TOPIC: CHANGE IN SPEED LIMIT ON EIGHTEEN SAN RAFAEL ROADWAY SEGMENTS SUBJECT: INTRODUCTION OF AN ORDINANCE REGARDING SPEED LIMIT CHANGES ON 18

SAN RAFAEL ROADWAY SEGMENTS OUTSIDE OF DOWNTOWN PURSUANT TO SECTIONS 22357 AND 22358 OF THE CALIFORNIA VEHICLE CODE; CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) DETERMINATION: EXEMPT PURSUANT TO STATE CEQA GUIDELINE 15061(b)(3)
RECOMMENDATION:

Staff recommends that the City Council introduce the Ordinance, waive further reading, and refer to it by title only.

BACKGROUND:

The purpose of setting speed limits is to promote safety on roadways while ensuring fair enforcement of vehicle speeds under California law. According to the California Vehicle Code (CVC) Section 22350, drivers are required to operate their vehicles at speeds that are “reasonable and prudent,” taking into consideration factors such as weather, visibility, traffic, road conditions, and the safety of others. The 85th percentile speed that is used for determining posted speed limits—defined as the speed at or below which 85% of vehicles travel—is generally used to determine what is “reasonable and prudent.” CVC Section 22352 defines prima facie speed limits, which are presumed speed limits even if not explicitly indicated by a posted sign, for certain roadways. A prima facie speed limit of 25 miles per hour (mph) applies to roadways that meet the CVC definition of business districts, residence districts, school zones, and areas immediately adjacent to senior centers.

For roadways outside these categories, CVC Section 22358 permits local jurisdictions to establish speed limits that are determined to be reasonable and safe based on an engineering and traffic survey (E&TS) conducted in accordance with CVC Section 627. Furthermore, under CVC Section 40802, posted speed limits must be updated every seven (7) years to remain enforceable. The update interval of the E&TS can be extended to 14 years when a registered engineer confirms no significant changes in roadway or traffic conditions. Posted speed limits without a current E&TS are enforceable by the Police Department by pacing, but not by radar.

SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 2
An E&TS consists of engineering measurements of prevailing free-flow speeds on relevant roadway segments, a review of the collision history, and a review of roadside conditions not readily apparent to passing motorists. Speed surveys identify the 85th-percentile speed, which has historically been the primary factor used to establish the speed limit in accordance with the CVC.

California Assembly Bill 43 (AB 43), signed into law in October 2021, requires E&TS reports to consider the presence and safety of vulnerable roadway users, such as bicyclists and pedestrians, when establishing speed limits. Under AB 43, a "safety corridor" is a roadway segment within an overall roadway network where the highest number of serious injury and fatality crashes occurs and that meets certain other requirements (CVC Section 22358.7). Local jurisdictions are permitted to reduce speed limits by an additional 5 mph within safety corridors where the findings of an E&TS justify such reductions.

The City’s E&TS were scheduled to expire in October 2025; therefore, the City entered into an agreement with traffic engineering consultant W-Trans to conduct a citywide E&TS update, shown in Attachment 1.

The updated E&TS complies with CVC regulations and guidelines established by the California Department of Transportation (Caltrans) in the California Manual on Uniform Traffic Control Devices (CA_MUTCD) for Setting Speed Limits (2026). Additionally, City staff entered into an agreement with Parametrix to conduct a supplemental study to evaluate the possibility of reducing downtown speed limits through the application of AB 43 under CVC Section 22358.7, whose provisions became effective on July 1, 2024. The downtown area was prioritized for the first phase (Phase 1) of AB 43 implementation because it serves as both a key business district and as a hub for pedestrian and bicycle activity in the city. Importantly, the 2024 Marin County Local Road Safety Plan (LRSP) indicates that many streets in downtown San Rafael experience elevated collision rates.

The LRSP also identifies that unsafe vehicle speed is the most common primary collision factor leading to injuries in San Rafael. The report indicates that reducing speed limits along high collision network segments would not only improve safety outcomes for vulnerable roadway users but also enhance the overall pedestrian experience and support economic vitality. The high concentration of pedestrian and bicycle-generating land uses underscores the importance of ensuring safety in an environment that supports vibrant commercial uses and significant foot traffic.

During the February 18, 2025 City Council meeting, the updated E&TS speed surveys were approved.

The surveys are summarized in Attachment 2. The ordinance to reduce speed limits on 24 roadways in downtown San Rafael was introduced and was adopted at the March 3, 2025 City Council meeting. The speed limit changes that went into place as a part of Phase 1 of AB 43 implementation resulted in a generally contiguous 20 mph ‘zone’ in downtown, including the east-west corridors of Mission Avenue, Fifth Avenue, and Fourth Street, as well as north-south streets west of US Highway 101 between Mission Avenue and Second Street. Each recommended speed limit constituted a five-mph reduction compared to the existing conditions in downtown west of US Highway 101, except for Second and Third Streets between Hayes Street and Heatherton Street, which retain a 25-mph speed limit.

ANALYSIS:

While working to complete Phase 1 of AB 43 implementation by installing new speed limit signs on downtown streets, the City began evaluating possible speed limit reductions in additional areas of the City as part of Phase 2 of AB 43 implementation. The strategy and speed surveys are summarized in Attachment 3. The proposed roadways are outside downtown and located near land uses that generate high volumes of vulnerable roadway users, such as parks, community centers, schools, senior housing, and designated bicycle facilities. When determining the proposed locations for Phase 2 speed limit reductions, community input from the City’s issue reporting platform, SeeClickFix, was considered, along with the online survey posted on the City’s project website during Phase 1 and ongoing conversations with the San Rafael Police Department.

SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 3
Based on the E&TS results and additional inputs as stated, speed limits are recommended for a five-mph reduction on the following 18 roadway segments outside of the downtown area listed in Table 1.

18 Woodland Avenue (Du Bois Street to Auburn Street) 30 25 In each case of recommended reduced speed limits, it was determined that the resulting speed limit facilitates the orderly movement of traffic and is reasonable and safe, under CVC Section 22358. The recommended speed limit reduction on Point San Pedro is being coordinated with the County of Marin to promote continuous speed limits through the corridor of road.

The implementation of AB 43 Phase 1 and 2 speed limit reductions, in conjunction with other recent and planned infrastructure improvements in downtown San Rafael, are anticipated to create a safer and more inviting environment for pedestrians, cyclists, and motorists alike. The recommended speed limits are part of a comprehensive approach to improve traffic safety and slow vehicle speeds, helping to foster a more livable and accessible community.

ENVIRONMENTAL REVIEW:

The proposed speed limit modifications are exempt from the California Environmental Quality Act (CEQA). The adoption of the proposed ordinance is not a “Project” under CEQA Guidelines Section 15378(a), in that the action does not have a potential for a direct physical change or reasonably indirect physical change in the environment. In the event that the action is considered a “Project” under CEQA, the action is exempt from CEQA under section 15061(b)(3) of the CEQA Guidelines because it can be SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 4
seen with certainty that there is no possibility that the adoption of this Ordinance or its implementation would have a significant effect on the environment (14 Cal. Code Regs. Section 15061(b)(3)).

COMMUNITY OUTREACH:

AB 43 Phase 1 preliminary results and locations of speed limit reductions in the downtown area were shared on the project website and presented to the San Rafael Bicycle and Pedestrian Advisory Committee (BPAC) on October 2, 2024. The community and committee members were supportive of the speed limit reduction efforts and expressed interest in expanding the areas to which AB 43 would apply.

As such, City staff worked with Parametrix to conduct supplemental E&TS and to incorporate additional downtown streets into the speed limit reduction recommendations. The updated speed limit reduction results were presented to the Police Advisory and Accountability Committee (PAAC) on January 15, 2025, and to City Council on February 18, 2025. The final speed limit ordinance was adopted at the City Council meeting on March 3, 2025.

The community and committees again expressed support for the speed limit reduction efforts and interest in evaluating speed limit reduction in other areas of the City. As a result, AB 43 Phase 2 proposed locations for speed limit reductions on San Rafael roadways outside of downtown were presented at the BPAC meeting on December 3, 2025, and at the PAAC meeting on April 15, 2026.

The City has hosted an Assembly Bill 43 (AB 43) Strategy website since October 2024 that includes information on AB 43 and frequently asked questions. An online form remains open for residents to provide their input on Phases 1 and 2 of AB 43 implementation.

FISCAL IMPACT:

The cost to install new speed limit signs and pavement marking changes to be performed by the Streets Maintenance Division staff will be absorbed by the department’s fiscal year 2026-27 budget.

OPTIONS:

The City Council has the following options to consider relating to this matter:

1. Introduce the Ordinance, waive further reading of the Ordinance, and refer to it by title only, as presented.

2. Do not introduce the Ordinance and provide alternative direction to staff.

RECOMMENDED ACTION:

Staff recommends that the City Council introduce the Ordinance, waive further reading, and refer to it by title only.

Appendix: Engineering and Traffic Survey Forms
1 Overview
This report presents the results of an evaluation of speed limits in downtown San Rafael reflecting California Assembly Bill No. 43 (AB 43) and results of Engineering and Traffic Surveys (E&TS). AB 43 provides jurisdictions with more flexibility when establishing speed limits in order to account for the presence of vulnerable roadway users and for the purpose of improving roadway safety outcomes.

AB 43, effective in 2022, amends the California Vehicle Code (CVC) and revises the process by which an E&TS is prepared. An E&TS is an engineering study used for setting roadway speed limits based on prevailing speeds (or 85th percentile speed) and a review of roadway traffic conditions and history.

AB 43 allows for reduction of speed limits after considering safety, land uses, and concentration levels of people walking and riding bicycles, especially from vulnerable groups such as children, seniors, persons with disabilities, and individuals experiencing homelessness. AB 43 also allows lowered speed limits on sections of roadways in a “business activity district,” such as neighborhood downtowns.

The 2024 Marin County Local Road Safety Plan indicates that many streets in downtown San Rafael experience elevated collision rates, and that reducing vehicle speeds could improve safety outcomes of vulnerable road user groups. Slower vehicle speeds offer drivers more reaction time and reduce the required distance to stop a traveling vehicle and can not only make the street safer for people inside and outside a vehicle, but they also facilitate a calmer and more enjoyable street environment overall. As such, the City of San Rafael has undertaken work to evaluate speed limits in the downtown area, where most of the city’s vehicle collisions resulting in injury or fatality occur, and where the most roadways that meet the CVC definition of “business activity district” are located.

This report evaluates speed limits in downtown San Rafael in the context of AB 43. In doing so, roadways that meet the definition of “business activity district” were identified, and recent E&TS results were analyzed for appropriate speed limit reductions. The resulting speed limit recommendations are shown below in Table 1.

3 Statutory Speed Limits
There are three primary classifications of statutory speed limits in California, including absolute speed limits, prima facie speed limits, and intermediate speed limits. An absolute speed limit indicates the speed above which it is unlawful to drive regardless of roadway conditions or other factors. All California roadways are subject to an absolute speed limit of 55 miles per hour (mph) on two-lane undivided roadways and 65 mph on all other roadways, as outlined in the CVC §22349. A prima facie speed limit is a presumed speed limit appropriate for certain roadway contexts.

Residential and business districts have a prima facie speed limit of 25 mph. Intermediate speed limits between absolute and prima facie speed limits can be established on the basis of an E&TS in accordance with the CVC §22357 and §22358.

Along roadways that lack a posted speed limit, the roadway is subject to a statutory “prima facie” speed limit as established in the CVC §22352. The prima facie speed limit sets one of two speed limits covering six classes of location:

1. 15 mph – uncontrolled railway crossings; blind, uncontrolled intersections; and alleyways.

2. 25 mph – business district or residence district without other posted speed limits; school zones; and areas immediately around senior centers.

The following conditions outlined in the CVC §235 define a business district as the portion of a roadway:
• Upon one side of which, for a distance of 600 feet, 50 percent or more of the contiguous property fronting thereon is occupied by buildings in use for business, or • Upon both sides of which, collectively, for a distance of 300 feet, 50 percent or more of the contiguous property fronting thereon is so occupied.

The following conditions listed in the CVC §515 define a residence district as the portion of a roadway:
• Upon one side of which, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures, or
• Upon both sides of which, collectively, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures.

Business and residence districts may be longer than the distances specified in the above definitions if the ratio of businesses or residential dwellings to the length of the roadway exists. CVC §240 includes additional requirements to be applied in determining whether a roadway is within a business or residence district.

Additionally, the CVC §22358.4(b) includes provision for a local authority to declare a prima facie speed limit of 20 or 15 mph in school zones under certain circumstances. The CVC §22358.9 allows 4 January 2025 │
for establishment of a prima facie speed limit of 25 or 20 mph in a “business activity district” that meets at least three of the four following requirements:

1. No less than 50 percent of the contiguous property fronting the highway consists of retail or dining commercial uses, including outdoor dining, that open directly onto sidewalks adjacent to the highway.

2. Parking, including parallel, diagonal, or perpendicular spaces located alongside the highway.

3. Traffic control signals or stop signs regulating traffic flow on the highway, located at intervals of no more than 600 feet.

4. Marked crosswalks not controlled by a traffic control device.

Speed Limits Established by E&TS
As outlined in the CVC §22357 and §22358, where statutory speed limits are not appropriate for roadway, traffic, or land use conditions, road authorities have the power to establish speed limits different from the statutory absolute or prima facie speed limit. Speed limits of 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 mph must be established by an E&TS and be approved by a registered Civil or Traffic Engineer. The E&TS determines the recommended speed limits along each surveyed roadway segment.

In accordance with the CVC §627, the E&TS consists of engineering measurements of the prevailing free-flow speeds along survey segments, a review of the collision history reports, and a review of existing roadside conditions including the identification of any conditions not readily apparent to the motorist. An E&TS may also consider additional factors such as residential density and safety of bicyclists and pedestrians, with increased consideration for vulnerable pedestrian groups including children, seniors, persons with disabilities, users of personal assistive mobility devices, and the unhoused.

Speed limits are established at or near the 85th percentile speed (also known as the critical speed), which is defined as the speed at or below which 85 percent of the traffic is moving. Statistically the 85th percentile represents one standard deviation above the average speed and establishes the upper limit of what is considered reasonable and prudent (CAMUTCD Section 2B.13).

According to the CVC §22358.6(a), an E&TS shall establish posted speed limits at the nearest 5 mph increment of the 85th percentile speed of free-flowing traffic.

As per the CVC, exceptions to the establishment of speed limits at the nearest 5 mph increment of the 85th percentile are permissible only in the following cases as described in items 1 – 4 below.

Determination must be made based on results of an E&TS and determination of reasonable or safe speed limits. Chapter 2 (“Signs”) of the CA MUTCD further establishes guidelines for setting a speed limit that provides a rational and defensible speed limit determination with the use of an E&TS. 5 1. Speed limit reduction from 85th percentile by increments of 5 mph • If the 85th percentile speed is rounded up, then it can be rounded down by 5 mph: For cases in which the nearest 5 mph increment of the 85th percentile speed would require rounding up, a local authority may decide to instead round down the speed limit to the nearest 5 mph increment below the 85th percentile speed. (CVC §22358.6(c)) • If the 85th percentile speed is rounded down, an additional 5 mph reduction can be applied for conditions not readily apparent to driver: For cases in which the nearest 5 mph increment of the 85th percentile speed would require a rounding down, a local authority may lower the speed limit by 5 mph from the nearest 5 mph increment of the 85th percentile speed in compliance with CVC §627, §22358.5 and the CA MUTCD and if the reasons for the lower speed limit are documented. (CVC §22358.6(b))
• An additional 5 mph reduction can be applied if street is a “Safety Corridor” or adjacent to a “high bicycle / pedestrian generator”:
1 If a local authority, after completing an engineering and traffic survey, finds that the speed limit is still more than is reasonable or safe, the local authority may, by ordinance, determine and declare a prima facie speed limit that has been reduced an additional five miles per hour for either of the following reasons below (CVC §22358.7):
o The portion of highway has been designated as a safety corridor. A local authority shall not deem more than one-fifth of their streets as safety corridors. (CVC §22358.7(a)(1))
▪ The CA MUTCD, Table 2B-105(CA) lists factors for consideration when identifying safety corridor roadways, including crash severity, mode, disadvantaged community status, vulnerable populations, school proximity, and crash density.
o The portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and the unhoused. (CVC §22358.7(a)(2))
▪ The CA MUTCD, Table 2B-106(CA) lists requirements to determine if a facility generates high concentrations of bicyclists or pedestrians. Examples include certain land uses, transit factors, presence of pedestrian / bicyclist infrastructure, and demographic factors.

As per the CVC §22358.6(e), the total reduction in the speed limit pursuant to the three items listed above shall not exceed 12.4 miles per hour from the 85th percentile speed. The CA MUTCD further clarifies the options to apply speed limit reduction from the 85th percentile speed with several examples, which are replicated in Table 2:
1 As per the CVC §22358.7, a local authority may not lower a speed limit as authorized by this section until June 30, 2024

2. Retain existing or restore immediately prior adopted speed limit A local authority may, by ordinance, retain the currently adopted speed limit or restore the immediately prior adopted speed limit if that speed limit was established with an engineering and traffic survey and if a registered engineer has evaluated the section of roadway and determined that no additional general purpose lanes have been added to the roadway since completion of the traffic survey that established that speed limit. (CVC §22358.8) 7 Speed Survey Operational Procedures
Speed surveys were conducted on certain roadway segments that were not included in the 2024 report Engineering and Traffic Surveys for the City of San Rafael. These roadway segments include:
• Fifth Avenue between H Street and Hetherton Street
• H Street between Mission Avenue and Fourth Street
• G Street between Mission Avenue and Second Street
• F Street between Fifth Avenue and Latham Street
• E Street between Mission Avenue and Second Street
• D Street between Fifth Avenue and First Street
• C Street between Mission Avenue and Second Street
• Tamalpais Avenue between Mission Avenue and Second Street Speed surveys were conducted in compliance with regulations set forth in the California Vehicle Code (CVC) and were based on the guidelines for setting proper speed limits established by the California Department of Transportation (Caltrans) as documented in the California Manual for Setting Speed Limits (2020). The E&TS consists of engineering measurements of the prevailing freeflow speeds along survey segments, a review of the collision history reports, and of existing roadside conditions, including the identification and description of any conditions not readily apparent to the motorist.

Technical experts conducted field surveys of existing vehicle speeds along the E&TS roadway segments. The data was collected in September, October, and November 2024 on clear weather weekdays with dry pavement conditions. The surveys were done during off-peak hours to capture traffic speeds under free-flow conditions. Vehicle speeds along the E&TS segments were collected using a portable calibrated radar gun. The surveyor was strategically located to remain inconspicuous to avoid influencing driver speeds. Surveyor locations were selected so that prevailing speeds could be considered representative of the speed zone section. For each segment, the surveyor distanced themselves from nearby traffic signals and stop signs to minimize their effects on vehicular travel speeds.

The surveyor read speeds directly from the radar gun and recorded the free-flow speeds of a minimum of 100 vehicles along each roadway segment, except those segments which had exceptionally low traffic volume (such as Tamalpais Ave). The surveys captured both directions of travel along each study segment. Each direction consisted of no less than 50 vehicles. 8 January 2025 │
Roadway Characteristics
As part of the speed survey assessment, the existing conditions along the E&TS roadway segments were determined. The roadway segment lengths were measured, and observations were made on the presence of on-street parking, sidewalks, and bicycle facilities. These roadway conditions were considered during speed limit evaluations and were used to determine appropriate speed limits that would promote all roadway user safety.

Data Analysis
The sample vehicle speeds collected during the field surveys were assessed for the following statistical factors:
• Average speed – the summation of measured speeds divided by the number of observed vehicles.
• Median speed (i.e., the 50th percentile speed) – the speed above and below which 50 percent of the sample speeds lie.
• 85th percentile speed – the speed at or below which 85 percent of free-flow vehicles travel.

Also referred to as the critical speed, the 85th percentile speed is the primary factor used to determine the speed limit and may be subject to secondary factors of collision history and other conditions not apparent to drivers.
• 10 mph pace speed – the 10 mph increment of speed containing the greatest number of vehicles. The number of vehicles in the pace speed is reported as a percentage of vehicles surveyed. The pace speed aids in determining the proper speed limits. Generally, the critical speed lies within the pace speed.

Collision Review
The E&TS Survey analysis also reviewed the collision history of the roadway segments, obtained from the Statewide Integrated Traffic Records System (SWITRS). The data consisted of the most recently available five-year period of reported collision histories (January 1, 2018, to December 31, 2022). At the time of the study, 2023 data had not yet been certified in the record system.

The number of reported collisions along each roadway segment during the five-year period as well as the average daily traffic (ADT) volumes were used to calculate the rate for each roadway segment.

These calculated rates were compared to the statewide average collision rates for the same type of roadway and configuration. The purpose of the comparison was to determine if the collision history along the roadway segment deviated from the statewide average and potentially represented an unusually high collision rate. The statewide average collision rates were based on the width, configuration, and terrain of each roadway segment.
9 Downtown San Rafael AB 43 Results
Speed limits are recommended for each of the roadway segments studied based on the approach adopted with AB 43 and on policies described in the CVC and CA MUTCD. The roadway segments that were determined to meet the definition of a “business activity district” as per CVC §22358.9 and are eligible for establishment of a 20-mph prima facie speed limit without requiring an engineering and traffic survey include the following:
• Fourth Street between Marquard Avenue and Hetherton Street • Shaver Street between Fourth Street and Second Street • B Street between Mission Avenue and Second Street
• A Street between Fifth Avenue and Second Street
• Lootens Place between Fifth Avenue and Third Street
• Cijos Street between Fourth Street and Third Street
• Lincoln Avenue between Mission Avenue and Second Street E&TS results and recommended speed limits for Mission Avenue and Second Street were identified from Engineering and Traffic Surveys for the City of San Rafael. Appendix A contains E&TS results for additional roadway segments evaluated in Fall 2024 as part of this study.

Table 3 summarizes recommended downtown San Rafael speed limits resulting from this study.

Each of these recommended speed limits constitutes a five-mph reduction in speed limit compared to existing conditions, with the exception of Second and Third Streets between Hayes Street and Hetherton Street, which would retain a 25-mph speed limit. These speed limits would also result in a generally contiguous 20 mph ‘zone’ in downtown that includes the east-west corridors of Mission Avenue, Fifth Avenue, and Fourth Street, as well as north-south streets west of US Highway 101 between Mission Avenue and Second Street.

These speed limit reductions, when considered in conjunction with other recent and planned infrastructure improvements in downtown San Rafael, are anticipated to create a safer and more inviting environment for all roadway users, including people walking, biking, and driving. The recommended speed limits are part of a comprehensive approach intended to improve traffic safety and slow vehicle speeds, helping to foster a more livable and accessible community.

A Engineering and Traffic Survey Forms
B Prior Engineering and Traffic Surveys Updated Pursuant to AB 43 1 Overview
The report City of San Rafael AB 43 Strategy and Downtown Speed Limits (January 2025) presented results of an evaluation of speed limits on roadways in downtown San Rafael reflecting California Assembly Bill No. 43 (AB 43) and results of Engineering and Traffic Surveys (E&TS). This report presents the results of a similar speed limit evaluation of citywide roadways outside of downtown San Rafael.

AB 43 provides jurisdictions with more flexibility when establishing speed limits in order to account for the presence of vulnerable roadway users and for the purpose of improving roadway safety outcomes. AB 43, fully effective in 2024, amends the California Vehicle Code (CVC) and revises the process by which an E&TS is prepared. An E&TS is an engineering study used for setting roadway speed limits based on prevailing speeds (or 85th percentile speed) and a review of roadway traffic conditions and history. AB 43 allows for reduction of speed limits after considering safety, land uses, and concentration levels of people walking and riding bicycles, especially from vulnerable groups such as children, seniors, persons with disabilities, and individuals experiencing homelessness.

The 2024 Marin County Local Road Safety Plan indicates that many streets in San Rafael experience elevated collision rates, and that reducing vehicle speeds could improve safety outcomes of vulnerable road user groups. Slower vehicle speeds offer drivers more reaction time and reduce the required distance to stop a traveling vehicle and can not only make the street safer for people inside and outside a vehicle, but they also facilitate a calmer and more enjoyable street environment overall.

The City of San Rafael has previously undertaken work to evaluate speed limits in the downtown area, and this report evaluates speed limits on roadways outside of downtown San Rafael in the context of AB 43. In doing so, roadways with elevated crash rates and that are adjacent to land uses that generate high volumes of pedestrians and bicyclists were identified, and recent E&TS results were analyzed for appropriate speed limit reductions. The resulting speed limit recommendations are shown below in Table 1 and displayed on a map in Figure 1. 2 June 2026 │

Statutory Speed Limits
There are three primary classifications of statutory speed limits in California, including absolute speed limits, prima facie speed limits, and intermediate speed limits. An absolute speed limit indicates the speed above which it is unlawful to drive regardless of roadway conditions or other factors. All California roadways are subject to an absolute speed limit of 55 miles per hour (mph) on two-lane undivided roadways and 65 mph on all other roadways, as outlined in the CVC §22349. A prima facie speed limit is a presumed speed limit appropriate for certain roadway contexts.

1. 15 mph – uncontrolled railway crossings; blind, uncontrolled intersections; and alleyways.

2. 25 mph – business district or residence district without other posted speed limits; school zones; and areas immediately around senior centers.

Additionally, the CVC §22358.4(b) includes provision for a local authority to declare a prima facie speed limit of 20 or 15 mph in school zones under certain circumstances. The CVC §22358.9 allows 5 for establishment of a prima facie speed limit of 25 or 20 mph in a “business activity district” that meets at least three of the four following requirements:

2. Parking, including parallel, diagonal, or perpendicular spaces located alongside the highway.

3. Traffic control signals or stop signs regulating traffic flow on the highway, located at intervals of no more than 600 feet.

4. Marked crosswalks not controlled by a traffic control device.

According to the CVC §22358.6(a), an E&TS shall establish posted speed limits at the nearest 5 mph increment of the 85th percentile speed of free-flowing traffic.

As per the CVC, exceptions to the establishment of speed limits at the nearest 5 mph increment of the 85th percentile are permissible only in the following cases as described in items 1 – 4 below.

1. Speed limit reduction from 85th percentile by increments of 5 mph • If the 85th percentile speed is rounded up, then it can be rounded down by 5 mph: For cases in which the nearest 5 mph increment of the 85th percentile speed would require rounding up, a local authority may decide to instead round down the speed limit to the nearest 5 mph increment below the 85th percentile speed. (CVC §22358.6(c)) • If the 85th percentile speed is rounded down, an additional 5 mph reduction can be applied for conditions not readily apparent to driver: For cases in which the nearest 5 mph increment of the 85th percentile speed would require a rounding down, a local authority may lower the speed limit by 5 mph from the nearest 5 mph increment of the 85th percentile speed in compliance with CVC §627, §22358.5 and the CA MUTCD and if the reasons for the lower speed limit are documented. (CVC §22358.6(b))
• An additional 5 mph reduction can be applied if street is a “Safety Corridor” or adjacent to a “high bicycle / pedestrian generator”: If a local authority, after completing an engineering and traffic survey, finds that the speed limit is still more than is reasonable or safe, the local authority may, by ordinance, determine and declare a prima facie speed limit that has been reduced an additional five miles per hour for either of the following reasons below (CVC §22358.7):
o The portion of highway has been designated as a safety corridor. A local authority shall not deem more than one-fifth of their streets as safety corridors. (CVC §22358.7(a)(1))
▪ The CA MUTCD, Section 2B.21, paragraphs 12ai to 12as provide further definition for jurisdictions to apply when identifying roadways as a “Safety Corridor.” CA MUTCD Table 2B-105(CA) lists factors for consideration when identifying safety corridor roadways, including crash severity, mode, disadvantaged community status, vulnerable populations, school proximity, and crash density.
o The portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and the unhoused. (CVC §22358.7(a)(2))
▪ The CA MUTCD, Section 2B.21, paragraphs 12at to 12az provide further definition for jurisdictions to determine if a facility generates high concentrations of bicyclists or pedestrians. CA MUTCD Table 2B-106(CA) lists generators of high concentrations of bicycles or pedestrians. Examples include certain land uses, transit factors, presence of pedestrian / bicyclist infrastructure, and demographic factors.

Speed surveys were conducted in compliance with regulations set forth in the California Vehicle Code (CVC) and were based on the guidelines for setting proper speed limits established by the California Department of Transportation (Caltrans) as documented in the California Manual for Setting Speed Limits (2020). The E&TS consists of engineering measurements of the prevailing freeflow speeds along survey segments, a review of the collision history reports, and of existing roadside conditions, including the identification and description of any conditions not readily apparent to the motorist.

Technical experts conducted field surveys of existing vehicle speeds along the E&TS roadway segments. The data was collected on clear weather weekdays with dry pavement conditions. The surveys were conducted during off-peak hours to capture traffic speeds under free-flow conditions.

Vehicle speeds along the E&TS segments were collected using a portable calibrated radar gun. The surveyor was located to remain inconspicuous to avoid influencing driver speeds. Surveyor locations were selected so that prevailing speeds could be considered representative of the speed zone section. For each segment, the surveyor distanced themselves from nearby traffic signals and stop signs to minimize their effects on vehicular travel speeds.

Roadway Characteristics
As part of the speed survey assessment, the existing conditions along the E&TS roadway segments were determined. The roadway segment lengths were measured, and observations were made on the presence of on-street parking, sidewalks, and bicycle facilities. These roadway conditions were considered during speed limit evaluations and were used to determine appropriate speed limits that would promote all roadway user safety.

Data Analysis
The sample vehicle speeds collected during the field surveys were assessed for the following statistical factors:
• Average speed – the summation of measured speeds divided by the number of observed vehicles.
• Median speed (i.e., the 50th percentile speed) – the speed above and below which 50 percent of the sample speeds lie.
9 • 85th percentile speed – the speed at or below which 85 percent of free-flow vehicles travel.

The number of reported collisions along each roadway segment during the five-year period as well as the average daily traffic (ADT) volumes were used to calculate the rate for each roadway segment.

Table 3 summarizes recommended San Rafael speed limits resulting from this study. Each of these 18 recommended speed limits constitutes a five-mph reduction in speed limit compared to existing conditions.

Appendix A contains E&TS results for speed surveys that were conducted in 2025, and Appendix B contains E&TS results for which speed surveys were conducted as part of Engineering and Traffic Surveys for the City of San Rafael (2024).

These speed limit reductions, when considered in conjunction with other recent and planned infrastructure improvements in San Rafael, are anticipated to create a safer and more inviting environment for all roadway users, including people walking, biking, and driving. The recommended speed limits are part of a comprehensive approach intended to improve traffic safety and slow vehicle speeds, helping to foster a more livable and accessible community. 11 Table 3 Summary Table of Speed Limit Recommendations Roadway Between
