scenic vistas would be less than significant.
b. Would the project substantially damage scenic resources, including, but not limited to, trees,
rock outcroppings, and historic buildings within a state scenic highway?
NO IMPACT. The Project site is located within the City of San Rafael. No designated state scenic
highways or locally designated scenic roadways are within or adjacent to the Project site. Therefore,
the proposed Project would not substantially damage scenic resources within a state scenic
highway.
c. Would the project substantially degrade the existing visual character or quality of the site and its
surroundings?
LESS THAN SIGNIFICANT IMPACT. The Project would involve the construction of a new bridge along
Southern Heights Boulevard. Most visual changes to the Project footprint would be temporary (over
the construction period) and are considered to be minor, including the presence of construction
equipment. Once the proposed Project is operational, residents adjacent to the Southern Heights
Boulevard Bridge, pedestrians, and motorists travelling through the area, and other visitors may

notice a visual change compared to existing conditions; however, these changes would be minor and
would not degrade the visual quality of the Project area. The new bridge would be designed with
modern engineering, but would adhere to the design preferences of the City and residents to the
extent feasible and would be consistent with the guidance in the City of San Rafael General Plan
2020 and the architectural character of the area.
Once construction is complete, the proposed Project would not create any new visual impacts
within or adjacent to the Project area that have not been previously introduced by the existing
roadway. The proposed Project would not significantly increase the bridge footprint on the
surrounding landscape. In addition, the Project would not change the use, function, or scenic values
associated with adjacent properties. Several trees along the new bridge (west of the bridge) would
be removed due to construction of the new bridge. The ten trees slated for removal are (1) a Pacific
madrone (Arbutus menziesii), (2) an oak (Quercus sp.), (3) seven California Bay Laurels (Umbellularia
californica), and (4) a single-tree, multi-trunk California Bay Laurel (Umbellularia californica).
Approximately 36.1 percent, or 0.11 acres, of the 0.31-acre tree canopy within the 0.34-acre project
footprint would be removed. The average diameter-at-breast-height of the trees proposed for
removal is 26.7 inches. The ten trees to be removed represent a small percentage of the local
canopy. Viewers from the road and off the road alike will likely notice a nominal change in the view
scape of the Project area. The loss of ten trees would result in a less-than-adverse effect on visual
resources. Therefore, the Project will not substantially degrade existing visual character or quality of
the site and its surroundings. Mitigation Measures AES-1 and AES-2 are recommended to further
reduce this less-than-significant impact.
Mitigation Measure AES-1: Following completion of the new bridge, all fill slopes,
temporary impact and/or otherwise disturbed areas shall be restored to
preconstruction contours (if necessary) and revegetated with the native seed mix
specified in Table 1 below.

aesthetic parameters requested by residents into project design in order to
minimize both temporary and permanent visual impacts.
d. Would the project create a new source of substantial light or glare which would adversely affect
day or nighttime views in the area?
LESS THAN SIGNIFICANT IMPACT. One street lamp currently exists on a utility pole on the south side
of the bridge. The proposed Project would relocate this existing utility pole and lighting would either
be reinstalled on the relocated pole or provided along the bridge railing. Lighting installed as part of
the Project would be low-level lighting that would not diminish nighttime views. Changes from
existing lighting conditions are anticipated to be minor. Materials utilized on the bridge structure
would not produce glare. Therefore, the Project would not create new sources of substantial light or
glare which would adversely affect day or nighttime views in the area and impacts would be less
than significant.

3.2 AGRICULTURE AND FORESTRY RESOURCES
In determining whether impacts to agricultural resources are significant environmental effects, lead
agencies may refer to the California Agricultural Land Evaluation and Site Assessment (LESA) Model
(1997) prepared by the California Dept. of Conservation as an optional model to use in assessing
impacts on agriculture and farmland. In determining whether impacts to forest resources, including
timberland, are significant environmental effects, lead agencies may refer to information compiled
by the California Department of Forestry and Fire Protection regarding the state’s inventory of
forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment
Project; and the forest carbon measurement methodology provided in Forest Protocols adopted by
the California Air Resources Board.

3.2.1 Environmental Setting
The California Department of Conservation Farmland Mapping and Monitoring Program (FMMP)
produces maps and statistical data used for analyzing impacts on California’s agricultural resources
based on soil information documented by the United States (U.S.) Department of Agriculture
Natural Resources Conservation Service (NRCS). Agricultural land is rated by the NRCS according to
soil quality and irrigation status. Lands with soils best suited for agricultural production are
designated as Prime Farmland, Unique Farmland, and Farmland of Statewide Importance and are
collectively known as Important Farmland. The FMMP maps are updated every two years with the
use of a computer mapping system, aerial imagery, public review, and field reconnaissance. FMMPs
statistical and mapping information syncs with modern soil surveys developed by the U.S.
Department of Agriculture. The FMMP designates land into the following categories within Marin

County: Prime Farmland; Farmland of Statewide Importance; Unique Farmland; Farmland of Local
Importance; Farmland of Local Potential; Grazing Land; Urban and Built-Up Land; Other Land; and,
Water. The following provides definitions of each of these designations:
• Prime Farmland – Farmland with the best combination of physical and chemical features able to
sustain long-term agricultural production. Prime Farmland has the soil quality, growing season,
and moisture supply needed to produce sustained high yields. Lands designated as Prime
Farmland must have been used for irrigated agricultural production at some time during the
four years prior to the mapping date;
• Farmland of Statewide Importance – Farmland similar to Prime Farmland but with minor
shortcomings, such as greater slopes or less ability to store soil moisture. Lands with a
“Farmland of Statewide Importance” designation must have been used for irrigated agricultural
production at some time during the four years prior to the mapping date;
• Unique Farmland – Farmland of lesser quality soils used for the production of the State's leading
agricultural crops. This land is usually irrigated, but may include non-irrigated orchards or
vineyards as found in some climatic zones in California. Land must have been cropped at some
time during the four years prior to the mapping date.
• Farmland of Local Importance – Land of importance to the local agricultural economy as
determined by each county’s board of supervisors and a local advisory committee. In Yolo
County, this includes cultivated farmland having soils which meet the criteria for Prime or
Statewide, except that the land is not presently irrigated, and other non-irrigated farmland;
• Farmland of Local Potential – Prime or Statewide soils which are presently not irrigated or
cultivated;
• Grazing Land – Land on which the existing vegetation is suited to the grazing of livestock. This
category was developed in cooperation with the California Cattleman’s Association, University
of California Cooperative Extension, and other groups interested in the extent of grazing
activities;
• Urban and Built-Up Land – Land occupied by structures with a building density of at least 1 unit
to 1.5 acres, or approximately 6 structures to a 10-acre parcel. This land is used for residential,
industrial, commercial, construction, institutional, public administration, railroad and other
transportation yards, cemeteries, airports, golf courses, sanitary landfills, sewage treatment,
water control structures, and other developed purposes;
• Other Land – Land not included in any other mapping category. Common examples include low
density rural developments; brush, timber, wetland, and riparian areas not suitable for livestock
grazing; confined livestock, poultry or aquaculture facilities; strip mines, borrow pits; and water
bodies smaller than forty acres. Vacant and nonagricultural land surrounded on all sides by
urban development and greater than 40 acres is mapped under this designation; and,

• Water – Perennial water bodies with an extent of at least 40 acres.
The proposed Project footprint is 0.34 acres in size and is located in eastern Marin County just south
of central San Rafael. The most recent (2014) FMMP Marin County Important Farmland Map
designates the Project site and surrounding area as Urban and Built-Up Land (DOC 2016a).
According to the DOC’s most recent Marin County Williamson Act Map (2010/2011), no Williamson
Act parcels are located in the vicinity of the Project site (DOC 2016b). Land uses in the vicinity of the
Project site are designated as Hillside Residential, Residential – Low Density, and Open Space (City of
San Rafael 2004). No forest or timberland is located within or adjacent to the proposed Project site.
As no farmland is located on the Project site, LESA Model analysis is not warranted.
3.2.2 Impact Analysis
a. Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance (Farmland) as shown on the maps prepared pursuant to the Farmland Mapping and
Monitoring Program of the California Resources Agency, to non-agricultural use?
NO IMPACT. The proposed Project site does not contain Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance. Therefore, no impacts to Important Farmland would occur.
b. Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract?
NO IMPACT. The proposed Project site is located in an area that is zoned as Single Family Residential
and Parks/Open Space. No Williamson Act parcels are located in the Project vicinity. Therefore, the
Project would not conflict with existing zoning for agricultural use or a Williamson Act contract. No
impacts would occur.
c. Would the project conflict with existing zoning for, or cause rezoning of, forest land (as defined in
Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code
Section 4526), or timberland zoned Timberland Production (as defined by Government Code
Section 51104(g))?
NO IMPACT. The proposed Project site is located in an area that is zoned as Single Family Residential
and Parks/Open Space. No forest land or timberland is located within or adjacent to the Project site.
Therefore, the Project would not conflict with existing zoning for, or cause rezoning of, forest land or
timberland. No impacts would occur.
d. Would the project result in the loss of forest land or conversion of forestland to non-forest use?
NO IMPACT. The proposed Project site does not contain designated forest land. Therefore, no
impacts to forest land would occur.

d. Expose sensitive receptors to substantial pollutant
concentrations?
e. Create objectionable odors affecting a substantial number
of people?
3.3.1 Environmental Setting
The proposed Project is located in the City of San Rafael, and is within the jurisdiction of the Bay
Area Air Quality Management District (BAAQMD), which regulates air quality in the San Francisco
Bay Area. Air quality conditions in the San Francisco Bay Area have improved significantly since the
BAAQMD was created in 1955. Ambient concentrations of air pollutants and the number of days
during which the region exceeds air quality standards have fallen substantially. In Livermore, and the
rest of the air basin, exceedances of air quality standards occur primarily during meteorological
conditions conducive to high pollution levels, such as cold, windless winter nights or hot, sunny
summer afternoons.
Within the BAAQMD, ambient air quality standards for ozone, carbon monoxide (CO), nitrogen
dioxide (NO2), sulfur dioxide (SO2), particulate matter (PM10, PM2.5), and lead (Pb) have been set by
both the State of California and the federal government. The State has also set standards for sulfate
and visibility. The BAAQMD is under State non-attainment status for ozone and particulate matter
standards. The BAAQMD is classified as non-attainment for the federal ozone 8-hour standard and
non-attainment for the federal PM2.5 24-hour standard.
This analysis follows the methods outlined in the BAAQMD CEQA Air Quality Guidelines.1

3.3.2 Impact Analysis
a. Would the project conflict with or obstruct implementation of the applicable air quality plan?
LESS THAN SIGNIFICANT IMPACT. The applicable air quality plan is the BAAQMD’s 2017 Clean Air
Plan, adopted on April 19, 2017. The 2017 Clean Air Plan/Regional Climate Protection Strategy
serves as a roadmap for the BAAQMD to reduce air pollution and protect public health and the
global climate. The 2017 Clean Air Plan also includes measures and programs to reduce emissions of
fine particulates and toxic air contaminants. In addition, the Regional Climate Protection Strategy is
included in the 2017 Clean Air Plan, which identifies potential rules, control measures, and
strategies that the BAAQMD can pursue to reduce greenhouse gases throughout the Bay Area.
Consistency with the 2017 Clean Air Plan is determined by whether or not the proposed Project
would result in significant and unavoidable air quality impacts or hinder implementation of control
measures (e.g., excessive parking or preclude extension of transit lane or bicycle path). As previously
noted, the proposed Project would replace an existing structurally deficient bridge. The proposed
roadway alignment and grade will remain unchanged and would not result in an increase in vehicle
trips or vehicle miles traveled (VMT). Therefore, the proposed Project would not hinder
implementation of the BAAQMD’s initiatives to reduce vehicle trips and vehicle miles traveled.
In addition, as indicated in the analysis that follows, the proposed Project would not result in
significant operational or construction-period emissions, with implementation of Mitigation
Measure AIR-1. Therefore, the proposed Project supports the goals of the Clean Air Plan and would
not conflict with any of the control measures identified in the Clean Air Plan or measures designed
to bring the region into attainment. Additionally, the proposed Project would not substantially
increase the population, vehicle trips, or vehicle miles traveled. The proposed Project would not
hinder the region from attaining the goals outlined in the Clean Air Plan. Therefore, the proposed
Project would not hinder or disrupt implementation of any control measures from the Clean Air
Plan. This impact would be less than significant.
b. Would the project violate any air quality standard or contribute substantially to an existing or
projected air quality violation?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. Both State and federal
governments have established health-based Ambient Air Quality Standards for six criteria pollutants:
CO, O3, NO2, SO2, Pb, and suspended particulate matter (PM). These standards are designed to
protect the health and welfare of the populace with a reasonable margin of safety.
According to the BAAQMD's CEQA Guidelines, to meet air quality standards for operational-related
criteria air pollutant and air precursor impacts, the Project must not:
• Generate average daily construction emissions of reactive organic gases (ROG), nitrogen oxides
(NOx), or PM2.5 greater than 54 pounds per day or PM10 exhaust emissions greater than 82
pounds per day;
• Contribute to CO concentrations exceeding the State ambient air quality standards; or

• Generate operation emissions of ROG, NOx, or PM2.5 of greater than 10 tons per year or 54
pounds per day or PM10 emissions greater than 15 tons per year or 82 pounds per day.
Construction and operation emissions associated with the proposed Project are analyzed below. As
discussed, the proposed Project would not generate significant operation-period emissions and,
with implementation of Mitigation Measure AIR-1, the Project would not generate construction-
period emissions in excess of established standards. Therefore, the Project would not violate any air
quality standards or contribute substantially to an existing or projected air quality violation.
Construction Impacts
During construction, short-term degradation of air quality may occur due to the release of
particulate matter emissions (i.e., fugitive dust) generated by grading, hauling, and other activities.
Emissions from construction equipment are also anticipated and would include CO, NOx, ROG,
directly-emitted particulate matter (PM2.5 and PM10), and toxic air contaminants (TAC) such as diesel
exhaust particulate matter.
Site preparation and Project construction would involve grading, paving, and other activities.
Construction-related effects on air quality from the proposed Project would be greatest during the
site preparation phase due to the disturbance of soils. If not properly controlled, these activities
would temporarily generate particulate emissions. Sources of fugitive dust would include disturbed
soils at the construction site. Unless properly controlled, vehicles leaving the site would deposit dirt
and mud on local streets, which could be an additional source of airborne dust after it dries. PM10
emissions would vary from day to day, depending on the nature and magnitude of construction
activity and local weather conditions. PM10 emissions would depend on soil moisture, silt content of
soil, wind speed, and the amount of operating equipment. Larger dust particles would settle near
the source, while fine particles would be dispersed over greater distances from the construction
site.
Water or other soil stabilizers can be used to control dust, resulting in emission reductions of 50
percent or more. The BAAQMD has established standard measures for reducing fugitive dust emis-
sions (PM10). With the implementation of these Basic Construction Mitigation Measures, fugitive
dust emissions from construction activities would not result in adverse air quality impacts.
If construction activities were to increase traffic congestion in the area, CO and other emissions
from traffic would increase slightly while those vehicles are delayed. These emissions would be
temporary and limited to the immediate area surrounding the construction site.
Construction emissions were estimated for the Project using the Sacramento Metropolitan Air
Quality Management District’s Road Construction Emissions Model, Version 8.1.0 (Roadmod) as
recommended by the BAAQMD for linear construction projects. Construction-related emissions are
presented in Table 2. Detailed calculations are provided in Appendix A.

As shown in Table 2, construction emissions associated with the Project would be less than
significant for ROG and PM2.5 and PM10 exhaust emissions, however NOx emissions would exceed the
BAAQMD threshold resulting in a significant impact. The BAAQMD requires the implementation of
Basic Construction Mitigation Measures to reduce construction dust impacts to a less than
significant level. Implementation of Mitigation Measure AIR-1, which includes the Basic Construction
Measures and an additional measure to require cleaner engines, would reduce construction dust
and NOx emissions to a less-than-significant level.
Mitigation Measure AIR-1: Consistent with the Basic Construction Mitigation
Measures required by the BAAQMD, the following actions shall be incorporated into
construction contracts and specifications for the Project:
• All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded
areas, and unpaved access roads) shall be watered two times per day with
reclaimed water, if available.
• All haul trucks transporting soil, sand, or other loose material off-site shall
be covered.
• All visible mud or dirt tracked-out onto adjacent public roads shall be
removed using wet power vacuum street sweepers at least once per day.
The use of dry power sweeping is prohibited.
• All vehicle speeds on unpaved roads shall be limited to 15 mph.
• All roadways, driveways, and sidewalks to be paved shall be completed as
soon as possible.
• Structural pads shall be laid as soon as possible after grading unless seeding
or soil binders are used.
• Idling times shall be minimized either by shutting equipment off when not in

Table 3 shows the proposed Project’s mitigated construction emissions.

Source: LSA (February 2018).
As indicated in Table 3, with implementation of Mitigation Measure AIR-1, construction of the
proposed Project would not exceed daily emissions thresholds. Therefore, air quality impacts
associated with construction of the proposed Project would be less than significant.
Operational Emissions – Regional Emissions Analysis
Operational air emission impacts are typically associated with stationary and mobile sources.
Stationary source emissions result from the consumption of natural gas and electricity. Mobile
source emissions result from vehicle trips. The proposed Project would replace an existing bridge to
improve safety and efficiency. No stationary sources are associated with the proposed Project. In
addition, the proposed Project would not result in new vehicle trips or significantly increase VMT.

Therefore, once completed, the proposed Project would not generate significant operational
emissions. Long-term operation of the proposed Project would not contribute substantially to an
existing or projected air quality violation. Operational impacts would be less than significant.
Localized CO Impacts
Emissions and ambient concentrations of CO have decreased dramatically in the Bay Area with the
introduction of the catalytic converter in 1975. No exceedances of the State or federal CO standards
have been recorded at Bay Area monitoring stations since 1991. The BAAQMD 2017 CEQA
Guidelines include recommended methodologies for quantifying concentrations of localized CO
levels for proposed transportation projects (BAAQMD 2017). A screening level analysis using
guidance from the BAAQMD CEQA Guidelines was performed to determine the impacts of the Plan.
The screening methodology provides a conservative indication of whether the implementation of a
proposed project would result in significant CO emissions. According to the BAAQMD CEQA
Guidelines, a proposed project would result in a less-than-significant impact to localized CO
concentrations if the following screening criteria are met:
• The project is consistent with an applicable congestion management program established by the
county congestion management agency for designated roads or highways, and the regional
transportation plan and local congestion management agency plans.
• Project traffic would not increase traffic volumes at affected intersections to more than 44,000
vehicles per hour.
• The project would not increase traffic volumes at affected intersections to more than 24,000
vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel,
parking garage, bridge underpass, natural or urban street canyon, or below-grade roadway).
Implementation of the proposed Project would not conflict with the Transportation Authority of
Marin (TAM) for designated roads or highways, a regional transportation plan, or other agency
plans. The Project site is not located in an area where vertical or horizontal mixing of air is
substantially limited. As identified above, the proposed Project would not result in an increase in
vehicle trips or VMT. Therefore, the proposed Project would not increase traffic volumes at
intersections to more than 44,000 vehicles per hour and intersection level of service would not
decline with implementation of the proposed Project. Therefore, the proposed Project not result in
localized CO concentrations that exceed State or federal standards and this impact would be less
than significant.
c. Would the project result in a cumulatively considerable net increase of any criteria pollutant for
which the project region is non- attainment under an applicable federal or state ambient air
quality standard (including releasing emissions which exceed quantitative thresholds for ozone
precursors)?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. As discussed above, with
implementation of Mitigation Measure AIR-1, construction of the proposed Project would not result

in significant levels of criteria air pollutants or pollutant precursors, while operation of the Project
would not generate air emissions. Therefore, construction and operation of the proposed Project
would not significantly contribute to cumulative levels of pollution in the Air Basin. This impact
would be less than significant.
d. Would the project expose sensitive receptors to substantial pollutant concentrations?
LESS THAN SIGNIFICANT IMPACT. Sensitive receptors are defined as residential uses, schools,
daycare centers, nursing homes, and medical centers. Individuals particularly vulnerable to diesel
particulate matter are children, whose lung tissue is still developing, and the elderly, who may have
serious health problems that can be aggravated by exposure to diesel particulate matter. Exposure
from diesel exhaust associated with construction activity contributes to both cancer and chronic
non-cancer health risks.
According to the BAAQMD, a project would result in a significant impact if it would: individually
expose sensitive receptors to TACs resulting in an increased cancer risk greater than 10.0 in one
million, an increased non-cancer risk of greater than 1.0 on the hazard index (chronic or acute), or
an annual average ambient PM2.5 increase greater than 0.3 micrograms per cubic meter (µg/m3). A
significant cumulative impact would occur if the project, in combination with other projects located
within a 1,000-foot radius of the project site, would expose sensitive receptors to TACs resulting in
an increased cancer risk greater than 100 in one million, an increased non-cancer risk of greater
than 10.0 on the hazard index (chronic), or an ambient PM2.5 increase greater than 0.8 µg/m3 on an
annual average basis. Impacts from substantial pollutant concentrations are discussed below and
would be less than significant.
The closest sensitive receptors include single-family residential uses located approximately 30 feet
east of the proposed Project. Construction of the proposed Project may expose surrounding
sensitive receptors to airborne particulates, as well as a small quantity of construction equipment
pollutants (i.e., usually diesel-fueled vehicles and equipment). However, due to the linear nature of
the proposed Project, emissions would not be concentrated in any one area. Additionally,
construction contractors would be required to implement Mitigation Measure AIR-1, which would
further reduce potential impacts. Project construction emissions would be below the BAAQMD
significance thresholds and once the Project is constructed, the Project would not be a source of
substantial emissions. Therefore, sensitive receptors are not expected to be exposed to substantial
pollutant concentrations during Project construction or operation, and potential impacts would be
considered less than significant.
e. Would the project create objectionable odors affecting a substantial number of people?
LESS THAN SIGNIFICANT IMPACT. Land uses commonly considered to be potential sources of
obnoxious odorous emissions include wastewater treatment plants, sanitary landfills,
composting/green waste facilities, recycling facilities, petroleum refineries, chemical manufacturing
plants, painting/coating operations, rendering plants, and food packaging plants. Some
objectionable odors could be generated from the operation of diesel-powered construction
equipment during the Project construction period. However, these odors would be short-term in

receptors in the vicinity of the Project site. Implementation of the proposed Project would not

3.4.1 Environmental Setting
LSA prepared a Natural Environmental Study (Minimal Impacts) for the proposed Project in August
2017 (see Appendix B). The information for the following section is based on this study.
3.4.1.1 Methods
Prior to conducting any field studies, the limits of the Biological Study Area (BSA) were established,
totaling approximately 0.36 acres, including portions of Southern Heights Boulevard and adjacent
lands both east and west of the bridge. The BSA consists of the project footprint, temporary access
areas, and lands beyond the edge of the road right-of-way that could potentially be affected by
project construction and/or were determined necessary to inventory in order to perform an
adequate analysis of project impacts.
The studies required to fully document the environmental conditions of the BSA included a general
biological survey, habitat mapping, and tree inventory.

A list of sensitive wildlife and plant species potentially occurring within the BSA and vicinity was
compiled to evaluate potential impacts resulting from project construction. Sources used to compile
the list include the California Natural Diversity Data Base (CNDDB 2017), the U.S. Fish and Wildlife
Service (USFWS) Information for Planning and Conservation Trust Resources (USFWS 2017), the
California Native Plant Society (CNPS 2017) Online Inventory, and the National Marine Fisheries
Service (NMFS) Google Earth Species list (NMFS 2017). Records were reviewed for the San Rafael
U.S. Geological Survey 7.5-minute quadrangle.
For the NMFS Species list, the San Rafael quad was identified within the range of anadromous fish
species. The NMFS species list is an intersection of Federal Endangered Species Act Listed Species,
Critical Habitat, Essential Fish Habitat and Marine Mammal Protection Act Species Data within
California. It should be noted that identified features may be present throughout the entire
quadrangle or only a portion of it. All species lists are included in Appendix B.
The special status species lists obtained from the CNDDB, CNPS, USFWS and NMFS were reviewed to
determine which species could potentially occur within the vicinity of the BSA. The determination of
whether a species could potentially occur within the BSA was based on the availability of suitable
habitat within and adjacent to the BSA, as well as known occurrences of the species in or adjacent to
the BSA according to the CNDDB. Those species that could potentially occur in the BSA from habitat
suitability or on known occurrences in or within the vicinity of the BSA are discussed below, as
applicable.
A general biological survey of the BSA was conducted by LSA biologist Anna Van Zuuk on May 22,
2017. Mrs. Van Zuuk surveyed the BSA on foot. The naturally occurring vegetation in the BSA was
classified according to A Manual of California Vegetation, Second Edition (Sawyer, Keeler-Wolf, and
Evans 2008), as appropriate. Managed, disturbed, or developed areas were classified according to
their dominant plant species. The names of the plant species are consistent with The Jepson
Manual: Vascular Plants of California, Second Edition (Baldwin, B. G., et. al., editors 2012). An
inventory of native trees was also conducted by Mrs. Van Zuuk on May 22, 2017. Data was collected
on species, diameter at breast height, and any notable characteristics.
No potential waters of the U.S. were identified in the BSA; therefore, a jurisdictional delineation was
not conducted.
3.4.1.2 Results
The BSA is heavily disturbed and consists almost entirely of residential development, landscaping,
and ruderal/disturbed areas. One natural community, California Bay Forest, occurs west of the
existing bridge and extends downslope (see Figure 3). There are no aquatic features in the BSA. The
bridge spans a steep ravine that slopes east to west with an elevation that ranges from
approximately 260 to 300 feet above mean sea level.
Land uses in the immediate vicinity consist of moderate density residential housing scattered within
steep canyons in Coastal oak woodlands. These communities give way to dense urban and suburban
areas.

One natural community occurs within the BSA: California Bay Forest. Other habitat types not
considered natural include ruderal/disturbed, landscaped, and developed.
The California bay forest community, totaling 0.12 acre, occurs west of the Southern Heights Bridge
and continues downslope. This area has a tree canopy dominated by California bay (Umbellaria
californica) with a few Coast live oak (Quercus agrifolia) intermixed. The understory is sparse and
dominated by Upright veldt grass (Ehrharta erecta) with a few scattered toyon (Heteromeles
arbutifolia), madrone (Arbutus menziesii), and California buckeye (Aesculus californica) shrubs.
The ruderal/disturbed community, totaling 0.07 acre, is likely a former natural community that has
been subject to regular disturbance and now has a large component of ruderal species. The
vegetation that grows in these areas typically consists of species that are able to quickly colonize
following disturbance and can grow in poor soil conditions. In the BSA, ruderal/disturbed areas total
0.07 acre and occur west of Southern Heights Boulevard on roadsides and continuing downslope.
Dominant plant species include: rattlesnake grass (Briza maxima), ripgut brome (Bromus diandrus),
Italian thistle (Carduus pycnocephalus), and French broom (Genista monspessulana); dogtail grass
(Cynosurus echinatus), Italian ryegrass (Festuca perennis), foxtail barley (Hordeum murinum), hedge
mustard (Sisymbrium officinale), and hedge parsley (Torilis arvensis) are also present.
Landscaping, totaling approximately 0.06 acre, is located east of Southern Heights Boulevard and
the Southern Heights Bridge. Plants associated with this community are introduced and intensely
managed by residential land owners. Species present include: agapanthus (Agapanthus sp.), century
plant (Agave americana), yellow jade plant (Crassula ovata), jasmine (Jasminum sp.), paperwhites
(Narcissus papyraceus), prickly pear cactus (Opuntia sp.), white bower vine (Pandorea jasminoides),
rosemary (Rosmarinus officinalis), Mexican bush sage (Salvia leucantha) and calla lily (Zantedeschia
sp.).
The developed areas in the BSA, totaling approximately 0.11 acre, consist of Southern Heights
Boulevard, the Southern Heights Bridge, and private driveways and walkways.
No special status plant or animal species were observed or are expected to occur in the BSA. See
Appendix B for more details.
Wildlife movement corridors are linear habitats that function to connect two or more areas of
significant wildlife habitat. These corridors may function on a local level as links between small
habitat patches (e.g., streams in urban settings) or may provide critical connections between
regionally significant habitats (e.g., deer movement corridors). Wildlife corridors typically include
vegetation and topography that facilitate the movements of wild animals from one area of suitable
habitat to another in order to fulfill foraging, breeding, and territorial needs. These corridors often
provide cover and protection from predators that may be lacking in surrounding habitats. Wildlife
corridors generally include riparian zones and similar linear expanses of contiguous habitat.
Undeveloped lands in the vicinity of the BSA are intermixed with developed lands and are highly
fragmented; therefore, these lands do not provide suitable migration corridors for wildlife.

Runoff from Southern Heights Boulevard is collected and flows through a culvert downslope into an
adjoining neighborhood, ultimately outletting into Corte Madera Creek which drains into San
Francisco Bay. The ravine spanned by the Southern Heights Bridge may convey surface runoff during
the wet season, flowing west, but shows no evidence of hydrology. Therefore, no aquatic resources
were identified within the BSA.
3.4.2 Impact Analysis
a. Would the project have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or special-status species in
local or regional plans, policies, or regulations, or by the California Department of Fish and
Wildlife or U.S. Fish and Wildlife Service?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. No special status plant or
animal species were observed or are expected to occur in the BSA. However, the Project would
result in impacts to California bay forest and result in the removal of ten trees. Disturbance of
migratory birds during their nesting season (February 1 to August 31) could result in “take” which is
prohibited under the Migratory Bird Treaty Act and Section 3513 of the California Fish and Game
Code (CFGC). CFGC Section 3503 also prohibits take or destruction of bird nests or eggs. Since
Project construction is located in the vicinity of trees and would result in the removal of ten trees,
Mitigation Measure BIO-1 is recommended to reduce the potential for impacts to migratory birds.
With implementation of Mitigation Measure BIO-1, impacts would be less than significant.
Mitigation Measure BIO-1: If work must begin during the nesting season (February
1 to August 31), a qualified biologist shall survey all suitable nesting habitat in the
BSA for presence of nesting birds. This survey shall occur no more than 10 days prior
to the start of construction. If no nesting activity is observed, work may proceed as
planned. If an active nest is discovered, a qualified biologist shall evaluate the
potential for the proposed project to disturb nesting activities. The evaluation
criteria shall include, but are not limited to, the location/orientation of the nest in
the nest tree, the distance of the nest from the BSA, the line of sight between the
nest and the BSA, and the feasibility of establishing no-disturbance buffers.
Additionally, the California Department of Fish and Wildlife shall be contacted to
review the evaluation and determine if the project can proceed without adversely
affecting nesting activities.
If work is allowed to proceed, a qualified biologist shall be on-site weekly during
construction activities to monitor nesting activity. The biologist shall have the
authority to stop work if it is determined the project is adversely affecting nesting
activities.

b. Would the project have a substantial adverse effect on any riparian habitat or other sensitive
natural community identified in local or regional plans, policies, regulations, or by the California
Department of Fish and Wildlife or U.S. Fish and Wildlife Service?
NO IMPACT. No riparian habitat or other sensitive natural communities occur in the BSA. Therefore,
no impacts would occur.
c. Would the project have a substantial adverse effect on federally protected wetlands as defined
by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal,
etc.) through direct removal, filling, hydrological interruption, or other means?
NO IMPACT. No aquatic resources, including federally protected wetlands, are located within the
BSA. Therefore, no impacts would occur.
d. Would the project interfere substantially with the movement of any native resident or migratory
fish or wildlife species or with established native resident or migratory wildlife corridors, or
impede the use of native wildlife nursery sites?
NO IMPACT. Wildlife movement corridors are linear habitats that function to connect two or more
areas of significant wildlife habitat. These corridors may function on a local level as links between
small habitat patches (e.g., streams in urban settings) or may provide critical connections between
regionally significant habitats (e.g., deer movement corridors). Wildlife corridors typically include
vegetation and topography that facilitate the movements of wild animals from one area of suitable
habitat to another, in order to fulfill foraging, breeding, and territorial needs. These corridors often
provide cover and protection from predators that may be lacking in surrounding habitats. Wildlife
corridors generally include riparian zones and similar linear expanses of contiguous habitat.
Undeveloped lands in the vicinity of the BSA are intermixed with developed lands and are highly
fragmented; therefore, these lands do not provide suitable migration corridors for wildlife. No impact
would occur.
e. Would the project conflict with any local policies or ordinances protecting biological resources,
such as a tree preservation policy or ordinance?
NO IMPACT. The project will result in impacts to California bay forest, consisting of 0.02 ac of
permanent impacts and 0.09 ac of temporary impacts. The Project will result in the removal of eight
California bay trees, one oak, and one Pacific madrone. According to the City of San Rafael Tree
Ordinance, any City employees acting under the scope of their employment by the City are not
subject to the requirements of the Ordinance. The City of San Rafael is the proponent of this Project,
and therefore mitigation for the loss of the trees is not required as the tree ordinance is not
applicable. No impact would occur.

Community Conservation Plan, or other approved local, regional, or state habitat conservation

archaeological resource pursuant to §15064.5?
c. Directly or indirectly destroy a unique paleontological
resource or site or unique geologic feature?
d. Disturb any human remains, including those interred
outside of formal cemeteries?
3.5.1 Environmental Setting
LSA prepared a Historical Property Survey Report and Historical Resources Evaluation Report, and
Evans & De Shazo, LLC (EDS) prepared an Archaeological Survey Report for the proposed Project
(see Appendix C). These studies consisted of background research, consultation with potentially
interested parties, and a field survey. The information for the following section was based on these
three studies.
3.5.1.1 Cultural Resources
Research was conducted regarding historical properties and Native American cultural sites in an
Area of Potential Effect (APE) associated with the proposed Project. For the purposes of this Project,
two APEs were established: an Archaeological APE that includes all areas that will be directly
affected by the Project’s proposed ground disturbing activities, and an Architectural History APE,
which includes the area of direct effect but also takes into account all adjacent parcels that contain
built environment resources which have the potential to be indirectly affected by the proposed
Project. The Archaeological APE for the proposed Project is approximately 436 feet long and 60 feet
wide, over approximately 0.6 acres. EDS conducted a record search of the Archaeological APE on
March 30, 2017, at the Northwest Information Center (NWIC) of the California Historical Resources
Information System, Sonoma State University in Rohnert Park. The records search included the
Archaeological APE and a ½-mile radius for previous cultural resource studies and cultural sites. Two
cultural resources were recorded within the ½-mile search radius. According to the California Office
of Historic Preservation Archaeological Determination of Eligibility List, neither resource has been
evaluated to determine its eligibility for listing in the National Register of Historic Places (NRHP).
Consultation with the Native American Heritage Commission occurred on April 3, 2017, and the
results indicated that a records search of the Sacred Lands File was negative. EDS contacted two
local Native American Tribe representatives (both from the Federated Indians of Graton Rancheria)
on April 19, 2017, regarding the location of the proposed Project. Buffy McQuillen, the Tribal
Heritage Preservation Officer (THPO) for FIGR responded on May 10, 2017, stating that the Tribe
would review the project within 10 business days. In a subsequent email on May 22, 2017, Ms.
McQuillen stated that “the project is likely to impact tribal cultural resources important to the Tribe,

with additional concern that human remains may be nearby. The Tribe would like to participate in
the survey phase if it has not been completed at this time.” Sally Evans of EDS responded to Ms.
McQuillen on May 24, 2017, stating that the field survey had already been conducted for the
project, but provided a copy of the draft Archaeological Survey Report (ASR) for the Tribe to review,
noting that she would incorporate the comments regarding the Tribe’s concerns that human
remains may be nearby into the report. Ms. Evans also offered to arrange a field visit should the
Tribe be interested in visiting the site. No response was received from Ms. McQuillen or another
representative. Ms. Evans followed up with Ms. McQuillen on September 21, 2017 via email to ask if
the ASR had been reviewed and offered continuing consultation regarding the Tribe’s concern that
tribal cultural resources could be impacted by the Project. On October 2, 2017, Ms. Evans followed
up with Ms. McQuillen via email and again provided the draft ASR, and requested a day and time for
a phone call to ensure the Tribe’s concerns are fully addressed. No response has been received from
Ms. McQuillen to date.
Archaeological Sensitivity
The archaeological resources study consisted of archival and background research, field survey of
the APE on April 4, 2017, consultation with potentially interested parties, and an archaeological
sensitivity assessment. EDS assessed the Archaeological APEs archaeological sensitivity based on the
results of the records search, geological and soils research, and field survey. The records search
identified two previously identified archaeological deposits within ½-mile of the Archaeological APE.
The Jurassic-Cretaceaous age of the landform, in addition to extensive erosion events associated
with the landform, indicates that the Archaeological APE is not sensitive for surface or buried
archaeological deposits. One isolated artifact was encountered within and adjacent to the APE,
consisting of a 10-pound iron dumbbell that was observed on the ground surface under the existing
bridge structure. This artifact meets the criteria for exemption in the Section 106 Programmatic
Agreement and does not qualify as a property type eligible for listing on the NRHP or meet the
definition of a historical resource under CEQA. No potentially significant archaeological resources,
including prehistoric or historic archaeological sites, were identified within or adjacent to the
Archaeological APE. The Archaeological APE was determined not to be sensitive for surface or buried
archaeological deposits because the landform predates human occupation in North America and has
experienced extensive erosion.
Built Environment Resources
Pre-field, background, and resource-specific research pertaining to the history of the Architectural
History APE was conducted, as well as in-depth research related to historical themes and contexts
associated with the surrounding planned environment and its development. EDS identified a total of
six built environment resources that include five buildings dating between 1907 and 1951 and the
Southern Heights Bridge (Bridge No. 27CO148) constructed circa 1930. All six built environment
resources evaluated were determined to be ineligible for listing on the NRHP. Three of the built
environment resources were previously identified as part of the City of San Rafael’s 1978 Historic
Resources Inventory (HRI) and listed in the 1986 San Rafael Historical/Architectural Survey (City of
San Rafael 1986); therefore, they are considered historical resources for purposes of CEQA per

§15064.5(a)(2). However, none of the six resources are eligible for listing in the California Register of
Historic Resources (CRHR) or the NRHP.
Historic-era artifacts were observed during the survey of the Architectural History APE; however,
these artifacts are outside of the Area of Direct Impact (ADI) and Archaeological APE and will be
neither directly nor indirectly affected by the Project. There is no potential for indirect effects
because they are located too far away to be impacted by vibration and the Project will not result in
increased public access which would put it at risk for vandalism or looting.
3.5.2 Impact Analysis
a. Would the project cause a substantial adverse change in the significance of a historical resource
as defined in §15064.5?
LESS THAN SIGNIFICANT WITH MITIGATION INCORPORATED. As discussed above, three built
environment resources are identified within the City’s HRI and are considered historical resources
for the purposes of CEQA because they were identified in the City’s survey. The proposed Project
includes the replacement of an existing bridge along Southern Heights Boulevard. The bridge
replacement would be located within the City’s ROW and would not require expansion of the
existing ROW. Two of the resources listed in the City’s HRI are properties significant for their
architectural qualities that are located adjacent to the bridge. These two historical resources would
not be affected by the Project as they are outside of the City’s ROW and will not be physically
altered, damaged, or destroyed by the Project. The remaining resource listed in the City’s HRI is the
Southern Heights Bridge itself. While the bridge is listed in the City’s HRI, further research concluded
that it is not eligible for listing in the CRHR or NRHP. As the City has listed the bridge in the HRI, the
City has the jurisdiction to determine whether or not the bridge shall be considered an historical
resource. The City uses the HRI as a guide for determining which properties may be considered
historical resources for the purpose of CEQA. Based on the findings of the updated research and
analysis conducted for the Historic Resources Evaluation Report, the City does not consider the
bridge an historical resource for the purposes of CEQA. Therefore, impacts to known historical
resources would be less than significant.
While unlikely, the possibility exists that previously unknown buried archaeological deposits could
be discovered during grading and excavation work associated with construction. Prehistoric
materials can include flaked-stone tools (e.g., projectile points, knives, choppers) or obsidian, chert,
basalt or quartzite tool making debris; bone tools; culturally darkened soil (e.g., midden soil often
containing heat-affected rock, ash and charcoal, shellfish remains, faunal bones, and cultural
materials); and stone milling equipment (e.g., mortars, pestles, handstones). Prehistoric
archaeological sites often contain human remains. Historical materials can include wood, stone,
concrete, or adobe footings, walls and other structural remains; debris-filled wells or privies; and
deposits of wood, glass, ceramics, metal and other refuse. Implementation of Mitigation Measure
CULT-1 would reduce impacts to previously undiscovered resources to a less than significant level.
Mitigation Measure CULT-1: If any archaeological or paleontological deposits are
encountered, all work within 25 feet of the discovery shall be redirected and a
qualified archaeologist contacted, if one is not present, to assess the situation,

consult with agencies as appropriate, and make recommendations for the treatment
of the discovery. The City of San Rafael shall also be notified. Project personnel shall
not collect or move any archaeological materials.
Any adverse impacts to the finds shall be avoided by Project activities. If avoidance
is not feasible, the archaeological deposits shall be evaluated to determine if they
qualify as a historical resource or unique archaeological resource, or as historic
property. If the deposits do not so qualify, avoidance is not necessary. If the
deposits do so qualify, adverse impacts on the deposits shall be avoided, or such
impacts shall be mitigated. Mitigation may consist of, but is not limited to, recovery
and analysis of the archaeological deposit; recording the resource; preparing a
report of findings; and accessioning recovered archaeological materials at an
appropriate curation facility. Educational public outreach may also be appropriate.
Upon completion of the assessment, the archaeologist shall prepare a report
documenting the methods and results, and provide recommendations for the
treatment of the archaeological deposits discovered. The report shall be submitted
to the City of San Rafael.
b. Would the project cause a substantial adverse change in the significance of an archaeological
resource pursuant to §15064.5?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. No archaeological resources,
as defined by §15064.5, have been identified in the Project area. Archaeological resources are not
anticipated to be discovered during Project activities. If, however, such resources are discovered,
implementation of Mitigation Measure CULT-1 described above, would reduce potential impacts to
a less than significant level.
c. Would the project directly or indirectly destroy a unique paleontological resource or site or
unique geologic feature?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. No paleontological resources
or unique geologic features are known to exist within the APE. However, should paleontological
resources be discovered during Project construction, implementation of Mitigation Measure
PALEO-1 would reduce potential impacts to paleontological resources to a less than significant level.
Mitigation Measure PALEO-1: If paleontological resources are encountered during
Project subsurface construction and no monitor is present, all ground-disturbing
activities shall be redirected within 50 feet of the find until a qualified paleontologist
can be contacted to evaluate the find and make recommendations. If found to be
significant and proposed Project activities cannot avoid the paleontological
resources, a paleontological evaluation and monitoring plan, as described above,
shall be implemented. Adverse impacts to paleontological resources shall be
mitigated, which may include monitoring, data recovery and analysis, a final report,
and the accession of all fossil material to a paleontological repository. Upon

completion of Project ground-disturbing activities, a report documenting methods,
findings, and recommendations shall be prepared and submitted to the
paleontological repository.
d. Would the project disturb any humans remains, including those interred outside of formal
cemeteries?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. No human remains are
known to exist within the APE. Section 7050.5 of the California Health and Safety Code states that in
the event of discovery or recognition of any human remains in any location other than a dedicated
cemetery, there shall be no further excavation or disturbance of the site or any nearby area
reasonably suspected to overlie adjacent remains until the coroner of Marin County has determined
whether or not the remains are subject to the coroner’s authority. There is no indication that human
remains are present within the Project site. Implementation of Mitigation Measure CULT-2 would
ensure that potential impacts to human remains, should they be encountered, would be reduced to
a less than significant level.
Mitigation Measure CULT-2: In the event that human remains are encountered,
work within 50 feet of the discovery shall be redirected and the Marin County
Coroner notified immediately. At the same time, a qualified archaeologist shall be
contacted to assess the situation and consult with agencies as appropriate. Project
personnel shall not collect or move any human remains and associated materials. If
the human remains are of Native American origin, the coroner shall notify the
Native American Heritage Commission within 24 hours of this identification. The
Native American Heritage Commission shall identify a Most Likely Descendant (MLD)
to inspect the site and provide recommendations for the proper treatment of the
remains and associated grave goods. Upon completion of the assessment, the
archaeologist shall prepare a report documenting the methods and results, and
provide recommendations of the treatment of the human remains and any
associated cultural materials, as appropriate and in coordination with the
recommendations of the MLD. The report shall be submitted to the City of San
Rafael.

3.6.1 Environmental Setting
3.6.1.1 Geology
San Rafael is located within the Coast Range geomorphic province of California. According to the San
Rafael General Plan 2020 Draft Environmental Impact Report (San Rafael General Plan EIR), the
“regional bedrock geology consists of complexly folded, faulted, sheared, and altered sedimentary,
igneous, and metamorphic rock of the Jurassic-Cretaceous age (65-190 million years ago) Franciscan
Complex” (City of San Rafael 2004).
The Project site is located in an area with steep, sloping topography. Elevation on the Project site
ranges from 230 to 300 feet above mean sea level.
3.6.1.2 Soils
The Project site is comprised of one soil: Tocaloma-McMullin complex, 30 to 50 percent slopes.
Tocaloma is found on hills and its parent material is residuum weathered from sandstone and shale.
McMullin is found on hills and its parent material is residuum weathered from conglomerate.
Additional attributes of this soil are described in Table 4, some of which are explained in more detail
below.

Hydrologic Soil Group. Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups based on the rate of water infiltration when the soils are not
protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.
Soils within the Project site are assigned to Hydrological Soil Group B or D, as the Tocaloma-
McMullin complex is made up of two soils. Hydrologic Soil Group B is defined as “soils having a
moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep,
moderately well drained or well drained soils that have moderately fine texture to moderately
coarse texture. These soils have a moderate rate of water transmission” (NRCS 2018). Hydrologic
Soil Group D is defined as “soils having a very slow infiltration (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have
a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are
shallow over nearly impervious material. These soils have a very slow rate of water transmission.
Erosion Factor (K Factor), Whole Soil. Erosions factor K indicates the susceptibility of a soil to sheet
and rill erosion by water. Sheet erosion removes a layer of exposed surface soil (topsoil) by the
action of rainfall splash and runoff. Rill erosion develops as flowing runoff concentrates in grooves,
called rills, which cut several inches into the soil surface. Rills grow to deeper and wider gullies
where concentrated flow of water moves over the soil. Loss of soil is also dependent on the soil
type, surface slope and vegetative cover. Values of K range from 0.02 to 0.69 and in general, the
higher the value, the more susceptible the soil is to sheet and rill erosion by water. Therefore, soils
on the Project site have a low susceptibility to sheet and rill erosion by water (NRCS 2018).
Linear Extensibility. Linear extensibility (shrink-swell potential) is an expression of the volume
change of an unconfined clod as moisture content is decreased from a moist to a dry state. The
amount and type of clay minerals in the soil influence volume change. When the soil takes on water,
the volume change is reported as percent change for the whole soil. The linear extensibility rating
for the Project site soils is 1.5 percent, which indicates a low shrink-swell potential.
3.6.1.3 Seismicity
According to the San Rafael General Plan EIR, San Rafael is located within a seismically active area
that will experience effects of future earthquakes. However, there are no known active faults within
the City of San Rafael’s planning area and the estimated historic earthquake accelerations

experienced in the area are relatively low compared to other cities in the San Francisco Bay Area
(City of San Rafael 2004).
The California Geologic Survey Probabilistic Seismic Hazard Assessment calculates earthquake
shaking hazards using historic seismic activity and fault slip rate data. Shaking from faults is
expressed as the Peak Ground Acceleration (PGA) measured as a percentage (or fraction) of
acceleration due to gravity (%g) from ground motion that has a 10 percent probability of being
exceeded in 50 years. The Project site is located in an area with a PGA of 48.5 percent (0.485g) (DOC
2008).
The Alquist-Priolo Fault Zoning Act provides policies and criteria to assist cities, counties and State
agencies in restricting development on active faults. The Alquist-Priolo Act requires the State
geologist to delineate regulatory zones that encompass all potentially and recently active traces of
named faults and other such faults, or fault segments that are deemed sufficiently active and well-
defined as to constitute a potential hazard to structures from surface faulting or fault creep. The
Project site is not located within an Alquist-Priolo Fault Zone. The closest Alquist-Priolo Fault Zone to
the Project site is the San Andreas Fault Zone, located approximately 9 miles to the west.
Seismic Hazards
Liquefaction. Liquefaction is a process by which water-saturated sand and silt temporarily lose
strength and act as a liquid during strong seismic shaking events. According to the USGS
Earthquake Hazards Program, the Project area has very low liquefaction susceptibility (USGS
n.d.).
Landslides. Landslides generally occur in areas with steep slopes, where underlying materials
have become weak or fractured as a result of erosion, snowmelt or heavy rains, earthquakes, or
other factors. The Project area may be susceptible to landslides due to the steep slopes in the
Project vicinity.
3.6.2 Impact Analysis
a. Would the project expose people or structures to potential substantial adverse effects, including
the risk of loss, injury, or death involving:
i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo
Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other
substantial evidence of a known fault? Refer to Division of Mines and Geology Special
Publication 42.
LESS THAN SIGNIFICANT IMPACT. Surface rupture occurs when the ground surface is broken due to
fault movement during an earthquake. The location of surface rupture generally can be assumed to
be along an active or potentially active major fault trace. The Project site is located outside the
designated Alquist-Priolo Fault Zones for active faulting and no mapped evidence of active or
potentially active faulting was found for the site in the Preliminary Foundation Report (Parikh
Consultants, Inc. 2017). Therefore, the potential for fault rupture at the site is low. Implementation

of the proposed Project would not adversely affect persons or structures due to rupture of a known
earthquake fault. Impacts would be less than significant.
ii. Strong seismic ground shaking?
LESS THAN SIGNIFICANT IMPACT. The Project site is located in a seismically active part of California.
Many faults existing in northern California are capable of producing earthquakes and may cause
strong ground shaking at the site. However, the proposed Project would be engineered and
designed based on the Caltrans Seismic Design Criteria, which includes measures for bridges to
reduce their susceptibility to strong seismic shaking. Implementation of the proposed Project would
not adversely affect persons or structures due to strong seismic ground shaking. Impacts would be
less than significant.
iii. Seismic-related ground failure, including liquefaction?
LESS THAN SIGNIFICANT IMPACT. The liquefaction potential at the Project site was evaluated based
on boring data collected for the Preliminary Foundation Report. The Project site has a low potential
for liquefaction (Parikh Consultants, Inc. 2017). Implementation of the proposed Project would not
adversely affect persons or structures due to liquefaction. Impacts would be less than significant.
iv. Landslides?
LESS THAN SIGNIFICANT IMPACT. The proposed Project would not alter slopes in the Project area in
a manner that would increase the risk of landslides. Given the steep slopes in the Project vicinity,
the new bridge associated with the proposed Project would be designed in accordance with modern
engineering standards and supported on deep foundations. The new bridge structure would not
increase landslide risk above existing conditions. Therefore, implementation of the proposed Project
would not adversely affect persons or structures due to landslides. Impacts would be less than
significant.
b. Would the project result in substantial soil erosion or the loss of topsoil?
LESS THAN SIGNIFICANT IMPACT. The proposed Project would replace the existing bridge with a
new structure. Construction of the bridge would involve excavation for and construction of concrete
abutments and piers. Construction activities could spur short-term wind-driven erosion. However,
the proposed Project would be subject to the requirements set forth by the City, as well as the
Regional Water Quality Control Board’s best management practices, which will ensure that erosion
within the Project area would be controlled. The proposed Project is also subject to the
requirements set forth by the National Pollutant Discharge Elimination System Stormwater General
Construction Permit, which requires a Stormwater Pollution Prevention Plan (SWPPP) to monitor
and prevent soil erosion or the loss of top soil. Operations would have no impact on soil erosion or
loss of topsoil. In summary, the proposed Project would have a less than significant impact on soil
erosion and topsoil.

c. Would the project be located on a geologic unit or soil that is unstable, or that would become
unstable as a result of the project, and potentially result in on- or off-site landslide, lateral
spreading, subsidence, liquefaction or collapse?
LESS THAN SIGNIFICANT IMPACT. As described above, the potential hazards from liquefaction
events at the Project site are low, while the potential hazards from landslide events at the Project
site are moderate given the steep slopes and potential for seismic activity. The proposed Project
would be supported on deep foundations, and would not increase landslide risk in the Project area
above existing conditions. Therefore, impacts associated with seismic-related ground failure,
including liquefaction, subsidence, lateral spreading, and landslides would be less than significant.
d. Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform
Building Code (1994), creating substantial risks to life or property?
LESS THAN SIGNIFICANT IMPACT. The Project site is located atop soils with a low shrink-swell
potential. Therefore, impacts associated with expansive soils would be less than significant.
e. Would the project have soils incapable of adequately supporting the use of septic tanks or
alternative wastewater disposal systems where sewers are not available for the disposal of
wastewater?
NO IMPACT. The Project does not propose the use or construction of septic tanks or alternative
wastewater disposal systems. Such facilities are not needed, as the Project would be limited to
bridge replacement. The Project would have no impacts on the area’s ability to adequately support
the use of septic tanks or alternative wastewater disposal systems.

Would the project:
a. Generate greenhouse gas emissions, either directly or

environment?
b. Conflict with an applicable plan, policy or regulation
adopted for the purpose of reducing the emissions of
greenhouse gases?
3.7.1 Environmental Setting
Greenhouse gases (GHG) are present in the atmosphere naturally, are released by natural sources,
or are formed from secondary reactions taking place in the atmosphere. The gases that are widely
seen as the principal contributors to human-induced global climate change are:
• Carbon dioxide (CO2);
• Methane (CH4);
• Nitrous oxide (N2O);
• Hydrofluorocarbons (HFC);
• Perfluorocarbons (PFC); and
• Sulfur Hexafluoride (SF6).
Over the last 200 years, humans have caused substantial quantities of GHGs to be released into the
atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere and
enhancing the natural greenhouse effect, believed to be causing global warming. While manmade
GHGs include naturally-occurring GHGs such as CO2, methane, and N2O, some gases, like HFCs, PFCs,
and SF6 are completely new to the atmosphere.
Certain gases, such as water vapor, are short-lived in the atmosphere. Others remain in the atmos-
phere for significant periods of time, contributing to climate change in the long term. Water vapor is
excluded from the list of GHGs above because it is short-lived in the atmosphere and its atmospheric
concentrations are largely determined by natural processes, such as oceanic evaporation.
These gases vary considerably in terms of Global Warming Potential (GWP), a concept developed to
compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP is
based on several factors, including the relative effectiveness of a gas to absorb infrared radiation
and length of time that the gas remains in the atmosphere (“atmospheric lifetime”). The GWP of
each gas is measured relative to CO2, the most abundant GHG. The definition of GWP for a particular

GHG is the ratio of heat trapped by one unit mass of the GHG to the ratio of heat trapped by one
unit mass of CO2 over a specified time period. GHG emissions are typically measured in terms of
pounds or tons of “CO2 equivalents” (CO2e).
3.7.2 Impact Analysis
a. Would the project generate greenhouse gas emissions, either directly or indirectly, that may
have a significant impact on the environment?
LESS THAN SIGNIFICANT IMPACT. This section describes the proposed Project’s construction- and
operational-related GHG emissions and contribution to global climate change. The BAAQMD has not
addressed emission thresholds for construction in their CEQA Guidelines; however, the BAAQMD
encourages quantification and disclosure. Thus, construction emissions are discussed in this section.
Construction Activities
Construction activities associated with the proposed Project would produce combustion emissions
from various sources. During construction, GHGs would be emitted through the operation of
construction equipment and from worker and builder supply vendor vehicles, each of which typically
use fossil-based fuels to operate. The combustion of fossil-based fuels creates GHGs such as CO2,
CH4, and N2O. Furthermore, CH4 is emitted during the fueling of heavy equipment. Exhaust
emissions from on-site construction activities would vary daily as construction activity levels change.
The BAAQMD does not have an adopted threshold of significance for construction-related GHG
emissions. However, lead agencies are encouraged to quantify and disclose GHG emissions that
would occur during construction. Using CalEEMod, it is estimated that construction of the proposed
Project would generate approximately 637 metric tons of CO2e. Implementation of Mitigation
Measure AIR-1 would reduce GHG emissions by reducing the amount of construction vehicle idling
and by requiring the use of properly maintained equipment. Therefore, Project construction impacts
associated with GHG emissions would be considered less than significant.
Operational Emissions
As discussed above, the proposed Project would replace an existing bridge to improve safety and
efficiency. No stationary sources are associated with the proposed Project. The proposed Project
would not result in new vehicle trips or significantly increase VMT. Once completed, the proposed
Project would not generate substantial GHG emissions or result in substantial new vehicle trips that
would contribute to an increase in GHG emissions. Therefore, GHG emissions generated by the
proposed Project would be less than significant. No mitigation is required.

b. Would the project conflict with an applicable plan, policy or regulation adopted for the purpose
of reducing the emissions of greenhouse gases?
LESS THAN SIGNIFICANT IMPACT. The City of San Rafael’s Climate Change Action Plan 2 (CCAP),
adopted in 2009, establishes recommended programs for achieving a 25 percent reduction of GHGs
by 2020, and an 80 percent reduction by 2050 to meet State targets. The CCAP is broken down into
several distinct areas of action: Lifestyles, Buildings, Environment, Economy, Community Outreach,
and City Operations.
As discussed above, the long-term use of the Project is to replace an existing bridge to improve
safety and efficiency. The proposed Project does not fall within or promote a specific program
within the CCAP to reduce GHGs. However, the proposed Project would not result in new vehicle
trips or significantly increase VMT and therefore would not result in a substantial increase in GHG
emissions. Therefore, the proposed Project is consistent with the CCAP and would not generate
emissions that would exceed the project-level significance criteria established by the BAAQMD. The
Project would also not conflict with the programs included in the CCAP. Therefore, the proposed
Project would not conflict with plans, policies, or regulations adopted for the purpose of reducing
GHG emissions. This impact would be less than significant.

• Toxic
Land uses around the Project site include low-density residential, hillside residential, and open
space. Construction and development activities occurring at the Project site could potentially expose
residents to hazardous materials.
The Project site and nearby land uses are not located in an area that is included on a list of
hazardous material sites compiled pursuant to Government Code Section 65962.5. A search of the
California State Water Resources Control Board (SWRCB) GeoTracker website indicates no
hazardous materials sites are located within 1,000 feet of the Project site (SWRCB 2018).
3.8.2 Impact Analysis
a. Would the project create a significant hazard to the public or the environment through the
routine transport, use, or disposal of hazardous materials?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. The proposed Project would
not include the routine transport, use, or disposal of hazardous materials that could create a
significant hazard to the public. Hazardous materials (such as oil, fuel, and solvents) would be used
during construction activities for minor equipment maintenance. Any use of hazardous materials
would comply with all applicable local, state, and federal standards associated with the handling of
hazardous materials, to minimize the potential for exposure and hazards. All refueling of
construction vehicles and equipment would occur within the designated staging areas for the
proposed Project. The use of such hazardous materials would be temporary, and the proposed
Project would not include a permanent use or source of hazardous materials. Implementation of
Mitigation Measure HAZ-1 would reduce this impact to a less than significant level.
Mitigation Measure HAZ-1: The contractor shall prepare a Spill Prevention and
Countermeasure Plan (SPCP) and submit the SPCP to the City for review and
approval prior to the commencement of construction activities. The SPCP shall
include information on the nature of all hazardous materials that would be used on-
site. The SPCP shall also include information regarding proper handling of hazardous
materials, and clean-up procedures in the event of an accidental release. The phone
number of the agency overseeing hazardous materials and toxic clean-up shall be
provided in the SPCP.
b. Would the project create a significant hazard to the public or the environment through
reasonably foreseeable upset and accident conditions involving the release of hazardous
materials into the environment?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. Hazardous materials (e.g.,
fuel, lubricant, concrete curing materials) may be used by construction equipment and for proposed
Project improvements during construction. These materials would be used in accordance with all
applicable laws and regulations, and, if used properly, would not pose a hazard to people, animals,
or plants. The use of hazardous materials for construction equipment would be temporary, and the
proposed Project would not include a permanent use or source of hazardous materials.

Implementation of Mitigation Measure HAZ-1 would reduce any potentially significant impacts
associated with upset or accident conditions to a less than significant level.
c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous
materials, substances, or waste within one-quarter mile of an existing or proposed school?
LESS THAN SIGNIFICANT WITH MITIGATION INCORPORATED. Laurel Dell Elementary School is
located approximately 0.16 miles to the northeast. After Project construction, the newly constructed
bridge on Southern Heights Boulevard would operate similar to existing conditions; therefore,
operation of the proposed Project would not result in hazardous emissions or the handling of
hazardous materials, substances, or waste in the vicinity of an existing or proposed school. However,
replacement of the existing bridge with a new bridge structure could potentially require the
transport and use of hazardous materials. Implementation of Mitigation Measure HAZ-1 would
reduce any potentially significant impacts to a less than significant level.
d. Would the project be located on a site which is included on a list of hazardous materials sites
compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a
significant hazard to the public or the environment?
NO IMPACT. As described above, the proposed Project site is not on or near a site which is included
on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5.
Therefore, implementation of the proposed Project would not create a significant hazard to the
public or the environment; no impacts would occur.
e. Would the project be located within an airport land use plan or, where such a plan has not been
adopted, within 2 miles of a public airport or public use airport, would the project result in a
safety hazard for people residing or working in the project area?
NO IMPACT. The nearest public airport is Gnoss Field Airport, located over 12 miles north of the
Project site. The Project site is not located within an airport land use plan or within 2 miles of a
public airport or public use airport. No impact would occur.
f. For a project within the vicinity of a private airstrip, would the project result in a safety hazard
for people residing or working in the project area?
NO IMPACT. No private airstrips are located in the Project vicinity. No impact would occur.
g. Would the project impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
LESS THAN SIGNIFICANT IMPACT. The proposed Project includes the replacement of an existing
bridge structure along Southern Heights Boulevard. Once complete, the newly constructed bridge
would operate better than under existing conditions, as emergency service vehicle access would be
provided with the Project; therefore, operation of the Project would not impair implementation of
or physically interfere with an adopted emergency response plan or emergency evacuation plan.

h. Would the project expose people or structures to a significant risk of loss, injury or death
involving wildland fires, including where wildlands are adjacent to urbanized areas or where
residences are intermixed with wildlands?
LESS THAN SIGNIFICANT WITH MITIGATION INCORPORATED. Residences in the immediate Project
vicinity are listed on the City’s Wildland-Urban Interface (WUI), which lists areas where homes are
built near lands prone to wildland fire. Operation of the proposed Project would not increase the
risk for wildland fires in the Project area, as no new housing or businesses would be constructed.
Construction of the proposed Project would occur on slopes that include potentially flammable
vegetation, increasing the fire hazard risk. During construction, the most likely source of ignition
would be by mechanical activities such as operation of excavators and bulldozers. However, the
potential for ignition can be greatly reduced through equipment features, fuel treatment, and
management of behavior. Mitigation Measure HAZ-2 is recommended to reduce the risk associated
with fire hazards during Project construction. With implementation of Mitigation Measure HAZ-2,
the proposed Project would result in a less than significant impact related to exposing people or
structures to a significant risk of loss, injury or death involving wildland fires.
Mitigation Measure HAZ-2: The following measures shall be implemented
throughout the construction period to reduce the potential risk associated with fire
hazards:
• All construction workers shall undergo fire prevention training prior to working
on the site. The training shall describe fire prevention practices included below.
• Upon notification from the City Fire Department that a “Red Flag Warning –
High Fire Danger Alert” exists for the City, the contractor shall suspend any
construction activities involving powered mechanical equipment and shall limit
motorized vehicle access to construction staging areas.
• The contractor shall maintain fire suppression equipment, including water
pumpers and fire extinguishers onsite and on trucks and tractors.
• The contractor shall maintain communication equipment, including cell phones
and radios on site during construction to allow for rapid contact of emergency
responders.
• The contractor shall implement the following measures to reduce risk of fire
resulting from the use and storage of fuel:
o Refuel power equipment or tools in a cleared space;
o Store fuel in a cleared space and, where possible, in the shade;
o Turn off equipment while fueling;
o Use a gas spout/funnel to avoid spills; and
o Remove or dry any spilled fuel prior to starting equipment.

3.9.1 Environmental Setting
3.9.1.1 Surface Water
Major surface waters in the San Rafael Planning Area include the San Rafael and San Pablo Bays, San
Rafael Creek, Las Gallinas Creek, and Miller Creek. Runoff from Southern Heights Boulevard is
collected and flows through a culvert downslope into an adjoining neighborhood, ultimately
outletting into Corte Madera Creek which drains into San Francisco Bay. The ravine spanned by the
Southern Heights Bridge may convey surface runoff during the wet season, flowing west, but shows
no evidence of hydrology. Therefore, no surface waters are located at or adjacent to the Project site.
The nearest surface water is San Rafael Creek, located 0.3 miles north of the Project site.

3.9.1.2 Groundwater
According to the San Rafael General Plan EIR, groundwater resources in the San Rafael Planning
Area are very limited and groundwater “is either found in fractures in the Franciscan Formation or in
shallow alluvial deposits in valleys” (City of San Rafael 2004).
3.9.1.3 Floodplain
The Federal Emergency Management Agency has designated the Project area as Zone X (with no
overlay), which indicates areas of minimal flood hazard (FEMA 2016).
3.9.2 Impact Analysis
a. Would the project violate any water quality standards or waste discharge requirements?
Construction Impacts
LESS THAN SIGNIFICANT IMPACT. While no surface waters are located within the Project site, runoff
from Southern Heights Boulevard is collected and flows through a culvert downslope into an
adjoining neighborhood, ultimately outletting into Corte Madera Creek which drains into San
Francisco Bay. Proposed construction activities would disturb site soils, potentially resulting in soil
erosion and sedimentation of downstream waterways. Additionally, construction activities would
require the storage and use of hazardous materials and other urban pollutants such as gasoline,
diesel fuel, oils, solvents, and trash, which could enter drainages and degrade downstream water
quality and/or violate applicable water quality standards or waste discharge requirements.
The State Water Resources Control Board requires dischargers whose projects disturb 1 or more
acres of soil, or whose projects disturb less than 1 acre but are part of a larger common plan of
development that in total disturbs 1 or more acres, to obtain coverage under the General Permit for
Discharges of Storm Water Associated with Construction Activity (Construction General Permit 99-
08-DWQ). Effective July 1, 2010, all dischargers are required to obtain coverage under the
Construction General Permit Order 2009-0009-DWQ adopted on September 2, 2009. Construction
activity subject to this permit includes clearing, grading, and disturbances to the ground such as
stockpiling or excavation.
The Construction General Permit requires the development and implementation of a SWPPP. The
SWPPP must list best management practices (BMP) the discharger will use to protect stormwater
runoff and the placement of those BMPs. Additionally, the SWPPP must contain a visual monitoring
program and a chemical monitoring program for “non-visible” pollutants to be implemented if there
is a failure of the BMPs.
In addition, measures would be included in the grading plans to minimize erosion potential and
water quality degradation of the Project area in accordance with San Rafael Municipal Code Section
9.30.140 Construction-Phase Best Management Practices. Section 9.20.140 specifies that all
construction activities within the City shall implement appropriate BMPs to prevent the discharge of
construction wastes or contaminants from construction materials, tools, and equipment from
entering the storm drain system or watercourse. The City would identify the appropriate BMPs for

the proposed Project. Compliance with the provisions of the SWPPP and with Municipal Code
Section 9.30.140 would reduce impacts associated with water quality standards and discharge
requirements to a less than significant level.
Operational Impacts
LESS THAN SIGNIFICANT IMPACT. Long-term water quality impacts usually occur due to changes in
stormwater drainage or increases in impervious surfaces. The proposed Project would not
significantly increase the bridge footprint and therefore changes in stormwater drainage are not
expected. As a result, the proposed Project would not cause a permanent increase in degradation of
water quality and operational impacts would be less than significant.
b. Would the project substantially deplete groundwater supplies or interfere substantially with
groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of
the local groundwater table level (e.g., the production rate of pre-existing nearby wells would
drop to a level which would not support existing land uses or planned uses for which permits
have been granted)?
LESS THAN SIGNIFICANT IMPACT. The Project would not significantly increase the bridge footprint.
The small increase in impervious surfaces associated with the proposed Project is not anticipated to
deplete groundwater supplies or substantially interfere with groundwater recharge. During
construction, minimal amounts of water may be required for dust control activities. Water required
during construction activities would be transported to the Project site by water trucks and stored in
these trucks at the construction staging areas. Groundwater supplies would not be substantially
depleted nor would interference of groundwater recharge occur due to water usage during
construction. Once operational, the proposed Project would not require the use of water. Therefore,
the proposed Project’s impacts on groundwater recharge would be less than significant.
c. Would the project substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, in a manner which would result in
substantial erosion or siltation on- or off-site?
LESS THAN SIGNIFICANT IMPACT. The proposed Project includes the replacement of the existing
bridge structure along Southern Heights Boulevard. Existing drainage patterns in the Project vicinity
would not be substantially altered by construction of the proposed project. Onsite drainage patterns
are anticipated to remain relatively unchanged compared to current conditions. As a result, the
proposed Project would result in less than significant impacts from erosion or siltation caused by
alteration of existing drainage patterns.
d. Would the project substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, or substantially increase the rate or
amount of surface runoff in a manner which would result in flooding on- or off-site?
LESS THAN SIGNIFICANT IMPACT. See discussion under Question C above. Onsite drainage patterns
are anticipated to remain relatively unchanged compared to current conditions. As a result, the

proposed Project would result in less than significant impacts from flooding caused by alteration of
existing drainage patterns.
e. Would the project create or contribute runoff water which would exceed the capacity of existing
or planned stormwater drainage systems or provide substantial additional sources of polluted
runoff?
LESS THAN SIGNIFICANT IMPACT. The proposed Project would not significantly increase the bridge
footprint. Stormwater from Southern Heights Boulevard is currently collected and flows through a
culvert downslope into an adjoining neighborhood. The proposed Project would not result in a
substantial increase in stormwater generated onsite. Therefore, changes in stormwater drainage are
not expected. The Project would have a less than significant impact on stormwater drainage systems
and associated runoff.
f. Would the project otherwise substantially degrade water quality?
LESS THAN SIGNIFICANT IMPACT. See discussions under Questions A and C above. The Project
would not substantially degrade water quality and impacts would be less than significant.
g. Would the project place housing within a 100-year flood hazard area as mapped on a federal
Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map?
NO IMPACT. The proposed Project is not located within a 100-year flood hazard area, nor would it
involve the construction of housing. No impacts to housing associated with flood hazards would
occur.
h. Would the project place within a 100-year flood hazard area structures which would impede or
redirect flood flows?
NO IMPACT. The proposed Project is not located within a 100-year flood hazard area, nor would the
proposed bridge impede or redirect flood flows. No impacts associated with flood hazards would
occur.
i. Would the project expose people or structures to a significant risk of loss, injury or death
involving flooding, including flooding as a result of the failure of a levee or dam?
NO IMPACT. The proposed Project would not involve the development of residential or other
sensitive land uses in or near these areas. Therefore, the Project would not expose people or
structures to potential impacts involving flooding, including flooding as a result of the failure of a
levee or dam.
j. Would the project be inundated by seiche, tsunami, or mudflow?
LESS THAN SIGNIFICANT IMPACT. As described in the San Rafael General Plan EIR, the San Rafael
and western San Pablo Bay areas are partially protected and would not be subject to potential
flooding due to the generation of seiches. While it is possible that a 100-year tsunami event could

possibly reach the City of San Rafael, the Project would not involve the development of residential
or other sensitive land uses in this area. Further, it is likely that such a tsunami event would be occur
in the bayside areas of San Rafael, and the Project site is located approximately two miles inland.
Additionally, the San Rafael General Plan EIR, that the San Rafael area has a moderate potential for
small flow failures and a low potential for large flow failures. The proposed Project would be
engineered and designed based on the Caltrans Seismic Design Criteria. As the Project includes the
replacement of an existing bridge, and would not place residential or other sensitive land uses in
hazard areas, impacts associated with inundation by seiche, tsunami, or mudflow would be less than
significant.

Minerals are any naturally occurring chemical element or compound, or groups of elements and
compounds, formed from inorganic processes and organic substances including, but not limited to,
coal, peat and oil bearing rock, but excluding geothermal resources, natural gas and petroleum.
Rock, sand, gravel, and earth are also considered minerals by the California Department of
Conservation when extracted by surface mining operations. According to the San Rafael General
Plan EIR, the only mineral resource in the San Rafael Planning Area is the San Rafael Rock Quarry,
which is located over 3.5 miles to the northeast. No mines are located on or in the vicinity of the
Project site.
3.11.2 Impact Analysis
a. Would the project result in the loss of availability of a known mineral resource that would be of
value to the region and the residents of the state?
NO IMPACT. The proposed Project is not located in a Mineral Resource Area, nor is one located near

mineral resource that would be of value to the region and the residents of the state. No impact
would occur.
b. Would the project result in the loss of availability of a locally-important mineral resource
recovery site delineated on a local general plan, specific plan or other land use plan?
NO IMPACT. The San Rafael Rock Quarry, located over 3.5 miles northeast of the Project site, is the
only mineral resource located in the City with local, regional, or state significance. No mines are
located on or in the vicinity of the Project site. Implementation of the proposed Project would not
result in the loss of such locally-important mineral resources. No impact would occur.

3.12.1 Environmental Setting
A Noise Technical Memorandum was prepared for the Project in July 2017. The information for the
following section was based on this study.
3.12.1.1 Construction and Operational Noise
Noise is usually defined as unwanted sound. Noise consists of any sound that may produce
physiological or psychological damage and/or interfere with communication, work, rest, recreation,
or sleep. To the human ear, sound has two significant characteristics: pitch and loudness. A specific
pitch can be an annoyance, while loudness can affect our ability to hear. Pitch is the number of
complete vibrations or cycles per second of a wave, that results in the range of tone from high to
low. Loudness is the strength of a sound that describes a noisy or quiet environment, and it is
measured by the amplitude of the sound wave. Loudness is determined by the intensity of the
sound waves combined with the reception characteristics of the human ear. Sound intensity refers
to how hard the sound wave strikes an object, which in turn produces the sound’s effect. This
characteristic of sound can be precisely measured with instruments.
Several noise measurement scales are used to describe noise in a particular location. A decibel (dB)
is a unit of measurement that indicates the relative intensity of a sound. The 0 point on the dB scale
is based on the lowest sound level that the healthy, unimpaired human ear can detect. Changes of
3.0 dB or less are only perceptible in laboratory environments. Audible increases in noise levels

generally refer to a change of 3.0 dB or more, as this level has been found to be barely perceptible
to the human ear in outdoor environments. Sound levels in dB are calculated on a logarithmic basis.
An increase of 10 dB represents a 10-fold increase in acoustic energy, while 20 dB is 100 times more
intense, 30 dB is 1,000 times more intense. Each 10 dB increase in sound level is perceived as
approximately a doubling of loudness. Sound intensity is normally measured through the A-
weighted sound level (dBA). This scale gives greater weight to the frequencies of sound to which the
human ear is most sensitive.
Noise impacts can be described in three categories. The first is audible impacts, which refers to
increases in noise levels noticeable to humans. Audible increases in noise levels generally refer to a
change of 3.0 dB or greater, since this level has been found to be barely perceptible in exterior
environments. The second category, potentially audible, refers to a change in the noise level
between 1.0 and 3.0 dB. This range of noise levels has been found to be noticeable only in
laboratory environments. The last category is changes in noise level of less than 1.0 dB, which are
inaudible to the human ear. Only audible changes in existing ambient or background noise levels are
considered potentially significant.
As noise spreads from a source, it loses energy so that the further away the noise receiver is from
the noise source, the lower the perceived noise level would be. Geometric spreading causes the
sound level to attenuate or be reduced, resulting in a 6 dB reduction in the noise level for each
doubling of distance from a single point source of noise to the noise sensitive receptor of concern.
There are many ways to rate noise for various time periods, but an appropriate rating of ambient
noise affecting humans also accounts for the annoying effects of sound. Equivalent continuous
sound level (Leq) is the total sound energy of time-varying noise over a sample period. However, the
predominant rating scales for human communities in the State of California are the Leq and
community noise equivalent level (CNEL) or the day-night average level (Ldn) based on A-weighted
decibels (dBA). CNEL is the time-varying noise over a 24-hour period, with a 5 dBA weighting factor
applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation
hours) and a 10 dBA weighting factor applied to noise occurring from 10:00 p.m. to 7:00 a.m.
(defined as sleeping hours). Ldn is similar to the CNEL scale but without the adjustment for events
occurring during the evening hours. CNEL and Ldn are within 1 dBA of each other and are normally
exchangeable. The noise adjustments are added to the noise events occurring during the more
sensitive hours. Other noise rating scales of importance when assessing the annoyance factor
include the maximum noise level (Lmax), which is the highest exponential time-averaged sound level
that occurs during a stated time period. The noise environments discussed in this analysis are
specified in terms of maximum levels denoted by Lmax for short-term noise impacts. Lmax reflects
peak operating conditions and addresses the annoying aspects of intermittent noise.
The proposed Project is located in a residential area of the City of San Rafael along Southern Heights
Boulevard. The closest sensitive receptors are existing single-family residential units located along
the east and west side of Southern Heights Boulevard. Six sensitive receptors (closest to the Project
site) have been identified that would potentially be exposed to Project related short-term
construction noise impacts. Table 5 identifies the six closest sensitive receptors.

Notes:1 The estimated distance is measured from the single-family residential structure on the parcel to the closest point of
the Project footprint where construction activities are anticipated to occur.
The City of San Rafael has established noise standards in Chapter 8.13 of their Municipal Code
declaring that it is the policy of the City, in the exercise of its police power, to protect the peace,
health, safety, and general welfare of the citizens of San Rafael from excessive, unnecessary and
unreasonable noises from any and all sources in the community. Section 8.13.050 (A) Standard
exceptions to general noise limits, provides noise limits for construction as follows:
“Except as otherwise provided in Subsection B of this section, or by the planning
commission or city council as part of the development review for the project, on any
construction project or property within the city, construction, alteration,
demolition, maintenance of construction equipment, deliveries of materials or
equipment, or repair activities otherwise allowed under applicable law shall be
allowed between the hours of seven a.m. (7:00 a.m.) and six p.m. (6:00 p.m.),
Monday through Friday, and nine a.m. (9:00 a.m.) and six p.m. (6:00 p.m.) on
Saturdays, provided that the noise level at any point outside of the property plane
of the project shall not exceed ninety (90) dBA. All such activities shall be precluded
on Sundays and holidays. Violation of the foregoing may subject the permittee to
suspension of work by the chief building official for up to two (2) days per violation.”
The construction contractor of the proposed Project would be required to comply with Section
8.13.050 (A) of the San Rafael Noise Ordinance during construction activities.
The City of Rafael Ordinance 8.13.060 Exceptions Allowed with Permit, states “…the director of
community development or his designee may grant a permit allowing an exception from any or all
provisions of this chapter where the applicant can show that a diligent investigation of available
noise abatement techniques indicates that immediate compliance with the requirements of this
chapter would be impracticable or unreasonable, or that no public detriment will result from the
proposed exception…”

Groundborne Vibrations
Groundborne vibration can be a serious concern for residential areas and sensitive land uses;
including areas with underground aquifers and springs supplying water. Some common sources of
groundborne vibration include construction activities such as blasting, pile-driving, and operating
heavy earth-moving equipment. Vibration is an oscillatory motion which can be described in terms
of the displacement, velocity, or acceleration. The response of humans, buildings, sensitive land use
areas, and equipment vibration is more accurately described using velocity or acceleration. The Peak
Particle Velocity (PPV) is used to describe construction-related vibrations. The PPV is defined as the
maximum instantaneous positive or negative peak of the vibration signal and is measured in
inches/second. PPV is often used in monitoring of blasting vibration since it is related to the stresses
that are experienced by buildings. Table 6 provides typical vibration levels generated by operating
construction equipment as measured from 25 feet away.

The City of San Rafael does not regulate vibration impacts from construction activity and thresholds
are not discussed in the San Rafael General Plan or the City San Rafael Code of Ordinances. The
Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment 3 guidelines
indicate that a vibration level up to 102 VdB (an equivalent to 0.5 in/sec in PPV) is considered safe
for buildings consisting of reinforced concrete, steel, or timber (no plaster), and would not result in
any construction vibration damage. For a non-engineered timber and masonry building, the
construction vibration damage criterion is 94 VdB (0.2 in/sec in PPV).

3.12.2 Impact Analysis
a. Would the project result in exposure of persons to or generation of noise levels in excess of
standards established in the local general plan or noise ordinance, or applicable standards of
other agencies?
Construction Noise
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. Two types of short-term
noise impacts would occur during Project construction, including (1) equipment delivery and
construction worker commutes and (2) Project construction operations.
The first type of short-term construction noise would result from the transport of construction
equipment and materials to the Project site and from construction worker commutes. These
transportation activities would incrementally raise noise levels on roads leading to the Project site.
Larger trucks used in equipment delivery are expected to generate higher noise impacts than trucks
associated with worker commutes. The single-event noise from equipment trucks passing at a
distance of 50 feet from a sensitive noise receptor would reach a maximum level of 84 dBA Lmax.
However, the pieces of heavy equipment for grading and construction activities would be moved on
site just one time, and would remain for the duration of construction. This one-time trip, when
heavy construction equipment is moved on- and off-site, would not add to the daily traffic noise in
the Project vicinity. Furthermore, the projected traffic from the construction worker commutes
would be minimal when compared to existing traffic volumes on roadways near the Project and
other affected streets, and its associated long-term noise level change would not be perceptible.
Therefore, equipment delivery noise and construction-related worker commute impacts would be
short-term and would not be substantial.
The second type of short-term construction noise would be related to noise generated during
Project construction. Construction is performed in discrete steps, each having its own mix of
equipment and, consequently, its own noise characteristics. These various sequential phases will
change the character of the noise generated, as well as the noise levels in the study area as
construction progresses. Despite the variety in the type and size of construction equipment,
similarities in the dominant noise sources and patterns of operation allow construction-related
noise ranges to be categorized by work phase. Table 7 lists typical construction equipment noise
levels (Lmax) recommended for noise impact assessments based on a distance of 50 feet between the
equipment and a noise receptor.

1 Equipment shown in bold is expected to be used on site.
2 Maximum noise levels were developed based on Spec 721.560 from the Central Artery/Tunnel (CA/T) program to be consistent with the
City of Boston’s Noise Code for the “Big Dig” project.
Note: Noise levels reported in this table are rounded to the nearest whole number.
Lmax = maximum instantaneous sound level
Normal construction operations, specifically during the site preparation phase, which includes
excavation and grading, may generate high noise levels from an active construction area.
Earthmoving equipment includes excavating machinery (e.g., backfillers, bulldozers, and front-end
loaders). Earthmoving and compacting equipment includes compactors, scrapers, and graders.
Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of
full-power operation followed by 3 or 4 minutes at lower power settings.
Noise associated with the use of earthmoving construction equipment is estimated between 55 and
85 dBA Lmax at a distance of 50 feet from each piece of equipment. As seen in Table 7, the maximum
noise level generated by each excavator (with jack hammer attachment), bulldozer, crane, tractor,
auger drill rig and truck is assumed to be approximately 85 dBA Lmax, 85 dBA Lmax, 85 dBA Lmax, 84
dBA Lmax, 84 dBA Lmax and 55 dBA Lmax at 50 feet, respectively. Each piece of construction equipment
operates as an individual point source.
In general, doubling the distance would decrease noise levels by 6 dBA while a halving of the
distance would increase noise levels by 6 dBA.

During construction, it is assumed that each piece of construction equipment operates at some
distance from the other equipment. Table 8 shows the estimated Leq and maximum noise levels each
of the sensitive receptors are anticipated to be exposed to during construction activities.

Notes:1 The estimated distance is measured from the single-family residential structure on the parcel to the closest point of the Project
footprint where construction activities are anticipated to occur.
2 The Leq and Lmax noise levels are based on a worst case scenario where each of the pieces of construction equipment (excavator (with
jack hammer attachment), bulldozer, crane, tractor, auger drill rig, and truck) are operating simultaneously, in close proximity to each
other, at the closest point where construction would occur in comparison to the locations of the sensitive receptors.
Table 8 indicates that the sensitive receptors near the Project site could be exposed to equivalent
continuous sound levels ranging from 84 to 95 dBA Leq and maximum noise levels ranging from 86 to
97 dBA Lmax. Such noise levels would exceed the thresholds established by Caltrans and locally by the
City of San Rafael and therefore minimization measures would be needed to ensure compatibility
with these established noise thresholds. It should be noted that construction activities along the
western side of Southern Heights Boulevard (closest to the sensitive receptors) is anticipated to be
temporary as construction proceeds. Construction activities would continue within the Project site
gradually moving westward away from the sensitive receptors and down the slope thus providing
additional attenuation of noise levels that the sensitive receptors would be exposed to. Mitigation
Measure NOI-1 is recommended to reduce potentially significant impacts.
Mitigation Measure NOI-1: The proposed Project shall comply with the City of San
Rafael Code of Ordinances Section 8.13.050 by ensuring that construction activities
only occur between the hours of 7:00 AM and 6:00 PM Monday through Friday and
9:00 AM and 6:00 PM on Saturdays and that the noise level at any point outside of
the property plane of the project would not exceed 90 dBA.
Based on the analysis presented above, noise levels when multiple pieces of equipment would
operate simultaneously would exceed the City’s suggested maximum noise threshold of 90 dBA.
Therefore, per Section 8.13.06 of the City of San Rafael Noise Ordinance, the project contractor may
apply for a permit of exception through the City of San Rafael Director of Community Development
or his/her designee. If no permit is granted, Mitigation Measure NOI-2 is recommended for
implementation when construction activities occur within 100 feet of the western Project boundary:
Mitigation Measure NOI-2: The construction contractor shall permit only two pieces
of construction equipment to operate at any single time within 100 feet of the

western boundary of the Project site. This strategy would reduce the construction
noise level to meet the City’s construction noise standard of 90 dBA Lmax outside of
the property plane of the Project.
The construction contractor shall place all stationary construction equipment so
that emitted noise is directed away from boundaries of the Project site.
The construction contractor shall also locate equipment staging in areas that will
create the greatest possible distance between construction-related noise sources,
Project site boundaries, and noise-sensitive receptors nearest the Project site during
all Project construction.
The contractor shall ensure that all construction equipment is equipped with
manufacturers approved mufflers and baffles.
The City of San Rafael will continue public relations with residents near the proposed Project by
providing construction information pamphlets which describe the type of construction activities that
would occur, the duration of Project construction, indication that a temporary increase in ambient
noise levels could occur during Project construction, and a phone number where concerned
residents can call City Staff if noise levels from construction activities are exceeded during hours as
specified by the City’s Municipal Code. With implementation of Mitigation Measures NOI-1 and NOI-
2, construction impacts would be less than significant.
Operational Noise
LESS THAN SIGNIFICANT IMPACT. The proposed Project would replace the existing bridge with a
new structure accommodating one 12-foot wide lane and bridge railings, resulting in an
approximate bridge width of 15 feet and approximate length of 127 feet (a three-span reinforced
concrete slab bridge). Additionally, the Project would result in smooth pavement and a structurally
sound bridge that would ultimately reduce the noise levels experienced in the Project vicinity from
usage of the existing bridge. The bridge on Southern Heights Boulevard would remain a one-lane
road outside and inside of the Project boundary; therefore, it is not anticipated that vehicular trips
through the Project area would increase in the future. Operational impacts would be less than
significant.
b. Would the project result in exposure of persons to or generation of excessive groundborne
vibration or groundborne noise levels?
LESS THAN SIGNIFICANT IMPACT. Vibration refers to groundborne noise and perceptible motion.
Groundborne vibration is almost exclusively a concern inside buildings and is rarely perceived as a
problem outdoors. Vibration energy propagates from a source, through intervening soil and rock
layers, to the foundations of nearby buildings. The vibration then propagates from the foundation
throughout the remainder of the structure. Building vibration may be perceived by the occupants as
the motion of building surfaces, rattling of items on shelves or hanging on walls, or as a low-
frequency rumbling noise. The rumbling noise is caused by the vibrating walls, floors, and ceilings

radiating sound waves. Annoyance from vibration often occurs when the vibration exceeds the
threshold of perception by 10 dB or less. This is an order of magnitude below the damage threshold
for normal buildings.
Typical sources of groundborne vibration are construction activities (e.g., pavement breaking and
operating heavy-duty earthmoving equipment), and occasional traffic on rough roads. Groundborne
vibration levels from construction activities very rarely reach levels that can damage structures;
however, these levels are perceptible near the active construction site. With the exception of old
buildings built prior to the 1950s, or buildings of historic significance, potential structural damage
from heavy construction activities rarely occurs. When roadways are smooth, vibration from traffic
(even heavy trucks) is rarely perceptible.
Once constructed, the project pavement would be smooth, and unlikely to cause significant
groundborne vibration. In addition, the rubber tires and suspension systems of buses and other on-
road vehicles make it unusual for on-road vehicles to cause groundborne noise or vibration
problems. It is, therefore, assumed that no such vehicular vibration impacts would occur.
Construction Vibration
LESS THAN SIGNIFICANT IMPACT. The proposed Project construction boundary is located
approximately 25 feet from the closest sensitive receptors. This construction vibration impact
analysis discusses the level of human annoyance using vibration levels in VdB and will assess the
potential for building damages using vibration levels in PPV (in/sec) because vibration levels
calculated in RMS are best for characterizing human response to building vibration, while vibration
level in PPV is best used to characterize potential for damage. As discussed above, FTA guidelines
indicate that a vibration level up to 102 VdB (an equivalent to 0.5 in/sec in PPV) is considered safe
for buildings consisting of reinforced concrete, steel, or timber (no plaster), and would not result in
any construction vibration damage. For a non-engineered timber and masonry building, the
construction vibration damage criterion is 94 VdB (0.2 in/sec in PPV).
Table 6 shows the PPV and VdB values at 25 feet from a construction vibration source. As shown in
Table 6, bulldozers and other heavy-tracked construction equipment (except for pile drivers and
vibratory rollers) generate approximately 87 VdB of groundborne vibration when measured at 25
feet, based on the Transit Noise and Vibration Impact Assessment. At this level, groundborne
vibration would result in potential annoyance to residents and workers, but would not cause any
damage to the buildings. Construction vibration, similar to vibration from other sources, would not
have any significant effects on outdoor activities (e.g., those outside of residences and
commercial/office buildings in the project vicinity). Outdoor site preparation for the project is
expected to use a bulldozer, loaded truck and caisson drilling. The greatest levels of vibration are
anticipated to occur during the site preparation and drilling phase. All other phases are expected to
result in lower vibration levels. The distance to the nearest buildings for vibration impact analysis is
measured between the nearest off-site buildings and the project boundary (assuming the
construction equipment would be used at or near the Project boundary) because vibration impacts
occur normally within the buildings. The formula for vibration transmission is provided below.

LvdB (D) = LvdB (25 ft) – 30 Log (D/25)
PPVequip = PPVref x (25/D)1.5
For typical construction activity, the equipment with the highest vibration generation potential is
the large bulldozer or caisson drilling, which would each generate 87 VdB at 25 feet. The closest
residential structures are located 25 feet from the Project construction boundary. Therefore, the
closest residences would experience vibration levels of up to 87 VdB (0.089 PPV [in/sec]). This
vibration level at the closest residential structures from construction equipment would not exceed
the FTA threshold of 94 VdB (0.2 in/sec PPV) for building damage. Therefore, groundborne vibration
impacts from Project-related construction activities would be considered less than significant.
c. Would the project result in a substantial permanent increase in ambient noise levels in the
project vicinity above levels existing without the project?
NO IMPACT. The proposed Project would replace the existing bridge with a new structure
accommodating one 12-foot wide lane and bridge railings, resulting in an approximate bridge width
of 15 feet and approximate length of 127 feet (a three-span reinforced concrete slab bridge).
Additionally, the Project would result in smooth pavement and a structurally sound bridge that
would ultimately reduce the noise levels experienced in the Project vicinity from usage of the
existing bridge. The bridge on Southern Heights Boulevard would remain a one-lane road outside
and inside of the Project boundary; therefore, it is not anticipated that vehicular trips through the
Project area would increase in the future. Therefore, the proposed Project would not result in a
substantial permanent increase in ambient noise levels in the Project vicinity. No impact would
occur.
d. Would the project result in a substantial temporary or periodic increase in ambient noise levels in
the project vicinity above levels existing without the project?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. As discussed under Question
A, construction of the proposed Project would result in an increase to ambient noise levels in the
Project vicinity above levels existing without the Project. Mitigation Measures NOI-1 and NOI-2
would reduce potential impacts associated with construction noise. With implementation of
mitigation measures, temporary increases in ambient noise levels in the Project vicinity during
construction would be less than significant.
e. For a project located within an airport land use plan or, where such a plan has not been adopted,
within 2 miles of a public airport or public use airport, would the project expose people residing
or working in the project area to excessive noise levels?
NO IMPACT. The nearest public airport is Gnoss Field Airport, located over 12 miles north of the
Project site. The Project site is not located within an airport land use plan or within 2 miles of a
public airport or public use airport. No impact would occur.

(U.S. Census Bureau 2016a). Data from the 2012-2016 American Community Survey 5-Year
Estimates report that Census Tract 1121 had a total population of 5,114 people in housing units, of
which 2,493 people lived in owner occupied units and 2,621 people lived in renter occupied units
(U.S. Census Bureau 2016b).
3.13.2 Impact Analysis

population growth in the San Rafael area as it does not include the development of new homes or
businesses. The Project would not increase the number of lanes along the bridge. Therefore, the
proposed Project would not indirectly induce substantial population growth in the Project area.
Impacts would be less than significant.
b. Would the project displace substantial numbers of existing housing, necessitating the
construction of replacement housing elsewhere?

The San Rafael Fire Department provides emergency services for the City of San Rafael and the
Project area, though the Marin County Fire Department can also provide fire services to the San
Rafael area because of joint powers agreements and standard mutual aid agreements that are in
place to minimize response times in fire emergencies. The San Rafael Fire Department is an
organization with 90 professionals trained in specialties including emergency medical care,
firefighting, hazardous materials, and emergency preparedness. The closest station to the Project
site is Fire Station 51, located 1039 C Street in San Rafael. Fire Station 1 is located about 0.8 mile
north of the Project site. The Fire Department currently operates a Type I Engine, an Ambulance, an
Air Unit, and an Office of Emergency Services Type 1 Engine.
3.14.1.2 Law Enforcement
The City of San Rafael Police Department provides law enforcement services to the City of San
Rafael. The Department headquarters are located at 1400 Fifth Avenue, about 0.84 miles north of
the Project site. The Department has an officer-to-resident service-standard ratio of 1.4 officers per
1,000 residents. There are 66 sworn police officers in the City of San Rafael Police Department.
3.14.1.3 School
Three school districts provide educational services in the City of San Rafael: Dixie Elementary School
District, San Rafael City Elementary School District, and San Rafael High School District. Seventeen
schools within these 3 school districts serve the community of San Rafael.

3.16.1 Environmental Setting
The proposed Project is located along Southern Heights Boulevard, a narrow one-lane roadway that
provides local access to residential properties throughout the neighborhood. The existing bridge
consists of a 162-foot long, multi-span, timber structure. The existing bridge was closed on
December 28, 2017 due to severe deterioration.
The Project site is not located near any major intersections. As stated above, the roadway contains
only one lane and provides local access to residential properties, so daily traffic is primarily limited
to residents and visitors to the neighborhood.
The Project site is not located on an existing or proposed non-motorized transportation route
(bicycle), bus transit service system route, or designated/eligible scenic roadway segment.

3.16.2 Impact Analysis
a. Would the project conflict with an applicable plan, ordinance or policy establishing measures of
effectiveness for the performance of the circulation system, taking into account all modes of
transportation including mass transit and non-motorized travel and relevant components of the
circulation system, including but not limited to intersections, streets, highways and freeways,
pedestrian and bicycle paths, and mass transit?
LESS THAN SIGNIFICANT IMPACT. A small volume of traffic would be generated during construction
of the proposed Project due to the increase in vehicle trips associated with construction equipment
and trucks. However, the number of vehicles would be minimal (e.g., staging construction
equipment at the Project site would eliminate vehicle trips during construction) and the
demolition/construction period would be of a temporary duration (approximately six months).
During construction, Southern Heights Bridge would continue to be closed to traffic; however,
access would remain open for residents along the bridge. Prior to the bridge closure, average daily
traffic along Southern Heights Boulevard was 150 vehicles per day. The closure has redirected traffic
to other local roads. Therefore, no additional delays in traffic would occur during demolition and
construction of the proposed Project. Construction-related impacts to traffic and circulation along
Southern Heights Boulevard would be less than significant.
Once completed the proposed Project would not generate an increase in traffic volumes along
Southern Heights Boulevard as the proposed bridge would restore one lane access for motorists.
Furthermore, the proposed Project is not near any major intersections and would not impact local
intersection traffic volumes. Operational-related impacts to traffic and circulation along Southern
Heights Boulevard would be less than significant.
b. Would the project conflict with an applicable congestion management program, including, but
not limited to level of service standards and travel demand measures, or other standards
established by the county congestion management agency for designated roads or highways?
LESS THAN SIGNIFICANT IMPACT. Construction activities associated with the proposed Project
would generate only a small increase in vehicular traffic associated with construction
equipment/trucks and personnel traveling to and from the Project site. However, the increase in
traffic would be minimal during construction activities. Once completed, the proposed Project
would not generate an increase in the traffic volume along Southern Heights Boulevard as the
Project is a bridge replacement project and is not traffic-inducing or capacity-increasing. Therefore,
the Project would not conflict with an applicable congestion management program and impacts
would be less than significant.
c. Would the project result in a change in air traffic patterns, including either an increase in traffic
levels or a change in location which results in substantial safety risks?
NO IMPACT. The proposed Project does not include any towers or any tall structures that would
result in a change in air traffic patterns, including either an increase in air traffic levels or change in
location that would result in substantial air safety risks. No impact would occur.

d. Would the project substantially increase hazards due to a design feature (e.g., sharp curves or
dangerous intersections) or incompatible uses (e.g., farm equipment)?
NO IMPACT. Development of the proposed Project would use updated design features that would
reduce hazards for vehicles and pedestrians traveling along Southern Heights Boulevard. The
proposed Project would not be incompatible with surrounding uses. The proposed Project would
not substantially increase hazards due to design feature or incompatible uses. No impact would
occur.
e. Would the project result in inadequate emergency access?
LESS THAN SIGNIFICANT IMPACT. The proposed Project is located on Southern Heights Boulevard, a
local roadway in a low-density/hillside residential area of San Rafael. The existing bridge does not
allow for emergency service vehicles as it is too narrow; this situation would remain unchanged
during Project construction.
During operation, access to the local roadway network would be improved compared to existing
conditions. The bridge structure would be widened to allow access for emergency service vehicles.
Impacts to emergency access would be less than significant.
f. Would the project conflict with adopted policies, plans or programs regarding public transit,
bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such
facilities?
NO IMPACT. Southern Heights Boulevard is not located on an existing or proposed non-motorized
transportation route or bus transit service system route, though the roadway is utilized as a
pedestrian route for local residents along the roadway. The proposed Project would enhance the
safety of the roadway as the bridge would be widened. No impact would occur.

Would the project:
a. Cause a substantial adverse change in the significance of a
tribal cultural resource, defined in Public Resources Code
Section 21074 as either a site, feature, place, cultural
landscape that is geographically defined in terms of the size
and scope of the landscape, sacred place, or object with
cultural value to a California Native American tribe, and that
is:
i. Listed or eligible for listing in the California Register of
Historical Resources, or in a local register of historical
resources as defined in Public Resources Code Section
5020.1(k)? Or
ii. A resource determined by the lead agency, in its
discretion and supported by substantial evidence, to be
significant pursuant to criteria set forth in subdivision
(c) of Public Resources Code Section 5024.1? In applying
the criteria set forth in subdivision (c) of Public
Resource Code Section 5024.1, the lead agency shall
consider the significance of the resource to a California
Native American tribe.
3.17.1 Environmental Setting
Assembly Bill (AB) 52, a new state law recently (2014) signed by the governor, amended the
California Environmental Quality Act (CEQA) to require Tribal Cultural Resources to be considered as
potentially significant cultural resources under the CEQA environmental review process. The new
procedures under AB 52 offer the tribes an opportunity to take an active role in the CEQA process in
order to protect tribal cultural resources.
Letters requesting consultation pursuant to AB 52 were sent to two FIGR representatives on April
19, 2017. Buffy McQuillen, the Tribal Heritage Preservation Officer (THPO) for FIGR responded on
May 10, 2017, stating that the Tribe would review the project within 10 business days. In a
subsequent email on May 22, 2017, Ms. McQuillen stated that “the project is likely to impact tribal
cultural resources important to the Tribe, with additional concern that human remains may be
nearby. The Tribe would like to participate in the survey phase if it has not been completed at this
time.” Sally Evans of Evans & De Shazo, LLC responded to Ms. McQuillen on May 24, 2017, stating
that the field survey had already been conducted for the project, but provided a copy of the draft
Archaeological Survey Report (ASR) for the Tribe to review, noting that she would incorporate the
comments regarding the Tribe’s concerns that human remains may be nearby into the report. Ms.
Evans also offered to arrange a field visit should the Tribe be interested in visiting the site. No
response was received from Ms. McQuillen or another representative. Ms. Evans followed up with
Ms. McQuillen on September 21, 2017 via email to ask if the ASR had been reviewed and offered
continuing consultation regarding the Tribe’s concern that tribal cultural resources could be

impacted by the Project. On October 2, 2017, Ms. Evans followed up with Ms. McQuillen via email
and again provided the draft ASR, and requested a day and time for a phone call to ensure the
Tribe’s concerns are fully addressed. No response has been received from Ms. McQuillen to date. As
no response has been received, the City considers consultation with FIGR pursuant to Public
Resource Code section 21080.3.1 complete.
3.17.2 Impact Analysis
a. Would the project cause a substantial adverse change in the significance of a tribal cultural
resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural
landscape that is geographically defined in terms of the size and scope of the landscape, sacred
place, or object with cultural value to a California Native American tribe, and that is:
i. Listed or eligible for listing in the California Register of Historical Resources, or in a local
register of historical resources as defined in Public Resources Code Section 5020.1(k)? Or
ii. A resource determined by the lead agency, in its discretion and supported by substantial

Code Section 5024.1? In applying the criteria set forth in subdivision (c) of Public Resource
Code Section 5024.1, the lead agency shall consider the significance of the resource to a
California Native American tribe.
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. FIGR did not identify specific
tribal cultural resources; however, they stated that the Project site is likely to impact tribal cultural
resources that are important to the Tribe, with additional concern that human remains may be
nearby. No additional information or responses were provided by FIGR. As described above,
research was conducted to determine if sensitive historical or Native American sites were located
within the APE or surrounding the Project site. No tribal cultural resources were identified within or
adjacent to the APE that are listed or eligible for listing in the CRHR, in a local register of historical
resources as defined in Public Resources Code (PRC) Section 5020.1(k), or have been determined by
the City of San Rafael to be significant pursuant to PRC Section 5024.1.
Implementation of Mitigation Measures CULT-1 and CULT-2, as presented in the Cultural Resources
section above, would reduce any potentially significant impacts from the proposed Project to tribal
cultural resources, including human remains, which may be inadvertently discovered during
construction activities, to a less than significant level.

Impact
Would the project:
a. Exceed wastewater treatment requirements of the
applicable Regional Water Quality Control Board?
b. Require or result in the construction of new water or
wastewater treatment facilities or expansion of existing
facilities, the construction of which could cause significant
environmental effects?
c. Require or result in the construction of new storm water
drainage facilities or expansion of existing facilities, the
construction of which could cause significant environmental
effects?
d. Have sufficient water supplies available to serve the project
from existing entitlements and resources, or are new or
expanded entitlements needed?
e. Result in a determination by the wastewater treatment
provider which serves or may serve the project that it has
adequate capacity to serve the project’s projected demand
in addition to the provider’s existing commitments?
f. Be served by a landfill with sufficient permitted capacity to
accommodate the project’s solid waste disposal needs?
g. Comply with federal, state, and local statutes and
regulations related to solid waste?
3.18.1 Environmental Setting
The Project site is located in a low-density/hillside residential area of San Rafael where utilities are
available. San Rafael is within the jurisdiction of the San Francisco Regional Water Quality Control
Board – Region 2 (SFRWQCB).
3.18.1.1 Water
San Rafael is supplied water by the Marin Municipal Water District (MMWD), a public utility
governed by an elected board. The primary water source for the MMWD is rainfall stored in two
area reservoirs. MMWD facilities include six area reservoirs, two water treatment plants, storage
tanks, pumps, and lines (City of San Rafael 2004).
3.18.1.2 Wastewater
The San Rafael Sanitation District provides sanitary collection and wastewater treatment to the
Project area. The San Rafael Sanitation District is one of the three member service districts that
comprise the Central Marin Sanitation Agency (CMSA). Wastewater from all three districts flows to
the CMSA plant, which is located in San Rafael (City of San Rafael 2004).

3.18.1.3 Solid Waste
The Marin Sanitary Service oversees solid waste disposal and recycling services in the Project area.
Solid waste collection is provided through commercial collectors. Marin Sanitary Service operates a
transfer station where waste from commercial collectors is taken and then hauled by transfer truck
to Redwood Landfill (City of San Rafael 2004). The landfill is permitted to accept a capacity of 2,300
tons of waste per day. The estimated closure date for this landfill is July 1, 2024 (CalRecycle 2018).
3.18.1.4 Power
Pacific Gas and Electric (PG&E) is the electricity service purveyor in the City of San Rafael. Overhead
power and communication are located within the Project site.
3.18.2 Impact Analysis
a. Would the project exceed wastewater treatment requirements of the applicable Regional Water
Quality Control Board?
NO IMPACT. The proposed Project would replace the existing bridge along Southern Heights
Boulevard with a new structure. No components of the proposed construction would generate
wastewater or an increased demand for wastewater treatment. Therefore, the Project would not
exceed the wastewater treatment requirements of the SFRWQCB, and no impact would occur.
b. Would the project require or result in the construction of new water or wastewater treatment
facilities or expansion of existing facilities, the construction of which could cause significant
environmental effects?
LESS THAN SIGNIFICANT IMPACT. During construction activities at the Project site, water associated
with dust controlling activities would be expected to be used in minimal amounts. The water that
would be used during construction would be provided by the contractor. The contractor may
coordinate directly with MMWD to obtain a meter that can be connected to a fire hydrant at the
site. Any wastewater that is generated at the Project site during construction would be hauled off-
site for processing.
The proposed Project would require water and would generate wastewater only during
construction. The amount of water required and wastewater anticipated to be generated during
construction would be minimal and would occur on a temporary basis for the duration of
construction activities. No new water treatment or wastewater treatment facilities would have to be
provided in association with construction of the proposed Project. Operation of the proposed
Project would not result in any new residences or businesses, and would therefore not impact
wastewater treatment. Impacts would be less than significant.

c. Would the project require or result in the construction of new storm water drainage facilities or
expansion of existing facilities, the construction of which could cause significant environmental
effects?
LESS THAN SIGNIFICANT IMPACT. Runoff from Southern Heights Boulevard currently collects at and
flows through a culvert downslope into an adjoining neighborhood. The proposed Project would not
substantially increase the bridge footprint and existing drainage facilities are anticipated to be
sufficient for the Project. Therefore, no new or expanded stormwater drainage facilities would be
required and impacts would be less than significant.
d. Would the project have sufficient water supplies available to serve the project from existing
entitlements and resources, or are new or expanded entitlements needed?
LESS THAN SIGNIFICANT IMPACT. Water demand for dust control operations would be minimal. It is
anticipated that MMWD has sufficient water supplies to serve the Project. No further water supplies
would be required to serve the proposed Project, and operation would not require water service. As
such, no impacts would occur.
e. Would the project result in a determination by the wastewater treatment provider which serves
or may serve the project that it has adequate capacity to serve the project’s projected demand in
addition to the provider’s existing commitments?
NO IMPACT. During construction of the proposed Project, workers on-site would generate a
nominal amount of wastewater. Any amount of wastewater generated by construction workers
would be hauled and treated off-site. No impacts would occur to wastewater treatment
requirements, nor would new wastewater facilities or sewage systems need to be constructed.
Operations would have no impact on wastewater. The Project would have no impact.
f. Would the project be served by a landfill with sufficient permitted capacity to accommodate the
project’s solid waste disposal needs?
LESS THAN SIGNIFICANT IMPACT. The proposed Project would temporarily generate construction
and demolition debris as the existing bridge is demolished and the new bridge is constructed.
Construction-related solid waste generated by the proposed Project would include wood and
concrete debris, inert materials, and mixed municipal solid waste from construction workers on the
Project site. Once operational, the proposed Project would not generate solid waste. The amount of
solid waste that would be generated during construction of the proposed Project would be minimal
compared to the existing daily intake at the Redwood Landfill. The landfill would be able to intake
material from the Project site during the temporary construction period and would still have
remaining daily intake capacity to serve other solid waste disposal requirements. Considering that
solid waste would be generated during construction only and no solid waste would be generated
during the operation of the Project, disposal operations at Redwood Landfill would not be impacted
by the proposed Project. Therefore, impacts would be less than significant.

3.19.1 Impact Analysis
a. Does the project have the potential to degrade the quality of the environment, substantially
reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below
self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce
the number or restrict the range of a rare or endangered plant or animal or eliminate important
examples of the major periods of California history or prehistory?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. The proposed Project would
include the replacement of an existing bridge along Southern Heights Boulevard. As described in this
Initial Study, implementation of the proposed Project would have the potential to adversely impact
migratory birds and previously undiscovered cultural resources and/or human remains. With
implementation of the mitigation measures recommended in this Initial Study, compliance with City
of San Rafael requirements, and application of standard practices, development of the proposed
Project would not: 1) degrade the quality of the environment; 2) substantially reduce the habitat of
fish or wildlife species; 3) cause a fish or wildlife population to drop below self-sustaining levels; 4)
threaten to eliminate a plant or animal community; 5) reduce the number or restrict the range of a
rare or endangered plant or animal; or, 6) eliminate important examples of the major periods of
California history or prehistory.

("Cumulatively considerable" means that the incremental effects of a project are considerable
when viewed in connection with the effects of past projects, the effects of other current projects,
and the effects of probable future projects)?
LESS THAN SIGNIFICANT IMPACT. The impacts of the proposed Project would be individually limited
and would not be cumulatively considerable. The proposed Project would include the replacement
of an existing bridge along Southern Heights Boulevard. All environmental impacts that could occur
as a result of the proposed Project would be reduced to a less than significant level with
implementation of the mitigation measures recommended throughout this Initial Study. When
viewed in conjunction with other closely-related past, present or reasonably foreseeable future
projects, development of this Project would not cumulatively contribute to impacts.
c. Does the project have environmental effects which will cause substantial adverse effects on
human beings, either directly or indirectly?
LESS THAN SIGNIFICANT IMPACT WITH MITIGATION INCORPORATED. The purpose of the proposed
Project is to replace the structurally-deficient bridge and to widen the bridge structure to improve
safety and provide access for emergency response vehicles. As described in this Initial Study,
implementation of the proposed Project could result in temporary aesthetic, air quality, geology and
soils, hazardous waste, hydrology, noise, and transportation and traffic impacts during the
construction period. Implementation of the mitigation measures recommended in this Initial Study,
compliance with City of San Rafael regulations, and application of standard construction practices
would ensure that the proposed Project would not result in environmental impacts that would
cause substantial direct or indirect adverse impacts on human beings.

MITIGATION MONITORING AND REPORTING PROGRAM
SOUTHERN HEIGHTS BRIDGE REPLACEMENT PROJECT
This Mitigation and Monitoring Reporting Program (MMRP) has been formulated based upon the findings of the Initial Study/Mitigated
Negative Declaration (IS/MND) prepared for the proposed Southern Heights Bridge Replacement Project (proposed project). The
purpose of the MMRP is to ensure the implementation of mitigation measures identified as part of the environmental review for the
project. The MMRP includes the following information:
•A list of mitigation measures;
•The party responsible for implementing the mitigation measures;
•The timing for implementation of the mitigation measure;
•The agency/city department responsible for monitoring the implementation; and
•The monitoring action and frequency.
The City of San Rafael must adopt this MMRP, or an equally effective program, if it approves the Southern Heights Bridge Replacement
Project with the mitigation measures that were adopted or made conditions of project approval.

Summary
The City of San Rafael (City), in conjunction with the California Department of
Transportation (Caltrans), is proposing to design and construct a new bridge on
Southern Heights Boulevard, located in eastern Marin County just south of central San
Rafael. The project site is located just north of the intersection of Meyer Road and
Southern Heights Boulevard in the Southern Heights neighborhood of San Rafael
(Figures 1–3).
The purpose of this Project is to increase driver safety and maintain neighborhood
access. The existing bridge has been given a sufficiency rating of 32.0 and a status of
structurally deficient due to its reduced load carrying capacity. The bridge width does not
meet current American Association of State Highway and Transportation Officials
(AASHTO) standards due to its narrow width, and the wooden bridge railings and lack of
approach guardrail is substandard.
The Biological Study Area (BSA), totaling 0.36 acres (ac), extends along Southern
Heights Boulevard for approximately 315 feet (ft) and includes areas 10 ft east and 20 ft
west of the roadway to accommodate temporary construction access.
The BSA is heavily disturbed and consists almost entirely of residential development,
landscaping, and ruderal/disturbed areas. One natural community, California Bay Forest,
occurs west of the existing bridge. Land uses in the immediate vicinity consist entirely of
residential development and landscaping.
The BSA does not contain suitable habitat for any special status species, including
federally listed species and critical habitat. Consequently, the project will not affect any
special status plant or wildlife species, and consultation pursuant to Section 7 of the
Federal Endangered Species Act (FESA) will not be required. There are no aquatic
features in the BSA; consequently, the project will not affect jurisdictional waters and
regulatory permits will not be required.

Chapter 1 – Introduction
The City, in conjunction with Caltrans, is proposing to design and construct a new bridge
on Southern Heights Boulevard, located in eastern Marin County just south of central
San Rafael. The Southern Heights Boulevard Bridge is located just north of the
intersection of Meyer Road and Southern Heights Boulevard in the Southern Heights
neighborhood of San Rafael (Figures 1–3).
1.1 Project History
The existing Southern Heights Bridge was constructed in 1958 and reconstructed in
1981. It is a narrow one-lane roadway that provides local access to residential properties
throughout the neighborhood. The hillside crossing consists of a 162-ft, multi-span
timber structure.
1.1.1 PURPOSE AND NEED
The purpose of this Project is to increase driver safety and maintain neighborhood
access. The existing bridge (Bridge No. 27C0148) has been given a sufficiency rating of
32.0 and a status of structurally deficient due to its reduced load carrying capacity. The
bridge width does not meet current AASHTO standards due to its narrow width, and the
wooden bridge railings and lack of approach guardrail is substandard.
1.2 Project Description
The proposed project will replace the existing bridge with a new structure
accommodating one 12-ft wide lane and bridge railings, resulting in an approximate
bridge width of 15 ft. The new bridge type has not been determined, but the structure is
expected to be a 100-ft long, multi-span concrete or steel bridge.
The roadway alignment and grade will remain unchanged. The southern roadway
approach and retaining wall will begin approximately 20 ft south of the existing southern
bridge abutment. The new southern bridge abutment will be shifted north of the driveway
to 116 Southern Heights. The northern roadway approach will begin 45 ft north of the
existing northern bridge abutment. The new northern bridge abutment will be shifted
south of the walking access path to 122 Southern Heights. A 115-ft long retaining wall
will be constructed to the west of the existing retaining wall to allow for the widened
bridge. The new retaining wall is expected to be a solider pile wall with steel H-piles and
timber lagging with a concrete structural section on the outside face.

The existing right-of-way width is 20 ft. No new right-of-way will be required for the new
bridge or retaining walls. Temporary construction easements are anticipated on the east
and west sides of the bridge to provide construction access. Utilities, including overhead
power and communication and underground water and natural gas, have been identified
and will need to be relocated with the project. It is not yet clear if the overhead utility
relocations can be accommodated within the existing right-of-way or if utility easements
will be needed for the utility poles and wires. The water and gas lines will be relocated
onto the new bridge.
Construction of the bridge will involve excavation for and construction of concrete
abutments and piers. The structure will be supported on cast-in-drilled-hole piles. There
is no waterway beneath the bridge but a corrugated metal storm drain pipe will need to
be temporarily relocated away from the structure during the excavation. Construction of
the roadway approaches will involve the removal of existing pavement, retaining walls,
fences, and the placement of fill material, aggregate base, hot mix asphalt pavement,
soldier pile and concrete retaining walls, and new guard rails. Tree removal and removal
of other vegetation along the slopes adjacent to the bridge will be necessary for the
project.
During construction, Southern Heights Boulevard will be closed to traffic and a detour
route will be provided. Construction is anticipated to begin in spring 2019 and will have a
duration of approximately 6 months.
The project design plans are included in Appendix A.

Chapter 2 – Study Methods
2.1 Regulatory Requirements
2.1.1 SPECIAL STATUS SPECIES
Special status species include plants and animals that are: 1) listed as rare, threatened,
or endangered by United States Fish and Wildlife Service (USFWS) or California
Department of Fish and Wildlife (CDFW ) under State or federal endangered species
acts; 2) are on formal lists as candidates for listing as threatened or endangered; 3) are
on formal lists as species of concern; or 4) are otherwise recognized at the State,
federal, or local level as sensitive.
2.1.1.1 Federal and California Endangered Species Acts
Under the FESA, it is unlawful to “take any species listed as threatened or endangered”.
“Take” is defined as to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or
collect, or attempt to engage in any such conduct.” An activity is defined as “take” even if
it is unintentional or accidental. Take provisions under FESA apply only to listed fish and
wildlife species under the jurisdiction of the USFWS and/or the National Oceanic &
Atmospheric Administration, National Marine Fisheries Service (NMFS). Consultation
with USFWS or NMFS is required if a project “may affect” a listed species.
When a species is listed, USFWS and/or NMFS, in most cases, must officially designate
specific areas as critical habitat for the species. Consultation with USFWS and/or NMFS
is required for projects that include a federal action or federal funding if the project may
affect designated critical habitat.
Under the California Endangered Species Act (CESA), it is unlawful to “take” any
species listed as rare, threatened, or endangered. Under CESA, “take” means to “hunt,
pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill”. CESA
take provisions apply to fish, wildlife, and plant species. Take may result whenever
activities occur in areas that support a listed species. Consultation with CDFW is
required if a project will result in “take” of a listed species.
2.1.1.2 Magnuson-Stevens Fishery Conservation and Management Act
Under the Magnuson-Stevens Fishery Conservation and Management Act (MSA),
essential fish habitat (EFH) must be designated in every fishery management plan.
EFH includes “…those waters and substrate necessary to fish for spawning, breeding,
feeding, or growth to maturity.” The MSA requires consultation with NMFS for projects
that include a federal action or federal funding and may adversely modify EFH.
-------------------------------------------------------------------------------------------------------------------------------------------------------■
NES 11
2.1.2 WATERS OF THE UNITED STATES AND OTHER JURISDICTIONAL
WATERS
2.1.2.1 Army Corps of Engineers
Under Section 404 of the Clean Water Act (CWA), the Army Corps of Engineers (ACOE)
regulates the discharge of dredged or fill material into waters of the United States (U.S.).
Waters of the U.S. are those waters that have a connection to interstate commerce,
either direct via a tributary system or indirect through a nexus identified in the ACOE
regulations. In non-tidal waters, the lateral limit of jurisdiction under Section 404 extends
to the ordinary high water mark (OHWM) of a waterbody or, where adjacent wetlands
are present, beyond the OHWM to the limit of the wetlands. The OHWM is defined as
“that line on the shore established by the fluctuations of water and indicated by physical
characteristics such as a clear natural line impressed on the bank, shelving, changes in
the character of the soil, destruction of terrestrial vegetation, the presence of litter and
debris, or other appropriate means that consider the characteristics of the surrounding
area” (33 Code of Federal Regulations 328.3). In tidal waters, the lateral limit of
jurisdiction extends to the high tide line or, where adjacent wetlands are present, to the
limit of the wetlands.
Wetlands
Wetlands are defined as “those areas that are inundated or saturated by surface or
ground water at a frequency and duration sufficient to support, and that under normal
circumstances do support, a prevalence of vegetation typically adapted for a life in
saturated soil conditions”.
Non-wetland Waters
Non-wetland waters essentially include any body of water, not otherwise exempted, that
displays an OHWM.
2.1.2.2 Regional Water Quality Control Board
Under Section 401 of the CWA, the State Water Resources Control Board must certify
all activities requiring a 404 permit. The Regional Water Quality Control Board (RWQCB)

2.1.2.3 California Department of Fish and Wildlife
CDFW, through provisions of Section 1602 of the California Fish and Game Code
(CFGC), is empowered to issue agreements for any alteration of a river, stream, or lake
where fish or wildlife resources may be substantially adversely affected. Streams (and
rivers) are defined by the presence of a channel bed and banks, and at least an
ephemeral or intermittent flow of water. CDFW regulates wetland areas only to the
extent that those wetlands are part of a river, stream, or lake as defined by CDFW.
CDFW generally includes, within the jurisdictional limits of streams and lakes, any
riparian habitat present. Riparian habitat includes willows, cottonwoods, and other
vegetation typically associated with the banks of a stream or lake shoreline. In most
situations, wetlands associated with a stream or lake would fall within the limits of
riparian habitat. Thus, defining the limits of CDFW jurisdiction based on riparian habitat
will automatically include any wetland areas. Riparian communities may not fall under
ACOE jurisdiction unless they are below the OHWM or classified as wetlands.
2.1.2.4 Executive Order 11990: Protection of Wetlands
Executive Order (EO) 11990 mandates leadership on the part of federal agencies to
reduce loss and degradation of wetlands and to preserve and enhance the beneficial
values and functions of wetlands. Each federal agency “shall avoid undertaking or
providing assistance for new construction located in wetlands unless the head of the
agency finds that: (1) there is no practicable alternative to such construction, and (2) that
the proposed action includes all practicable measures to minimize harm to wetlands
which may result from such use”.
2.1.3 MIGRATORY BIRD TREATY ACT
The Migratory Bird Treaty Act (MBTA) prohibits actions that will result in “take” of
migratory birds, their eggs, feathers, or nests. “Take” is defined in the MBTA as any
means or any manner to hunt, pursue, wound, kill, possess, or transport, any migratory
bird, nest, egg, or part thereof.
Migratory birds are also protected, as defined in the MBTA, under Section 3513 of the
CFGC.
2.1.4 CALIFORNIA FISH AND GAME CODE (BREEDING BIRDS)
Section 3503 of the CFGC prohibits the take, possession, or needless destruction of the
nest or eggs of any bird, except as otherwise provided by the CFGC or other regulation.

2.1.5 EXECUTIVE ORDER 13112: INVASIVE SPECIES
Under EO 13112, an invasive species is defined as “an alien species (a species not
native to a particular ecosystem) whose introduction does or is likely to cause economic
and environmental harm or harm to human health”. Invasive species are determined by
the Invasive Species Council.
In addition to other mandates, EO 13112 mandates federal agencies whose actions may
affect the status of invasive species to “not authorize, fund, or carry out actions that it
believes are likely to cause or promote the introduction or spread of invasive species”.
2.1.6 EXECUTIVE ORDER 11988: FLOODPLAIN MANAGEMENT
EO 11989 mandates leadership on the part of federal agencies to minimize the adverse
impacts associated with the occupancy and modification of floodplains and to avoid
direct and indirect support of floodplain development wherever there is a practicable
alternative.
Each agency shall provide leadership and shall take action to reduce the risk of flood
loss, to minimize the impact of floods on human safety, health and welfare, and to
restore and preserve the natural and beneficial values served by floodplains in carrying
out its responsibilities for (1) acquiring, managing, and disposing of federal lands, and
facilities; (2) providing federally undertaken, financed, or assisted construction and
improvements; and (3) conducting federal activities and programs affecting land use,
including, but not limited to, water and related land resources planning, regulating, and
licensing activities.
2.1.7 CITY OF SAN RAFAEL TREE ORDINANCE (CODE OF ORDINANCES
CHAPTER 11.12)
The City of San Rafael Tree Ordinance (Code of Ordinances Chapter 11.12) states:
• In the erection or repair of any building or structure, the owner thereof, or the
contractor, if the work is being done by contract, shall place such guards around
all nearby trees in, upon or along the public streets, sidewalks and walkways
within the city as shall prevent injury to them. (11.12.060)
• The provisions of Sections 11.12.030 to 11.12.080, inclusive, shall not be
applicable to any employee of the city who is acting within the scope of his
employment by the city. (11.12.085)

2.2 Studies Required
Prior to conducting any field studies, the limits of the BSA were established, totaling
approximately 0.36 ac, including portions of Southern Heights Boulevard and adjacent
lands both east and west of the bridge. The BSA consists of the project footprint,
temporary access areas, and lands beyond the edge of the road right-of-way that could
potentially be affected by project construction and/or were determined necessary to
inventory in order to perform an adequate analysis of project impacts.
The studies required to fully document the environmental conditions of the BSA included
a general biological survey, habitat mapping, and tree inventory.
2.2.1 LITERATURE REVIEW
A list of sensitive wildlife and plant species potentially occurring within the BSA and
vicinity was compiled to evaluate potential impacts resulting from project construction.
Sources used to compile the list include the California Natural Diversity Data Base
(CNDDB 2017), the USFWS Information for Planning and Conservation Trust Resources
(USFWS 2017), the California Native Plant Society (CNPS 2017) Online Inventory, and
the NMFS Google Earth Species list (NMFS 2017). Records were reviewed for the
following United States Geological Survey 7.5-minute quadrangles: San Rafael.
For the NMFS Species list, the San Rafael quad was identified within the range of
anadromous fish species. The NMFS species list is an intersection of FESA Listed
Species, Critical Habitat, EFH and Marine Mammal Protection Act Species Data within
California. It should be noted that identified features may be present throughout the
entire quadrangle or only a portion of it.
All species lists are included in Appendix B.
The special status species lists obtained from the CNDDB, CNPS, USFWS and NMFS
were reviewed to determine which species could potentially occur within the vicinity of
the BSA. The cumulative list (shown in Table 2, Section 3.2) includes numerous species
representing a variety of habitat types. The list includes each species’ protection status,
habitat information, status in the BSA, and supporting comments as necessary. Figures
4 and 5 show special status species occurrences within a 5-mile radius of the BSA.
The determination of whether a species could potentially occur within the BSA was
based on the availability of suitable habitat within and adjacent to the BSA, as well as
known occurrences of the species in or adjacent to the BSA according to the CNDDB.
Those species that could potentially occur in the BSA from habitat suitability or on known
occurrences in or within the vicinity of the BSA are discussed in Sections 4.2 and 4.3, as
applicable.

2.2.2 FIELD SURVEYS
2.2.2.1 General Biological Survey/ Vegetation Mapping
A general biological survey of the BSA was conducted by LSA biologist Anna Van Zuuk
on May 22, 2017. Mrs. Van Zuuk surveyed the BSA on foot. The naturally occurring
vegetation in the BSA was classified according to A Manual of California Vegetation,
Second Edition (Sawyer, Keeler-Wolf, and Evans 2008), as appropriate. Managed,
disturbed, or developed areas were classified according to their dominant plant species.
The names of the plant species are consistent with The Jepson Manual: Vascular Plants
of California, Second Edition (Baldwin, B. G., et. al., editors 2012).
2.2.2.2 Potential Jurisdictional Waters Determination and Delineation
No potential waters of the U.S. were identified in the BSA; therefore a jurisdictional
delineation was not conducted.
2.2.2.3 Tree Inventory
An inventory of native trees was conducted by Mrs. Van Zuuk on May 22, 2017. Data
was collected on species, diameter at breast height, and any notable characteristics.
The results of the tree survey are included in Appendix C.
2.3 Agency Coordination and Professional Contacts
No agency coordination has occurred for this project.
2.4 Limitations That May Influence Results
No problems or limitations were encountered during the research, fieldwork, or
document preparation that influenced the results presented herein.

Chapter 3 – Results: Environmental Setting
3.1 Description of the Existing Biological and Physical Conditions
3.1.1 BIOLOGICAL STUDY AREA
The Biological Study Area (BSA), totaling approximately 0.36 ac, extends along
Southern Heights Boulevard for approximately 315 ft (including the Southern Heights
bridge), and includes areas 10 ft east and 20 ft west of the roadway to accommodate
temporary construction access. The BSA is located just north of the intersection of
Meyer Road and Southern Heights Boulevard in the Southern Heights neighborhood of
San Rafael.
3.1.2 PHYSICAL CONDITIONS
The BSA is heavily disturbed and consists almost entirely of residential development,
landscaping, and ruderal/disturbed areas. One natural community, California Bay Forest,
occurs west of the existing bridge and extends downslope. There are no aquatic features
in the BSA. The bridge spans a steep ravine that slopes east to west with an elevation
that ranges from approximately 260 to 300 feet above mean sea level.
Land uses in the immediate vicinity consist of moderate density residential housing
scattered within steep canyons in Coastal oak woodlands. These communities give way
to dense urban and suburban areas.
Representative photos of the BSA are shown in Appendix D.
3.1.3 BIOLOGICAL CONDITIONS IN THE BIOLOGICAL STUDY AREA
3.1.3.1 Natural Communities and Other Habitat Types
As noted above, vegetation communities were classified based on the descriptions in
Sawyer, Keeler-Wolf, and Evans (2008), as applicable. One natural community occurs
within the BSA: California Bay Forest. Other habitat types not considered natural include
ruderal/disturbed, landscaped, and developed. Habitat types in the BSA are shown in
Figure 6 and summarized in Table 1.

California Bay Forest
The California bay forest community, totaling 0.12 ac, occurs west of the Southern
Heights Bridge and continues downslope. This area has a tree canopy dominated by
California bay (Umbellaria californica) with a few Coast live oak (Quercus agrifolia)
intermixed. The understory is sparse and dominated by Upright veldt grass (Ehrharta
erecta) with a few scattered toyon (Heteromeles arbutifolia), madrone (Arbutus
menziesii), and California buckeye (Aesculus californica) shrubs.
Ruderal/Disturbed
The ruderal/disturbed community is likely a former natural community that has been
subject to regular disturbance and now has a large component of ruderal species. The
vegetation that grows in these areas typically consists of species that are able to quickly
colonize following disturbance and can grow in poor soil conditions. In the BSA,
ruderal/disturbed areas total 0.07 ac and occur west of Southern Heights Boulevard on
roadsides and continuing downslope. Dominant plant species include: rattlesnake grass
(Briza maxima), ripgut brome (Bromus diandrus), Italian thistle (Carduus
pycnocephalus), and French broom (Genista monspessulana); dogtail grass (Cynosurus
echinatus), Italian ryegrass (Festuca perennis), foxtail barley (Hordeum murinum),
hedge mustard (Sisymbrium officinale), and hedge parsley (Torilis arvensis) are also
present.
Landscaped
Landscaping, totaling approximately 0.06 ac, is located east of Southern Heights
Boulevard and the Southern Heights Bridge. Plants associated with this community are
introduced and intensely managed by residential land owners. Species present include:
agapanthus (Agapanthus sp.), century plant (Agave americana), yellow jade plant
NES 21
(Crassula ovata), jasmine (Jasminum sp.), paperwhites (Narcissus papyraceus), prickly
pear cactus (Opuntia sp.), white bower vine (Pandorea jasminoides), rosemary
(Rosmarinus officinalis), Mexican bush sage (Salvia leucantha) and calla lily
(Zantedeschia sp.).
Developed
The developed areas in the BSA, totaling approximately 0.11 ac, consist of Southern
Heights Boulevard, the Southern Heights Bridge, and private driveways and walkways.
3.1.3.2 Description of Common Animal Species
The sections below discuss animal species observed and/or likely to occur within the
BSA.
Mammals
Mammals observed during the May 2017 survey include Eastern fox squirrel (Sciurus
niger) and mule deer (Odocoileus hemionus californicus). Other common species likely
to occur in the BSA include California ground squirrel (Otospermophilus beecheyi),
cottontail rabbit (Sylvilagus sp.), coyote (Canis latrans), raccoon (Procyon lotor), striped
skunk (Mephitis mephitis), and opossum (Didelphis virginiana).
Birds
Bird species observed during the May 2017 survey include: western scrub jay
(Aphelocoma californica) and northern mockingbird (Mimus polyglottos). These species
were either observed, overhead, or within trees located directly in or adjacent to the
BSA. Other common bird species expected to occur in the BSA include: band-tailed
pigeon (Columba fasciata), rock pigeon (Columba livia), American crow (Corvus
brachyrynchos), western bluebird (Sialia mexicana), European starling (Sturnus
vulgaris), American robin (Turdus migratorius), and mourning dove (Zenaida macroura).
Amphibians and Reptiles
No amphibians were observed during the May 2017 survey. Amphibian species likely to
occur in the BSA include: Sierran tree frog (Pseudacris sierra) and Western toad
(Anaxyrus boreas).
One reptile species was observed during the May 2017 survey – western fence lizard
(Sceloporus occidentalis). Other reptile species likely to occur in the BSA include:
western terrestrial garter snake (Thamnophis elegans elegans), western rattlesnake
(Crotalus oreganus), and common gopher snake (Pituophis catenifer).
-------------------------------------------------------------------------------------------------------------------------------------------------------■
NES 22
3.1.3.4 Invasive Species
Many non-native species have been part of the California landscape for the past 150
years. The BSA supports a number of noxious weed species including: black acacia
(Acacia melanoxylon), rattlesnake grass, ripgut brome, Italian thistle, upright veldt grass,
Italian ryegrass, French broom, English ivy (Hedera helix), foxtail barley, Himalayan
blackberry (Rubus armeniacus), hedge parsley, and periwinkle (Vinca major). While
most of these species are limited to moderately invasive, three seriously invasive
species – French broom, English ivy, and Himalayan blackberry – were observed in the
BSA.
3.1.3.5 Migration Corridor
Wildlife movement corridors are linear habitats that function to connect two or more
areas of significant wildlife habitat. These corridors may function on a local level as links
between small habitat patches (e.g., streams in urban settings) or may provide critical
connections between regionally significant habitats (e.g., deer movement corridors).
Wildlife corridors typically include vegetation and topography that facilitate the
movements of wild animals from one area of suitable habitat to another in order to fulfill
foraging, breeding, and territorial needs. These corridors often provide cover and
protection from predators that may be lacking in surrounding habitats. Wildlife corridors
generally include riparian zones and similar linear expanses of contiguous habitat.
Undeveloped lands in the vicinity of the BSA are intermixed with developed lands and
are highly fragmented; therefore, these lands do not provide suitable migration corridors
for wildlife.
3.1.3.6 Aquatic Resources
Runoff from Southern Heights Boulevard is collected and flows through a culvert
downslope into an adjoining neighborhood, ultimately outletting into Corte Madera Creek
which drains into San Francisco Bay. The ravine spanned by the Southern Heights
Bridge may convey surface runoff during the wet season, flowing west, but shows no
evidence of hydrology. Therefore, no aquatic resources were identified within the BSA.
-------------------------------------------------------------------------------------------------------------------------------------------------------■
NES 23
3.2 Regional Species and Habitats of Concern
Table 2 provides a list of special status species that could potentially occur in the region,
and therefore in the BSA. This list was compiled as described in Section 2.2.1. A review
was conducted of the specific habitats required by each species listed in Table 2, and
the specific habitats and habitat conditions present in the BSA. Based on this evaluation,
it was determined whether the species listed in Table 2 had potential to occur in the
BSA. Special status species that were observed, or determined to potentially occur in
the BSA based on availability of suitable habitat or other factors such as plucking posts,
scat, nests, dens, etc., are discussed more fully in Sections 4.2 and 4.3 of this report, as
applicable. Species determined unlikely to occur in the BSA based on these same
factors are documented accordingly in the table and not discussed further in this report.

Chapter 4 – Results: Biological Resources, Discussion of
Impacts and Mitigation
The project will result in impacts to California bay forest, consisting of 0.02 ac of
permanent impacts and 0.09 ac of temporary impacts (Table 3). The project will also
result in the removal of three trees, including two California bay trees, one 13 inches (in)
diameter at breast height (dbh) and another multi-trunked with a cumulative dbh of 46.5
in. Trees to be removed are listed in the Tree Inventory provided in Appendix C.

4.1 Habitats and Natural Communities of Special Concern
Natural communities of concern (i.e. riparian, wetlands, and oak woodlands) are
considered sensitive under CEQA and may be regulated by CDFW pursuant to Section
1602 of the CFGC, as described in Section 2.1.2.3. Riparian communities and wetlands
may also be regulated by ACOE and/or RWQCB if the community is determined to be
waters of the U.S., or waters of the State, as described in Sections 2.1.2.1 and 2.1.2.2.
Potential permitting requirements for impacts to these resources are discussed in
Section 5.4.
No natural communities of concern occur in the BSA.
4.2 Special Status Plant Species
No special status plant species were observed or are expected to occur in the BSA, as
shown in Table 2; therefore, no impacts are expected to occur to special status plants.
4.3 Special Status Animal Species Occurrences
No special status animal species were observed or are expected to occur in the BSA, as
shown in Table 2; therefore, no impacts are expected to occur to special status animals.
NES 42
Chapter 5 – Conclusions and Regulatory Determinations
5.1 Federal Endangered Species Act Consultation Summary
The proposed project will have no effect on any federally listed or candidate species
under FESA. Therefore, consultation within the USFWS and/or NMFS pursuant to
Section 7 of the FESA will not be required.
5.2 Essential Fish Habitat Consultation Summary
EFH was identified within all eight quadrangles of the NMFS Species list search;
however, no waterways were identified in the BSA. Therefore, EFH consultation with
NMFS will not be required.
5.3 California Endangered Species Act Consultation Summary
The proposed project will not impact any State listed species; therefore, no Incidental
Take Permit pursuant to Section 2081 of the California Fish and Game Code will be
required for this project.
5.4 Wetlands and Other Waters Coordination Summary
There are no wetlands or other waters of the U.S. in the BSA under the jurisdiction of
ACOE, RWQCB or CDFW. The project will not result in impacts to wetlands or other
waters.
5.5 Executive Order 11990 – Protection of Wetlands
There are no wetlands in the BSA. The project will not result in impacts to wetlands.
5.6 Migratory Bird Treaty Act and California Fish and Game Code
(Breeding Birds)
Disturbance of migratory birds during their nesting season (February 1 to August 31)
could result in “take” which is prohibited under the MBTA and Section 3513 of the
CFGC. CFGC Section 3503 also prohibits take or destruction of bird nests or eggs.
The following seasonal work restrictions will be implemented during construction to
minimize the potential for take of nesting birds:
1.If work must begin during the nesting season (February 1 to August 31), a qualified
biologist shall survey all suitable nesting habitat in the BSA for presence of nesting
birds. This survey shall occur no more than 10 days prior to the start of construction.
If no nesting activity is observed, work may proceed as planned. If an active nest is
discovered, a qualified biologist shall evaluate the potential for the proposed project
-------------------------------------------------------------------------------------------------------------------------------------------------------■
NES 43
to disturb nesting activities. The evaluation criteria shall include, but are not limited
to, the location/orientation of the nest in the nest tree, the distance of the nest from
the BSA, the line of sight between the nest and the BSA, and the feasibility of
establishing no-disturbance buffers.
2. Additionally, CDFW shall be contacted to review the evaluation and determine if the
project can proceed without adversely affecting nesting activities.
3. If work is allowed to proceed, a qualified biologist shall be on-site weekly during
construction activities to monitor nesting activity. The biologist shall have the
authority to stop work if it is determined the project is adversely affecting nesting
activities.
5.7 Executive Order 13112: Invasive Species
To avoid the introduction of invasive species into the BSA during project construction,
contract specifications shall include, at a minimum, the following measures.
1. All earthmoving equipment to be used during project construction shall be cleaned
thoroughly before arrival on the project site.
2. All seeding equipment (i.e. hydroseed trucks) shall be thoroughly rinsed at least
three times prior to beginning seeding work.
3. To avoid spreading any non-native invasive species already existing on-site, to off-
site areas, all equipment shall be thoroughly cleaned before leaving the site.
4. To avoid introduction of additional non-native species to the site, all fill dirt brought
onto the site must be weed free.
5.8. Executive Order 11988: Floodplain Management
The proposed project would not have significant adverse impacts to the existing
floodplain or significantly alter the hydraulics in the area. Therefore, the project would not
increase the risk of flooding.
5.9. City of San Rafael Tree Ordinance (Code of Ordinances
Chapter 11.12)
The project will result in the removal of two California bay trees and one black acacia.
According to the City of San Rafael Tree Ordinance, any City employees acting under
the scope of their employment by the City are not subject to the requirements of the
Ordinance. The City of San Rafael is the proponent of this Project, and therefore
mitigation for the loss of the trees is not required, since the tree ordinance is not
applicable.

Project Name: Southern Heights Boulevard Bridge Replacement Project
Subject: List of threatened and endangered species that may occur in your proposed project
location, and/or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, under the jurisdiction of the U.S. Fish and
Wildlife Service (Service) that may occur within the boundary of your proposed project and/or
may be affected by your proposed project. The species list fulfills the requirements of the
Service under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C.
1531 ).et seq.
Please follow the link below to see if your proposed project has the potential to affect other
species or their habitats under the jurisdiction of the National Marine Fisheries Service:
http://www.nwr.noaa.gov/protected_species/species_list/species_lists.html
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 ), Federal agencies are required toet seq.
06/01/2017 Event Code: 08ESMF00-2017-E-06033 2
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a biological
evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that
listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found in the "Endangered
Species Consultation Handbook" at:
http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF
Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle
Protection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq.
development of an eagle conservation plan
(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projects
should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing
impacts to migratory birds and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:
http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;
http://www.towerkill.com; and
http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office.

There is a total of 18 threatened, endangered, or candidate species on your species list. Species
on this list should be considered in an effects analysis for your project and could include species
that exist in another geographic area. For example, certain fish may appear on the species list
because a project could affect downstream species. See the "Critical habitats" section below for
those critical habitats that lie wholly or partially within your project area. Please contact the
designated FWS office if you have questions.

Subject: Completion of Section 106 for the Proposed Southern Heights Boulevard Bridge (Bridge No.
27C-0148) Replacement Project in the City of San Rafael in Marin County.
This memorandum serves to memorialize the completion of Section 106 of the National Historic
Preservation Act (NHPA) of 1966, as amended, compliance for the proposed Southern Heights
Boulevard Bridge (Bridge No. 27C-0148) replacement project in the City of San Rafael in Marin
County. The environmental review, consultation, and any other actions required by applicable
Federal environmental laws for this project are being, or have been, carried out by the California
Department of Transportation (Caltrans) pursuant to 23 U.S.C. 326 and the Memorandum of
Understanding executed by the Federal Highway Administration and Caltrans.
The studies for this undertaking were carried out in a manner consistent with Caltrans’ regulatory
responsibilities under Section 106 of the National Historic Preservation Act (36 CFR Part 800)
and pursuant to the January 2014 First Amended Programmatic Agreement Among the Federal
Highway Administration, the Advisory Council on Historic Preservation, the California State
Historic Preservation Officer, and the California Department of Transportation Regarding
Compliance with Section 106 of the National Historic Preservation Act, as it Pertains to the
Administration of the Federal-Aid Highway Program in California (Section 106 PA).
Caltrans, District 4, in cooperation with the City of San Rafael, in accordance with Stipulation
X.B.1 of the PA, determined that a Finding of No Historic Properties Affected is appropriate for
the undertaking as there are no historic properties within the project Area of Potential Effect
(APE). The Historic Property Survey Report (HPSR) and Archaeological Survey Report (ASR)
for the proposed project were approved by Caltrans Professionally Qualified Staff (PQS) on
January 18, 2018. The following properties have been determined not eligible for inclusion in the
National Register of Historic Places (NRHP) as a result of this study:

Project Description:
The proposed Southern Heights Bridge Replacement Project is located in the City of
San Rafael, Marin County, California (Attachment 1: Figures 1 and 2), within Caltrans
District 4. The project area includes a 436-foot-long and 60-foot-wide section of
Southern Heights Boulevard situated between Meyer Road and Pearce Road. The
project area is located approximately 0.5 miles south of downtown San Rafael, 0.9-
miles west of Highway 101, and 19-mile north of Greenbrae.
The project consists of the demolition of the existing bridge (Bridge No. 27CO148)
and the construction of a new bridge along Southern Heights Boulevard. The
proposed project will replace the existing bridge with a new structure accommodating
one 12-foot wide lane and bridge railings, resulting in an approximate bridge width of
15 feet. The new bridge type has not yet been determined, but the structure is
expected to be a 100-foot long, multi-span concrete or steel bridge.
The roadway alignment and grade will remain unchanged. The southern roadway
approach and retaining wall will begin approximately 20 feet south of the existing
southern bridge abutment. The new southern bridge abutment will be shifted north of
the driveway to 116 Southern Heights Boulevard. The northern roadway approach will
begin 45 feet north of the existing northern bridge abutment. The new northern bridge
abutment will be shifted south of the walking access path to 122 Southern Heights
Boulevard. A 115-foot long retaining wall will be constructed to the west of the existing
retaining wall to allow for the widened bridge. The new retaining wall is expected to be
a solider pile wall with steel H-piles and timber lagging with a concrete structural
section on the outside face.
No new right-of-way will be required for the new bridge or retaining walls. Temporary
construction easements (TCEs) are anticipated on the east and west sides of the
bridge to provide construction access. Utilities, including overhead power and
communication and underground water and natural gas, will be relocated.
Construction of the bridge will involve excavation for and construction of concrete
abutments and piers. The structure will be supported on cast-in-drilled-hole piles.
There is no waterway beneath the bridge, but a corrugated metal storm drain pipe that
will need to be temporarily relocated away from the structure during the construction.
Construction of the roadway approaches will involve the removal of existing

pavement, retaining walls and fences and the placement of fill material, aggregate
base, hot mix asphalt pavement, soldier pile and concrete retaining walls, and new
guard rails. Tree removal and removal of other vegetation along the slopes adjacent
to the bridge will be necessary for the project.
2. AREA OF POTENTIAL EFFECTS
In accordance with Section 106 Programmatic Agreement Stipulation VIII.A, the Area of
Potential Effects (APE) for the project was established in consultation with Karen
Reichardt, PQS Principal Investigator—Prehistoric and Historical Archaeology, Helen
Blackmore, PQS Principal Architectural Historian, and Louis Schuman, Local
Assistance Engineer, on March 14, 2017. The APE maps are in Attachment 2 of this
Historic Property Survey Report.
The horizontal APE for Archaeology is bounded by the existing right-of-way and
includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard. The
Archaeological APE includes 274 feet of paved roadway and 162 feet of existing bridge,
as well the land under the bridge and on either side of the roadway for 20 feet. This
area totals approximately 0.6 acres. The Archaeological APE incorporates the project
footprint that consists of the footprint of the existing bridge that is 162 feet long and 9
feet wide, the footprint of the proposed bridge that is 133 feet long and 16 feet wide, and
areas not included in the existing right-of-way including a staging area at the north end
of the proposed bridge footprint that is 114 feet long and approximately 16 feet wide,
and a staging area at the south end of the proposed bridge footprint that is 124 feet long
and approximately 17.5 feet wide. Depth of excavation is expected to reach 4-inches.
Vertical APE is 30 feet below surface, which includes all ground disturbing activities
such as removal and installation of bridge abutments, piers, footings, and railings.
The Architectural History APE includes the Archaeological APE and eleven adjacent
parcels that include Marin County Assessor Parcel Numbers (APN) 013-124-04 at 136
Southern Heights Boulevard, APN 013-124-05 (no physical address), APN 013-124-06

X Results:
• The record search indicates that there have been 13 cultural resource studies
conducted within a ½-mile of the Archaeological APE that cover less than
10% of the land within that radius. The Archaeological APE has not been
previously studied for cultural resources; however, one archaeological study
was conducted adjacent to the Archaeological APE on the south (S-10445)
that did not result in the identification of any archaeological resources
(Holman 1988). The study included the portion of the Architectural History
APE that includes the property at 10 Meyer Road.
• There are two cultural resources recorded on Department of Parks and
Recreation (DPR) 523 forms within a ½-mile of the Archaeological APE (P-
21-000594 and P-21-000645). P-21-000594 (CA-MRN-626/H) is a prehistoric

Native American shell midden site situated on an alluvial plain near the
historic San Francisco Bay margins that also contains a historic house
(Solomon and Campbell 1996). P-21-000645 (CA-MRN-313) represents the
general location of a prehistoric Native American “shell-ground” site that
appears to have been destroyed prior to 1910 (Nelson 1910). Neither site has
been evaluated to determine eligibility for listing on the National Register of
Historic Places.
• There are three cultural resources listed in the OHP’s Directory of Properties
in the Historic Property Data File for San Rafael, Marin County located within
the Architectural History APE, one of which is also located in the Architectural
APE. These include the houses at 116 Southern Heights Boulevard (P-21-
001008) and 122 Southern Heights Boulevard (P-21-001010), and the ca.
1930 Southern Heights Bridge (P-21-001009), all of which have a National
Resister Status code of 7N, meaning that they need to be re-evaluated to
determine eligibility for listing on the National Register of Historic Places. The
Caltrans Structure Maintenance & Investigations list of Local Agency Bridges
with Historical Significance lists the Southern Heights Bridge (sidehill viaduct)
as a Category 5 - Ineligible for a National Register listing.
• A field survey of the APE for archaeological resources was conducted by
Sally Evans, M.A, RPA on April 4, 2017. One historic isolated artifact was
identified within the APE and burned historic-era artifacts were observed at
116 Southern Heights Boulevard outside of the Archaeological APE. An older
house at 116 Southern Heights Boulevard burned down on the property prior
to the existing house built in 1971. Please see Attachment 4 ASR.
• The built environment survey was conducted by Stacey De Shazo, M.A., on
April 4, 5, 14, and 24, 2017. Ms. De Shazo evaluated the six built environment
resources over 50 years of age within the APE. Three of the built environment
resources are currently listed in the San Rafael Historic Resources Inventory,
but these three had not yet been evaluated for listing in the California
Register or National Register of Historic Places. All six built environment
resources were determined not eligible for listing in the National Register of
Historic Places as a result of this study. Please see Attachment 5 HRER.
• Historic-era artifacts were observed during survey of the Architectural History
APE at 116 Southern Heights Boulevard/APN 013-132-03 where the property
owner confirmed that an older house had burned down on the property prior
to the existing house built in 1971. The historic-era artifacts are outside of the
Area of Direct Impact (ADI) and Archaeological APE and will be neither
directly nor indirectly affected by the Project. There is no potential for indirect
effects because they are located too far away to be impacted by vibration and

the Project will not result in increased public access which would put it at risk
for vandalism or looting. The historic-era artifacts are located outside of the
Archaeological APE that includes all areas that will be directly affected by the
Project’s proposed ground disturbing activities. They are located within the
Architectural History APE, which is larger than the Archaeological APE
because it includes the ADI but also takes into account all adjacent parcels
that contain built environment resources that have the potential to be
indirectly affected (i.e. visual, vibration, or noise impacts) by the proposed
Project. The historic-era artifacts are outside of the Archaeological APE and
will not be affected directly or indirectly by the Project; therefore, further
consideration of the historic-era artifacts is not warranted for purposes of this
Project.
• Additionally, pursuant to Section 5020.1(k) of the California Public Resources
Code, there are three built-environment resources within the APE that are
considered historical resource for the purposes of CEQA because they are
listed in the OHP’s Directory of Properties in the Historic Property Data File
for San Rafael, Marin County. The two resources located adjacent to the APE
include the houses at 116 Southern Heights Boulevard (P-21-001008) and
122 Southern Heights Boulevard (P-21-001010), both of which have a
National Register Status code of 7N, meaning that they need to be re-
evaluated to determine eligibility for listing on the NRHP. The resource
located within the APE includes the ca. 1930 Southern Heights Bridge (P-21-
001009) that also has a National Register Status code of 7N. The Caltrans
Structure Maintenance & Investigations list of Local Agency Bridges with
Historical Significance that is on file at the NWIC includes the Southern
Heights Bridge (sidehill viaduct), which is listed as not eligible for the NRHP.
• According to Caltrans’ geoarchaeological overview of the region and
preliminary soil analysis, the Archaeological APE is not sensitive for surface
or buried archaeological deposits based on the age of the landform which
predates human occupation in North America in addition to extensive erosion
events associated with the landform (Byrd et al. 2017; Meyer and Rosenthal
2007).

SUMMARY OF FINDINGS
The City of San Rafael is proposing the Southern Heights Bridge Replacement Project (Project) under the Highway Bridge Program administered for the Federal Highway Association by the California Department of Transportation (Caltrans), District 4. The project consists of the demolition of the existing bridge, constructed in ca. 1930, and the construction of a new bridge along Southern Heights Boulevard. The existing ca. 1930 bridge is a one-lane stringer structure with a timber deck supported on timber bents with concrete pedestal footings that was first rehabilitated in 1958, which included concrete piers and retaining walls and replacement of defective wooden members; and in 1981 the bridge was again reinforced with concrete wall abutments. The bridge (Bridge No. 27CO148; MR #2) has a width of nine feet and is 162 feet long with a wood deck and wood railings. The project includes the demolition of the existing bridge, which is being replaced due to structural deficiencies and its overall poor condition. The proposed project will replace the existing bridge with a new structure accommodating one 12-foot wide lane and bridge railings, resulting in an approximate bridge width of 15 feet. The new bridge type has not yet been determined, but the structure is expected to be a 100-foot long, multi-span concrete or steel bridge. The work will occur within a section of the Southern Heights Boulevard that traverses north/south through a hilly residential area on the northeast slope of the Southern Heights Ridge, and carries local traffic.
The Area of Potential Effects (APE) is located approximately 0.5 mile south of downtown San Rafael, 0.9 mile west of Highway 101, and 19 miles north of Greenbrae. The Architectural History APE was delineated to incorporate all built environment resources that may be directly or indirectly affected by the proposed Project. The APE includes City right-of-way as well as all parcels immediately adjacent to the bridge (See Appendix A for Architectural History APE map).
Evans & De Shazo, LLC (EDS) conducted the research to address the built environment resources within the Architectural History APE. EDS identified a total of six built environment resources that include five buildings dating between 1907 and 1951 and the Southern Heights Bridge (Bridge No. 27CO148) constructed circa 1930. Each of these built environment resources required formal evaluation. The circa 1930 bridge is currently listed in the Caltrans Historic Bridge Survey as a category 5 bridge that is not eligible for listing in the NRHP; however, the bridge is also currently listed on the City of San Rafael Historic Resource Inventory (HRI) and the Office of Historic Preservation’s Historic Property Directory with a National Register Status code of 7N, meaning it needs to be reevaluated.
LSA determined that of the six built environment resources evaluated, none appear to meet the criteria for listing in the National Register of Historic Places (NRHP). This conclusion is pursuant to Stipulation VIII.C of the First Amended Programmatic Agreement Among the Federal Highway
Administration, the Advisory Council on Historic Preservation, the California State Historic
Preservation Officer and the California Department of Transportation Regarding Compliance with
Section 106 of the National Historic Preservation Act, as it Pertains to the Administration of the
Federal-Aid Highway Program in California (Section 106 PA) (Caltrans 2014).

[MR #2]), none appear to meet the criteria for listing in the California Register of Historical Resources (CRHR). The DPR 523 forms for all six resources are in Appendix C.
Historic-era artifacts were observed during survey of the Architectural History APE at 116 Southern Heights Boulevard/APN 013-132-03 where the property owner confirmed that an older house had burned down on the property prior to the existing house built in 1971. The historic-era artifacts are outside of the Area of Direct Impact (ADI) and Archaeological APE and will be neither directly nor indirectly affected by the Project. There is no potential for indirect effects because they are located too far away to be impacted by vibration and the Project will not result in increased public access which would put it at risk for vandalism or looting. The historic-era artifacts are located outside of the Archaeological APE that includes all areas that will be directly affected by the Project’s proposed ground disturbing activities. They are located within the Architectural History APE, which is larger than the Archaeological APE because it includes the ADI but also takes into account all adjacent parcels that contain built environment resources that have the potential to be indirectly affected (i.e. visual, vibration, or noise impacts) by the proposed Project. The historic-era artifacts are outside of the Archaeological APE and will not be affected directly or indirectly by the Project; therefore, further consideration of the historic-era artifacts is not warranted for purposes of this Project.

1.0 PROJECT DESCRIPTION
The proposed Southern Heights Bridge Replacement Project is located in the City of San Rafael, Marin County, California (Attachment 1: Figures 1 and 2), within Caltrans District 4. The project area includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard situated between Meyer Road and Pearce Road. This section of Southern Heights Boulevard traverses north/south through a mountainous residential area on the northeast slope of the Southern Heights Ridge, which divides San Rafael from the communities of Larkspur, Greenbrae and Ross, and carries local traffic. The project area is located approximately 0.5 miles south of downtown San Rafael, 0.9-miles west of Highway 101, and 19-mile north of Greenbrae.
The project consists of the demolition of the existing bridge (Bridge No. 27CO148) and the construction of a new bridge along Southern Heights Boulevard. The existing bridge is a ca. 1930 one-lane stringer structure with a timber deck supported on timber bents with concrete pedestal footings and reinforced concrete wall abutments. The concrete piers and retaining walls, as well as defective wooden deck members were replaced in 1958, and in 1981 the bridge was again reinforced with concrete wall abutments. The bridge has a width of 9 feet and is 162 feet long with a wood deck and wood railings. The bridge is being replaced due to structural deficiencies and its overall poor condition. The proposed project will replace the existing bridge with a new structure accommodating one 12-foot wide lane and bridge railings, resulting in an approximate bridge width of 15 feet. The new bridge type has not yet been determined, but the structure is expected to be a 100-foot long, multi-span concrete or steel bridge.
The roadway alignment and grade will remain unchanged. The southern roadway approach and retaining wall will begin approximately 20 feet south of the existing southern bridge abutment. The new southern bridge abutment will be shifted north of the driveway to 116 Southern Heights. The northern roadway approach will begin 45 feet north of the existing northern bridge abutment. The new northern bridge abutment will be shifted south of the walking access path to 122 Southern Heights. A 115-foot long retaining wall will be constructed to the west of the existing retaining wall to allow for the widened bridge. The new retaining wall is expected to be a solider pile wall with steel H-piles and timber lagging with a concrete structural section on the outside face.
Neither the new bridge nor retaining walls will require new right-of-way. Temporary construction easements (TCEs) are anticipated on the east and west sides of the bridge to provide construction access. Utilities, including overhead power and communication and underground water and natural gas, will be relocated. It is not yet clear if the overhead utility relocations will be accommodated within the existing right-of-way or if utility easements will be needed for the overhead piles and wires. The water and gas lines will be relocated onto the new bridge.
Construction of the bridge will involve excavation for and construction of concrete abutments and piers. The structure will be supported on cast-in-drilled-hole piles. There is no waterway beneath the bridge, but a corrugated metal storm drain pipe that will need to be temporarily relocated away from the structure during the construction. Construction of the roadway approaches will involve the removal of existing pavement, retaining walls and fences and the placement of fill material, aggregate base, hot mix asphalt pavement, soldier pile and concrete retaining walls, and new guard

rails. Tree removal and removal of other vegetation along the slopes adjacent to the bridge will be necessary for the project.
1.1 AREA OF POTENTIAL EFFECTS
For purposes of this Project, two APEs were established: an Archaeological APE that includes all areas that will be directly affected by the Project’s proposed ground disturbing activities, and an Architectural History APE which includes the area of direct effect but also takes into account all adjacent parcels that contained built environment resources that have the potential to be indirectly affected (i.e. visual, vibration, or noise impacts) by the proposed Project. Please see Appendix A for the APE map.

2.0 RESEARCH METHODS
Pre-field, background, and resource-specific research pertaining to the history of the Architectural History APE was conducted, as well as in-depth research related to historical themes and contexts associated with the surrounding planned environment and its development.
2.1 RECORDS SEARCH AND ARCHIVAL RESEARCH
Research included a record search at the Northwest Information Center (NWIC) of the California Historical Resources Information Systems (CHRIS) (File# 16-1500) located in Rohnert Park, California to determine the presence or absence of previously recorded historical resources located within a half-mile of the Architectural History APE, and to identify areas of previous cultural resource evaluations. Details regarding the NWIC research are provided within the Archaeological Survey Report (ASR) prepared for this project (EDS 2017). Of the six properties identified by EDS as needing evaluation, three of the resources were previously identified as part of the City of San Rafael’s 1978 Historic Resources Inventory and listed in the 1986 San Rafael Historical/Architectural Survey; therefore, they are considered historical resources for purposes of CEQA per §15064.5(a)(2). Further detailed historic research utilizing primary and secondary documentation available at local repositories and online was also conducted. Information obtained was used to support the development of historic themes and contexts related to the history of the area and the planned built environment associated with built environment resources within the Architectural History APE. This additional in-person and on-line research also provided further understanding of the architectural style, chronology of ownership, construction and alteration history, and potentially significant events associated with the built environment resources located within the Architectural History APE to determine eligibility for listing on the National Register of Historic Places (NRHP) and the California Register of Historical Resources (CRHR).
EDS reviewed the following:
• National Register of Historic Places
• California Register of Historical Resources
• California Inventory of Historic Resources
• California Historical Landmarks
• California Points of Historical Interest
• Caltrans Historic Highway Bridge Inventory
• Caltrans Historic Bridge Inventory
EDS visited the following local research facilities and repositories:
• Marin History Museum, Novato, California
• Marin County Assessor/Recorder Office, San Rafael, California
• Marin County Library/California Room, San Rafael, California

Additionally, the City does not know why it was ever included in the first place and the City has stated that they will likely remove it from their local inventory. In her January 5, 2018 e-mail Ms. Henderson, referring the Foundation’s records, the Foundation does “not have sufficient information on the significance of the bridge or the Section 106 process” and because the Foundation was not included in the planning stages, they lack information on “any alternatives that may have been discussed” during those planning stages that preceded this consultation effort. As a result, the Foundation has no comment on the Project. LSA closed this consultation loop with thanks and assurance that her wish to be included in the decision-making process in the initial planning stages will be conveyed.
2.3 HISTORICAL THEMES IDENTIFIED
The built environment cultural resources identified in the APE reflect the historic theme of growth and development that occurred in San Rafael; however, development in and around the city was heavily influenced by other historical themes such as transportation. The themes identified were used to establish the historical context in which these resources were evaluated in order to determine their eligibility for listing in the NRHP and the CRHR. Please see Section 4 for an historical overview that focuses on the themes identified which includes the planned development of Southern Heights and the Good Roads Movement.

3.0 FIELD METHODS
Section 106 regulations require a "reasonable and good faith effort" to identify historic properties (36 CFR § 800.4[b][1]). The purpose of the historic resource field survey was to identify, record, and evaluate all built environment resources within the Architectural History APE that have the potential to meet the NRHP and the CRHR criteria. During the field survey, EDS considered built environment resources such as buildings, structures, objects, districts, and non-archaeological sites within the Architectural History APE for eligibility to be listed on the NRHP/CRHR under criteria A/1, B/2, and C/3, and in rare circumstances, under Criterion D/4. Field methods followed the Caltrans' Volume 2 - Standard Environmental Reference, Chapter 7: Built-Environment Resources Evaluation and
Treatment and the Caltrans Code of Safe Surveying Practices.
Stacey De Shazo, M.A. who qualifies as a PQS Principal Architectural Historian, conducted the field survey of the Architectural History APE on April 4, April 5, and April 24, 2017. During the field survey, EDS Principal Architectural Historian, Stacey De Shazo, M.A., identified six properties that consist of five built environment resources that date from 1907 to 1951, and one structure, identified as the Southern Heights Bridge that warranted evaluation. Five built environment cultural resources identified within the Architectural History APE located at 108 Southern Heights Blvd, 104 Southern Heights Blvd, 65 Pleasant Lane, 75 Pleasant Lane, and 90 Pleasant Lane were determined to be exempt from further evaluation under the category of “between 30 and 50 years old” pursuant to Attachment 4 of the Section 106 PA. During the field survey, EDS assessed, photographed, and documented the built environment resources on DRP 523 forms (See Appendix C).
EDS also talked with the property owners of 136, 126, 122, 108, and 104 Southern Heights Boulevard, as well as the property owner at 10 Meyer Road. Each property owner provided details regarding their property and the surrounding neighborhood, as well as information regarding the history of the Southern Heights Bridge.

4.0 HISTORICAL OVERVIEW
4.1 EARLY HISTORY OF SAN RAFAEL
In the early nineteenth century, Spanish explorers, missionaries, and settlers lived in the area that is now known as San Rafael. The mission fathers chose the area to build an asistencia (assistance) hospital to treat the Native Americans from Mission Delores in San Francisco that were sick. On December 14, 1817, in what is now downtown San Rafael. Mission San Rafael Arcángel was founded by Father Vicente de Sarria under the patronage of San Rafael Arcángel, the angel of bodily healing. It was the 20th mission in the Spanish colonial province of Alta California, and by the end of the first year, the asistencia had a population of over 300 and became the first permanent Spanish establishment north of the San Francisco Bay. On October 19, 1822, San Rafael was declared independent of Mission Dolores and received full mission status. In 1821, following the Mexican War of Independence, Mexico had declared its independence from Spain and Alta California was soon under the control of Mexico. During this time, San Rafael was a small village that consisted of the adobe Mission San Rafael building, an adobe mission church, adobe mission walls, small houses for the “neophytes”, mission guest houses, a kitchen, an adobe Indian house, a cemetery, and several adobe buildings used for unknown purposes.1
In 1833, the Mexican government secularized the missions of Alta California, stripping them of their wealth and redistributing vast landholdings to favored Mexican citizens, who were often soldiers loyal to Mexico during the Mexican War of Independence. In 1840, Governor Juan Bautista Alvarado granted an 8,877-acre rancho, called Rancho Punta de Quentin Cañada San Anselmo, to Juan (John) B.R. Cooper. The Rancho encompassed the southern portion of San Rafael, the San Quentin peninsula, and the present-day towns of Ross, Kentfield, and part of San Anselmo. Cooper was married to General Mariano Vallejo’s sister, Encarnacion, and became a naturalized Mexican citizen in 1830. Cooper, who spent little time at his rancho, hired Timothy Murphy to look after his cattle and manage local Native Americans that were supplying the labor force on the rancho (Mason 1971:48). In 1847, Cooper sold logging rights on the rancho to the U.S. military for payment of $5 per 1,000 board feet cut (Spitz 2006:34). In 1844, Governor Micheltorena awarded Timothy Murphy three contiguous parcels – San Pedro that included portions of present-day San Rafael, Santa
Margarita, and Las Gallinas – as a single land grant that totaled 21,678-acres. In 1847, Murphy was appointed the administrator of the Mission San Rafael, acting at an agent for over 1,400 Native Americans still living in and around the mission (Marin History Museum 2008).
4.1.1 Early American Period (1848 – 1900)
By 1848, the once small village of San Rafael had become an agricultural center within the lands that had been developed by Murphy. In 1849, Murphy built an adobe house between present-day Fourth and Fifth Streets that faced C Street. The adobe was the first private dwelling built in San Rafael and was located within the original town plat, which later became the center of the town (Spitz 2006:38). The adobe was occupied by Don Antonio Osio, as Murphy continued to reside in the Mission Buildings (Munro-Frasier 1880:323). After California achieved statehood in 1850, Marin County was established as one of the state’s first 27 counties, and San Rafael was one the county’s

four original townships, as well as the county seat. In 1850, the first town lots were laid out and by 1851 a post office was established. In 1866, the editor of the Marin County Journal published the following recollection of San Rafael from 1851 (Marin County Library 2017),
“San Rafael boasted ten houses besides the Mission buildings; one store, one boarding house, and one whiskey mill. The buildings were all makeshifts except the residence of the late Timothy Murphy now owned and used by the county as a Court House; no fencing or other improvements were visible save a corral or two.”
Murphy died in 1853, and his adobe was sold to Timothy Mahon. Mahon either donated or leased the building to the city and it served as the county courthouse until a new one was constructed in 1872 (Kyle 2002). San Rafael was officially incorporated in 1874, and at the time of incorporation, it included 160 acres, centered at Fourth and B streets, and 600 residences (Spitz 2006:112). During this time, San Rafael grew slowly due its lack of industry and isolation from San Francisco. This all changed with the coming of the ferry and the railroad in 1870 when the San Rafael & San Quentin Railroad (SR&SQ) was established on March 21, 1870 that allowed quick travel from downtown San Rafael southeast to the ferry terminal at Point San Quentin. The coming railroad changed the character of San Rafael from a small isolated town of approximately 841 people in 1870 to approximately 2,276 in 1880.
In 1873, the Architectural History APE was part of a 549-acre property owned by William Tell Coleman. Coleman was born in Kentucky and came to California during the Gold Rush. Coleman never wielded an axe or a pick, instead he earned his fortune by selling tools, wares and other supplies to miners in Sacramento and Placerville before moving to San Francisco in 1850 and starting the William T. Coleman & Company. Coleman was extremely successful in the merchandising business, and was a prominent local figure. In 1851, he founded the Committee of Vigilance in San Francisco, which was established to restore order to the city during a time when vigilante justice was common. In 1856, he established a steamship line between New York and San Francisco, and moved to New York to manage his new business. He came to San Rafael in 1871 and paid $84,000 for 1,100 acres of land that included the 549-acre property within the Architectural History APE and 915acres north of the SR&SQ railroad. Coleman hired Golden Gate Park superintendent and civil engineer William Hammond Hall (1846 – 1934) to lay out the Coleman subdivision and he planted thousands of trees and well-nursed gardens. Coleman was influential in the success of many developments in San Rafael including the Marin County Water & Power Company, promoting the railroad, and partner to building the Hotel Rafael. By the 1880s, due in part to the efforts of Coleman, San Rafael was an established town with major institutions and business, but it also remained a resort town that catered not only to the wealthy, but to working-class travelers as well. Accommodations included luxury hotels, cottages, summer homes, and boarding houses. A photograph taken in the 1870s appears to have been taken from Meyer Road or Southern Heights Boulevard and is looking down “D” Street towards the town of San Rafael (Image 1). Growth during this time was supported by Hansen & Lund Lumber Yard and Isaac Shaver’s Pioneer Planning Mill & Lumber, Co. According to Diana Painter (Painter 2013), during this time “Architects from San Francisco were hired by wealthy clients in San Rafael to design their mansions and by investors to design their hotels”.

The 1906 earthquake shook San Rafael, jolting many homes off their foundations and knocking over chimneys and rooftops; but the biggest effect of the earthquake was the dramatic increase in population as people fled San Francisco (Spitz 2006). The rail line via the ferry continued to be the only way to travel between San Francisco and San Rafael until the construction of the Golden Gate Bridge in 1937, which greatly improved access to San Rafael (Kyle 2002; Miller 1958; Spitz 2006).
4.2 PLANNED DEVELOPMENT OF SOUTHERN HEIGHTS
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of open land south of downtown San Rafael, which includes the land that encompasses the Architectural History APE. According to the 1892 Marin County Map, 252 acres of the 549 acres of land owned by Coleman, where the Architectural History APE is located, was purchased by business partners John William Mackay and James C. Flood. MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in Nevada that ultimately produced more than $500 million worth of silver. At some point, the land owned by Flood and Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion of the 252 acres of land to William L. Courtright and his wife Eloisa Courtright, which included the Architectural History APE, the land along Southern Heights Boulevard, as well as land east and north of Southern Heights along present-day Courtright Road. By 1910, Courtright was selling parcels for development along Southern

The 1924 Sanborn Fire Insurance map shows the development of Southern Heights Boulevard, including the four buildings evaluated in this study, the surrounding neighborhood, and the location of a wood plank bridge along Southern Heights Boulevard.
The 1924 Sanborn map shows additional development in the area as well as the addition of the garage located within Assessor Parcel Number (APN) 013-124-05 and associated with the property at 126 Southern Heights Boulevard. During this time, the two lots, which are adjacent and south of the property located at 116 Southern Heights Boulevard remained undeveloped. However, according to a conversation with the property owner of the 1971 house at 108 Southern Heights Boulevard (APN 013-132-03), there was an older house that burned down on the property. The field survey of this property revealed evidence of a fire in the form of burned historic-era artifacts, and was confirmed again during a personal conversation with the property owner. The updated 1950 Sanborn map reveals that most of the housing development along Southern Heights Boulevard occurred prior to 1924, and that by 1950 the two lots that include 104 and 108 Southern Heights Boulevard were vacant; however, as previously indicated, the lot at 108 Southern Heights Boulevard may have contained older house that was replaced by the current 1971 house.
4.3 THE GOOD ROADS MOVEMENT
During the late 1890s and early 1900s, transportation reform efforts throughout the country took place and the national “Good Roads Movement” emerged with the goal of improving the condition of local roads. The popularity of bicycling gave impetus to the movement, and bicyclers aligned with the farmers in demanding smooth, all-weather roads. It was essentially a rural grass roots movement in which cyclists, farmers and their families lobbied for better roads. States began to heed the public outcry for better roads and formed statewide “Good Roads” organizations. In Iowa, for example, the Governor called the first Iowa Good Roads Association meeting in April of 1903, a meeting which signaled a shift in control of roads from local to state governments.
The Southern Heights Bridge, although constructed primarily to allow for one-way auto traffic, was also utilized as a local footbridge and as a way to access downtown San Rafael by avoiding the more heavily trafficked “D” Street that is below and west of Southern Heights Boulevard (Painter 2013). The City of San Rafael constructed the timber stringer bridge along Southern Heights Boulevard in ca. 1930 to also link the developing neighborhoods of Picnic Valley and “Bush’s Tract”, which includes Southern Heights Boulevard, to provide a faster route to reach downtown San Rafael. During the early twentieth century, the growth of the City of San Rafael was dependent upon community planning and development enhancements that served the increased population and communities living further from the downtown. As a part of city improvements to the planned development along Southern Heights Boulevard, the City of San Rafael set out to construct access roads to downtown and roads that could be used by those who moved to San Rafael and commuted into San Francisco via the ferry. The San Francisco Bay Area ferry services played an important role in the development of San Rafael and Marin County. The ferry service at one point constituted the greatest water transit system in the world. From the Gold Rush until the completion of the Golden Gate Bridge in 1935, ferries provided the only transportation across the San Francisco Bay to San Rafael.

"In 1930, forty-three ferryboats, the largest number to have ever operated on the bay, carried a total of forty-seven million passengers and more than six million automobiles from shore to shore. Each day, fifty to sixty thousand people crossed the bay between San Francisco and Alameda; 25 percent of them rode in automobiles” (Nancy and Roger Olmstead papers, 1847 -2007).
The construction of Southern Heights Boulevard allowed for further development of the land, as it provide additional access to residents in the area and was used to market lots being sold for housing development along Southern Heights, which included vacation homes for the wealthy and commuters. Several houses are located directly adjacent to the bridge, and the property located at 122 Southern Heights Boulevard (MR #3) has a front gate that opens directly onto the bridge, providing a unique association with the bridge and surrounding houses. When the Southern Heights Bridge was constructed, timber stringer bridges were the standardized type of bridge constructed throughout the country. Since it was a lower cost bridge to build with easy working characteristics and materials were in plentiful supply, the stringer style bridge made a logical choice for many local small bridge projects, including the Southern Heights Bridge. “Although in the 20th century concrete and steel replaced wood as the major materials for bridge construction, wood is still widely used for short-and medium-span bridges” (Ritter 1990:1-1).
By the early 1950s, the Southern Heights Bridge had seen at least 20 years of automobile traffic and survived several local earthquakes and fires. However, in 1954 a fire that destroyed a home along Southern Heights Boulevard was in-part blamed on the Southern Heights Bridge’s inability to support the local fire departments ten- to twelve-ton fire engines. By 1955, the City of San Rafael street superintendent recommended that the bridge be repaired or torn down, and closed the bridge to pedestrian and vehicular traffic until the city could decide on its fate. Ultimately, the City Council decided that the amount of vehicular traffic did not warrant any spending for reconstruction let alone repairing the guard rails (Daily Independent Journal 1954; Daily Independent Journal 1955).
In 1958, after the bridge was closed for over two years due to it being deemed “unsafe”, the City Council voted to rehabilitate the bridge. The city awarded the contract to Howard R. Bru construction, who won the project based on the lowest bid at $21,781 (Daily Independent Journal 1958). The work included installing concrete piers, replacing defective wooden members of the deck, and rebuilding the approaches. The bridge was in service another 23 years prior to its second rehabilitation that occurred in 1981. The 1981 rehabilitation included new concrete abutments and additional support. Today, the existence of new materials and technology has made steel and concrete the materials of choice for constructing bridges.
4.4 ARCHITECTURAL CONTEXT
4.4.1 Architectural Styles
The Southern Heights Boulevard neighborhood, which is historically referred to in deeds dated from the early twentieth century as Bush’s Tract, was originally marketed in the early 1900s as “a paradise on earth” to build a “manor” style house that served as a “summer home” (Petaluma Daily Courier, February 28, 1918). During the early 1900s, the houses that were constructed within the Architectural History APE included a single Dutch Colonial Revival style house and several Vernacular

style houses with Craftsman-style details. As the community of San Rafael grew following-World War II, the neighborhood grew as well, and parcels that were previously vacant were improved with single-family houses. During this time, additional architectural styles within the Architectural History APE included a Contemporary house and two Neo-Mansard houses. This eclectic mix of styles represents the origins of the neighborhood as a developed community with ”retreat”-style homes, and its later development from the 1950s through the 1970s as a neighborhood with a mix of architectural styles. That mix represents the periods of growth within the broader community, and also the pattern of individually designed and built houses within the City of San Rafael and Marin County. The mix of architectural styles —which is typical within developing neighborhoods and communities throughout California—is often based on personal preference and can derived from a combination of styles.
4.4.1.1 Vernacular
A useful approach to understanding what vernacular style is, can begin by defining what it is not. That is, vernacular architecture is not overly formal or monumental in nature, but rather is represented by relatively unadorned construction that is not designed by a professional architect. Vernacular architecture is the commonplace or ordinary building stock that addresses a practical purpose with a minimal amount of flourish or otherwise traditional or ethnic influences (Upton and Vlach 1986:xv-xxi, 426-432).
The historical roots of the Vernacular style in the United States dates from colonial settlement during the 16th and 17th centuries. European immigrants, either of modest independent means, or financed with corporate backing, brought with them a wood-based building tradition. From this combination came a new building tradition associated with unsettled and heavily forested land and a young population. This new style, vernacular style, was “characterized by short-lived or temporary dwellings focused on the family and distinct from the place of work” (Jackson 1984:85-87). Typically associated with older, hand-built rural buildings in remote or rural, agricultural settings, vernacular architecture can also include modern, pre-fabricated, general purpose steel buildings used as shop space, warehouses, discount-clearance centers and many other uses (Gottfried and Jennings 2009:9-16).
4.4.1.2 Craftsman (1900-1940)
“Craftsman” is a style associated with early an early-20th century architectural and design movement. Seeking to emphasize hand-made products that harkened to a pre-industrial past, the Craftsman styles residential buildings suited tourist families seeking an inexpensive second or vacation home suited to the environment of an alpine lake. As applied to a small residence, typically a bungalow, its general rustic qualities, small building footprint, and open floor plan created an affordable and easily reproduced was affordable and easy to construct. This style was popularized by Pasadena architects and brothers Charles and Henry Greene. Sourcing their initial design from the bungalows of the South Pacific, the Greenes began around 1900 to design simple residential buildings that captured California’s al fresco lifestyle. Several style influences—notably the English Arts and Crafts movement—stressed the superior qualities of hand-made craftsmanship from a pre-industrial era. Unnecessary ornament was removed to reveal a more authentic form and shape using locally-based materials, such as pine and fir. In the Lake Tahoe Basin, local builders incorporated these concepts broadly to design modest, simple, wood-framed houses clad in

unpainted or lightly stained shingles to develop an organic, rusticated architecture that used local materials in ways sensitive to the local setting. The Craftsman Bungalow was given wide exposure via magazines and pattern books, with some books offering kits of pre-cut lumber and an assembly plan. As a result, the one-story Craftsman Bungalow was the most popular small house in the country (Lancaster 1986:79-106; McAlester and McAlester 2003:454).
4.4.1.3 Dutch Colonial Revival (1890 – 1915)
The term "Colonial Revival" refers to a rebirth of interest in the early English and Dutch houses of the Atlantic Seaboard. The style was re-introduced at the Philadelphia Exposition of 1876, which marked the centennial of the signing of the Declaration of Independence. Many of the buildings designed for the exposition were based on historically significant colonial designs. At about the same time, several national organizations published a series of articles on eighteenth century American architecture, which appeared in American Architect and Harpers magazines. The renewed interest in colonial architecture fueled by the centennial and the exposure received by the Dutch Colonial Revival style in national publications helped to make it popular throughout the country. The style was found in both urban and rural environments, though most examples that survived into the late nineteenth century were rural. Dutch Colonial Revival residential architecture often displays regional variations that reflect available local resources that include the stone, brick, and wood as building materials. Dutch Colonial Revival architecture is widely recognized by the gambrel roof, although this roof type was not used exclusively. Gambrel roofs were often found in New Jersey and the Hudson River Valley early in the colonial period, and later in New York. The earliest Dutch Colonial Revival houses were constructed one-room deep and with steeply pitched roofs.
As homes became larger, these steeply pitched roofs proved vulnerable to wind stresses and precipitation. As such, some houses featured an upper and lower portion of different pitches. Character-defining features of the Dutch Colonial Revival style include clapboard or brick exterior cladding, front or side gambrel roofs, full-width recessed or projecting porches, and simple building forms. They are typically, one or two stories in height. Roof dormers are typically wide with shed roofs. Classical detailing is often restrained and includes pediments, columns or pilasters, multi-paned double-hung sash windows, and fixed shutters. In California, early examples of Dutch Colonial Revival architecture were often blended with the influences of the Shingle or other Victorian era styles.
4.4.1.4 Contemporary (1945 – 1975)
Contemporary architecture is widely recognized by its clean lines, geometric planes and surfaces, exposed post and roof beams, and lack of applied ornamentation. Stone and wood are often used to add warmth, but form and structure are paramount. Frank Lloyd Wright-influenced buildings are considered a variant of this style along with examples influenced by Joseph Eichler. The landscape of the property is also important, as it provides the style’s setting. By 1951, the key elements of the Contemporary style include a shed roof, split-level, warm, natural, stained wood, and large picture windows that extend the interior living spaces. By the late 1940s and early 1950s, builders began to recognize the value of well-designed, affordable houses in attracting the middle-class consumer, and many began working with architects to develop new looks for their model homes.

Along with the traditional Spanish and Colonial Revival styles of architecture, the clean lines and simple geometry of the Contemporary style proved to be well-suited to the low, horizontal massing of the prefabricated Ranch House. These qualities became quite popular with fashion-conscious homebuyers of the period. Architects also began to incorporate modern open floor plans into their interior designs, often merging the dining, living room, and kitchen areas into one common living space. Among the most distinctive early Contemporary style Ranch houses was the “Eichler house,” which was first designed by Stephen Allen and Robert Anshen in 1949 for builder Joseph Eichler and was later modified by Los Angeles architects A. Quincy Jones and Frederick Emmons (Hess 2004:67). Primarily a California-based developer, Eichler placed an emphasis on providing well-crafted, modern residential design for middle-class homebuyers. Lacking in architectural ornament, ‘Eichler houses’ were generally characterized by low and wide front gable roofs, exposed post-and-beam construction, spacious open floor plans, and the use of floor-to-ceiling glass. Taking a cue from Eichler, David Bohannon contracted architects Harwell Hamilton Harris and Edwin A. Wadsworth to design Contemporary and Traditional Ranch model homes that were featured in House Beautiful magazine in 1950. Bohannon’s 1951 tract developments in San Mateo and San Jose were comprised entirely of Contemporary -style Ranch home designed by his in-house architect Mogen Mogenson (Hess 2004:69). Even Cliff May joined in on the Contemporary Ranch movement in 1952 by designing low cost Contemporary style Ranch Houses for suburban markets. Developed along with business partner and architect Chris Choate, his “Cliff May Homes” branded models were built of simple, exposed post and beam construction with ready to assemble materials and retained very little of the romanticized Spanish historicism of his earlier custom houses (Gregory 2008:130-138).
4.4.2 Timber Stringer Bridges
Timber stringer bridges were the standard type of bridge built in many areas of the country in the first half of the twentieth century and during the time when the Southern Heights Bridge was constructed in ca. 1930 (Parsons Brinkerhoff and Engineering and Industrial Heritage 2005). The Southern Heights Timber Stringer Bridge was constructed during the first growth phase within the planned “Southern Heights” community, and was also rehabilitated during a second time of growth within the surrounding neighborhood in the 1950s. The following section describes the history and importance of wood stringer bridges in California and specifically the North Bay.
4.4.2.1 History and Description
“Wood stringer (or beam) bridges are a very old type of design that date back to the origins of bridge building. Ancus Martius’ Roman Pons Sublicius (third to fourth century, B.C.) was a wood pile and stringer structure. In the United States, timber stringer bridges were amongst the earliest built, simple waterway crossings. Long after wood truss bridges had ceased to be competitive with metal truss bridges for use in short spans in the nineteenth century, timber beam bridges were still being built. Because of the structure’s simplicity and readily available material (wood), the timber beam has endured to the present day in the form of rot-resistant timber laminated stringer, or beam, bridges. Today, these structures are built on low-trafficked, rural backcountry roads, private roads, or in national forests and parks.” (Parsons Brinkerhoff and Engineering and Industrial Heritage 2005.)

Engineers in California preferred constructing roadway bridges with steel and concrete in the 1930s through the 1950s; however, timber bridges were still constructed because of the availability of local materials, specifically wood. The timber bridges constructed in California during this time were primarily timber stringer or girder bridges constructed on secondary roadways as utilitarian structures. Central California contains the highest concentration of timber stringer bridges (JRP 2003:59; JRP 2004:20).
Other than the Southern Heights Bridge (Bridge 27C0148), Marin County contains at least three other timber stringer bridges. The Enterprise Concourse over Coyote Creek Tributary (Bridge 27C0129) was constructed in 1950 and the San Geronimo National Golf Course Pedestrian Overcrossing (Bridge 27C0099) was constructed in 1960. Both are listed as Category 5 “Bridge not eligible for NRHP” bridges in the October 2017 Caltrans Historic Bridge Inventory. The Bellam Boulevard Underpass (Bridge 27C0075) was constructed in 1930 and is listed as a Category 4 “Historical Significance not determined” bridge in the October 2017 Caltrans Historic Bridge Inventory. Of all four, the Bellam Boulevard bridge appears to retain the most integrity of design, workmanship, and materials – the aspects important for conveying significance of the timber stringer architectural style.
4.4.2.2 Construction Methods and Materials of Timber Stringer Bridges
According to NPS’s 2004 listed, multiple property, Historic Highway Bridges of California document,
“California's earliest bridges were built using local materials and a minimum of labor. Labor was in short supply in the mountainous areas of California. Often truss and suspension bridges were used to cross rugged terrain. Occasionally, simple timber stringer bridges, incorporated masonry work in piers, abutments, or wingwalls. Here stone from nearby fields or the streambed was utilized.”
Timber stringer (beam) bridges consist of a wood plank deck supported by heavy, square or rectangular, solid-sawn wood beams. Short span timber stringer bridges in the 10- to 30-foot range were and are built in areas that do not carry a high level of traffic and in parks. They are built as approach spans to metal truss, beam or girder bridges or as trestles. The timber beam (stringer) bridge is different from wood trestle bridges related to the type of substructure employed. According to Historic Bridges in North Dakota, whereas the ends of the stringers in a timber stringer bridge rest on a single vertical support constructed of stone, concrete, wood, or steel piles, the stringers of a timber trestle bridge rest on a framework of vertical members joined together with horizontal and diagonal bracing. These differences are important to understanding the construction of these two types of bridges

6.0 FINDINGS AND CONCLUSION
The NRHP and CRHR criteria state that usually a property must be at least 50 years old to be considered for historical significance. This standard is used to ensure that sufficient time has passed to gain an adequate historical perspective of the property’s significance. Six properties (five buildings and one bridge) were identified within the Architectural History APE as being at least 50 years old, or older. All six were evaluated for listing on the NRHP and the CRHR. All six resources appear ineligible for NRHP or CRHR listing (Table 3, 4). Three of these resources are currently listed in a local HRI (Table 4). Details of the evaluation of all six resources are provided on the DPR 523 forms in Appendix C. The following section details the findings of the evaluation.

10 Meyer Road does not appear eligible for listing in the National Register of Historic Places (NRHP) or the California Register of
Historical Resources (CRHR) under any criteria. Although this building is a good example of a Contemporary ranch house, San
Rafael is well-known for containing better examples of Contemporary architecture, including Contemporary Ranch residences
designed by famous architects that specialized in this style including Joseph Eichler, David Beverly Thorne, and Aaron Greene.
Contemporary architecture is widely recognized by its clean lines, geometric planes and surfaces, exposed post and roof beams,
and lack of applied ornamentation. Stone and wood are often used to add warmth, but form and structure are paramount.
Wright-influenced buildings are considered a variant of this style along with examples influenced by Joseph Eichler. The landscape
of the property is also important, as it provides a linkage to the style. 10 Meyer Road consists of key elements of the
Contemporary style that include a shed roof, split-level, warm natural stained wood, and large picture windows that extend the
interior living spaces (see Continuation Sheet, Page 10-13).

B10. Significance (Continued from BSO, page 2)
Contemporary Architectural Style (AKA Contemporary Ranch) (1945 - 1975)
By the late 1940s and early 1950s, builders began to recognize the value of well-designed, affordable
houses in attracting the middle-class consumer, and many began working with architects to develop
new looks for their model homes. Along with the traditional Spanish and Colonial Revival styles of
architecture, the clean lines and simple geometry of the Contemporary Style proved to be well suited to
the low, horizontal massing of the prefabricated Ranch House and became quite popular with fashion-
conscious homebuyers of the period. Architects also began to incorporate modern open floor plans into
their interior designs, often merging the dining, living room, and kitchen areas into one common living
space. Among the most distinctive early Contemporary Style Ranch houses was the ‘Eichler house,’
which was first designed by Stephen Allen and Robert Anshen in 1949 for builder Joseph Eichler and was
later modified by Los Angeles architects A. Quincy Jones and Frederick Emmons (Hess 2004:67).
Primarily a California-based developer, Eichler placed an emphasis on providing well-crafted, modern
residential design for middle-class homebuyers. Lacking in architectural ornament, ‘Eichler houses’ were
generally characterized by low and wide front gable roofs, exposed post-and-beam construction,
spacious open floor plans, and the use of floor-to-ceiling glass. Taking a cue from Eichler, David
Bohannon contracted architects Harwell Hamilton Harris and Edwin A. Wadsworth to design
Contemporary and Traditional Ranch model homes that were featured in House Beautiful magazine in
1950. Bohannon’s 1951 tract developments in San Mateo and San Jose were comprised entirely of
Contemporary Style Ranch home designed by his in-house architect Mogen Mogenson (Hess 2004:69).
Even Cliff May joined in on the Contemporary Ranch movement in 1952, by designing low cost
Contemporary Style Ranch Houses for suburban markets. Developed along with business partner and
architect Chris Choate, his “Cliff May Homes” branded models were built of simple, exposed post-and-
beam construction with ready to assemble materials and retained very little of the romanticized Spanish
historicism of his earlier custom houses (Gregory 2008:130-138).
10 Meyer Road is a good example for Contemporary architecture from the 1950s with its ground-
hugging form that integrates the house to site, and its clean lines, which are features that define this
architectural style.
Historic Context (Continued from BSO, page 2)
PLANNED DEVELOPMENT OF SOUTHERN HEIGHTS
Although 10 Meyer Road was not constructed until 1951, it is important to understand the history of
Southern Heights and the development of the neighborhood. As such the following section is provided

By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of
open land south of downtown San Rafael, which includes the subject property. According to the 1892
Marin County Map, 252-acres of the 549-acres of land owned by Coleman, where the Architectural
History APE is located, was purchased by business partners John William Mackay and James C. Flood.
MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in Nevada that
ultimately produced more than $500 million worth of silver. At some point, the land owned by Flood
and Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion of 252-
acre of land to William L. Courtright and his wife Eloisa Courtright, which included the land along
Southern Heights Boulevard, as well as land east and north of the Southern Heights along present-day
Courtright Road. By 1910, Courtright was selling parcels for development along Southern Heights
Boulevard. An advertisement in the San Francisco Call newspaper, dated May 15, 1910, states,
Advertisement for Southern Heights lot sales, San Francisco Call newspaper, May 15, 1910.
A second advertisement in the San Francisco Call newspaper, dated May 21, 1910, reads,
“SOUTHERN HEIGHTS/HAVE YOUR MANOR HOUSE GROUNDS AROUND YOU AT SAN RAFAEL/OWN

Over the years, neighborhood development included residential houses with a mix of architectural styles
such as the Contemporary house at 10 Meyer Road.
Summary of Land Ownership
The house was built in 1951 by Charles Daglow. Charles was born in 1906 in San Francisco. He attended
college and was a public accountant. He died in 1989 and the property was deeded to his son Don
Daglow, who is the current owner.
Significance Statement:
According to National Register Bulletin No. 15, “How to Apply the National Register Criteria for
Evaluation,” to be eligible for listing in the National Register of Historic Places, a resource must be
significant in state, local or national history, architecture, engineering or culture, and possess integrity of
location, setting, design, material, workmanship, feeling, and association.
In addition, the 1951 house must meet one or more of the four National Register Criteria:
A. Associated with events that have made a significant contribution to the broad patterns of our
history;
B. Associated with the lives of persons significant in our past;
C. Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D. Have yielded, or may be likely to yield, information important in prehistory or history.
10 Meyer Road does not appear to be eligible for listing on the NRHP or CRHR under any criteria.

10 Meyer Road is not significant under Criterion A of the NRHP and Criterion 1 of the CRHR for its
association with an important event in history. Although this residence was associated with the gradual
growth of San Rafael, background research indicates that the building’s contribution to this pattern of
events was not important or exceptional.
10 Meyer Road is not significant under Criterion B of the NRHP and Criterion 2 of the CRHR for its
association with any owners or occupants that appeared to be prominent figures or whose
achievements were considered exceptional. The resource is not associated with a significant person in
national, state, or local history.
10 Meyer Road is not significant under Criterion C of the NRHP and Criterion 3 of the CRHR as a great
example of the Contemporary style; for its type, period, or method of construction; it is not a work of
master; and it does not possess high artistic value. Though the building possesses the general aspects
of Contemporary-style architecture, background research did not identify a master architect or builder
associated with the building. This resources is a good example of Contemporary-style architecture in
San Rafael; however, many other Contemporary-style residences that are better representations of
this style, some of which were designed by famous architects, can be found throughout the city.
Specifically, San Rafael contains more Eichler homes than any other area in Marin County.
10 Meyer Road is not significant under Criterion D of the NRHP and Criterion 4 of the CRHR for having
potential to yield information important to prehistory or history.This evaluation does not include any
potential historical archaeological deposits that may be related to the property.
Integrity
Within the concept of integrity, the National Register Criteria recognize seven aspects or qualities that,
in various combinations, define integrity. To retain historic integrity a property will always possess
several, and usually most, of the aspects. The seven aspects of integrity include location, design,
setting, materials, workmanship, feeling, and association. Integrity of 10 Meyer Road was not assessed
because it was not found eligible under any criteria.
Conclusions
The property at 10 Meyer Road is not significant under any of the National Register nor California
Register Criteria and is not a historic resource under Public Resource Code 5024.

116 Southern Heights Boulevard was previously identified through a local historical resource inventory adopted by the City of
San Rafael; therefore, it is considered a “Historical Resource” in accordance with Section 21084.1 of the California Environmental
Quality Act, Section 15064.5.
116 Southern Heights Boulevard does not appear to be eligible for listing in the National Register of Historic Places (NRHP) or
the California Register of Historical Resources (CRHR). Although 116 Southern Heights Boulevard consists of key elements of the
Dutch Colonial Revival style that include a gambrel roof, dormers, a full-width porch, and wood cladding, the house has been
substantially altered and containss modern elements that compromise its integrity. The term "Colonial Revival" refers to a
rebirth of interest in the early English and Dutch colonial houses of the Atlantic Seaboard. The style was re-introduced the
America at the Philadelphia Exposition of 1876, which marked the centennial of the signing of the Declaration of
Independence. Many of the buildings designed for the Exposition were based on historically significant colonial designs. At
about the same time, several national organizations publicized a series of articles on eighteenth century American architecture,
which appeared in the American Architect and Harpers magazines. The renewed interest in colonial architecture fueled by the
centennial and the exposure of the Colonial Revival style received in national publications helped to make it popular
throughout the country. From about 1890 through 1915, Dutch Colonial Revival architecture was an important style in
residential architecture; however, the Dutch Colonial Revival style is a unique style in the City of San Rafael (see Continuation
Sheet, Page 8-14).

The north elevation consists of clapboard exterior cladding and a second story overhang. There are four
narrow, double-casement windows along the second story. There is a square bay window along the first
story near the northeast elevation and stairs that lead down to the lower ground floor. The ground floor
consists of a small square door, a metal vent, and a door that allows access to the interior of the house.
There is access to the ground floor from this façade; however, access has been blocked with wire, which
is likely to keep animals out.

East Elevation
The east elevation consists of three stories that include a lower elevation ground floor, a first story, and
a second story. The ground floor appears to have a concrete perimeter foundation and plywood siding
with a series of vents. There is a deck that extends out from the first story that is supported by square
columns along this elevation. The current deck is not original to the construction of the house, and was
likely added in the past 30 years, but it is in good condition. There is a berm that abuts the house along
this elevation that likely provides additional support for the house along the steep hillside. The first story
along the east elevation consists of two sets of French doors with a single fixed side transom window
that flanks the doors, and two horizontal rectangular windows. All the windows along the first floor
appear to be wood replacement windows. The second story consists of an extended shed dormer with a
curved, multi-light window that appears to have been cut-out of the center of the dormer, which has
been altered. The window appears to be metal and is not original to the house. There is a wide deck that
extends the length of the house, and a wood and wire railing system.

B10. Significance (Continued from BSO)
Dutch Colonial Revival Style (1890 – 1915)
The “American” Dutch Colonial Revival style was popular in the late nineteenth and early twentieth
centuries, from approximately 1890 to 1915; however, Dutch Colonial architecture was originally based
on the architecture and housing types from the Netherlands dating back to the medieval period. The
style was initially associated with the northeast, and was widely utilized in Pennsylvania and New York
after the Philadelphia Exposition of 1876. The style was found in both urban and rural environments,
though most examples that survived into the late nineteenth century were rural. Dutch Colonial
residential architecture often displays regional variations that reflect available local resources that
includes the use of stone, brick, and wood as building materials. Dutch Colonial Revival architecture is
widely recognized by the gambrel roof, although this roof type was not used exclusively. Gambrel roofs
were often found in New Jersey and the Hudson River Valley early in the colonial period, and later in
New York. The earliest Dutch houses were constructed one-room deep and with steeply pitched roofs.
As homes became larger, these steeply pitched roofs proved vulnerable to wind stresses and
precipitation. As such, some houses featured an upper and lower portion of different pitches. Character-
defining features of the Dutch Colonial Revival style include clapboard or brick exterior cladding, front or
side gambrel roofs, full-width recessed or projecting porches, and simple building forms. They are

typically, one or two stories in height. Roof dormers are typically wide with shed roofs. Classical detailing
is often restrained and includes pediments, columns or pilasters, multi-paned double-hung sash
windows, and fixed shutters. In California, early examples of Dutch Colonial Revival architecture were
often blended with the influences of the Shingle or other Victorian era styles.
Historic Context (Continued from BSO)
PLANNED DEVELOPMENT OF SOUTHERN HEIGHTS
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of
open land south of downtown San Rafael, which includes the land that encompasses the subject
property. According to the 1892 Marin County Map, 252-acres of the 549-acres of land owned by
Coleman, where the property is located, was purchased by business partners John William Mackay and
James C. Flood. MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in
Nevada that ultimately produced more than $500 million worth of silver. At some point, the land owned
by Flood and Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion
of 252-acre of land to William L. Courtright and his wife Eloisa Courtright, which included the land along
Southern Heights Boulevard, as well as land east and north of the Southern Heights along present-day
Courtright Road. By 1910, Courtright was selling parcels for development along Southern Heights
Boulevard. An advertisement in the San Francisco Call newspaper, dated May 15, 1910, states,

Summary of Land Ownership
116 SOuthern Heights Boulevard was constructed by Robert and Emily Boot in 1909. Robert Boot was
born in the city of Nottingham, England on January 10, 1839. His parents were Isaac and Rebecca Sutton
Boot who were Quakers. Robert received his early training at Ackworth High School, from which he
entered an accounting house in his native city where he was employed for two years. During the ensuing
four years he served his apprenticeship in the dry goods business in Hempstead. In 1859, Robert
immigrated to the Toronto, Canada and worked as the manager of Manchester Department, a
wholesale dry goods business. He soon left Canada and came to the U.S. where he engaged in farming in
Baltimore County, Maryland. When the Civil War began, he left the farm and joined the Union Army and
was part of the “commissariat” department that transported provisions to the northern armies. In 1863,
Robert left the U.S. and returned to England, but he soon set sail from London to Auckland, New Zealand.
He lived in Auckland for several years, where he worked in the manufacture and export of Kauri pine
lumber and spar timber. In 1880, Robert and his wife Emily, along with their children moved from

Auckland to Fresno County where they lived for 20 years and owned of tracts of land in Fresno, Kings,
and Tulare Counties. Robert’s extensive knowledge of agriculture led him to become the president of
the largest fruit grower’s organization in the West - the California Raisin Growers Association - from
which he eventually retired. He began his retirement in Alameda, then moved to San Rafael where he
built the house at 116 Southern Heights Boulevard. Robert, his wife Emily, their daughter Margaret
Powers, and her son George A. Powers lived at the property until Robert died in 1934 at the age of 99.

The family sold the property in the late 1930s to Dean Hall and his wife Winifred Hellen Hall. Dean was
a painter who lived in the house with his wife until his death in the early 1950s. Winifred continued to
live in the house until at least 1957.

significant in state, local or national history, architecture, engineering or culture, and possess integrity of
location, setting, design, material, workmanship, feeling, and association.
In addition, 116 Southern Heights Boulevard must meet one or more of the four National Register Criteria:
A.Associated with events that have made a significant contribution to the broad patterns of our
history;
B.Associated with the lives of persons significant in our past;
C.Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D.Have yielded, or may be likely to yield, information important in prehistory or history.
116 Southern Heights Boulevard is not significant under Criterion A of the NRHP and Criterion 1 of the
CRHR for its association with an important event in history. Although this residence was associated with the
gradual growth of San Rafael, background research indicates that the building’s contribution to this pattern
of events was not important or exceptional.
116 Southern Heights Boulevard is not significant under Criterion B of the NRHP and Criterion 2 of the
CRHR for its association with any owners or occupants that appeared to be prominent figures or whose
achievements were considered exceptional. The resource is not associated with a significant person in
national, state, or local history.
116 Southern Heights Boulevard is not significant under Criterion D of the NRHP and Criterion 4 of the
CRHR for having potential to yield information important to prehistory or history.This evaluation does
not include any potential historical archaeological deposits that may be related to the property.

Although 116 Southern Heights Boulevard embodies distinct characteristics of Dutch Colonial Revival
architecture (NRHP Criterion C and CRHR Criterion 3), character defining features such as multi-paned
double-hung sash windows and fixed shutters are not present. Furthermore, a consideration of integrity
is necessary to determine whether 116 Southern Heights Boulevard is eligible for listing in the NRHP or
CRHR.
Integrity
Within the concept of integrity, the National Register Criteria recognize seven aspects or qualities
that, in various combinations, define integrity. To retain historic integrity a property will always
possess several, and usually most, of the aspects. The seven aspects of integrity include location,
design, setting, materials, workmanship, feeling, and association were considered and are listed below.
The historic integrity of location has been retained as the property has not been moved. The integrity of
association also remains as it is still within the Southern Heights neighborhood. The integrity of design,
materials and workmanship has been lost due to the addition of the sunroom with curved windows on
the east elevation, which is out of character for this style and detracts from the character-defining
gambrel roof. Furthermore, the other second-story additions and modifications, including the expansive
modern decking, the window replacements throughout, and the east elevation's doors which appear
modern, compromise the building's integrity of design, workmanship, and materials. The integrity of
feeling and setting of the property has been compromised due to these alterations.
Conclusions
116 Southern Heights Boulevard is significant under Criterion C of the NRHP and Criterion 3 of the
CRHR but does not retain enough historic integrity and therefore is not eligible for the National or
California Registers. 116 Southern Heights Boulevard was previously identified through a local historical
resource inventory adopted by the City of San Rafael; therefore, it is considered a
“Historical Resource” in accordance with Section 21084.1 of the California Environmental Quality Act,
Section 15064.5.

North Elevation
The north elevation consists of two stories over the ground floor “basement” that are clad in a variety of
vertical wood siding and T-11 siding; however, the material is difficult to confirm due to limited access
along the steep east-facing slope. Also, the cladding is not original to the house and was likely modified
within the last 30 years. There is a wooden staircase that allows access to “basement” floor along the
north elevation that includes older sections and newer sections; however, the staircase does not appear
to be original to the house. There are three vinyl windows of varying size along the north elevation and a

East Elevation
The east elevation was not assessible during the field survey and was only viewed from the property at
116 Southern Heights Boulevard. From this limited view, there appears to be two wood decks with
railings, and the exterior is vertical wood cladding. The addition was constructed prior to 1950,
according to Sanborn maps.
Due to limited access, photo was taken from 116 Southern Heights, facing north.
South Elevation
The south elevation consists of what appears to be the original wood shingle cladding. There are two
square-shaped vinyl windows along this elevation and exposed board-formed concrete walls just below
the windows. There is also a concrete retaining wall and stairs that appear over 50 years in age.

B10. Significance (Continued from BSO)
Vernacular Architectural Style
The term vernacular architecture is often referred to as the “architectural language of the people” with
its ethnic, regional and local influences and the product of non-experts. Since the rise of modernism in
the twentieth century, architectural writers have tended to admire what they regarded as traditional
buildings for the immediate relationship between form and function is thought to be designed in response
to the needs of the “local” environment. Vernacular buildings can be residential, industrial or agricultural
(like barns) and usually they are not designed by a famous architect or builder. Vernacular architecture is
also associated with the unique use of materials and conditions of a local environment, but can also be
seen as a ‘reason’ for the design such as the landscape like the mass-produced architecture of a Route 66
gas station.
122 Southern Heights Boulevard has been altered from its original Craftsman style and designed in a
Vernacular style that is sensitive to the surrounding setting of the hillside along Southern Heights
Boulevard and takes advantage of the views along the rear that face the San Francisco Bay.

Historic Context (Continued from BSO)
PLANNED DEVELOPMENT OF SOUTHERN HEIGHTS
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of
open land south of downtown San Rafael, which includes the land where 122 Southern Heights Boulevard
is located. According to the 1892 Marin County Map, 252-acres of the 549-acres of land owned by
Coleman was purchased by business partners John William Mackay and James C. Flood. MacKay and Flood
were two of the “Big Four” that discovered the Comstock Lode in Nevada that ultimately produced more
than $500 million worth of silver. At some point, the land owned by Flood and Mackay was deeded to
James’ son, James L. Flood. In 1907, James L. Flood sold a portion of 252-acre of land to William L.
Courtright and his wife Eloisa Courtright, which included the land along Southern Heights Boulevard, as
well as land east and north of the Southern Heights along present-day Courtright Road. By 1910,
Courtright was selling parcels for development along Southern Heights Boulevard. An advertisement in
the San Francisco Call newspaper, dated May 15, 1910, states,
Advertisement for Southern Heights lot sales, San Francisco Call newspaper, May 15, 1910.
A second advertisement in the San Francisco Call newspaper, dated May 21, 1910, reads,

Summary of Land Ownership
It is not known who owned the house when it was built in 1914; however, by 1920s it was owned by James
W. Milner and his wife Charlotte, both were originally from Iowa. According to the 1930s U.S. Federal
Census, James was a freight agent and Charlotte was a “housewife”. After James died in the late 1930s,
Charlotte continued to live at the house until the late 1940s. The house was purchased in the early 1950s
by John C. and Laura B. Spence. John was born in 1909 in Pennsylvania. He was a barber and owned the
“Central Barber Shop” in San Rafael. Laura was born in Canada and was a “housewife”. After John died in
1980 the house was sold to Edith Rousseau, who appears to have owned it as an investment property
along with Ted Remak. Records show that Ted was the sole owner of the property in 1986. In 1988, Ted
sold the property to Brendan Ankers and Francis (Cotter) Ankers. In 2007, the Ankers sold the house to
Mary Louie Neupauer, and in 2013 the property was sold to Arthur Feidler (who also currently also owns
the property at 136 Southern Heights Boulevard).
Significance Statement:
According to National Register Bulletin No. 15, “How to Apply the National Register Criteria for
Evaluation,” to be eligible for listing in the National Register of Historic Places, a building must be
significant in state, local or national history, architecture, engineering or culture, and possess integrity of
location, setting, design, material, workmanship, feeling, and association.

In addition, 122 Southern Heights Boulevardmust meet one or more of the four National Register Criteria:
A. Associated with events that have made a significant contribution to the broad patterns of our
history; or
B. Associated with the lives of persons significant in our past;
C. Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D. Have yielded, or may be likely to yield, information important in prehistory or history.
The Vernacular style house does not appear to meet any of the four criteria of significance for listing in
the NRHP, or the CRHR.
122 Southern Heights Boulevard is not significant under Criterion A of the NRHP and Criterion 1 of the CRHR for
its association with an important event in history. Although this residence was associated with the gradual
growth of San Rafael, background research indicates that the building’s contribution to this pattern of events was
not important or exceptional.
122 Southern Heights Boulevard is not significant under Criterion B of the NRHP and Criterion 2 of the CRHR for
its association with any owners or occupants that appeared to be prominent figures or whose achievements
were considered exceptional. The resource is not associated with a significant person in national, state, or local
history.
122 Southern Heights Boulevard is not significant under Criterion C of the NRHP and Criterion 3 of the CRHR as a
unique or exemplary vernacular-style house; for its type, period, or method of construction; it is not a work of
master; and it does not possess high artistic value. Background research did not identify a master architect or
builder associated with the building.
122 Southern Heights Boulevard is not significant under Criterion D of the NRHP and Criterion 4 of the CRHR for
having potential to yield information important to prehistory or history.This evaluation does not include any
potential historical archaeological deposits that may be related to the property.
Integrity
Within the concept of integrity, the National Register Criteria recognize seven aspects or qualities that, in various
combinations, define integrity. To retain historic integrity a property will always possess several, and usually
most, of the aspects. The seven aspects of integrity include location, design, setting, materials, workmanship,
feeling, and association. Integrity of 122 Southern Heights Boulevard was not assessed because it was not found
eligible under any criteria.
Conclusions
The property at 122 Southern Heights Boulevard is not significant under any of the NRHP or CRHR Criteria and is
not a historic resource under Public Resource Code 5024.

B10. Significance (Continued from BSO)
Vernacular Architectural Style
The term vernacular architecture is often referred to as the “architectural language of the people” with
its ethnic, regional and local influences and the product of non-experts. Since the rise of modernism in
the twentieth century, architectural writers have tended to admire what they regarded as traditional
buildings for the immediate relationship between form and function is thought to be designed in response
to the needs of the “local” environment. Vernacular buildings can be residential, industrial or agricultural
(like barns) and usually they are not designed by a famous architect or builder. Vernacular architecture is
also associated with the unique use of materials and conditions of a local environment, but can also be
seen as a ‘reason’ for the design like the mass-produced architecture of a Route 66 gas station.
126 Southern Heights Boulevard is designed in a local Vernacular style that is sensitive to the
surrounding setting of the hillside along Southern Heights Boulevard and takes advantage of the views
along rear that face the San Francisco Bay.

PLANNED DEVELOPMENT OF SOUTHERN HEIGHTS
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of
open land south of downtown San Rafael, which includes the land that encompasses the subject property.
According to the 1892 Marin County Map, 252-acres of the 549-acres of land owned by Coleman, where
the property is located, was purchased by business partners John William Mackay and James C. Flood.
MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in Nevada that
ultimately produced more than $500 million worth of silver. At some point, the land owned by Flood and
Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion of 252-acre of
land to William L. Courtright and his wife Eloisa Courtright, which included the subject property,
the land along Southern Heights Boulevard, as well as land east and north of the Southern Heights
along present-day Courtright Road. By 1910, Courtright was selling parcels for development along
Southern Heights Boulevard. An advertisement in the San Francisco Call newspaper, dated May 15, 1910,
states,
Advertisement for Southern Heights lot sales, San Francisco Call newspaper, May 15, 1910.
A second advertisement in the San Francisco Call newspaper, dated May 21, 1910, reads,

Summary of Land Ownership
126 Southern Heights Boulevard was originally owned by Robert Boot and Emily Boot. Robert and Emily
were both born in England and immigrated to the U.S. in 1880. In the 1920s they lived at the house with
their daughter Margaret Powers, and their grandson George Powers. In 1947, the house was sold to Earl
and Marion Turner, who owned the house until 2001. The house was deeded to their children Noel and
Mary after Mary’s death in 2001 and several years later. Mary Turner currently lives at the house.

significant in state, local or national history, architecture, engineering or culture, and possess integrity of
location, setting, design, material, workmanship, feeling, and association.
In addition, the 1914 house and ca. 1950 garage at 126 Southern Heights Boulevard must meet one
or more of the four National Register Criteria:
A.Associated with events that have made a significant contribution to the broad patterns of our
history;
B.Associated with the lives of persons significant in our past;
C.Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D.Have yielded, or may be likely to yield, information important in prehistory or history.
126 Southern Heights Boulevard does not appear to be eligible for listing on the NRHP or the CRHR
under any of the four Criteria.
DPR 523L (Rev. 1/1995)(Word 9/2013)
126 Southern Heights Boulevard is not significant under Criterion A of the NRHP and Criterion 1 of the
CRHR for its association with an important event in history. Although this residence was associated with the
gradual growth of San Rafael, background research indicates that the building’s contribution to this pattern
of events was not important or exceptional.
126 Southern Heights Boulevard is not significant under Criterion B of the NRHP and Criterion 2 of the
CRHR for its association with any owners or occupants that appeared to be prominent figures or whose
achievements were considered exceptional. The resource is not associated with a significant person in
national, state, or local history.
126 Southern Heights Boulevard is not significant under Criterion C of the NRHP and Criterion 3 of the
CRHR as a unique or exemplary vernacular-style house; for its type, period, or method of construction;
it is not a work of master; and it does not possess high artistic value. Background research did not
identify a master architect or builder associated with the building.
126 Southern Heights Boulevard is not significant under Criterion D of the NRHP and Criterion 4 of
the CRHR for having potential to yield information important to prehistory or history. This evaluation
does not include any potential historical archaeological deposits that may be related to the property.

Integrity
Within the concept of integrity, the National Register Criteria recognize seven aspects or qualities
that, in various combinations, define integrity. To retain historic integrity a property will always
possess several, and usually most, of the aspects. The seven aspects of integrity include location,
design, setting, materials, workmanship, feeling, and association. Integrity of 126 Southern Heights
Boulevard was not assessed because it was not found eligible under any criteria.
Conclusions
The property at 126 Southern Heights Boulevard is not significant under any of the NRHP or CRHR
Criteria and is not a historic resource under Public Resource Code 5024.

B10. Significance (Continued from BSO)
Craftsman (1905 - 1930)
Craftsman architecture was the dominant style for smaller houses built throughout the country during
the period from about 1905 until the early 1930s. The style developed from what is known as the
American Arts & Crafts Movement that emerged in the early 20th century in the U.S. as an outgrowth of
the English Arts and Crafts Movement. Its hallmark is a philosophy of honest, simple design expressed in
hand-made creations by skilled craftsmen. While the Movement grew throughout the U.S., California,
especially Southern California, became a particularly strong center for Craftsman design including
architecture, art, and ceramics. The style quickly spread throughout the country by pattern books and
popular magazines. The style faded from favor after the mid-1920s and few were built after 1930s.

The property was then sold to Robert and Jean Jacobs in the early 1960s. According to the 1963 U.S. City
Directory for the City of San Rafael, Robert is listed as the Vice President for “Tom Mc Gruder’s R.
Millbrae” (research did not reveal further information about this company). The property was sold to
the current owner in 2015.
Significance Statement:
According to National Register Bulletin No. 15, “How to Apply the National Register Criteria for
Evaluation,” to be eligible for listing in the National Register of Historic Places, a building must be
significant in state, local or national history, architecture, engineering or culture, and possess integrity of
location, setting, design, material, workmanship, feeling, and association.
In addition, 136 Southern Heights Boulevard must meet one or more of the four National Register Criteria:
A. Associated with events that have made a significant contribution to the broad patterns of our
history;
B. Associated with the lives of persons significant in our past;
C. Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D. Have yielded, or may be likely to yield, information important in prehistory or history.
136 Southern Heights Boulevard does not appear eligible for listing on the NRHP or the CRHR.
Page 10 of 12
136 Southern Heights Boulevard is not significant under Criterion A of the NRHP and Criterion 1 of the
CRHR for its association with an important event in history. Although this residence was associated with the
gradual growth of San Rafael, background research indicates that the building’s contribution to this pattern
of events was not important or exceptional.
136 Southern Heights Boulevard is not significant under Criterion B of the NRHP and Criterion 2 of the
CRHR for its association with any owners or occupants that appeared to be prominent figures or whose
achievements were considered exceptional. The resource is not associated with a significant person in
national, state, or local history.
136 Southern Heights Boulevard is not significant under Criterion C of the NRHP and Criterion 3 of the
CRHR . Though the building possesses some defining characteristics of Crafstman-style architecture, it is
not a great example of a Crafstman style residence. Furthermore, it is not significant for its type, period,
or method of construction; it is not a work of master; and it does not possess high artistic value.
Background research did not identify a master architect or builder associated with the building.

136 Southern Heights Boulevard is not significant under Criterion D of the NRHP and Criterion
4 of the CRHR for having potential to yield information important to prehistory or history. This
evaluation does not include any potential historical archaeological deposits that may be related
to the property.
Integrity
Within the concept of integrity, the National Register Criteria recognize seven aspects or
qualities that, in various combinations, define integrity. To retain historic integrity a property
will always possess several, and usually most, of the aspects. The seven aspects of integrity
include location, design, setting, materials, workmanship, feeling, and association. Integrity of
136 Southern Heights Boulevard was not assessed because it was not found eligible under any
criteria.
Conclusions
The property at 136 Southern Heights Boulevard is not significant under any of the NRHP or
CRHR Criteria and is not a historic resource under Public Resource Code 5024.

*P3a. Description: The Southern Heights Bridge is listed on the Directory of Properties in the Historic Property Date File for Marin
County with a National Register Status code of 7N. The Southern Heights Bridge (bridge) is a one-lane timber stringer bridge that
consists of a rough sawn plank deck with raised runners and wood hand rails. The bridge was constructed in ca. 1930, but was
rehabilitated in 1958 and again in 1981. The bridge has concrete abutments, with concrete piles supporting vertical wooden
members with horizontal and diagonal bracing. There is an abutment, which appears to be a section of the original ca. 1930
structure located below the north end of the bridge, along the west side that measures approximately 3 feet high and 16.5 feet
long and consists of flat aggregated concrete blocks that are approximately 3-4-inches thick and 1-3 feet long. This original
section is adjacent to what is likely a combination of a 1958 abutments and a 1981 abutment. The longitudinal and transverse
wood pile bents appear to be a combination of original, 1958, and 1991 materials; however, the concrete piers that support the
wood piles appear to a combination of those installed in 1958, as well as those installed in 1981. (see Continuation

The structure does not meet the criteria for listing in the National Register of Historic Places (NRHP) or the California Register of
Historical Resources (CRHR) under any criteria.
The structure was first constructed to meet the immediate needs of the growing community of San Rafael, and the type of
construction reflected the local economy of the community. The structure is shown on the 1924 Sanborn Fire Insurance
Map, but a date of ca. 1930 has been applied to conform with this City of San Rafael’s estimated construction date, as it is
unclear if the bridge shown on the 1924 Sanborn map is the same bridge as the existing ca. 1930 bridge. The structure was
rehabilitated in 1958 to meet the increasing needs of the local community, and again in 1981. The Southern Heights Bridge was
economical, easily to erect, and was an efficient structure to build, and these qualities represent a common structural design
and type that is utilitarian and intended for immediate local use. (See Continuation Sheet, Page 3).
Historic Context: Timber stringer bridge design is a very old method of bridge construction that dates to the origins of bridge
building that has endured for centuries and have been used in the development and growth of towns such as San Rafael
mainly due to their simplicity and readily available material (wood). The first records of bridge building in the U.S. are traced to
the early settlements along the East Coast, where they were constructed of basic wood planks with not much support. During
this time, stone bridges were also built, but as the U.S. expanded its territory west, the most common bridge type built was
the timber stringer bridge. Like the Southern Heights Bridge, most timber stringer bridges consisted of rough wood plank
decks that rest on a single vertical support structure, and constructed of a combination of stone, concrete, and wood. By the
early twentieth century, the design of timber stringer bridges was included in the standardized designs of several state
departments of transportation, including California. Other states, such as Montana and Maryland, also developed a
standard design for simple-span timber stringer bridges and as vehicle weights and use increased, creosote-treated timbers
were often utilized. (see Continuation Sheet, Page 3.)

Historic Context
According to the Caltrans Historic Bridges Inventory Update (JRP Historical Consulting, April 2004)1
“In California between the 1920s and the 1930s, “four types of timber bridges were built” that
included the “slab, stringer, truss, and suspension. Douglas fir, grown in California as well as Oregon
and Washington, and California redwood were most commonly used for timber bridges in the state,
although some counties used California red fir and ponderosa pine. The California Division of
Highways typically did not use California red fir or ponderosa pine except when constructing
temporary bridges. During this period, the Division of Highways commonly used creosote pressure-
treated wood, but also used untreated Douglas fir. Most of California’s timber bridges built during
this period are timber stringer or girder bridges. Only a small number of timber slab and timber truss
structures were built during this period. Like other timber bridges, timber trusses, for example, were
largely built by counties in rural areas such as those found in Los Angeles or Humboldt counties.”
Twentieth Century Growth and Development of the City of San Rafael
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of
open land south of downtown San Rafael, which includes the land where the bridge is located.
According to the 1892 Marin County Map, 252-acres of the 549-acres of land owned by Coleman, where
the bridge is located, was purchased by business partners John William Mackay and James C. Flood.
MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in Nevada that
ultimately produced more than $500 million worth of silver. At some point, the land owned by Flood

and Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion of 252-
acre of land to William L. Courtright and his wife Eloisa Courtright, which included the land along
Southern Heights Boulevard, as well as land east and north of the Southern Heights along present-day
Courtright Road. By 1910, Courtright was selling parcels for development along Southern Heights
Boulevard. Below is an advertisement in the San Francisco Call newspaper, dated May 15, 1910,
regarding the Southern Heights Bridge.

the addition of the garage located within APN 013-124-05 and associated with the property at 126
Southern Heights Boulevard. During this time, the lots, which are adjacent and south of the property
located at 116 Southern Heights Boulevard remained undeveloped. However, according to a

The Good Roads Movement
During the late 1890s and early 1900s transportation reform efforts throughout the country took place
and the national “Good Roads Movement” emerged with the goal of improving the condition of local
roads. The popularity of bicycling gave impetus to the movement, and bicyclers aligned with the farmers
in demanding smooth, all-weather roads. It was essentially a rural grass roots movement in which

bicyclers and farmers and their families lobbied for better roads, the farmers to facilitate transporting
their products to market and interacting with their neighbors. States began to heed the public outcry for
better roads and formed statewide “Good Roads” organizations. In Iowa, for example, the Governor
called the first Iowa Good Roads Association meeting in April of 1903, a meeting which signaled a shift in
control of roads from local to state government (21, p. E-15).
The Southern Heights Bridge, although constructed primarily to allow for one-way auto traffic, was also
utilized as a local foot bridge and as a way to get to downtown San Rafael, by avoiding the more heavily
trafficked “D” Street that is below and west of Southern Heights Boulevard (Painter 2015).2
The City of San Rafael constructed the timber stringer bridge along Southern Heights Boulevard in ca.
1930 to also link the developing neighborhoods of Picnic Valley and “Bush’s Tract” and to provide a
faster route to reach downtown San Rafael. During the early twentieth century, the growth of the City of
San Rafael was dependent upon community planning and development enhancements that served the
increased population and communities living further from the downtown. As a part of city
improvements to this planned development along Southern Heights Boulevard, the City of San Rafael set
out to construct access roads to downtown and roads for those who had moved to San Rafael and were
commuting into San Francisco via the ferry. The San Francisco Bay Area ferry services played an
important role in the development of San Rafael and Marin County. The ferry service at one point
constituted the greatest water transit system in the world. From the Gold Rush until the completion of
the Golden Gate Bridge in 1935, ferries provided the only transportation across the Bay to San Rafael.
"In 1930, forty-three ferryboats, the largest number to have ever operated on the bay, carried a total
of forty-seven million passengers and more than six million automobiles from shore to shore. Each
day, fifty to sixty thousand people crossed the bay between San Francisco and Alameda; 25 percent
of them rode in automobiles” (Nancy and Roger Olmsted papers, 1847 -2007).3
The construction of Southern Heights Boulevard provided additional access to residents in the area
and was used to market lots being sold for housing development along Southern Heights, which
included vacation homes for the wealthy and commuters. Several houses are located directly adjacent
to the bridge, and the property located at 122 Southern Heights Boulevards has a front gate that
opens directly onto the bridge, providing a unique association with the bridge and the surrounding
houses. When the Southern Heights Bridge was constructed, timber stringer bridges were the
standardized type of bridge constructed throughout the country. Since it was a lower cost bridge to
build and the easy working characteristics and materials were in plentiful supply, the stringer style
bridge made it a logical choice for many local small bridge projects, including the Southern Heights
Bridge. “Although in the 20th century, concrete and steel replaced wood as the major materials for

By the early 1950s, the Southern Heights Bridge had seen at least 20 years of automobile traffic, and
survived several local earthquakes and local fires. However, in 1954 a fire that destroyed a home along
Southern Heights Boulevard was in-part blamed on the Southern Heights Bridge’s inability to support
the local fire departments ten to twelve-ton trucks. By 1955, the City of San Rafael street
superintendent recommended that the bridge be repaired or be torn down, and closed the bridge to
pedestrian and vehicular traffic until the city could decide the fate of the bridge. In fact, the city
council decided that the amount of vehicular traffic did not warrant any spending for reconstruction
let alone repairing the guard rails (Daily Independent Journal 1954; Daily Independent Journal 1955).5

In 1958, after the bridge was closed for over two years due to it being deemed “unsafe”, the City Council
voted to rehabilitate the bridge. The city awarded the contract to Howard R. Bru construction, who won
the project based on the lowest bid at $21,781 (Daily Independent Journal 1958).6 The work included
putting in concrete piers, replacing defective wooden members of the deck, and rebuilding the
approaches. The bridge was in service another 23 years prior to its second rehabilitated that occurred in
1981. The 1981 rehabilitation included new concrete abutments and additional support. Today, the
existence and technology is more advanced and have made steel and concrete the materials of choice
for constructing bridges.

Bridges, like other infrastructure, are inherently vital to the communities they serve. The Southern
Heights Bridge represents one of the many structures that was important to the growth and
development of San Rafael. The bridge is one of many timber bridges constructed during this time on
secondary roads throughout the North Bay, California, and the United States.
Evaluation:
According to National Register Bulletin No. 15, “How to Apply the National Register Criteria for
Evaluation,” to be eligible for listing in the NRHP, a bridge must be significant in state, local or national
history, architecture, engineering or culture, and possess integrity of location, setting, design, material,
workmanship, feeling, and association.
In addition, the bridge must meet one or more of the four National Register Criteria:
A. Associated with events that have made a significant contribution to the broad patterns of our
history;
B. Associated with the lives of persons significant in our past;
C. Embody the distinctive characteristics of a type, period, or method of construction, or that
represent a significant and distinguishable entity whose components may lack individual
distinction; or
D. Have yielded, or may be likely to yield, information important in prehistory or history.
6 Daily Independent Journal, “Bridge to be Rehabilitated”, Tuesday March 18, 1958
The Southern Heights Bridge is not eligible for listing on the NRHP or CRHR under any criteria.

Within the concept of integrity, the National Register Criteria recognize seven aspects, or qualities that,
in various combinations, define integrity. To retain historic integrity a property will always possess
several, and usually most, of the aspects. The seven aspects of integrity include location, design,
setting, materials, workmanship, feeling, and association. The integrity of this bridge was not assessed
because it was found not eligible for listing on the NRHP or the CRHR under any criteria.
The bridge is not significant under Criterion A of the NRHP or Criterion 1 of the CRHR. The size and type
of the bridge, along with the fact that the City Council at one point decided that the nature of the road
and amount of vehicular traffic did not warrant reconstruction or even repair in 1955, are indicative of a
non-vital roadway. Although this bridge was associated with the gradual growth, planning, and
development of San Rafael, background research indicates that the structure's contribution to this
pattern of events was not important or exceptional and that it is not associated with a specific historic
event that would elevate it in stature.
The bridge is not significant under Criterion B of the NRHP or Criterion 2 of the CRHR for its association
with an important or historically prominent person in national, state, or local history. Background
research did not identify the bridge as being associated with any prominent figure whose
achievements were considered exceptional.
The bridge is not singificant under Criterion C of the NRHP or Criterion 3 of the CRHR for being an
excellent example of a timber stringer bridge. Furthermore, it is not significant for its type, period, or
method of construction; it is not a work of master; and it does not possess high artistic value.
Background research did not identify a master architect or builder associated with the building. This
resource is a good example of a timber stringer bridge in San Rafael; however, there are other timber
stringer bridges throughout the area that have not been altered as substantially as this bridge. The
Bellam Boulevard Underpass (Bridge 27C0075), for example, is a better representation of an early
application of timber stringer bridges in the North Bay.
The bridge is not significant under Criterion D of the NRHP and Criterion 4 of the CRHR for having
potential to yield information important to prehistory or history. This evaluation does not include any
potential historical archaeological deposits that may be related to the property.

SUMMARY OF FINDINGS
The Southern Heights Bridge Replacement BRLO-5043(038) Project (Project) includes the proposed removal of the Southern Heights Bridge (Bridge No. 27CO148) and the construction of a new bridge along Southern Heights Boulevard in the City of San Rafael, Marin County, California. The bridge is being replaced by the City of San Rafael due to structural deficiencies and its overall poor condition, and is eligible for replacement under the Highway Bridge Program (HBP).
The studies for this undertaking were carried out in a manner consistent with the California Department of Transportation’s (Caltrans) regulatory responsibilities under Section 106 of the National Historic Preservation Act (36 CFR Part 800) and pursuant to the January 2014 First Amended Programmatic
Agreement among the Federal Highway Administration, the Advisory Council on Historic Preservation,
the California State Historic Preservation Officer, and the California Department of Transportation
Regarding Compliance with Section 106 of the National Historic Preservation Act (Section 106 PA). The City of San Rafael is the lead California Environmental Quality Act (CEQA) and sponsoring agency of this undertaking.
The Northwest Information Center (NWIC) records search was conducted by Evans & De Shazo on March 30, 2017. No previous studies include the Archaeological APE; within 0.5 miles there are 13 previously conducted cultural resources studies. One study located adjacent to the Archaeological APE did not result in any cultural resources. Pedestrian survey of the Archaeological APE was conducted by Evans & De Shazo, LLC on April 4, 2017. One isolated historic artifact (ISO-01) was identified within the Archaeological APE. The historic-era artifact within the Archaeological APE consists of a 10-pound weight iron dumbbell located on the ground surface under the existing bridge structure approximately 32 feet south of the existing concrete abutment. A photograph of the isolated artifact is shown in Figure 4; the location is shown on the survey coverage map Figures 3.
It is Caltrans' policy to avoid cultural resources whenever possible. Further investigations may be needed if the site[s] cannot be avoided by the project. If buried cultural materials are encountered during construction, it is Caltrans' policy that work stop in the area until a qualified archaeologist can evaluate the nature and significance of the find. Additional survey will be required if the project changes to include areas not previously surveyed.

Ms. Evans has over 17 years of experience in California archaeology. The Study Vicinity Map, Study Location Map, and Survey Coverage Map are included in this report as Figures 1, 2, and 3, respectively.
PROJECT LOCATION AND DESCRIPTION
The proposed Southern Heights Bridge Replacement Project is located in the City of San Rafael, Marin County, California (Figure 1), within Caltrans District 4. The project area includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard situated between Meyer Road and Pearce Road, (Figure 2). This section of Southern Heights Boulevard traverses north/south through a mountainous residential area on the northeast slope of the Southern Heights Ridge, which divides San Rafael from the communities of Larkspur, Greenbrae and Ross, and carries local traffic. The project area is located approximately 0.5 miles south of downtown San Rafael, 0.9-miles west of Highway 101, and 19-mile north of Greenbrae.
Federal Aid Project number BRLO-5043(038) consists of the demolition of the existing bridge (Bridge No. 27CO148) and the construction of a new bridge along Southern Heights Boulevard. The existing bridge is a ca. 1930 one-lane stringer structure with a timber deck supported on timber bents with concrete pedestal footings and reinforced concrete wall abutments, and was rehabilitated in 1958 and again in 1981. The bridge has a width of 9 feet and is 162 feet long with a wood deck and wood railings. The bridge is being replaced due to structural deficiencies and its overall poor condition. The proposed project will replace the existing bridge with a new structure accommodating one 12-foot wide lane and bridge railings, resulting in an approximate bridge width of 15 feet. The new bridge type has not yet been determined, but the structure is expected to be a 100-foot long, multi-span concrete or steel bridge.
The roadway alignment and grade will remain unchanged. The southern roadway approach and retaining wall will begin approximately 20 feet south of the existing southern bridge abutment. The new southern bridge abutment will be shifted north of the driveway to 116 Southern Heights Boulevard. The northern roadway approach will begin 45 feet north of the existing northern bridge abutment. The new northern bridge abutment will be shifted south of the walking access path to 122 Southern Heights Boulevard. A 115-foot long retaining wall will be constructed to the west of the existing retaining wall to allow for the widened bridge. The new retaining wall is expected to be a solider pile wall with steel H-piles and timber lagging with a concrete structural section on the outside face.
No new right-of-way will be required for the new bridge or retaining walls. Temporary construction easements (TCEs) are anticipated on the east and west sides of the bridge to provide construction

access. Utilities, including overhead power and communication and underground water and natural gas, will be relocated with the project. The water and gas lines will be relocated onto the new bridge.
Construction of the bridge will involve excavation for and construction of concrete abutments and piers. The structure will be supported on spread footings or driven/drilled piles. There is no waterway beneath the bridge but a corrugated metal storm drain pipe that will need to be temporarily relocated away from the existing structure base during the construction. Construction of the roadway approaches will involve the removal of existing pavement, retaining walls and fences and the placement of fill material, aggregate base, hot mix asphalt pavement, soldier pile and concrete retaining walls, and new guard rails. Tree removal and removal of other vegetation along the slopes adjacent to the bridge will be necessary for the project.
AREA OF POTENTIAL EFFECT
The Archaeological APE includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard situated between Meyer Road and Pearce Road in the City of San Rafael, Marin County, California. The horizontal Archaeological APE is bounded by the existing right-of-way and includes 274 feet of paved roadway and 162 feet of existing bridge (Bridge No. 27C0148), as well the land under the bridge and on either side of the roadway for 20 feet. This area totals approximately 0.6 acres (see Appendix A for Caltrans-approved Archaeological APE map). The Archaeological APE incorporates the project footprint that consists of the footprint of the existing bridge that is 162 feet long and 9 feet wide, the footprint of the proposed bridge that is 133 feet long and 16 feet wide, and areas not included in the existing right-of-way including a staging area at the north end of the proposed bridge footprint that is 114 feet long and approximately 16 feet wide, and a staging area at the south end of the proposed bridge footprint that is 124 feet long and approximately 17.5 feet wide. No new right-of-way is required and no Federal Lands or Tribal Lands are included in the project APE. Vertical APE is 30 feet below surface, which includes all ground disturbing activities such as removal and installation of bridge abutments, piers, footings, and railings.
SOURCES CONSULTED
SUMMARY OF METHODS AND RESULTS
On March 30, 2017, Sally Evans, M.A., RPA conducted research at the Northwest Information Center (NWIC) of the California Historical Resources Information Systems (CHRIS) in Rohnert Park, CA. (File #16-1500) to obtain information regarding previously recorded historic, prehistoric or ethnographic resources located within a half mile of the Archaeological APE, and to identify areas of previous cultural resource studies within a half mile of the APE (see Appendix B).
The following lists were reviewed:
• National Register of Historic Places
• California Register of Historical Resources
• California Inventory of Historic Resources

• California Historical Landmarks
• California Points of Historical Interest
• Caltrans Historic Highway Bridge Inventory
• California Office of Historic Preservation (OHP) Archaeological Determination of Eligibility
• OHP Directory of Properties in the Historic Property Data File for San Rafael, Marin County
The following maps were reviewed:
• 1858 Plat of the Rancho Punta de Quentin (Matthewson 1858)
• 1871 Sale Map No. 8 of Salt Marsh and Tide Lands Situated in the County of Marin (Middleton 1871)
• 1873 Map of Marin County California (Austin 1873)
• 1892 Official Map of Marin County, California (Dodge 1892)
• 1897 USGS 15-minute Tamalpais topographic map
• 1924 Sanborn Fire Insurance Company Map
• 1924 Sanborn Fire Insurance Company Map update of 1950
• 1941 USGS 15-minute Tamalpais topographic map
• 1951 USGS 15-minute Tamalpais topographic map
Historic and prehistoric references appropriate for the region were also reviewed to provide background information on the prehistory and history of the Archaeological APE region, as well as soils data and other information to identify the potential for buried archaeological resources that may require identification measures beyond a pedestrian archaeological reconnaissance survey.
The record search conducted at the NWIC revealed that the Archaeological APE has not been previously studied for cultural resources. One archaeological resources study was conducted adjacent to the Archaeological APE on the southwest (S-10445, Holman 1988) that did not result in the identification of any archaeological resources.
In total, there have been 13 cultural resource studies conducted within a ½-mile of the Archaeological APE that cover less than 10% of the land within that radius; these are listed in Table 1. The study locations are shown on a map in Appendix B. Two cultural resources have been recorded within 0.5 miles of the Archaeological APE.

0.35 miles north-northwest
There are no California Historical Landmarks, California Points of Historical Interest, or resources listed on the National Register of Historic Places (NRHP), California Register of Historical Resources, or California Inventory of Historic Resources located within or adjacent to the Archaeological APE.
There are two cultural resources recorded on DPR 523 forms within a ½-mile of the Archaeological APE, P-21-000594 and P-21-000645. Virtually nothing is known about prehistoric site P-21-000645 as it was destroyed prior to 1910. P-21-000594 is a multi-component site. The prehistoric component consists of midden soil with lithic tools and debitage, food refuse such as shell and faunal bone, and human remains with associated grave artifacts that include shell beads and pendants. The historic component consists of a historic house (Solomon and Campbell 1996). The site record for P-21-000594 indicates the site lies on an alluvial plain within several hundred meters of San Rafael Creek and close to the historic margin of the San Francisco Bay. Limited excavation of the site revealed that it was occupied for more than 2500 years, based on an analysis of artifacts such as shell beads, pendants, and obsidian projectile points that were associated with as many as 11 separate human burials.
According to the California OHP Archaeological Determination of Eligibility list, neither P-21-000594 nor P-21-000645 has been evaluated to determine their eligibility for listing on the NRHP (OHP 2012).
Similar to P-21-000594 and P-21-000645, prehistoric shell midden sites in the area tend to be situated in close proximity to the historic San Francisco Bay margins and along the creeks that emptied into the bay. The Archaeological APE is located on a ridge 0.2 miles southwest of the historic San Francisco Bay margins, and 0.23 miles west of the nearest creek. Given these factors, the archaeological site sensitivity for prehistoric resources within the Archaeological APE is low to moderate.
A review of historic maps indicate that no buildings were present within the Archaeological APE in the historic period; however, adjacent to the Archaeological APE on the east is a house built in 1909, two houses built in 1914, and a house built in 1971. The archaeological sensitivity for historic resources is moderate due to the presence of buildings adjacent to the Archaeological APE that were present as early as 1907.

SUMMARY OF NATIVE AMERICAN CONSULTATION
The Native American Heritage Commission (NAHC) in Sacramento, California was contacted on April 3, 2017 to request a Sacred Lands Inventory and a list of local Native American organizations and individuals to contact for further information. The results of the Sacred Lands Inventory were received on April 11, 2017 with negative results and two tribal contacts (Souza 2017). A letter was sent to each individual/organization on the Native American Contact List provided by the NAHC on April 19, 2017. The following individuals were contacted:
• Greg Sarris, Chairman, Federated Indian of Graton Rancheria (FIGR)
• Gene Buvelot, FIGR
On May 10, 2017, Buffy McQuillen, the Tribal Heritage Preservation Officer (THPO) with the FIGR, emailed Caltrans District 4 Native American Coordinator Brett Rushing stating,
Thank you for notifying the Federated Indians of Graton Rancheria about Southern Heights
Bridge Replacement Project, San Rafael, Marin County, a project within the Tribe's
Ancestral Territory. We appreciate being notified and will review your project within 10
business days. If you have an immediate request please contact the Tribal Heritage
Preservation Office for assistance by phone at (707) 566-2288 or by email at
thpo@gratonrancheria.com.
On May 22, 2017, Buffy McQuillen, THPO with the FIGR, emailed EDS Principal Archaeologist Sally Evans and Caltrans District 4 Native American Coordinator Brett Rushing stating,
Thank you for the notification regarding the above mentioned project. The project is likely
to impact tribal cultural resources important to the Tribe, with additional concern that
human remains may be nearby. The Tribe would like to participate in the survey phase if it
has not been completed at this time.
On May 24, 2017, Sally Evans responded to Ms. McQuillen, stating,
Thank you for your response regarding the Southern Heights Bridge Project.
Unfortunately, the field survey has been completed already. I have attached a copy of the
draft Archaeological Survey Report (ASR) for your review. Let me know if the Tribe would
like a field visit and I will contact our client (LSA) to arrange that.
No additional communications have been received from Buffy McQuillen or the Federated Indians of Graton Rancheria as of the writing of this report. Native American consultation will continue throughout the duration of this undertaking as needed. All Native American correspondence is attached as Appendix C.

BACKGROUND
ENVIRONMENTAL SETTING
The Archaeological APE is located on the Marin Peninsula, approximately a ½-mile south of downtown San Rafael, 0.67-miles (1078.26 meters [m]) southwest of San Rafael Creek and 2 miles west of the San Rafael Bay portion of the San Francisco Bay. The San Francisco Bay area lies at the approximate midpoint of a mountainous terrain referred to as the Coast Ranges. The Bay itself lies in a forty-mile-long, three to twelve-mile-wide northerly trending structural depression bounded by moderately high north-south trending ridges on the east and west sides. The western ridge stretches south from Mount Tamalpais (elevation, 2,600 feet) on the Marin Peninsula to the Santa Cruz Mountains and is bordered on the west by the Pacific Ocean. The Pacific Ocean connects to the Bay via the Golden Gate, a strait that divides the Marin and San Francisco peninsulas. The eastern ridge is marked by the Berkeley Hills, or “East Bay” hills (elevation 1,900 feet at Volmer Peak), which separate the Bay Shore from the San Ramon and Livermore Valley areas, and the Diablo range, which extends southward from Mount Diablo (elevation, 3730 feet) to Santa Clara Valley (Moratto 1984:219).
Situated at 37° north latitude, the Archaeological APE has a “Mediterranean climate pattern with two distinct seasons: a warm dry period from April to October, followed by a cool, rainy period from November to March” (Okamoto and Wong 2011:45). Annual precipitation ranges from 20-40 inches (Moratto 1984:223), with eighty percent of it occurring between November and March (Okomoto and Wong 2011:46). Air temperatures in January range from 45-55°F, and in July, from 55-65°F near the Bay Shore and up to 15°F higher inland. In the spring and summer months, westerly wind is sucked through the Golden Gate due to these temperature differences (Okamoto and Wong 2011:40). Seasonal weather patterns are also affected by three to four yearlong El Niño Southern Oscillation (ENSO) cycles. An ENSO cycle consists of periods of warmer Pacific Ocean temperatures that increases precipitation (El Niño), followed by periods of cooler-than-average waters and strong ocean upwelling (Okamoto and Wong 2011:47).
GEOARCHAEOLOGICAL SENSITIVITY ANALYSIS
According to Caltrans’ geoarchaeological overview of the region and preliminary soil analysis, the Archaeological APE is not sensitive for surface or buried archaeological deposits based on the Jurassic-Cretaceaous age of the landform which predates human occupation in North America in addition to extensive erosion events associated with the landform (Byrd et al. 2017; Meyer and Rosenthal 2007). The Bay Area landscape has changed dramatically since first human occupation of the region over 10,000 years ago. Towards the end of the Pleistocene, continental ice sheets melted and sea levels rose

rapidly causing landforms which were once suitable for human habitation to become submerged or buried by sediment. This environmental change also formed the San Francisco Bay via inundation of the Franciscan Valley between 11,000 and 8,000 cal BP. Additional environmental changes occurred during the historic-period, corresponding to the arrival of the Spanish. Native vegetation cover was vastly reduced due to agriculture-induced drought and livestock grazing activities creating an erosion susceptible landscape and causing widespread upland erosion, rapid lowland sediment deposition, and deeply cut channels within valleys filled with alluvium (Byrd et al. 2017; Meyer and Rosenthal 2007). Regional to the APE, San Rafael Creek once occupied the lower valley currently occupied by commercial and industrial buildings, westerly adjacent to San Rafael Bay (USGS 1897). The main creek system was located approximately 0.5 miles (804.67 m) away from the APE, but was also accompanied by a salt water marsh, as depicted on the USGS topographic map of Tamalpais, CA (1987). This marsh extended as close as 0.13 miles (209.21 m.).
The area immediately surrounding the Archaeological APE consists of a moderately dense mountainous residential area on the northeast slope of the Southern Heights Ridge, which divides San Rafael from the communities of Larkspur, Greenbrae and Ross. The Southern Heights Ridge reaches an elevation of 540 feet above mean sea level (amsl). The Archaeological APE is situated on the northeast slope of the Ridge at elevations ranging from 230 feet to 312 feet amsl with an average slope of 25.9 percent. As previously stated, the APE is situated on a Jurassic-Cretaceaous-aged (Mesozoic Era) landform consisting of a mélange of sheared and fragmented marine sedimentary and metasedimentary rock associated with the Franciscan Complex (California Geological Survey 2010). In this region, the Franciscan complex is mostly composed of Upper Jurassic-Cretaceous greenstone, chert, sandstone, and shale (Meyer and Rosenthal 2007; Natural Resources Conservation Service [NRCS] 2017). These rock materials associated with the Franciscan complex weathered to form the Tocaloma-McMullin soil complex. In the APE, the soil complex correlates with 30 to 50 percent slopes and provides ideal conditions for vegetation including: California laurel, California live oak, Pacific madrone fern, blackberry bushes, poison oak, tanoak, and annual grasses. The Tocaloma soil series originated from weathered sandstone and shale to form moderately deep, well-draining soil. This deposition is associated with hills that have slopes ranging from 2 to 75 percent. Tacaloma soil typically consists of loam from 0 to 19 inches, followed by very gravelly loam from 19 to 39 inches, underlain by Soft, fractured sandstone bedrock from 39 to 43 inches (NRCS 2003). The McMullin soil series also originated from weathered sandstone and shale as well as various igneous and metamorphic rock to form shallow, well- to- excessive draining soil. This deposition is associated with northward-facing slopes ranging between 1 to 75 percent. In profile, McMullin soil consists of gravelly loam from 0 to 7 inches, and gravelly clay loam from 7 to 14 inches, followed by hardened fractured bedrock starting at 14 inches below ground surface (NRCS 2003).
Furthermore, site sensitivity models by Jack Meyer and Philip Kaijankoski increasingly substantiate and quantify the low sensitivity of the APE. Using “Table 11: Surface Model Weights by Environmental Criteria” and “Table 12: Age-Based Buried Site Potential” presented within the San Francisco Bay-Delta
Regional Context and Research Design for Native American Archaeological Resources, Caltrans District 4. Table 1, below, summarizes the above information relation to the scoring system and sensitivity presented within Table 11 to determine surface site sensitivity.

Based on the cumulative score, the APE has the lowest sensitivity class for surface site sensitivity.
Based on a review of “Table 12: Age-Based Buried Site Potential” presented within the San Francisco
Bay-Delta Regional Context and Research Design for Native American Archaeological Resources, Caltrans
District 4, the APE has the lowest sensitivity class for buried site potential since the age of the landform dates to a Pre-Pleistocene era.
ETHNOGRAPHIC SETTING
Several historically known Native American groups are reported to have lived in territories contiguous to the San Francisco Bay at the time of Spanish contact. Marin County and southern Sonoma County were inhabited by the Coast Miwok, while various groups of Costanoans occupied the San Francisco Peninsula, the South Bay, and the shoreline areas of the East Bay. The area around Mt. Diablo and lands to the north and east were occupied by the Bay and Plains Miwok (Milliken et al. 2007:100).
The Coast Miwok, who inhabited all of Marin County and southern Sonoma County, occupied a territory separate from the other Miwok groups who lived along the western slopes of the Sierra, in the San Joaquin Valley and along the southern shore of Suisun Bay. Linguistically, the Miwok languages belong to the Penutian language stock, which also includes the various Wintun, Patwin, Yokuts, Maidu and Costanoan languages. Within the Coast Miwok territory there was a dialectic division between the Western-Bodega Miwok (Olamentko) and the Southern Marin, or Hookooeko tribe, who spoke the Southern Marin dialect with some linguistic differences between valley and coastal peoples (Kelly 1978:414). Merriam (1907) discusses a third group from the northern area of Southern Marin Valley known as the Lekahtewutko tribe. More recently, Randall Milliken identified the area around San Rafael and Point San Pedro as having been occupied by the Aguasto tribe based on research of mission records. The Richardson Bay area and the surrounding communities of Sausalito, Mill Valley, Belvedere and Tiburon are now recognized as having been occupied by the Huimen tribe, a branch of the Coast Miwok (Goerke 2007:10).

The Coast Miwok practiced a hunting-and-gathering economy and utilized both marine and terrestrial resources. Up to seven species of acorns provided the main vegetable staple, while a number of other nuts, berries, seeds, kelp and seaweed were also relied upon. Black-tailed deer and Tule elk were the primary big game animals, but other mammals and birds, including antelope, bears, sea lions and sea otters, squirrels, rabbits and a variety of inland and shore birds, were also eaten. Shellfish, including abalone, oyster, mussel and clam species, were also important to the diet and an exchange economy, as their shells provided material for both currency and as decorative items. Obsidian was a valuable resource for all prehistoric Californians, who used it to fashion spear points, arrowheads, knives, scrapers, and other cutting implements. The only obsidian source in Marin County is located at Burdell Mountain, but this source was likely “not suitable for tool manufacture, and has not been detected in archaeological collections” (Jackson 1989:82). Instead, the obsidian used by the Coast Miwok comes primarily from the Annadel and Napa Valley sources, located in Sonoma County and Napa County, respectively.
The Coast Miwok divided themselves into small village communities (or tribelets) that made use of designated tracts of land; although larger, permanent settlements are also known to have existed. Small communities moved around within their territory and sometimes across the territories of other groups in order to take advantage of the range of seasonally available subsistence and exchange resources, and to visit places of religious importance. While some locations were used only on occasion for specific purposes, others were used year-round and reflect a variety of economic and ritual activities. Larger semi-permanent and permanent villages consisted of single or multi-family, circular, conical or domed huts (covered with grass or redwood bark) surrounding a large, circular, semi-subterranean ceremonial house, or dance hall. Sweathouses, of similar design to the ceremonial house, were also common. Sociopolitical organization within village communities was non-egalitarian, meaning that differences in status or rank between individuals existed. Most tribelets had a headman or chief, known as the hoipu, and one or two headwomen, called maien. These individuals held high status positions within the group as organizers of various political, social, and religious activities (Slaymaker 1974).
The Coast Miwok had strong spiritual beliefs that were expressed in dance performances, various healing practices, proper behavior, and in their intimate knowledge of the land.
“…communities shared a number of beliefs and practices, reflected in an active spiritual
life, a rich oral literature, a sense of community, a feeling of belonging to the land rather
than being master of it, and a concern about ways to avoid illness and death by
poisoning. Rules for proper behavior acted as the glue that held all this together.
Everyone knew that they must respect not only the land and its animals but also one
another’s property” (Georke 2012:24).
The first European contact with the Coast Miwok appears to have been in 1579, when Sir Francis Drake stopped to repair his ship, the Golden Hinde, somewhere in the Point Reyes vicinity. Sixteen years later, Sebastian Cermeño’s galleon, the San Agustin, ran aground at what is now known as Drake’s Bay and again there is documentation of relations with the indigenous people; and in 1603, Sebastian Vizcaino’s ship landed at Tomales Point. There seems to be no further contact with Europeans until late 1769 when

Portola is said to have “discovered” San Francisco Bay, an event that signaled the beginning of the European conquest of the area. Six years after Portola, on August 5, 1775, Captain Juan Manuel de Ayala sailed the San Carlos into San Francisco Bay and dropped anchor in Richardson Bay near present-day Sausalito. During their forty-four day stay the crew interacted with the Coast Miwok who were “generous with food and gifts, curious about the Spaniards, polite, intelligent and respectful to their elders” (Georke 2007, 2012:42).
Less than a year after the San Carlos sailed into the San Francisco Bay, the Spanish returned to the area to establish a military presidio and mission in San Francisco. Coast Miwok culture became severely disrupted following the establishment of the Mission San Francisco de Asís (1776; also, known as Mission Dolores). The priests at Mission Dolores first focused on converting Native Americans of the San Francisco Peninsula and those in the East Bay, but by 1803 the population of Coast Miwok speakers at Mission Dolores increased significantly. Later, between 1816 and 1817, a large number of Olompali and Petaluma area Coast Miwok were baptized and split between Mission Dolores and Mission San Jose (Milliken 2009). By 1817, Coast Miwok people made up half of the Native American population at Mission Dolores; however, the death rate at Mission Dolores was so high due to cramped and unsanitary conditions and European introduced diseases that a new asistencia, or mission hospital, was established in San Rafael in 1817, and the approximate two hundred Coast Miwok survivors from Mission Dolores were transferred to the new mission outpost (Georke 2012:43). Mission San Rafael was established where the city of San Rafael now lies, at a site of a Coast Miwok village called Nanaguani (Teather 1986:69). Once the mission structures were built to house the military men and their domestic animals and goods, the Native Americans were brought to the mission to work. The Coast Miwok lived outside of the mission structures in their village(s), or what the Spanish called their ranchitos, or "little ranches”. Once brought into the mission system, the Coast Miwok were forced to remain at the missions and provide free labor in exchange for Catholicism.
When Mexico gained its independence from Spain the missions were desecularized; however, the post-mission period was just as devastating to Native Americans as their land was given away to prominent Californio families (California-born people of Mexican heritage) in the Mexican period that raided and terrorized Native American settlements and forced them to work as unpaid laborers. The early American period was even more devastating to Native Americans, as the newly arriving settlers found Native people an impediment to acquiring land, livestock and gold (Georke 2012:54).
In the early years of the twentieth century, the ethnographer S.A. Barrett traveled around the North Bay region interviewing Native Americans and gathering data to record the linguistic boundaries of Native groups and the locations of both active and old village sites (Barrett 1908). His overall purpose was to reconstruct the cultural geography and social relationships of the various native groups that inhabited the region. Although Barrett was able to locate a number of old and current village sites in the central and northern Coast Miwok territory, none were recorded for the territory south of San Rafael. This is in part due to the fact that at the time of Barrett’s study, the remaining Coast Miwok speakers all came from the northern Marin and southern Sonoma County coastal areas and there were no southern Marin Coast Miwok who were knowledgeable about their indigenous culture or willing to share information.

Among the ethnographic “old village” sites reported by Barrett in southeastern Marin County were
Awániwi, located just north of San Rafael. Goerke (2007) talks about the Awániwi as a tribelet located to the north of the territorial boundary of the Huimen, who occupied the southern Marin area. Merriam (1907) and Kelly (1978) reported the presence of a village site in or near Sausalito, called Liwanelowa; and reportedly, the first Coast Miwok people to come into the Mission were from that village (Goerke 2007:14).
PREHISTORIC SETTING
This section provides information derived from the archaeological record of the San Francisco Bay area regarding settlement strategies, levels of social organization, subsistence economies, and food procurement strategies of pre-contact Native populations. It follows a chronology based on the Central California Taxonomic System (CCTS) that has been revised to include two radio-carbon based sequences, known as Scheme D (Groza 2002) and Scheme D2 (Milliken et al. 2007:101), but collapsed into four broad time periods: Early Period (3500 B.C. – 200 B.C.), Middle Period (200 B.C. - 700 A.D.), Middle/Late Period Transition (A.D. 700 – 900), and Late Period (A.D. 900 – 1769). Cultural patterns that emerged in the Bay Area are also described using the pattern-aspect-phase cultural sequence developed by Fredrickson (1973, 1984).
Early Holocene (2000 - 3500 B.C.)
Populations that emerged around the San Francisco during the Early Holocene (8000 – 3500 B.C.) were mobile foragers, characterized by a “Millingstone culture” that used milling slabs and handstones, crude cores and core tools, and various types of large wide-stemmed and leaf-shaped projectile points (Milliken et al. 2007:114; Wiberg 2010:31). Faunal remains indicate that people practiced a broad-spectrum hunting and gathering technique, exploiting acorns and a wide variety of seeds, fish, birds, and mammals, “although robust faunal assemblages are not common” (Hylkema 2002:235). Shellfish were collected, but were not a primary subsistence resource (Moratto 1984:277). Procurement and processing of major plant and animal subsistence resources were performed by all members of a group, including men, women and children (McGuire and Hildebrandt 1994). The settlement pattern is thought to be based on high residential mobility and limited exchange (Wiberg 2010:31).
Early Period (3500 - 200 B.C.)
The Early Period (3500 B.C. - 500 B.C.) marks a shift from a mobile foraging pattern to a sedentary and semisedentary land use pattern along the Bay Shore (Milliken et al. 2007:114-115). This more sedentary way of life seems to have been in response to the adoption of acorns as a primary food source, as well as the availability of a suite of new resources as the San Francisco Bay estuary formed and matured. Populations in the San Francisco Bay region increased during this time, as evident by the establishment of many previously unoccupied sites along the Bay Shore. Social organization became more complex, evidenced by an elaboration in mortuary practices, an increase in ornamental grave associations, regional symbolic integration and the establishment of trade networks. Also, by 1500 B.C., the mortar and pestle initially introduced circa 4000 cal B.C. replaced the use of millingslabs at most sites (Milliken

et al. 2007:115). Cultural patterns that emerge in the San Francisco Bay region during this period include Windmiller in the Delta Region and Lower Berkeley along the Bay Shore.
Stabilization of the Bay water level and formation of marshes around the Bay circa 2500 B.C. coincide with the development of a distinctive cultural pattern along the eastern Bay Shore that was heavily influenced by the Windmiller Pattern of the Delta region. This Lower Berkeley Pattern is recognized by the presence of perforated charmstones, notched and grooved net sinkers, spire-lopped and thick rectangular Olivella beads and distinctive Haliotis pendants (Moratto 1984:259). However, unlike Windmiller Pattern sites, Lower Berkeley Pattern sites are also marked by the presence of numerous mortars and pestles, a greater diversity and number of bone artifacts, and flexed burials that have no burial artifacts or preference for orientation (Milliken et al. 2007:115). The minimal amount of shell compared to faunal bone in Lower Berkeley Pattern components of the Emeryville shellmound (CCO-295) and the West Berkeley site (ALA-307) indicate that shellfish may not have been the primary resource collected during this time (Moratto 1984:277-279; Morgan et al. 1999). While marine resources were utilized, the emphasis appears to have been on terrestrial resources (Hildebrandt and Jones 1991:382).
Middle Period (500 B.C. - A.D. 700) and Middle/Late Period Transition (A.D. 700 – 900)
The Middle Period (500 B.C. - A.D. 700) is marked by a population increase and a greater level of sedentism (Milliken et al. 2007:115-116). Fixed permanent villages used most of the year became dominant along the Bay Shore, including on Belvedere Island. This indicates the establishment of fixed group territories as well (Lightfoot and Luby 2002:276; Wiberg 2010: 31). During this period, population growth led to restricted mobility, which in turn led to resource intensification, increased cooperation and a greater level of social complexity (Milliken et al. 2007:99). In the latter half of the Middle Period (cal A.D. 430 – 700) and the Middle/Late Period Transition (A.D. 700 – 900), a dramatic cultural disruption occurred, marked by changes in shell bead styles, settlement patterns and food resources (Milliken et al. 2007:116).
The Berkeley Pattern, which developed from the preceding Lower Berkeley Pattern, was well established by the Middle Period (Moratto 1984:277). Berkeley Pattern traits typically include tightly flexed burials, with fewer grave offerings and no preference toward orientation. Cremations are occasionally encountered and are associated with more grave goods than flexed burials, a mortuary treatment suggesting differentiation in wealth or status. Burial artifacts typically include Olivella saddle and saucer beads and Haliotis pendants. Berkeley Pattern sites are also characterized by utilitarian objects that include numerous mortars and pestles, which imply greater reliance on nuts and seeds, as well as a highly-developed bone tool industry. New types of bone tools such as the single-barbed bone fish spear indicate a greater dependency on fish and marine mammals like sea otter, seal and sea lion (Elsasser 1978:39; Hildebrandt and Jones 1992: 382). Shellfish collecting was also very important. This is indicated by the deposition of large quantities of shell, mostly mussel, which make up a good portion of shellmound constituents. Hunting is implied by spear and dart-sized projectile points, which were propelled using an atlatl, as well as high frequencies of deer and elk remains (Beardsley 1954; Hildebrandt and Jones 1991:382).

14
Starting at the end of the Middle Period and continuing in the Middle/Late Period Transition many of the Bay Shore sites were abandoned as residential places and then later reused as special-purpose sites in the Late Period (Lightfoot and Luby 2003:277). The reasons postulated for the abandonment of shellmound sites along the Bay include population decline, environmental degradation resulting from drought conditions of the Medieval Climatic Anomaly (MCA) that affected the availability of marine resources, a shift towards greater reliance on acorns rather than shellfish, intrusion of Patwin speaking people into the North Bay, or the return to a semisedentary settlement system whereby year-round occupation of shellmounds gave way to seasonal use of interior localities (Ingram 1998; Lightfoot and Luby 2003:279). Zooarchaeological data suggest that the abandonment of shellmounds as residential places does not coincide with a population decline, as some sites evince continued resource intensification due to overhunting in the Late Period (Broughton 1994).
Late Period (A.D. 900 - 1769)
The Augustine Pattern emerged from the preceding Berkeley Pattern in the Late Period (A.D. 900 - 1769). A variety of diagnostic artifacts make up this cultural expression, including bone harpoons, collared/flanged tobacco pipes, flanged pestles and large “flower pot” mortars, incised bone whistles and tubes, Olivella and clam shell disc beads, “banjo” style Haliotis pendants, and the bow and arrow, inferred by the presence of small, serrated projectile points (Moratto 1984:211-213). The typical burial treatment is in a flexed posture, but cremations and pre-interment grave burning occur. Economically, intensive fishing, hunting and gathering strategies, particularly harvesting acorns and other seeds, characterize Augustine Pattern components. The Augustine Pattern is characterized by more settlements, intensification of trade, greater social and political organization and increased status differentiation and social ranking (Moratto 1984:213).
HISTORIC SETTING
This section outlines the historical chronology of San Rafael with reference to events and themes related to the history of the area from the Spanish period to the later American period.
Spanish Period (1776 – 1821)
After 1776, Spanish activity in the San Francisco Bay Area and in Marin County increased greatly and included the establishment of several missions around the Bay Area (Hoover et al. 1966). The City of San Rafael inherited its name directly from San Rafael Arcangel which was the twentieth mission founded in Alta California on December 14, 1817, in what is now downtown San Rafael, approximately 0.8 miles north of the Archaeological APE. The Prefect of Missions, Father Vincente de Sarria, wrote that San Rafael Arcangel was chosen "in order that this most glorious prince, who in his name expresses the 'healing of God', may care for bodies as well as souls” (Teather 1986:69). Although the mission was established as an asistencia, or mission hospital, to Mission Delores in San Francisco in 1817, it was later upgraded to full mission status in 1822.
Archaeological Survey Report Southern Heights Bridge Replacement Project
15
Mexican Period (1821 – 1848)
In 1821, Mexican won its independence from Spain, which resulted in the decline of the mission system and the removal of the church as the center of authority. The Franciscan missions in Mexico were secularized soon after the revolution, but those in California remained under church control until 1835. This was because California was so far out on the frontier that the church, as the only authority available, would remain in charge for another decade. The law secularizing the missions required that the church relinquish secular control over the neophytes (converted Native Americans), change the missions into pueblos and divide the mission lands, livestock and equipment amongst the resident neophytes. The remaining mission property was to be administered by civil administrators who would oversee the missions until secularization was completed. However, most of the land and property designated for the ex-neophytes were turned into private estates called ranchos, and the Native Americans were driven off. Mission San Rafael was the first mission to be turned over to the Mexican Government in 1833. By 1842, the mission was abandoned and the mission livestock, equipment, and supplies were transferred to General Vallejo, who also had the vines and fruit trees uprooted and replanted on his property. The Mission was sold in 1846 and torn down between 1861 and 1870 (Weber 2006).
The Archaeological APE is situated within land that was part of the Punta de Quentin land grant, an 8,877-acre grant given by Governor Juan B. Alvarado to John B.R. Cooper in 1840 that encompassed the southern portion of San Rafael, the San Quentin peninsula, and the present-day towns of Ross, Kentfield and part of San Anselmo. Cooper married General Mariano Vallejo’s sister Encarnacion in 1827 and became a naturalized Mexican in 1830. Cooper spent little time at his rancho and hired Timothy Murphy of San Rafael to look after his cattle that roamed his rancho land with local Native American supplying the labor force (Mason 1971:48). In 1847, Cooper sold logging rights on the rancho to the U.S. military for payment of $5 per 1,000 board feet cut (Spitz 2006:34).
Early American Period (1848 – 1900)
The 1848 Treaty of Guadalupe Hidalgo marked the end of the Mexican-American war, and in 1850 California was admitted into the United States. Marin County was one of the original 27 counties in the new state of California, and San Rafael served as the county seat with the crumbling mission building serving as the first county courthouse (Teather 1974:66).
Due to the discovery of gold by James W. Marshall at Sutter’s Mill in Coloma, California, the 1850s saw a massive influx of people into California who came to seek their fortune in gold. In addition to massive emigration from the eastern United States, people also came from China, Germany, Chile, Mexico, Ireland, Turkey and France (Harvard University Library Open Collections Program 2017). Once the initial rush (1848-1858) was over, there was a high demand for prime agricultural land, as people realized that money could more easily be made from raising and selling food to satisfy the needs of a rapidly growing population than it could be in the gold fields. As a result, rancho land began to be divided up and sold, or taken over by squatters (Teather 1974). Although the Treaty of Guadalupe Hidalgo provided some protection to those who were granted land during the Mexican Period in that the land grants were to be honored, the Land Act of 1851 required the owners to file a claim with the U.S. District Court. By this

time, Cooper had sold his interests in the Punta de Quentin rancho to Benjamin Buckelew who came to California with his wife Martha. Buckelew founded a watch making and jewelry shop in San Francisco in 1846, and owned and operated a San Francisco newspaper called The Californian in 1847-48 before purchasing the Punta de Quentin rancho in 1850 (Hoover et al. 1966). As the new owner, Buckelew filed a claim for Rancho Punta de Quentin with the Public Land Commission in 1853 and it was confirmed in 1866. Unlike Cooper, Buckelew lived within the rancho, in a house at present-day 111 Redwood Drive in Ross. He also planned a new community development on the San Quentin peninsula called Marin City but ran out of money and, in 1852, sold the 20-acre property at Point San Quentin to the State for construction of San Quentin State Prison (Spitz 2006:34). The 1858 plat of the Punta de Quentin rancho indicates that a few houses, as well as a mill, were present with the rancho land by 1858; however, none were located near the Archaeological APE. Buckelew fell into debt and was forced to sell the rancho
Punta de Quentin to James Ross and John Cowell in 1857 for $30,000. Ross was a Scot who came from Australia to San Francisco in 1848 and made a fortune in the wholesale liquor business. After purchasing the rancho from Buckelew he moved his family into the Buckelew home and set up a trading post called “Ross Landing” (Ross Historical Society 2009).
Although logging in Marin County began during the Spanish period, in 1849 the scale of logging increased dramatically due to a growing demand for lumber in San Francisco (Spitz 2006:49). Redwood, Douglas fir, oaks, laurels, and madrones trees throughout the area were cut and milled at local sawmills, including those located near the Archaeological APE. Munro-Fraser (1880) reports that,
“Magnificent forests were swept away that can never be restored. Fine redwood groves
stretched between San Rafael and San Anselmo. Even the stumps are gone. Great
madrone trees grew on the ridges…Not a tree of them remains…The devastation
wrought through Ross Valley and along the foothill and canyons down to Corte Madera
was nothing short of sacrilege”.
History of San Rafael
In 1844, Governor Micheltorena awarded Timothy Murphy three contiguous ranchos - San Pedro that included portions of present-day San Rafael, Santa Margarita, and Las Gallinas - as a single land grant that totaled 21,678-acres. In 1847, Murphy was appointed the administrator of the Mission San Rafael, acting at an agent for over 1,400 Native Americans still living in and around the mission (Marin History Museum 2008). Murphy utilized the surrounding land for grazing Mission livestock. In 1849, Murphy built an adobe home, at the northeast corner of present-day Fourth and C streets, that was the first private dwelling built in San Rafael (Spitz 2006:38). It was occupied by Don Antonio Osio, while Murphy himself resided in the Mission Buildings (Munro-Frasier 1880:323). The following year the first town lots were laid out, and in 1851 a post office was established. Murphy died in 1853, and his adobe was sold to Timothy Mahon. Mahon either donated or leased the building to the city, and it served as the county courthouse until a new one was constructed in 1872 (Kyle 2002). According to Munro-Frasier (1880:331), in March of 1866 a writer of a local newspaper (the Marin County Journal) published the following recollection of San Rafael,
Archaeological Survey Report Southern Heights Bridge Replacement Project
17
“When we first became a resident of this place, nearly fifteen years ago [in 1851], San
Rafael boasted of ten houses, besides the Mission buildings, one store, one boarding
house, and one whiskey mill. The buildings were all make-shifts—not one substantial
house among them except the residence of the late Timothy Murphy, now owned and
used by the county as a Court-house. No fencing or other improvements were visible
save a corral or two. Now we have three stores, two hotels, two boarding houses, one
restaurant, two livery stables, public school, an academy, a newspaper, telegraph office,
three bootmakers, two blacksmith shops, one harnessmaker, butcher shop, clockmaker,
barber, three layers, a physician, etc. The town contains about seventy-five or eighty
houses, amongst which are some costly residences, with tastefully laid out grounds, the
property of newcomers who have found in our delightful valley and desirable location for
a home.”
San Rafael was officially incorporated in 1874, and at the time of incorporation, it included 160 acres, centered at Fourth and B streets, and 600 residences (Spitz 2006:112). During this time, San Rafael grew slowly due its lack of industry and isolation from San Francisco. This all changed with the coming of the ferry and the railroad in 1870 when the San Rafael & San Quentin (SR&SQ) railroad was established on March 21, 1870, which ran from downtown San Rafael southeast to the ferry terminal at Point San Quentin. The coming of the railroad changed the character of San Rafael from a small isolated town of approximately 841 people in 1870 to approximately 2,276 in 1880.
In 1873, the Archaeological APE was part of a 549-acre property owned by William Tell Coleman, a leading San Rafael citizen and previous U.S. Presidential candidate (Austin 1873; Spitz 2006:101,120). Coleman was born in Kentucky and came to California during the Gold Rush. Coleman earned his fortune by selling tools, wares and other supplies to miners in Sacramento and Placerville before moving to San Francisco in 1850 and starting the William T. Coleman & Company. Coleman was extremely successful in the merchandising business, and was a prominent local figure. In 1851, he founded the Committee of Vigilance in San Francisco, which was established to restore order in San Francisco during a time when vigilante justice was common. In 1856, he established a steamship line between New York and San Francisco, and moved to New York to manage his new business. He came to San Rafael in 1871 and paid $84,000 for 1,100 acres of land that included the 549-acre property that included the Archaeological APE, as well as 915-acres north of the SR&SQ railroad. Coleman hired Golden Gate Park superintendent and civil engineer William Hammond Hall (1846-1934) to lay out the Coleman subdivision and he planted thousands of trees and well-nursed gardens. Coleman was influential in the success of many developments in San Rafael including the Marin County Water & Power Company, promoting the railroad, and he was partner in the Hotel Rafael. By the 1880s, due in part to the efforts of Coleman, San Rafael was an established town with major institutions and business, but it also remained a resort town that catered not only to the wealthy, but working-class travelers as well. Accommodations included luxury hotels, cottages, summer homes, and boarding houses. Growth during this time was support by Hansen & Lund Lumber Yard and Isaac Shaver’s Pioneer Planning Mill & Lumber, Co.
The 1906 earthquake shook San Rafael, jolting many homes off their foundations and knocking over chimneys and rooftops; but the biggest effect of the earthquake was the dramatic increase in population

18
as people fled San Francisco (Spitz 2006). The rail line via ferry continued to be the only way to travel between San Francisco and San Rafael until the construction of the Golden Gate Bridge in 1937, which greatly improved access (Kyle 2002; Spitz 2006).
History of Southern Heights
By the late 1890s and the early 1900s, land speculators and investors were looking to develop parcels of open land south of downtown San Rafael, which includes the land that encompasses the Archaeological APE. According to the 1892 Marin County Map, 252-acres of the 549-acres of land owned by Coleman was purchased by business partners John William Mackay and James C. Flood. MacKay and Flood were two of the “Big Four” that discovered the Comstock Lode in Nevada, which ultimately produced more than $500 million worth of silver. At some point, the land owned by Flood and Mackay was deeded to James’ son, James L. Flood. In 1907, James L. Flood sold a portion of 252-acre of land to William L. Courtright and his wife Eloisa Courtright, which included the Archaeological APE, the land along Southern Heights Boulevard, as well as land east and north of the Southern Heights along present-day Courtright Road. By 1910, Courtright was selling parcels for development along Southern Heights Boulevard. The 1924 Sanborn Fire Insurance map shows the development of Southern Heights Boulevard, the surrounding neighborhood, and the location of a wood plank bridge along Southern Heights Boulevard. The 1950 updated of the 1924 Sanborn Map shows additional development in the area.
FIELD SURVEY METHODS
A field survey of the Archaeological APE was conducted on April 4, 2017 by EDS Principal Archaeologist Sally Evans, M.A., RPA. Ms. Evans holds an M.A. in Cultural Resource Management, is a Registered Professional Archaeologist (RPA No. 29300590), and exceeds the Secretary of the Interior's Professional Qualifications Standards in Archaeology and History, and Caltrans' professional qualification standards as a Principal Investigator for both Prehistoric and Historic Archaeology.
The Archaeological APE was surveyed by walking a linear north/south oriented transect along the east and west sides of both proposed staging areas, and east-west oriented transects under the existing bridge structure that were spaced five feet apart. Most of the proposed staging areas consists of a paved roadway (Southern Heights Boulevard), therefore the ground surface was not visible along the roadway sections; however, the ground survey was visible along both sides of the roadways and under the bridge structure. In total, approximately 73% of ground surface within the APE was inspected for the presence of archaeological resources. This estimate is based on the survey coverage area, calculated in GIS to be approximately 0.44 acres, divided by the total size of the APE (approximately 0.6 acres). Figure 3 shows 1":550' scale survey coverage map. The surveyor looked for the presence of isolated and concentrations of historic and prehistoric artifacts that could constitute an archaeological site.
A Garmin64 Global Positioning Satellite (GPS) system with 1 to 5 meters of accuracy was used to record the survey coverage area. No artifacts were collected during the field survey. Potential isolated artifacts were noted, but not recorded. Isolates are exempt properties that generally do not merit recordation. Their notation in the ASR, without formation recordation, typically exhausts the research value and

19
potential significance of isolates (Volume 2 - Standard Environmental Reference, Chapter 5: Cultural Resources Identification, Page 4:15).
STUDY FINDINGS AND CONCLUSIONS
No potentially significant archaeological resources, including prehistoric or historic archaeological sites, were identified within or adjacent to the Archaeological APE. Additionally, the Archaeological APE is not sensitive for surface or buried archaeological deposits because the landform predates human occupation in North America and has experienced extensive erosion. The undertaking will have low potential to impact either prehistoric or historic-era archaeological resources within the Archaeological APE.
Other Resources
One isolated artifact, referred to as ISO-01, was encountered within and adjacent to the APE. ISO-01 is a 10-pound iron dumbbell that was observed on the ground surface under the existing bridge structure approximately 32 feet south of the concrete abutment (Figure 4).
ISO-01 meets the criteria in Attachment 4 "Properties Except from Evaluation," of the Section 106 PA. Isolated artifacts are exempt properties that generally do not merit recordation (Volume 2 - Standard Environmental Reference, Chapter 5: Cultural Resources Identification, Page 4:15); and do not qualify as a property type eligible for listing on the NRHP or meet the definition of a historical resource under CEQA. Therefore ISO-01 was not recorded on DPR 523 forms. The locations of ISO-01 is shown in Figure 3.
Outside of the Archaeological APE, historic-era artifacts were observed during survey of the Architectural History APE at 116 Southern Heights Boulevard/APN 013-132-03 where the property owner confirmed that an older house had burned down on the property prior to the existing house built in 1971. The historic-era artifacts are outside of the Area of Direct Impact (ADI) and Archaeological APE and will be neither directly nor indirectly affected by the Project. There is no potential for indirect effects because they are located too far away to be impacted by vibration and the Project will not result in increased public access which would put it at risk for vandalism or looting. The historic-era artifacts are located outside of the Archaeological APE that includes all areas that will be directly affected by the Project’s proposed ground disturbing activities. They are located within the Architectural History APE, which is larger than the Archaeological APE because it includes the ADI but also takes into account all adjacent parcels that contain built environment resources that have the potential to be indirectly affected (i.e. visual, vibration, or noise impacts) by the proposed Project. The historic-era artifacts are outside of the Archaeological APE and will not be affected directly or indirectly by the Project; therefore, further consideration of the historic-era artifacts is not warranted for purposes of this Project.
Unidentified Cultural Materials
If previously unidentified cultural materials are unearthed during construction, it is Caltrans' policy that work be halted in that area until a qualified archaeologist can assess the significance of the find.

Additional archaeological survey will be needed if project limits are extended beyond the present survey limits.

Project Description:
Evans & De Shazo, LLC was retained to conduct the necessary cultural resource studies,
including an Archaeological and Historic Property Survey, and Historic Resource Evaluation to
be completed in accordance with Volume 2, Cultural Resources, of the California Department of
Transportation Environmental Handbook, for the Southern Heights Bridge Replacement Project.
The current Southern Heights Bridge (Caltrans Bridge No. 27Co148) is a one-lane stringer
structure with a timber deck supported on timber bents with concrete pedestal footings and
reinforced concrete wall abutments that were constructed in 1981. The bridge is being replaced
due to structural deficiencies and its overall poor condition, and is eligible for replacement
under the Highway Bridge Program (HBP). The California Department of Transportation
(Caltrans), acting as the lead agency under the delegated authority of the Federal Highway
Association (FHWA), is providing the project oversight as federal funds are involved.
Due to the allocation of federal funds, the project is subject to review under the National
Environmental Policy Act (NEPA) and Section 106 of the National Historic Preservation Act
(NHPA). The Caltrans Preliminary Environmental Studies (PES) form for the Southern Heights
Bridge Replacement Project calls for the preparation of an Area of Potential Effect (APE) map, a
Historic Property Survey Report (HPSR), an Archaeological Survey Report (ASR), and potentially
a Historic Resources Evaluation Report (HRER) to fulfill the requirement of determining if the
project will adversely affect historic properties.

RE : Southern Heights Bridge Replacement Proj ect, San Rafael , Marin County
Dear Ms. Evans:
A record search of the Native American Heritage Commission (NAHC) Sacred Lands
File was completed for the area of potential project effect (APE) referenced above with negative
results . Please note that the absence of specific site information in the Sacred Lands File
does not indicate the absence of Native American cultural resources in any APE.
I suggest you contact all of those listed , if they cannot supply information , they might
recommend others with specific knowledge. The list should provide a starting place to locate
areas of potential adverse impact within the APE. By contacting all those on the list, your
organization will be better able to respond to claims of failure to consult. If a response
has not been received within two weeks of notification , the NAHC requests that you follow-up
with a telephone call to ensure that the project information has been received .
If you receive notification of change of addresses and phone numbers from any of these
individuals or groups, please notify me. With your assistance we are able to assure that our
lists contain current information. If you have any questions or need additional information ,
please contact via email: Sharaya.souza@nahc.ca.gov.

April 19,2017 Mr. Gene Buvelot 6400 Redwood Drive, Suite 300 Rohnert Park, CA 94928 File No: 16.01.266 Re: Southern Heights Bride Replacement Project, San Rafael, Marin County, CA FED PROJ #: BRLO-5043(038) Dear Mr. Buvelot: The City of San Rafael, in cooperation with the California Department of Transportation (Caltrans) District 4, is proposing to remove the Southern Heights Bridge (Bridge No. 27Co 148) and construct of a new bridge along Southern Heights Boulevard in the City of San Rafael, Marin County, California. The existing Southern Heights Bridge was constructed in the 1930's as a one-lane stringer structure with a timber deck supported on timber bents with concrete pedestal footings and reinforced concrete wall abutments constructed 1981. The bridge is being replaced by the City clue to its poor condition and structural deficiencies. This bridge is eligible for replacement under the Highway Bridge Program (HBP). The Area of Potential Effect (APE) for archaeology (Archaeological APE) includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard. The Archaeological APE includes 274 feet of paved roadway and 162-feet of existing bridge as \vell the land under the bridge and on either side of the roadway for 20 feet. This area totals approximately 0.6 acres (see Attached APE mah). The City of San Rafael is the sponsoring agency, acting on Caltrans' behalf, for Section 106 and California Enviromnentai Quality Act (CEQA) compliance on this project. As part of State and Federal regulations the City of San Rafael is notifying the Native American community of the proposed project. · Please consider this letter and preliminary project information as the initiation of Section 106 consultation pursuant to the National Historic Preservation Act and as formal notification of a proposed project as required under CEQA, specifically Public Resources Code 21080.3.1 and Chapter 532 Statutes of2014 (i.e. AB 52). Please respond within 30 days, pursuant to PRC 21080.3.l(d) if you would like to consult on this project and provide a designated lead contact person if you have not provided that information to us already. Our records indicate that there are no known archaeological sites recorded within or adjacent to the APE; however, there are two archaeological sites recorded within a half-mile, CA-MRN-313, located 0.35 miles to the northwest, and CA-MRN-626/H, located 0.49 miles to the northwest of the APE. These two sites are shell midden sites situated -+ ----~---CITY OF SAN RAFAEL I 1400 FIFTH AVENUE, SAN RAFAEL, CALIFORNIA 94901 I CITYOFSANRAFAEL.ORG Gary 0. Phillips, Mayor • Kate Colin, Vice Mayor • Maribeth Bushey, Councilmember • John Ga!llblin, Councilmember • Andrew Cuyugan McCullough, Councllmember
Mr. Gene Buvelot April 19, 2017 Page 2 adjacent to the historic San Francisco Bay margins; CA-Mrn-626/H is also known to contain Native American burials, and is a multi-component site that also contains a historic house. A record search of the sacred lands file by the Native American Heritage Commission did not indicate the presence of Native American cultural resources in the immediate APE. We would like to provide you with an opportunity to communicate concerns you might have regarding places within the project area that may be important to your community. We respectfuJiy request your participation in the identification and protection of cultural resources, sacred lands or other heritage sites within the above described project area with the understanding that you or other members of the community might possess specialized knowledge of the area. Since this is a City of San Rafael project, Evans & De Shazo; LLC (EDS) archaeologist Sally Evans, Principal Archaeologist, a consultant representing this local government, will be contacting you. As part of this effo1t, Sally Evans will ask if the Tribe knows of any culturally sensitive locations at, or near, the project location. Our consultant will be inquiring about the Tribe's concerns regarding the proposed project. We recognize the unique government-to-government relationship that the Federally Recognized Tribes hold with the federal government. To complete environmental studies, the City is coordinating with LSA Associates, Inc. (LSA) to conduct studies, provide consultation and prepare documents for the project. EDS has been retained by LSA to provide the necessary Cultural resource studies. Should the Tribe prefer an alternative arrangement on how consultation shall occur, we would be glad to work with you to identify a mutually satisfactory means for including your concerns in the project developnient process. Therefore, if requested by the Tribe, Caltrans, as the acting lead federal agency, would take the lead in this consultation as required under 36 CFR 800.2( c )(2)(ii)(C).

April 19, 2017 Mr. Greg Sarris, Chairperson 6400 Redwood Drive, Suite 300 Rohnert Park, CA 94928 File No: 16.01.266 Re: Southern Heights Bride Replacement Project, San Rafael, Marin County, CA FED PROJ #: BRLO-5043(038) Dear Mr. Sarris: The City of San Rafael, in cooperation with the California Department of Transportation (Caltrans) District 4, is proposing to remove the Southern Heights Bridge (Bridge No. 27Co 148) and construct of a new bridge along Southern Heights Boulevard in the City of San Rafael, Marin County, California. The existing Southern Heights Bridge was constructed in the 1930's as a one-lane stringer structure with a timber deck supported on timber bents with concrete pedestal footings and reinforced concrete wall abutments constructed 1981. The bridge is being replaced by the City due to its poor condition and structural deficiencies. This bridge is eligible for replacement under the Highway Bridge Program (HBP). The Area of Potential Effect (APE) for archaeology (Archaeological APE) includes a 436-foot-long and 60-foot-wide section of Southern Heights Boulevard. The Archaeological APE includes 274 feet of paved roadway and 162-feet of existing bridge as well the land under the bridge and on either side of the roadway for 20 feet. This area totals approximately 0.6 acres (see Attached APE map). The City of San Rafael is the sponsoring agency, acting on Caltrans' behalf, for Section 106 and California Environmental Quality Act (CEQA) compliance on this project. As part of State and Federal regulations the City of San Rafael is notifying the Native American community of the proposed project. Please consider this letter and preliminary project information as the initiation of Section 106 consultation pursuant to the National Historic Preservation Act and as formal notification of a proposed project as required under CEQA, specifically Public Resources Code 21080.3.1 and Chapter 532 Statutes of2014 (i.e. AB 52). Please respond within 30 days, pursuant to PRC 21080.3. l(d) if you would like to consult on this project and provide a designated lead contact person if you have not provided that information to us already. Our records indicate that there are no known archaeological sites recorded within or adjacent to the APE; however, there are two archaeological sites recorded within a half-mile, CA-MRN-313, located 0.35 miles to the northwest, and CA-MRN-626/H, located 0.49 miles to the northwest of the APE. These two sites are shell midden sites situated CITY OF SAN RAFAEL j 1400 FIFTH AVENUE, SAN RAFAEL, CALIFORNIA 94901 I CITYOFSANRAFAEL.ORG Gary 0.

Mr. Greg Sarris April 19, 2017 Page 2 of 3 adjacent to the historic San Francisco Bay margins; CA-Mrn-626/H is also known to contain Native American burials, and is a multi-component site that also contains a historic house. A record search of the sacred lands file by the Native American Heritage Commission did not indicate the presence of Native American cultural resources in the immediate APE. We would like to provide you with an opportunity to conununicate concerns you might have regarding places within the project area that may be important to your community. We respectfully request your participation in the identification and protection of cultural resources, sacred lands or other heritage sites within the above described project area with the understanding that you or other members of the community might possess specialized knowledge of the area. Since this is a City of San Rafael project, Evans & De Shazo, LLC (EDS) archaeologist Sally Evans, Principal Archaeologist, a consultant representing this local government, will be contacting you. As part of this effort, Sally Evans will ask if the Tribe knows of any culturally sensitive locations at, or near, the project location. Our consultant will be inquiring about the Tribe's concerns regarding the proposed project. We recognize the unique government-to-government relationship that the Federally Recognized Tribes hold with the federal government. To complete environmental studies, the City is coordinating with LSA Associates, Inc. (LSA) to conduct studies, provide consultation and prepare documents for the project. EDS has been retained by LSA to provide the necessary Cultural resource studies. Should the Tribe prefer an alternative arrangement on how consultation shall occur, we would be glad to work with you to identify a mutually satisfactory means for including your concerns in the project development process. Therefore, if requested by the Tribe, Caltrans, as the acting lead federal agency, would take the lead in this consultation as required under 36 CFR 800.2( c )(2)(ii)(C). In addition, if at any time during the consultation process the Tribe would like to either involve Caltrans in the consultation process or solely consult with Caltrans as the Federal lead agency, please contact Caltrans District Native American Coordinator Brett Rushing at (510) 286-6336 or via email at brett.rushing@dot.ca.gov. FHW A also understands they may not delegate away their consultation responsibilities. We understand the sensitive nature of the environmental studies with regards to discussions on cultural resources and other environmental impacts which may affect your conununity.

Thank you for your response regarding the Southern Heights Bridge Project. Unfortunately, the field survey has been
completed already. I have attached a copy of the draft Archaeological Survey Report (ASR) for your review. Let me know
if the Tribe would like a field visit and I will contact our client (LSA) to arrange that. I will also incorporate your comments
regarding the Tribe's concerns that human remains may be nearby into the report as well.

Hello Karin –
You are very right to take Category 5 especially with a grain of salt, so good for you checking on this one, and initially
being as the City has it in their historic resources inventory, that would definitely be a red flag! Sometime seemingly
unremarkable bridges might be flagged as part of a larger resource too, but as for what we have here, that are no notes
or no red flags that would alert us to further evaluation. If you think that what the city said seems reasonable, then I
would say you’ve done your due diligence. I do wonder what their original thinking was – maybe better to check if they
have a well‐reasoned inventory form (we especially don’t know about local history or public interest sometimes) or if
they just have the type of minimal form that was more in use a long time ago and does not mean a lot.
Thank you for paying attention and checking on this one anyway!

Subject: bridge eligibility question
Hello Janice,
I hope you are doing well! The bridge called out in the document attached (Bridge #27C0148) is not eligible for listing in
the NRHP because it is a Category 5 bridge. I know we are supposed to take these statuses with a grain of salt (I have
had to evaluate Cat 5 bridges before!), so I was hoping to get your advice on whether we should evaluate this bridge or
not… The City currently has it on their Historic Resources Inventory; but after speaking with them, they do not know why
it was ever included and said they will likely be removing it.
Any suggestions or guidance would be greatly appreciated!
Thanks so much,
Katie

Thank you for providing me the requested information about the Southern Heights Bridge.
The Historic Bridge Foundation has no comment about the replacement of this bridge due to the fact that we do
not have sufficient information on the significance of the bridge or the Section 106 process and any alternatives
that may have been discussed.

The California Department of Transportation (Caltrans), acting as the lead agency under the delegated
authority of the Federal Highway Administration (FHWA), is providing the project oversight as federal
funds are involved. Therefore, the Project is considered an undertaking as defined in 36 CFR §800.16(y)
and subject to review under the 2014 First Amended Programmatic Agreement) Among the Federal
Highway Administration, the Advisory Council on Historic Preservation, the California State Historic
Preservation Officer, and the California Department of Transportation Regarding Compliance with
Section 106 of the National Historic Preservation Act, as it Pertains to the Administration of the Federal‐
Aid Highway Program in California (Section 106 PA).
Here is the additional information you requested:
The proposed Southern Heights Bridge Replacement Project is located in the City of San Rafael, Marin
County, California, within Caltrans District 4. The project area includes a 436‐foot‐long and 60‐foot‐wide
section of Southern Heights Boulevard situated between Meyer Road and Pearce Road. This section of
Southern Heights Boulevard traverses north/south through a mountainous residential area on the
northeast slope of the Southern Heights Ridge, which divides San Rafael from the communities of
Larkspur, Greenbrae and Ross, and carries local traffic. The project area is located approximately 0.5
miles south of downtown San Rafael, 0.9‐miles west of Highway 101, and 19‐mile north of Greenbrae.
The project consists of the demolition of the existing Bridge No. 27CO148 and the construction of a new
bridge along Southern Heights Boulevard.
The existing bridge is a ca. 1930 one‐lane stringer structure with a timber deck supported on timber
bents with concrete pedestal footings and reinforced concrete wall abutments. The concrete piers and
retaining walls, as well as defective wooden deck members were replaced in 1958, and in 1981 the
bridge was again reinforced with concrete wall abutments. The bridge has a width of 9 feet and is 162
feet long with a wood deck and wood railings. The bridge is being replaced due to structural deficiencies
and its overall poor condition. The proposed project will replace the existing bridge with a new structure
accommodating one 12‐foot wide lane and bridge railings, resulting in an approximate bridge width of
15 feet. The new bridge type has not yet been determined, but the structure is expected to be a 100‐
foot long, multi‐span concrete or steel bridge.
The roadway alignment and grade will remain unchanged. The southern roadway approach and
retaining wall will begin approximately 20 feet south of the existing southern bridge abutment. The new
southern bridge abutment will be shifted north of the driveway to 116 Southern Heights. The northern
roadway approach will begin 45 feet north of the existing northern bridge abutment. The new northern
bridge abutment will be shifted south of the walking access path to 122 Southern Heights. A 115‐foot
long retaining wall will be constructed to the west of the existing retaining wall to allow for the widened
bridge. The new retaining wall is expected to be a solider pile wall with steel H‐piles and timber lagging
with a concrete structural section on the outside face.
No new right‐of‐way will be required for the new bridge or retaining walls. Temporary construction
easements (TCEs) are anticipated on the east and west sides of the bridge to provide construction
access. Utilities, including overhead power and communication and underground water and natural gas,
will be relocated. It is not yet clear if the overhead utility relocations will be accommodated within the
existing right‐of‐way or if utility easements will be needed for the overhead piles and wires. The water
and gas lines will be relocated onto the new bridge.
Construction of the bridge will involve excavation for and construction of concrete abutments and piers.
The structure will be supported on cast‐in‐drilled‐hole piles. There is no waterway beneath the bridge,
-
3
but a corrugated metal storm drain pipe that will need to be temporarily relocated away from the
structure during the construction. Construction of the roadway approaches will involve the removal of
existing pavement, retaining walls and fences and the placement of fill material, aggregate base, hot mix
asphalt pavement, soldier pile and concrete retaining walls, and new guard rails. Tree removal and
removal of other vegetation along the slopes adjacent to the bridge will be necessary for the project.
The footprint of the existing bridge is 162 feet long and 9 feet wide, the footprint of the proposed bridge
that is 133 feet long and 16 feet wide, a staging area at the north end of the proposed bridge footprint
that is 114 feet long and approximately 16 feet wide, and a staging area at the south end of the
proposed bridge footprint that is 124 feet long and approximately 17.5 feet wide.
Please notify us the Historic Bridge Foundation has any concerns about the removal and replacement of
this bridge. This is not a request for research; it is solely a request for public input for any concerns that
your organization may have. If you have any questions, please contact me at the same number you used
this afternoon or by replying to this e‐mail.
Happy New Year!

Project Description:
Evans & De Shazo, LLC was retained to conduct the necessary cultural resource studies,
including an Archaeological and Historic Property Survey, and Historic Resource Evaluation to
be completed in accordance with Volume 2, Cultural Resources, of the California Department of
Transportation Environmental Handbook, for the Southern Heights Bridge Replacement Project.
The current Southern Heights Bridge (Caltrans Bridge No. 27Co148) is a one-lane stringer
structure with a timber deck supported on timber bents with concrete pedestal footings and
reinforced concrete wall abutments that were constructed in 1981. The bridge is being replaced
due to structural deficiencies and its overall poor condition, and is eligible for replacement
under the Highway Bridge Program (HBP). The California Department of Transportation
(Caltrans), acting as the lead agency under the delegated authority of the Federal Highway
Association (FHWA), is providing the project oversight as federal funds are involved.
Due to the allocation of federal funds, the project is subject to review under the National
Environmental Policy Act (NEPA) and Section 106 of the National Historic Preservation Act
(NHPA). The Caltrans Preliminary Environmental Studies (PES) form for the Southern Heights
Bridge Replacement Project calls for the preparation of an Area of Potential Effect (APE) map, a
Historic Property Survey Report (HPSR), an Archaeological Survey Report (ASR), and potentially
a Historic Resources Evaluation Report (HRER) to fulfill the requirement of determining if the
project will adversely affect historic properties.

RE : Southern Heights Bridge Replacement Proj ect, San Rafael , Marin County
Dear Ms. Evans:
A record search of the Native American Heritage Commission (NAHC) Sacred Lands
File was completed for the area of potential project effect (APE) referenced above with negative
results . Please note that the absence of specific site information in the Sacred Lands File
does not indicate the absence of Native American cultural resources in any APE.
I suggest you contact all of those listed , if they cannot supply information , they might
recommend others with specific knowledge. The list should provide a starting place to locate
areas of potential adverse impact within the APE. By contacting all those on the list, your
organization will be better able to respond to claims of failure to consult. If a response
has not been received within two weeks of notification , the NAHC requests that you follow-up
with a telephone call to ensure that the project information has been received .
If you receive notification of change of addresses and phone numbers from any of these
individuals or groups, please notify me. With your assistance we are able to assure that our
lists contain current information. If you have any questions or need additional information ,
please contact via email: Sharaya.souza@nahc.ca.gov.

Hi Sally,
Thank you for the notification regarding the above mentioned project. The project is likely to impact tribal cultural
resources important to the Tribe, with additional concern that human remains may be nearby. The Tribe would like to
participate in the survey phase if it has not been completed at this time.

Hi Buffy,
Thank you for your response regarding the Southern Heights Bridge Project. Unfortunately, the field survey has been
completed already. I have attached a copy of the draft Archaeological Survey Report (ASR) for your review. Let me know
if the Tribe would like a field visit and I will contact our client (LSA) to arrange that. I will also incorporate your comments
regarding the Tribe's concerns that human remains may be nearby into the report as well.

MEMORANDUM
DATE: August 17, 2018
TO: Roger Roberts, Property Owner of 223 Southern Heights Blvd.
FROM: LSA for the City of San Rafael
SUBJECT: Southern Heights Blvd. Bridge Replacement Project
Response to Comments emailed to Hunter Young, Senior Civil Engineer, on
August 13, 2018
This memorandum provides responses to comments submitted to the City of San Rafael on Monday,
August 13, 2018 regarding the Southern Heights Blvd. Bridge Replacement Project Initial
Study/Mitigated Negative Declaration (IS/MND). Each comment is indicated in italics with responses
immediately following.
Comment A-1: Section 3.1.2, page 3-4: This section indicates that one street lamp pole may be
replaced and re-located with lighting on a new pole or, alternatively, a low level lighting along the
bridge railing. In either case the objective would be to not diminish night-time views. If a pole
mounted LED light is chosen then it should be well shaded so that its light is entirely focused down. In
this connection, I believe the neighborhood would prefer a low level lighting solution along the
roadway or railing of the new bridge.
Response A-1: The current design intent is for the existing overhead light on the utility pole to be
relocated onto the new utility pole location, and low-level lighting provided on the new bridge
railing, though design details for the low-level lighting have not yet been finalized.
Comment A-2: Section 3.6.2, page 3-34. This section refers to Landslide risk in the Tocoloma and
friable Franciscan Shale Geology of our Southern Heights Ridge. No mention was made of the fact
that a number of landslides have occurred on our ridgeline in past years on both its east and west
facing slopes. This risk is not insignificant, and may actually be the reason/cause for the ravine which
is spanned by the Southern Heights Bridge. I would urge that a geologist be closely involved in
determining the necessary depth, placement, and size of the piers to be constructed to support the
proposed concrete slab bridge being planned.
Response A-2: A licensed geotechnical engineer was retained to perform exploratory field work to
ascertain existing geological conditions and provide recommendations for the depth of the new
bridge pier foundations to support the concrete slab bridge.
Comment A-3: Also, in this connection, this section of the document speaks to the issue of erosion
control and concludes that this risk will be controlled during construction through best management
(W:\16 Streets\16.01 ACTIVE Construction Projects\16.01.266 Southern Heights Bridge Replacement\Documents\Caltrans Docs\Enviromental Docs\IS-MND\3 - Final
Version\LSA Response to Comment Memo.docx) 2
construction practice. No detailed information is provided as to exactly what this would entail,
especially if construction should extend into the rainy season. Our ridge receives approximately the
same amount of annual rainfall (mainly during December, January, and February), that is received by
Kentfield, which averages 50 inches or more, and often includes very heavy rains over short periods
of time. Even if the project is completed in the summer and early fall months there still should be
erosion control measures in place subsequent to the project completion for at least a 3 year period to
allow for re-vegetation to take hold and protect against potential erosion derived from the disturbed
soils from construction beneath and around the bridge.
Response A-3: Per the Caltrans Stormwater Pollution Prevention Plan (SWPPP) Preparation Manual
(October 2016), the SWPPP is a document that addresses water pollution control for a construction
project. The Construction General Permit (CGP) requires that all stormwater discharges associated
with construction activity, where said activity results in soil disturbance of one acre or more of land
area, must be permitted under the CGP and have a fully developed site SWPPP on-site prior to
beginning any soil disturbing activities.
SWPPP templates include a long list of potentially required measures. The CGP requires the
development of a project-specific SWPPP. This means that project design and site requirements are
evaluated alongside potential SWPPP measures. The SWPPP must include the information needed to
demonstrate compliance with all the requirements of the CGP. The SWPPP document must be
prepared by a Qualified SWPPP Developer (QSD). Caltrans specifications require that a Water
Pollution Control Manager (WPC Manager) be responsible for the implementation of a SWPPP. The
WPC Manager must have the same qualifications as a QSD. The SWPPP must be approved by City
prior to start of construction.
Best Management Practices (BMPs) are also a long list of potential requirements which are tailored
to meet the specific design and site details of each project. Refer to the Caltrans BMP Manual for
details. Examples of BMPs for the City of San Rafael can be found here:
https://www.marincounty.org/~/media/files/departments/pw/mcstoppp/development/constructio
n_bmps_pdf.pdf?la=en
A Storm Water Pollution Prevention Plan (SWPPP) will be developed prior to the start of
construction to document all methods to be used prior to, during and after construction to eliminate
storm water pollution (i.e., keeping pollution out of the storm drain system) and reduce erosion and
sedimentation. The SWPPP will incorporate standard BMPs and be in compliance with federal, state
and local regulations.
Comment A-4: Section 3.8 on Environmental Hazards: No mention is made whatsoever of Fire Risk
Management efforts to be included during the Construction period. In this connection, I could not
find any mention anywhere in the document of the estimated period of time for the Construction and
when it would be planned to occur. I assume the project may take anywhere between 3 and 6
months to complete and the time of year that it is done is an important consideration for fire risk in
the dry months on one hand, and if in the winter, then those concomitant storm weather erosion
risks.
(W:\16 Streets\16.01 ACTIVE Construction Projects\16.01.266 Southern Heights Bridge Replacement\Documents\Caltrans Docs\Enviromental Docs\IS-MND\3 - Final
Version\LSA Response to Comment Memo.docx) 3
Response A-4: Fire risk management and mitigation measures are discussed under Threshold H of
Section 3.8, and Mitigation Measure HAZ-2 is included to reduce potential risks associated with fire
hazards. Construction timing and duration is discussed under Project Information, item 8:
Construction may begin as early as winter 2019 and will have a duration of approximately twelve
months.
Comment A-5: Section 3.9.2 speaks to Stormwater Management yet the project description indicates
that there will be a temporary re-location of the corrugated metal drain pipe during construction.
This drain pipe has been in place for at least the entire 37 years that we have lived on Southern
Heights Blvd. I suspect it dates from the 1950’s. It discharges the street runoff down slope to C Street
storm sewers below. It would be useful to know the condition of the existing drainage pipe and its
remaining useful life. If the existing drainage pipe needs to be re-located during construction then
perhaps the pipe should be replaced in its entirety, especially if it is not determined to be in good
condition or has a relatively short remaining useful life.
Response A-5: Any existing storm drain pipes relocated for the purposes of accommodating the new
bridge will be replaced with new storm drain pipes. The condition of and maintenance for the
existing pipes to remain on private property is the responsibility of the property owner. The City of
San Rafael does not have any drainage easements for culverts located on the hillside in the
backyards of the properties located at 10 Meyer Road or 65, 75, or 90 Pleasant Lane.
Comment A-6: Section 3.1.6. Transportation and Traffic. The document indicates that traffic counts
done in the past show that approximately 150 vehicles used the bridge daily. That is interesting and
we can expect at least similar levels of use in the future. However, the document does not address
direction of travel statistics and the speed levels which have been a major concern in the
neighborhood, especially for traffic moving downhill across the bridge. This downhill stretch of
Southern Heights Blvd. while narrow, is fairly straight, and leads to speeds that are often faster than
what is safe. Speed Limit control signs and a Speed Bump at the Northerly downhill end on the
abutment of the bridge would be appropriate and should be considered for inclusion in the project.
Response A-6: After discussing similar comments received from residents who live directly adjacent
to the bridge, the City’s construction plans include installation of new speed limit signs to remind
drivers of the speed limit. In the past, the City has installed speed bumps within public roadways,
however, at the request of the Fire Department and to insure emergency response times are
minimal, Public Works no longer has the practice of installing speed bumps in roadways.
The scope of services of the design team retained by the City does not include a detailed traffic
study to assess the direction of travel of those traversing the bridge, nor to review the speeds at
which they travel. The City’s traffic engineer has previously requested increased enforcement by the
Police Department in the area of Southern Heights Blvd.
Comment A-7: As for the BSA report on Biological Impacts, I would observe that it appears to be
based upon a single site review done in May of 2017. That is fine if that is when the project
construction is to be done during that limited time of year. However, if the actual project
construction is scheduled at another time period then it may not be entirely relevant especially since
it does not include any information or analysis of migratory bird life that passes through our
(W:\16 Streets\16.01 ACTIVE Construction Projects\16.01.266 Southern Heights Bridge Replacement\Documents\Caltrans Docs\Enviromental Docs\IS-MND\3 - Final
Version\LSA Response to Comment Memo.docx) 4
neighborhood in the spring and fall. The BSA recommends that inspection by a biologist be involved
during the construction period in order to minimize impacts on nesting birds in the area, but it does
not opine as to when and what bird nesting may be expected to be encountered, if any.
Response A-7: A single field visit observation was sufficient to determine that the project contains
habitat suitable to nesting birds. Mitigation measure BIO-1 states that if work is to occur during
nesting season (Feb 1 – Aug 31), a qualified biologist shall survey nesting habitat 10 days prior to
start of construction. Additional details as to what further mitigations may apply should that survey
find nesting activities are provided under that mitigation measure.
Comment A-8: I could not find information in this report on how Construction Equipment
Management will be handled during construction so as to minimize in and out neighborhood impacts
particularly for the occupants of the houses adjacent to the bridge site.
Response A-8: Construction staging information is described in Section 3.16.2, under Threshold A.
Construction staging areas are proposed at the north and south ends of the proposed bridge
footprint.
Comment A-9: Lastly, I would observe that the Concept Plan contained in the Appendix includes
removal of an existing fence on the existing retaining wall on the Northern approach the bridge.
Some of that fence along the roadway includes rotted posts. That entire fence along the roadway
should be replaced with something similar in design but The Concept Plan appears to contemplate
the installation of a Guard Rail in place of the existing fence. I would like to suggest that the much
discussed design feature of the bridge railings themselves be carried down slope on the abutment
and along the roadway where the fencing is to be replaced.
Response A-9: The construction drawings for the new bridge include a timber guardrail adjacent to
the existing retaining wall on the northern approach. This guardrail has timber rails supported by
timber posts, backed with steel plates. The intent is for the timber guardrailing to be painted white
to be consistent with existing bridge conditions and yet meet current roadway standards. While the
timber guardrailing will not be identical to the existing bridge railings, it will preserve the character
and feel of the existing bridge.

Prior phases for the project included project initiation, surveying and base mapping, geotechnical investigation, public
outreach, preliminary engineering, environmental technical studies, environmental clearance, right of way services and
final design.
The scope of this amendment request includes:
Analyzing stormwater flows for the proposed storm drains.
Preparation of additional design plans, specifications and estimates (PS&E) to revise the design to address site
restoration requirements associated with agreements in process for the Temporary Construction Easements
(TCE) and requested redesign of the bridge abutment on the north side for the project due to failing retaining
walls in the public right of way along the properties of 122 and 126 Southern Heights Boulevard.
Revising TCE exhibits and descriptions for 4 properties based on comments received from the property owners,
conducting pre and post -construction surveys to reference corner records.
The detailed scope of work for the proposed additional tasks is provided below. A cost proposal for the proposed scope
of work is provided as an attachment.
TASK 1.0 FINAL DESIGN
Drainage Analysis and Memo
Mark Thomas will develop a drainage analysis technical memorandum using the Rational Method and HEC -RAS to analyze
the existing drainage facilities and drainage patterns in the area of the Southern Heights Bridge Replacement Project to
determine the proposed facilities needed to effectively manage roadway and hillside storm water runoff and to
accommodate the proposed improvements. Mark Thomas will map the existing storm drainage system from surveys and
City information. Drainage shed areas will be estimated from supplemental topography and field reviews for detailed
drainage to be conducted in the project area. Tributary areas will be defined, and flow rates calculated for concrete
ditches and pipelines. The calculations will define pipe/culvert lengths, sizes, peak flow velocities, and hydraulic grade
lines.
A Draft and Final Drainage Memo will be prepared to outline existing and proposed storm drain conditions. Mark Thomas
will use the hydraulic analysis and pipe sizing calculations performed as part of the drainage study to design new drainage
systems required for the project. It is assumed there will be no changes to the existing drainage patterns or upgrades to
drainage facilities away from the site. It is also assumed that no additional geotechnical analysis will be required.
Additional PS&L
Mark Thomas will prepare plans, specifications and estimates (PS&E) for the following items:
Replace trees on the west side of Southern Heights Boulevard and restoration of vegetation on slopes beneath
and on the west side of the bridge,

January 7, 2019
• Install a temporary irrigation system to water the new trees during two-year establishment and maintenance
period,
• Install lights in the bridge railing,
• Rehabilitate roadway pavement on Meyer Road west of Southern Heights Boulevard,
• Prepare temporary construction staging plan for widening Southern Heights Boulevard to maintain access to the
driveway at 116 Southern Heights Boulevard during construction,
• Redesign the bridge abutment and wing walls on the north side of the bridge to replace the failing retaining walls
in the public right of way in front of 122 and 126 Southern Heights Boulevard,
• Prepare details for installation of geofoam backfill for the bridge abutments, and
• Redesign the wing wall and retaining wall on the south side of the bridge to lessen construction activities that are
anticipated within the public right of way but that would restrict residential access for the owners of 116 Southern
Heights Boulevard.
Mark Thomas will coordinate directly with the City for direction on the plans. Tree replacements will be based on
recommended tree species and sizes to be provided by the City. The tree planing plan will address Wildland Urban
Interface requirements for the City of San Rafael and County of Marin. Prior to preparation of the plans, Mark Thomas
will conduct one field visit to confirm the limits of the additional design and coordinate with the City staff to obtain copies
of available record maps and as -built drawings.
Quincy Engineering, Inc. (QEI) will assist Mark Thomas in preparing a detailed project construction schedule with
estimated sequencing of project activities and timelines for completion. In addition to the 95% PS&E Constructability
Review scoped in Phase 2, QEI will assist Mark Thomas in developing technical specifications that provide restrictions to
construction activities with the intent of minimizing impacts to residents.
The draft PS&E will be included with the 90% PS&E submittal for the Southern Heights Boulevard Bridge Replacement
Project and submitted to the City for review and comment. We assume there will be one round of comments on the draft
plans after the submittal. Mark Thomas will incorporate review comments by the City on the draft PS&E and resubmit
the Final (signed) PS&E along with any plan red lines to respond and verify the changes have been made and for City use
