2 Executive Summary
Guided by the Safe System Approach, the City of Santa Monica (City) initiated this study evaluating roadway speeds and speed limits to improve the safety of its roadway system. As part of this effort, Fehr & Peers was contracted to prepare an Engineering and Traffic Survey (E&TS) for 141 roadway segments composed of 215 data collection locations, and to complete an analysis that resulted in recommended speed limit updates as defined by California Vehicle Code (CVC) Section 627 and the 2014 California Manual on Uniform Traffic Control Devices (CA MUTCD), Revision 8.
To update speed limits, the speed data were analyzed to set reasonable and appropriate speed limits in consideration of the following Assembly Bill 43 mechanisms: namely, Safety Corridors, Bicyclist and Pedestrian Activity Generators, Business Activity Districts, and historic speed limit retention. Additionally, speed limit continuity and existing infrastructure were taken into account, including the City’s Priority Network, principal arterial designation, bikes lanes, neighborhood greenways, K-12 facilities, and public parks.
This effort resulted in identifying 62 roadways segments, which account for 32 roadway miles, where speed limit reductions would be appropriate. The average speed limit reduction for all roadway segments where speed limit reductions were applied was 5 mph.

3 Overview
Guided by the Safe System Approach, the City initiated this project to update speed limits pursuant to Section 22358 of the CVC. The Safe System Approach is a United States Department of Transportation (U.S. DOT) adopted
paradigm that addresses roadway safety. The approach is depicted on the wheel in Figure 1, which promotes five
design elements on the inner ring, and six safe roadway principles on the outer ring. Embedded in this approach is anticipating human mistakes by designing and managing
road infrastructure to keep the risk of mistakes low; and, when a mistake leads to a crash, that the result is not a fatality or serious injury.
To assist the City with this objective, Fehr & Peers prepared an E&TS for 141 roadway segments, and an ensuing
analysis evaluated the potential speed limit reductions on each segment. Two surveys were required for 75 roadway segments (150 total roadway surveys for roadways with raised medians) and one survey was required for 65 roadway segments, yielding a total of 215 roadway locations surveyed. Figure 2 shows a map of existing speed limits, and Figure 3 shows a map of the 85th percentile speed recorded by the surveys.
To update speed limits, the speed data were analyzed for potential speed limit reductions in accordance with Assembly Bill 43 mechanisms: namely, Safety Corridors, Bicyclist and Pedestrian Activity Generators, Business Activity Districts, and historic speed limit retention. More information on the specifications of each of these mechanisms is provided in the next section of this report, Analysis Methodology.
Additionally, speed limit continuity and existing infrastructure were taken into account, including the City’s Priority Network, principal arterial designation, bikes lanes, neighborhood greenways, K-12 facilities, and public parks.
Fehr & Peers produced a list of updated speed limits for all 141 roadway segments in accordance with the CVC. Overall speeds were reduced on 62 roadways, which account for 32 miles of roadway. More details on the results of the analysis are found in the Results section of this report.

6 Analysis Methodology
The goal of this study is to establish enforceable speed limits throughout the City pursuant to Section 22358 of the CVC. To accomplish this, Fehr & Peers developed a methodology that consisted of two main components: data collection and policy review, and data analysis. The result of this effort is an E&TS for the Mobility Division to allow the City to enforce reasonable speed limits on the City’s roadways. The sections below describe how the analysis was conducted.
Data Collection & Policy Review
Fehr & Peers partnered with National Data & Surveying Services (NDS) to collect the required speed and daily travel volume data at 215 roadway locations in the City in accordance with CVC Section 627 and the 2014 CA MUTCD, Revision 8.
While the data was being collected, the following City plans and state legislation were reviewed:
• City of Santa Monica Bicycle Action Plan & Amendment
• Land Use and Circulation Element (LUCE)
• MANGo Concept Plan
• Pedestrian Action Plan
• Local Roadway Safety Plan (LRSP)
• CVC as amended by AB 43: Consideration of factors such as the presence of bicyclists and pedestrians and/or safety corridors in determining speed limits • AB 321: Establishment of prima facie speed limits in school zones and surrounding school grounds Data Analysis
Assembly Bill 43, approved by Governor Gavin Newsom in October 2021, established new practices for how cities can set and enforce speed limits. Before AB 43, local authorities had to round speed limits up or down to the nearest 5 mph speed increment relative to the 85th percentile driving speed observed by traffic and engineering surveys. The 85th percentile speed is the speed at or below which 85 percent of vehicles travel on a roadway. AB 43 changed the way speed limits are set by establishing new rounding practices, and by accounting for more roadway and land use contextual factors. This analysis is consistent with the AB 43 legislation and the 2014 CA MUTCD, Revision 8. It should also be noted that AB 43 extended the period a speed limit justified by a traffic and engineering survey conducted more than seven years ago remains valid, for purposes of speed enforcement, if evaluated by a registered engineer, as Engineering and Traffic Survey

7 specified, to 14 years.1 To determine which corridors could be prioritized for speed limit reductions, the following mechanisms and contextual factors were considered:
• Nearest 5 mph increment to 85th percentile speed allows for rounding down; in addition, all roadways are eligible for additional 5 mph reduction
• Safety Corridor/Priority Network designation (eligible for 5 mph reduction) • Proximity to Bicyclist/Pedestrian Generator (eligible for 5 mph reduction) • Within Business Activity District (eligible for 25 or 20 mph prima facie speed limit) • Retention of historic speed limits
• Proximity to Neighborhood Greenways
• Proximity to K-12 facilities
• Proximity to public parks
The following sections describe how each of these mechanisms were applied to develop updated speed limits.
85th Percentile Speed
Historically, speed limits were set for roadway segments—that did not qualify for prima facie speed limits—by determining the 85th percentile speed through an E&TS, and then rounding to the nearest multiple of five. Prima facie speed limits are speed limits that qualify under criteria outlined in the CVC. In the CVC, qualifying criteria are organized by contextual factors, such as Residence Districts, Business Districts, Business Activity Districts, Senior Zones, and School Buildings and Grounds, among others. If a roadway meets the criteria for any of the prima facie speed limit categories, an E&TS is not needed in order to enforce speed limits. If a roadway does not qualify under a prima facie speed limit category, an E&TS must be conducted to enforce speed limits. Prima facie speed limits are not arbitrary speed limit assignments determined by the preferences of a municipality.
AB 43 changed rounding practices in two ways. First, it allows the observed speed to be rounded down, instead of up, if the speed is in the upper quantile of the nearest multiple of 5; for example, a speed of
47.5 mph could be rounded down to 45 mph, instead of rounded to 50 mph. Second, the speed limit may be reduced by an additional 5 mph if it was previously rounded down by naturally by being in the lower quantile of the nearest multiple of 5; for example, after an observed speed of 42.4 mph is rounded down to 40 mph, it could be further reduced to 35 mph. Examples of 85th percentile speed values and the application of the speed limit criteria described above are shown in Table 1. If a corridor qualifies as a Safety Corridor or a Bicyclist/Pedestrian Generator it is eligible for an additional 5 mph reduction. Taking 1 Speed limits determined via an E&TS are valid for at least 5 years. The validity period can be extended to 7 years if officer training/radar requirements are met, and then further extended to 14 years if a registered engineer has determined that no significant changes to the roadway have occurred (e.g., addition or removal of parking/driveways/travel lanes, changes to traffic control/signal coordination, increase or decrease in ADT, etc.) (CVC 40802).

8 all of these reductions into account, the maximum possible speed limit reduction from the 85th percentile speed is 12.4 mph.

Safety Corridors
According to the CA MUTCD, a Safety Corridor is defined as “a roadway segment within an overall roadway network where the highest number of serious injury and fatality crashes occur.” The Safety Corridor definition requirements from Table 2 identify the characteristics that could be used to categorize Safety Corridors. Additionally, Safety Corridors should not constitute more than 20% of a local jurisdiction’s overall roadway network, and they should account for at least 25% of killed or seriously injured (KSI) collisions.

Injury Safety Corridor
• Crash severity: Fatal Crashes, Serious Injury Crashes • Mode: Pedestrian-bicycle related crashes, vehicle/other • Disadvantaged Community Status: MPO/RTPA or locally defined disadvantaged community status based on most current version of CalEnviroScreen
• Vulnerable Populations: Seniors (age 65 and older) and Youth (under age 15) based on the American Community Survey
• School proximity (within 0.25 miles) based on the California School Campus Database
Crash Density
Each roadway segment block can be converted into ~ 0.25 mile overlapping “corridor” segments to create a consistent unit of measurement and assess the concentration of linear patterns of injuries within a defined distance. The highest scoring (i.e., most fatal and serious injury crashes per mile) “corridor” segments within a street need to be identified and an appropriate threshold set to determine safety corridor eligibility.
Maintenance The jurisdiction can establish a review and re-evaluation frequency for safety corridors. However, such frequency need not exceed seven years.

9 For this analysis, the Safety Corridor network was developed using the Santa Monica Local Roadway Safety Plan (LRSP) Priority Network data, which represents 14 percent of Santa Monica’s centerline miles.
The Priority Network was established in Santa Monica to pinpoint areas where transportation safety measures should be focused. This data includes the identification of street segments that represent the highest concentration of crashes weighted by severity for the most recent four years of collision data (2015-2019) from Transportation Injury Mapping System (TIMS). In addition, the top intersection locations in terms of crash rates were mapped to identify which intersections would benefit from safety enhancements.
Surveyed roadway segments that had at least one-third of their length overlapping with the Priority Network were designated as Safety Corridor qualified. Forty-seven roadway segments of the 141 surveyed qualified under this definition.
Bicyclist or Pedestrian Activity Generators
To qualify as a Bicyclist or Pedestrian Activity Generator, a roadway segment must have one or more generators listed in Table 3 present within a distance of 1,320 feet.2If the roadway segment is longer than 1,320 feet, a minimum of one generator must be present for every 1,320 feet. While most of the study roadway segments have multiple characteristics required to be considered a Bicyclist or Pedestrian Activity Generator, at a minimum all roadways have sidewalks, and as such all study roadways qualify as a Bicyclist or Pedestrian Activity Generator. Given that all study roadways qualified as a Bicyclist or Pedestrian Activity Generator, all roadways which did not meet the Safety Corridor designation, were designated as Bicyclist of Pedestrian Activity Generators. In addition, bicycle infrastructure was taken into account when determining the appropriate speed limit, including bikes lanes and neighborhood greenways.

Business Activity Districts
Assembly Bill 43 also defined the “business activity district” roadway designation. Business Activity Districts are defined as “the portion of a highway and the property contiguous thereto that includes central or neighborhood downtowns, urban villages, or zoning designations that prioritize commercial land uses at the downtown or neighborhood scale.” Per the CA MUTCD, local authorities can declare a 25 or 20 mph prima facie speed limit on a roadway contiguous to a business activity district if the roadway meets all of the following conditions:
1. A maximum of four traffic lanes.
2. A maximum posted 30 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 25 mph speed limit.
3. A maximum posted 25 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 20 mph speed limit.
To qualify as a business activity district, an area must meet at least three of the following four requirements:
1. No less than 50% 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.
There were many roads in Santa Monica that could have been classified as a Business Activity District; however, the 85th percentile reductions are mutually exclusive from the Business Activity District. In other words, local authorities must choose to apply the reductions to the 85th percentile or the Business Activity District. Given these bounds, Fehr & Peers identified two roadway segments that did not meet the Safety Engineering and Traffic Survey
City of Santa Monica
7/29/2024
11 Corridor qualification and were appropriate candidates for the Business Activity District designation: Main Street between Ocean Park Boulevard & southern city limit; and, Montana Avenue between 7th Street & 14th Street. While both of these roadway segments qualified as a Business Activity District, for speed limit continuity purposes and based on the 85th percentile speeds, the existing speed limits were retained.
Speed Limit Retention
CVC section 22358.8 with AB 43 allows local authorities to retain the currently adopted speed limit without further reduction as long as that speed limit was established with an E&TS and if a registered engineer has evaluated the section of roadway and determined that no additional general-purpose lanes have been added since completion of the traffic survey that established the prior speed limit. Olympic Boulevard between I-10 westbound ramp and 11th Street, and 23rd Street between Pico Boulevard and Ocean Park Boulevard were the only two surveyed segments where the updated speed limit was rounded up by more than 2.4 mph to the nearest 5 mph increment relative to the surveyed 85th percentile speed— 32 mph and 21 mph, respectively—in order to restore the immediately prior speed limit of 35 mph.

12 Results
Once all of the mechanisms were applied, the lowest permitted speed limits were identified, and Fehr & Peers collaborated with city staff to determine the appropriate and reasonable speed limit for each study roadway based on contextual factors. As shown in Table 4, this effort resulted in identifying 62 roadways segments, which account for 32 roadway miles, where speed limit reductions would be appropriate. The average speed limit reduction for all roadway segments where speed limit reductions were applied was 2 mph. Figure 4 shows a map of the updated speed limits along all roadway segments surveyed, and Figure 5 shows whether a surveyed roadway segment was identified for a decrease, increase, or no change to existing speed limits. A complete list of the survey results and alternative speed limit updates can be found in Appendix A. Additional reference to school zone considerations is included in Appendix B.
Additionally, as noted in Table 4, the surveys found that the exact 85th percentile speed of vehicles was higher than the posted speed limit at 65 percent of survey locations (e.g., 85th percentile speed of 25.5 > posted speed limit of 25 mph), lower at 29 percent of survey locations, and approximately equivalent at 6 percent of survey locations.

21 Appendix B. School Zones
CVC 22358.4 was also reviewed as a part of this project. CVC 22358.4 allows local authorities to declare a 15 or 20 mph prima facie speed limit within 500 feet of a school building or school grounds and an extended 25 mph prima facie speed limit within 500 to 1,000 feet from a school or school grounds for roadways in residential district that have a maximum posted 30 miles per hour prima facie speed limit immediately prior to and after the school zone, and have a maximum of two traffic lanes. The City Mobility Division provided a list of roadway segments that meet these criteria in school zones where speed limits are 15 mph during specified times on school days. These roadways were reviewed to compare the updated speed limits to the existing school zone speed limit. Table B1 summarizes the street segments that currently have school zone speed limits of 15 mph and the updated speed limits.
