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: Project Budget: Funding Sources Allocation Caltrans Highway Bridge Program – Design/Right of Way Funds $825,000 Total Available Funds $825,000 SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 5 Expenses: Expenses Amount Consultant Contract – Design/Right of Way Services $717,844 Estimated Right of Way/Miscellaneous Expenses $107,156 Total Design/Right of Way Expenses $825,000 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. 3.Adopt a resolution adopting the plans and specifications for the Southern Heights Bridge Replacement Project and authorizing the City Clerk to call for bids upon receipt of Caltrans authorization.

(07/18/18) 1-1 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.

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.

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.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a “Potentially Significant Impact” or “Potentially Significant Unless Mitigated” impact on the environment, but at least one effect (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

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. □ □ □ □ □ □ □ □ LSA □ ~ □ □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-2 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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-3 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.

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.

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. Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact Would the project: a. 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? b. Conflict with existing zoning for agricultural use, or a Williamson Act contract? c. 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))? d. Result in the loss of forest land or conversion of forest land to non-forest use? e. Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? 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 □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-6 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, LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-7 • 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.

Potentially Significant Impact Less Than Significant with Mitigation Less Than Significant Impact No Impact Would the project: a. Conflict with or obstruct implementation of the applicable air quality plan? b. Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c. 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)? 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 1 Bay Area Air Quality Management District, 2017. CEQA Air Quality Guidelines.

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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-11 • 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.

No Yes No No Source: LSA (February 2018). 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 use or reducing the maximum idling time to 5 minutes (as required by the LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-13 California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]).

This person shall respond and take corrective action within 48 hours. The BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations. • The City and/or the Project contractor shall require all off-road diesel- powered construction equipment of greater than 50 horsepower used for the Project meet the California Air Resources Board Tier 4 emissions standards. Table 3 shows the proposed Project’s mitigated construction emissions.

No No No No 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.

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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-15 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.

Implementation of the proposed Project would not create objectionable odors affecting a substantial number of people or subject persons to objectionable odors.

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. □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ LSA □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-18 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.

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.

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.

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.

Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? b. Cause a substantial adverse change in the significance of an 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, □ □ □ □ □ □ □ □ LSA □ □ □ □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-26 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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-27 §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, LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-28 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.

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.

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? 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. □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ LSA □ □ □ □ □ □ □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-32 Table 4: Project Site Soils Attribute Tocaloma-McMullin complex, 30 to 50 percent slopes Natural drainage class Well drained Runoff class Tocaloma - medium; McMullin - high Depth to water table More than 80 inches Frequency of flooding None Frequency of ponding None Hydrologic soil group Tocaloma - B; McMullin - D K factor, whole soil .32 Linear Extensibility 1.5 percent Source: NRCS 2018 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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-33 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.

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.

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.

Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the 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 □ □ □ □ LSA □ □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-38 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.

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. 2 San Rafael, City of. 2009. San Rafael Climate Change Action Plan. April 20.

Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b. 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? c.

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.

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.

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.

Violate any water quality standards or waste discharge requirements? b. 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)? c.

Inundation by seiche, tsunami, or mudflow? 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. □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ ~ ~ □ □ □ ~ LSA □ □ □ □ □ □ ~ ~ ~ □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-46 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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-47 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?

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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-49 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.

Land uses surrounding the Project site include residential and open space. The site is not located in the jurisdiction of a habitat conservation plan (HCP) or natural community conservation plan (NCCP) applicable to the Project. 3.10.2 Impact Analysis a. Would the project physically divide an established community? NO IMPACT. The proposed Project would not divide an established community as the Project includes the replacement of an existing bridge along an existing roadway.

The proposed Project is consistent with the City of San Rafael 2020 General Plan and the San Rafael Municipal Code. Therefore, the proposed Project would not conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the Project. No impact would occur. c.

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 the site. Therefore, the proposed Project would not 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 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. □ □ □ □ □ □ LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-54 This page intentionally left blank LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-55 3.12 NOISE Potentially Significant Impact Less Than Significant with Mitigation Less Than Significant Impact No Impact Would the project result in: a.

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 □ □ □ □ □ □ IZI □ □ □ □ □ IZI □ □ □ □ LSA □ □ IZI □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-56 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.

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.

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.

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.

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.

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 LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-62 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 LSA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-63 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.

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?

Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b. Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c. Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? 3.13.1 Environmental Setting The Project site is located in southwestern San Rafael. Proximate land uses include residential and open space. The 2012-2016 American Community Survey 5-Year Estimates indicate a total population of 5,125 in Census Tract 1121 in Marin County, California, where the Project is located (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 a. Would the project induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? LESS THAN SIGNIFICANT IMPACT. The proposed Project would replace an existing bridge within the low-density/hillside residential area of San Rafael. The proposed Project would not directly induce 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? NO IMPACT. Housing units are located adjacent to the existing bridge along Southern Heights Boulevard. Implementation of the proposed Project would not displace these housing units, necessitating the construction of replacement housing elsewhere.

Fire protection? ii. Police protection? iii. Schools? iv. Parks? v. Other public facilities? 3.14.1 Environmental Setting The Project site is located in low-density/hillside residential area of San Rafael and is served by the public services as described below. 3.14.1.1 Fire Protection 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.

Fire protection, Police protection, Schools, and Parks? NO IMPACT. The proposed Project would include the replacement of an existing bridge on Southern Heights Boulevard. The proposed Project would not increase demand for public services, nor degrade the quality of existing public services. During construction, the construction contractor would coordinate with emergency service providers to ensure that construction activities would not impair emergency response times. During operation, the proposed Project would improve circulation on Southern Heights Boulevard by providing a safer bridge that would provide access for emergency service vehicles. The Project would have no impact related to public services including fire and police protection, schools, and parks. v. Other public facilities? NO IMPACT.

Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b. Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? 3.15.1 Environmental Setting The City of San Rafael has 19 parks, maintained by the City’s Community Services Division, for a total of 141 acres of parkland (City of San Rafael 2006). The nearest recreation facility to the Project site is Gerstle Park, located approximately 0.38 miles to the northwest. Gerstle Park includes picnic tables, barbeques, multiple group picnic areas, a basketball court, a tennis court, and a playground. 3.15.2 Impact Analysis a. Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? NO IMPACT. Implementation of the proposed Project would not increase the use of recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated, because the Project would not encourage substantial population growth nor facilitate increased access to nearby parkland and other recreational resources. No impact would occur. b. Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? NO IMPACT. Recreational facilities would not be included as part of the Project, and the expansion of an existing recreational facility would not be required. No impact would occur.

Conflict with adopted policies, plans or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? 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. □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ ~ □ LSA □ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-74 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.

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.

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.

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.

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). □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ □ ~ □ LSA □ □ □ □ ~ S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, C ALIFORNIA I NITIAL S TUDY/MITIGATED N EGATIVE D ECLARATION J ULY 2018 P:\MKT1604\Environ\IS-MND\Southern Heights Final Initial Study_071618.docx (07/18/18) 3-80 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.

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.

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.

Does the project have impacts that are individually limited, but cumulatively considerable? ("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.

NES i 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.

-------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 5 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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ SonomaCounty NapaCounty SolanoCounty MarinCounty ContraCostaCounty SanFranciscoCounty AlamedaCounty £¤101 ÃÃ35 ÃÃ131 ÃÃ221 ÃÃ61 ÃÃ13 ÃÃ4 ÃÃ24 ÃÃ123 ÃÃ29 ÃÃ121 ÃÃ12 ÃÃ37 ÃÃ116 ÃÃ1 §¨¦780 §¨¦980 §¨¦280 §¨¦880 §¨¦580 §¨¦80 MONTEREY MENDOCINO LAKE BUTTE PLUMAS MERCED FRESNO GLENN TEHAMA YOLO SONOMA PLACER NAPACOLUSA EL DORADO STANISLAUSYUBASIERRA S A N B E N I T O NEVAD A SAN JOAQUINSOLANOSA N T A C L A R A CALAVERASM A R I N ALAM E D ASUTTER SACRAMENTOTUOLUMNEAMADO R MADERACONTRA COSTA TRINITY SA N T A C R U Z ^_ ^_ SOURCE: ESRI Imagery (4/2008) I:\MKT1604\GIS\Reports\NESMI\Figure_1_Regional_Loc.mxd (6/27/2017) FIGURE 1 Regional Location 0 2.5 5 MILES LEGEND ^_Project Location Southern Heights Bridge Replacement ProjectCity of San Rafael, Marin County, CaliforniaBridge No. 27C0148; Caltrans District 4Federal Project No. BRLO-5043(038) - • FranciscoBlvd BellamBlvd1st St MissionAve WolfeGradeA uburnStLaurelGroveAve DuBoisStB StLindaro St3rd St2nd St 4th St 5th Ave Lincoln AveHStD StC analStGrandAvePoint S a nPedroRdSirFrancisDrakeBlvdForbesAve Woodland Ave R e d HillAve K e n t A v e Mag n o l i a A v e Irwin St£¤101 §¨¦580 SOURCE: USGS 7.5-Minute Quadrangle (San Rafael) I:\MKT1604\GIS\Reports\NESMI\Figure_2_ProjectVicin_Topo.mxd (6/27/2017) FIGURE 2 0 1000 2000 FEET LEGEND Biological Study Area Southern Heights Bridge Replacement ProjectCity of San Rafael, Marin County, CaliforniaBridge No. 27C0148; Caltrans District 4Federal Project No. BRLO-5043(038)Project Vicinity on Topographic Base C SOURCE: NAIP Aerial Imagery (7/2016) I:\MKT1604\GIS\Reports\NESMI\Figure_3_ProjectVicin_Aerial.mxd (6/27/2017) FIGURE 3LEGEND Biological Study Area Southern Heights Bridge Replacement ProjectCity of San Rafael, Marin County, CaliforniaBridge No. 27C0148; Caltrans District 4Federal Project No. BRLO-5043(038)Project Vicinity on Aerial Base 0 500 1000 FEET D NES 9 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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 10 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) regulates these activities and issues water quality certifications for those activities requiring a 404 permit. In addition, the RWQCB has authority to regulate the discharge of “waste” into waters of the State pursuant to the Porter-Cologne Water Quality Control Act. -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 12 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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 13 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) -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 14 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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ !( !( !( !( !( !( !( !(!( !( !(!(!( !( !( !( !(!( !( !( !(!( !(!(!( !( !( !( !( !(!( !( !( !( !( !( !(!( !( !(!(!( !( !( !(!( !( !( !( !( !(!(!(!( !( !( !( !( !( !( !( !( !( !(!( !( !(!(!(!(!( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !(!(!( !( !(!( !( !( !( !(!(!(!( !(!(!(!( !( !( !( !( !( !( !( !( !( !( !( !( !( !(!( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( !( SOURCE: Basemap - ESRI Street Maps (2017); Mapping - CNDDB (4/2017) I:\MKT1604\GIS\Reports\NESMI\Figure_4_CNDDB_PointOcc.mxd (6/27/2017) FIGURE 4 CNDDB Point Occurrences within a 5-mile Radius LEGEND 5-Mile Radius ^_Biological Study Area CNDDB Occurrences (4/2017) !(California black rail !(California clapper rail !(California giant salamander !(California red-legged frog !(Coastal Terrace Prairie !(Diablo helianthella !(Marin County navarretia !(Marin hesperian !(Marin knotweed !(Marin manzanita !(Marin western flax !(Mt.

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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 18 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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ Southern He igh ts Road SOURCE: Basemap - Marin County Aerial Imagery (6/2014); Mapping - LSA (2017) I:\MKT1604\GIS\Reports\NESMI\Figure_6_Habitat_Comm.mxd (6/27/2017) FIGURE 6 Natural Communities / Land Uses 0 25 50 FEET LEGEND Biological Study Area Natural Communities / Land Uses - (0.36 ac) California Bay Forest - (0.12 ac) Ruderal/Disturbed - (0.07 ac) Developed - (0.11 ac) Landscaped - (0.06 ac) Southern Heights Bridge Replacement ProjectCity of San Rafael, Marin County, CaliforniaBridge No. 27C0148; Caltrans District 4Federal Project No. BRLO-5043(038) ½. \ \ \ \ \ \ \ \ \ • \ \ \ \ \ , \ \ \ \ \ \ \ --,· \ • ,, \ ... \ \ \ \ \ \ :\\ \ \,~~.-~ ., \ r . ..

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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ NES 24 Table 2: Special Status Species and Natural Communities of Special Concern Potentially Occurring in the BSA Scientific Name Common Name Status Habitat Requirements Habitat Present/Absent Rationale Mammals Antrozous pallidus Pallid bat CSC Found in variety of habitats, including grassland, chaparral, woodland, and forest.

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. -------------------------------------------------------------------------------------------------------------------------------------------------------■ Chapter 6 References NES 44 Chapter 6 – References AmphibiaWeb.org.

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.

UNDERTAKING DESCRIPTION AND LOCATION District County Route Post Miles Unit E-FIS Project Number Phase District County Federal Project. Number. (Prefix, Agency Code, Project No.) Location 04 Mrn BRLO-5043(038) City of San Rafael 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 State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 11/29/16] Caltrans, Division of Environmental Analysis.

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 at 126 Southern Heights Boulevard, APN 013-124-07 at 122 Southern Heights Boulevard, APN 013-132-01 at 116 Southern Heights Boulevard, APN 013-132-03 at 108 Southern Heights Boulevard, APN 013-132-04 at 104 Southern Heights Boulevard, APN 012-282-36 at 65 Pleasant Lane, APN 012-282-37 at 75 Pleasant Lane, APN 012- 282-40 at 90 Pleasant Lane, and APN 012-282-17 at 10 Meyer Road. The Architectural History APE includes eleven built-environment resources and totals 3.3 acres.

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 State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 11/29/16] Caltrans, Division of Environmental Analysis.

Page 6 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 State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 11/29/16] Caltrans, Division of Environmental Analysis. Copyright © 2014 State of California. All rights reserved. Alteration to the title and section headings is prohibited. Page 7 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). 5.

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). Additionally, although three of the six resources are currently listed in the San Rafael HRI (116 Southern Heights Blvd [MR #1], 122 Southern Heights Blvd [MR #3], and the Southern Heights Bridge LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, M ARIN C OUNTY, C ALIFORNIA H ISTORICAL R ESOURCES E VALUATION R EPORT T YPE O CTOBER 2017 P:\MKT1604\Tech Studies\Cultural\to Caltrans RTC\Finalized Attachment 3 HRER and Appendices\MKT1604_HRER_FINAL no appendices.docx (01/11/18) ii [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.

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 LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, M ARIN C OUNTY, C ALIFORNIA H ISTORICAL R ESOURCES E VALUATION R EPORT T YPE O CTOBER 2017 P:\MKT1604\Tech Studies\Cultural\to Caltrans RTC\Finalized Attachment 3 HRER and Appendices\MKT1604_HRER_FINAL no appendices.docx (01/11/18) 2 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.

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).

Mary Turner, owner of 126 Southern Heights Boulevard April 4 and April 5, 2017 x Mary advised that she grew up in the house at 126 Southern Heights Boulevard and that the bridge is original and was not replaced in 1981. She stated that her parents Marian and Earl Turner “bought the house in 1947.” Janice Calpo, Caltrans Headquarters Staff Architectural Historian August 10, 2017 X Ms. Calpo stated that there are no notes or red flags that would alert Caltrans to further evaluate Bridge #27CO148. Kitty Henderson, Executive Director, Historic Bridge Foundation (HBF) January 3 and 5, 2018 X X Ms. Henderson said that her organization would like to be included earlier in the planning process when initial discussions of bridge removal occur, so they can be involved in the decision-making process regarding alternatives and/or removal of bridge(s). Ms. Henderson requested additional project information from LSA. LSA provided Ms. Henderson with the information requested through e-mail.

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.

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.

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 1 As depicted on a map adapted by Dewey Livingston on file at Marin County Library, California Room).

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”.

Kent Room, Marin County Library). 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.

COURTRIGHT. Owner” 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.

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 LSA H ISTORICAL R ESOURCES E VALUATION R EPORT O CTOBER 2017 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, M ARIN C OUNTY, C ALIFORNIA P:\MKT1604\Tech Studies\Cultural\to Caltrans RTC\Finalized Attachment 3 HRER and Appendices\MKT1604_HRER_FINAL no appendices.docx (01/11/18) 13 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 LSA S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, M ARIN C OUNTY, C ALIFORNIA H ISTORICAL R ESOURCES E VALUATION R EPORT T YPE O CTOBER 2017 P:\MKT1604\Tech Studies\Cultural\to Caltrans RTC\Finalized Attachment 3 HRER and Appendices\MKT1604_HRER_FINAL no appendices.docx (01/11/18) 14 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.

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.)

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 LSA H ISTORICAL R ESOURCES E VALUATION R EPORT O CTOBER 2017 S OUTHERN H EIGHTS B RIDGE R EPLACEMENT P ROJECT S AN R AFAEL, M ARIN C OUNTY, C ALIFORNIA P:\MKT1604\Tech Studies\Cultural\to Caltrans RTC\Finalized Attachment 3 HRER and Appendices\MKT1604_HRER_FINAL no appendices.docx (01/11/18) 17 5.0 DESCRIPTION OF CULTURAL RESOURCES All six built-environment resources evaluated were determined to be ineligible for listing on the NRHP.

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.

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).

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.

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.

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.

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.

Significance: Theme Period of Significance NA NA Area San Rafael Property Type Residential Applicable Criteria NA 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 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. age of *Resource Name or # (Assigned by recorder) *Recorded by: *Date 9 Continuation 9 Update DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# P-21-001008 DEPARTMENT OF PARKS AND RECREATION HRI # 4902-0277-0000 Trinomial CONTINUATION SHEET Property Name: ____116 Southern Heights Boulevard Page __5___ of _15____ Photo showing the ground floor along the east elevation, facing south.

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 age of *Resource Name or # (Assigned by recorder) *Recorded by: *Date 9 Continuation 9 Update DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# P-21-001008 DEPARTMENT OF PARKS AND RECREATION HRI # 4902-0277-0000 Trinomial CONTINUATION SHEET Property Name: ____116 Southern Heights Boulevard Page __9___ of _15____ 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.

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.

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. Photo of Robert Boot (date unknown) (courtesy of Ancestry.com). 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.

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.

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.

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.

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, “SOUTHERN HEIGHTS/HAVE YOUR MANOR HOUSE GROUNDS AROUND YOU AT SAN RAFAEL/OWN A HANDSOME ACRE HOME DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# P-21-001010 DEPARTMENT OF PARKS AND RECREATION HRI # 4902-0279-0000 Trinomial CONTINUATION SHEET Property Name: ____122 Southern Heights Boulevard Page 10 of 13 Take the daily trip that prolongs your life and makes your home a paradise on earth.

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. ,,, @ z (,..,,,,,,,.,,couRTRIGHT Ro.@f~ "'--~ ........... .

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.

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, “SOUTHERN HEIGHTS/HAVE YOUR MANOR HOUSE GROUNDS AROUND YOU AT SAN RAFAEL/OWN A HANDSOME ACRE HOME DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency DEPARTMENT OF PARKS AND RECREATION Primary# HRI # Trinomial CONTINUATION SHEET Property Name: ____126 Southern Heights Boulevard Page __10___ of _14____ Take the daily trip that prolongs your life and makes your home a paradise on earth.

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.

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.

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.

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.

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.

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. age of *Resource Name or # (Assigned by recorder) *Recorded by: *Date 9 Continuation 9 Update DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# DEPARTMENT OF PARKS AND RECREATION HRI # Trinomial CONTINUATION SHEET Property Name: ____136 Southern Heights Boulevard Page __11___ of _12____ Furthermore, there are much better examples of Craftsman style architecture throughout the county, including the NRHP-listed Erskine B.

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.

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.

Significance: Theme Community Planning and Development Area San Rafael Period of Significance NA Property Type Bridge Applicable Criteria NA 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.

Significance (Continued from BSO) 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.

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.

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 age of *Resource Name or # (Assigned by recorder) *Recorded by: *Date 9 Continuation 9 Update DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# P-21-001009 DEPARTMENT OF PARKS AND RECREATION HRI # 4902-0278-0000 Trinomial CONTINUATION SHEET Property Name: ___Southern Heights Bridge_____________________________________________________________________ Page __10___ of _15___ 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 2 Painter, Diana, 2013.

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 “San Rafael Bridge Closed”, Daily Independent Journal, Monday October 10, 1955.

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. Significance Statement: 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. age of *Resource Name or # (Assigned by recorder) *Recorded by: *Date 9 Continuation 9 Update DPR 523L (Rev. 1/1995)(Word 9/2013) State of California  Natural Resources Agency Primary# P-21-001009 DEPARTMENT OF PARKS AND RECREATION HRI # 4902-0278-0000 Trinomial CONTINUATION SHEET Property Name: ___Southern Heights Bridge_____________________________________________________________________ Page __13__ of _16___ 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.

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. Archaeological Survey Report Southern Heights Bridge Replacement Project 1 INTRODUCTION Sally Evans, M.A., RPA conducted the field survey of the Archaeological APE on April 4, 2017. 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' qualification standards as a Principal Investigator for Prehistoric and Historic Archaeology. 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 2 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 3 • 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.

According to records on file at the NWIC, there are two cultural resources recorded on Department of Parks and Recreation (DPR) 523 forms within a ½-mile of the Archaeological APE; these are listed in Table 2 and depicted on the map in Appendix B. Archaeological Survey Report Southern Heights Bridge Replacement Project 5 TABLE 2: CULTURAL RESOURCES PREVIOUSLY RECORDED WITHIN A ½-MILE OF THE ARCHAEOLOGICAL APE. Primary No. Trinomial No. Description Proximity to Archaeological APE P-21-000594 CA-MRN-626/H 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). 0.49 miles north-northwest P-21-000645 CA-MRN-313 Reported general location of a prehistoric Native American “shell-ground” site that appears to have been destroyed prior to 1910 (Nelson 1910). 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. Archaeological Survey Report Southern Heights Bridge Replacement Project 6 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. SUMMARY OF HISTORICAL ORGANIZATION CONSULTATION Kitty Henderson, Executive Director of the Historic Bridge Foundation, was called on January 3, 2017 and a voicemail was left for her, specifying the bridge to be removed, location, and providing callback Archaeological Survey Report Southern Heights Bridge Replacement Project 7 information. Ms. Henderson returned the call on January 3, 2017 and requested additional information about the project and bridge. The information was e-mailed to her on January 3, 2017 with an invitation to reply if the Historic Bridge Foundation has any concerns or input. Ms. Henderson called on January 5, 2017 at 8:15 AM and left a message saying she would call later that day. At 11:30 LSA returned her phone call and left a voicemail acknowledging her earlier call and expecting her call back. No response has been received to date. Correspondence with Ms. Henderson is included in 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 8 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. Archaeological Survey Report Southern Heights Bridge Replacement Project 9 Table 1: Surface Site Sensitivity Environmental Theme Data Presented Score Slope (%) 25.9 percent 0 Distance to Historic- Era Streams (meters) 804.67 m 0.33 Distance to Confluence of Historic-Era Shoreline 2,639.32 m 0 Cumulative Score: 0.33 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). Archaeological Survey Report Southern Heights Bridge Replacement Project 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 11 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. Archaeological Survey Report Southern Heights Bridge Replacement Project 12 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 13 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). Archaeological Survey Report Southern Heights Bridge Replacement Project 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 16 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 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 Archaeological Survey Report Southern Heights Bridge Replacement Project 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. Archaeological Survey Report Southern Heights Bridge Replacement Project 20 Additional archaeological survey will be needed if project limits are extended beyond the present survey limits.

USGS Quadrangle 7.5’ USGS San Rafael quadrangle (1993) Township 1 North Range 6 West Section(s) 4 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. • Ev ANS t'!l DE SHAZO LLC RCHAEOLOGY (9 HISTORIC PRESER\~ATION I l 6876 Sebastopol Avenue Sebastopol, CA 95472 (707) 812-7400 | www.evans-deshazo.com We are contacting you to request a Sacred Sites inventory for the Project Area (APE map attached) and a list of Native Americans to contact for further information.

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!     Rhea Sanchez, RPA 17075 | Cultural Resources Manager  LSA | 201 Creekside Ridge Court, Suite 250  Roseville, CA 95678  – – – – – – – – – – –  916‐772‐7450 Tel  Website  Attachment 5: Native American Consultation Correspondence Sacred Lands Inventory Request Letter to Native American Heritage Commission (NAHC) NAHC Letter with Results of Sacred Lands Inventory and Native American Contact List Letters to Native American Individuals/Organizations on the NAHC Native American Contact List to initiate consultation Correspondence from Federated Indians of Graton Rancheria (FIGR) 6876 Sebastopol Avenue Sebastopol, CA 95472 (707) 812-7400 | www.evans-deshazo.com March 31, 2017 Native American Heritage Commission 915 Capitol Mall, Room 364 Sacramento, CA 95814 RE: Sacred Sites Inventory Request Project Information: Project Name Southern Heights Bridge Replacement Project Address Southern Heights Boulevard, San Rafael, Marin County, CA. USGS Quadrangle 7.5’ USGS San Rafael quadrangle (1993) Township 1 North Range 6 West Section(s) 4 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. • Ev ANS t'!l DE SHAZO LLC RCHAEOLOGY (9 HISTORIC PRESER\~ATION I l 6876 Sebastopol Avenue Sebastopol, CA 95472 (707) 812-7400 | www.evans-deshazo.com We are contacting you to request a Sacred Sites inventory for the Project Area (APE map attached) and a list of Native Americans to contact for further information.

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.

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, \/ MARK THOMAS Scope of Work - Southern Heights Bridge Replacement City of San Rafael 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 in bidding and construction.
