GENERAL PLAN 2040
Informational Report
CITY COUNCIL
JUNE 3, 2019
OVERVIEW
History of traffic planning and management
Senate Bill 743-CEQA changes + phase out of LOS
Introduction of “vehicle miles traveled” (VMT)
Options to LOS
Next steps
HISTORY
1983 = “level of service” (LOS) introduced to coordinate
traffic with land development (Northgate)
LOS “grades” intersections/arterials from “A” to “F”
LOS = universal approach to assessing vehicle movement
impacts for CEQA review
1988 General Plan 2000 and 2004 General Plan 2020 +
EIRs= LOS memorialized with long-range planning
GENERAL PLAN 2020 “LOS” POLICIES
LOS “D” standard citywide for intersections/arterials
LOS “E” standard for Downtown and selected areas
LOS standard maintained through implementing
planned transportation improvements (Exhibit 21)
Traffic mitigation fee charged to new development
($4,246/AM + PM peak hour trip)
SB 743 –Signed by Governor 2013
Focuses on reducing GHG emissions
Major changes to CEQA Guidelines + two partsoPhase-out of LOS for analyzing traffic/circulation impacts; replace with VMT or similar method
o Transit-oriented development in “transit-priority area” (“TPA”) and covered by a Specific Plan = exempt from CEQA
VMT model (+ EIR) must be adopted and in operation by mid-2020
WHAT IS “VMT?”
Measures the amount and distance of vehicle travel (origin and destination) attributed to a project or use. . .
the longer the distance; the greater the impact
Assesses the effects of a project on regional traffic and use of transit and non-motorized vehicles
Favors projects close to transit (bridging housing + employment)
Established based on the region’s existing travel patterns with unique thresholds (white paper in process)
SB 743 DOES NOT. . .
Assess vehicle trip impacts on the road network
Effect existing traffic fee programs adopted by local jurisdictions
Prevent local jurisdictions from considering capacity and congestion issues in TPAs
Prevent local jurisdictions from accessing growth
Prevent local jurisdictions from continuing to use LOS as a management tool
UNDERTANDING “LOS?”
Well understood metric
Currently set as the performance measure for the roadway
network & establishes the significance criteria
Presents a big unknown for development and adds idle time
We must stop using it as a performance measure (SB 743)
We are not prohibited from using it as a tool
SAN RAFAEL OPPORTUNITIES
Establish a management and monitoring system of local
traffic
INITIAL GOALS:
Easy to predict and implement by development community
Easy to understand by City decision makers and all
stakeholders
Logical, equitable and nexus driven
Based on a multi-modal and well-funded improvement
program
SAN RAFAEL OPTIONS -Concepts
Arterial Delay Index
Trip Monitoring –Within Established Zones
Status Quo, Maintaining Level of Service
No Local Monitoring –Use VMT as the only metric
Arterial Delay Index
Develop a simple ratio between congested and uncongested
travel time
Basically a simplified version of arterial level of service
Include major arterials for each area of the City i.e for the
Downtown area (Ex. Second and Third Streets)
A project will be cleared locally if the expected travel times
after the project is maintained.
Trip Monitoring
Quantify 2040 GP Growth in terms of
AM and PM Peak hour trips for each
Traffic Attraction Zone in the City’s
Planning Model
Growth will be allowed with minimal
traffic review until a percentage point of
the growth is reached (% TBD)
Once the growth hits the target, require
limited traffic analysis
Status Quo, Maintain LOS
Continue to use LOS in our current
General Plan
Costly and repetitive process
VMT Only. No Local Monitoring
Develop a VMT threshold
No other analysis would be used to monitor local growth
SAN RAFAEL OPTIONS
Arterial Delay Index
Trip Monitoring –Within Established Zones
Status Quo, Maintaining Level of Service
No Local Monitoring –Use VMT as the only metric
INFORMATIONAL REPORT –
Accept report –no other action
Comment on LOS methodology options
Next Steps. . .
o “White Paper” to be completed in one month
o Return to City Council for more detailed report +
policy direction
