RE: City of San Marcos Engineering and Traffic Surveys – Technical Memorandum

The purpose of this technical memorandum is to document the engineering and traffic survey (E&TS) conducted for the City of San Marcos and provid e recommendations regarding potential speed limit adjustments as appropriate.

Background
The City of San Marcos currently has posted speed limits at 120 roadway segments throughout the City that were previously evalua ted via an Engineer and Traffic Survey (E&TS). The E&TS that was conducted to support these speed limits were conducted over multiple years. Due to changes in traffic conditions that occurred during the COVID-19 pandemic, including driver behavior and traffic volumes, and changes in state law, it was determined that it would be in the interest of the City to conduct a citywide E&TS to determine if adjustments should be made to the existing posted speed limits. Of the 120 roadway segments, 20 were found to meet the characteristics of a residence district or business district per the California Vehicle Code (CVC) and have a prima facie speed limit of 25 MPH per CVC Section 22352; therefore, E&TS were not conducted at these roadway segments. Additionally, two locations, Via Vera Cruz between San Marcos Boulevard and Discovery Street and Bent Avenue between Grand Avenue and Discovery Street, were not evaluated due to ongoing construction. The remaining 98 roadway segments were evaluated as discussed below.

In October 2021, Governor Gavin Newsom signed Assembly Bill (AB) 43 titled “Traffic Safety”. This bill amended the CVC to allow cities to consider the safety of vulnerable road users when setting speed limits on streets with a history of collisions, with special attention to places where people are more likely to walk and bike. The bill also allows the City to maintain and enforce existing speed limits and roll back speed limit increases that were implemented several years ago if the increase was not based on any physical changes to the design of the street. In September 2022, the Governor signed AB 1938, clarifying some provisions in AB 43. The change s affected CVC Sections 22348 through 22431, the most significant changes are in Sections 22358.6 through 22358.8, which are summarized as follows:
 Define Prima Facie speed limit for residential and business district of 25 miles per hour.

Residential streets are defined as streets 40 fe et in width or less, have no more than two lanes, and serve predominantly residential or business uses.  Under existing laws, speed limits must be set no lower than 5 MPH below the nearest 5 MPH increment derived from the 85th percentile speed of a roadway. For instance, if the 85th percentile speed is calculated at 38 MPH, the rounded figure would be 40 MPH, and the lowest permissible posted speed limit following an E&TS would be 35 MPH.  AB1938 amends the California Vehicle Code to permit the California Department of Transportation or local authorities to set the speed limit by rounding down the 85th percentile speed to the nearest 5 miles per hour. For instance, in the scenario described, the local authority could set the speed limit at 35 miles per hour.  AB 43 permits additional reductions of 5 MPH below previously calculated speed zones, especially considering the presence of vulnerable pedestrian groups as a significant factor in

City of San Marcos Engineering and Traffic Surveys 2
setting speed zones. It also mandates a 30-da y warning period before issuing citations for newly lowered speed limits.
 AB 43 addresses the issue of "speed creep," wh ere successive traffic surveys could lead to gradually higher speed limits due to increasing average speeds. For example, if a roadway's posted speed limit was 35 MPH in 2016 and a 2018 survey found the 85th percentile speed had increased to 38 MPH, leading to a reco mmended increase to 40 MPH, subsequent increases could continue. By 2023, this could lead to a recommended speed limit of 45 MPH due to a further increase in the 85th percentile speed to 43 MPH. However, AB43 allows jurisdictions to retain the last recommended speed limit prior to the occurrence of speed creep.

This approach may be used if no additional general-purpose lanes have been added since the existing speed limit was established and it does not authorize a speed limit to be reduced by any more than 5 MPH from the existing speed limit nor below the immediately prior speed limit per CVC 22358.8.

Methodology
Consistent with the requirements set forth by CVC Sections 22348 through 22431, the 2014 California Manual on Uniform Traffic Control Devices (CA-MUTCD, Revision 7 – Effective March 10, 2023), the Caltrans Policy Directive 09-04, and guidance from the Caltrans Manual for Setting Speed Limits (February 2020), an E&TS was carried out across 98 roadway segments in San Marcos.

When determining speed limits, the following characteristics may be considered:

A. Features of the road such as its condition, shoulder width, slope, layout, and visibility range; B. The prevailing (free-flow) speed of the majority of vehicles; C. The type of roadside development and surrounding environment; D. Existing parking practices;
E. Levels of pedestrian and bicycle activity; and
F. Collision rates based on collision history spanning 36 months. Collision rates are typically compared to the most recent available collision rates for typical roadways within Caltrans District 11, as shown in Table 1.

Table 1 – Collision Rates for District 11 Roadways (2019) Lane Type Rates
(Accidents per Million Vehicle Miles)
2 and 3 Lanes 1.33
4+ Undivided 0.84
4+ Divided 0.96
Source: 2019 Crash Data on California State Highways, Caltrans (2019) Note:

Caltrans’ latest collision rate summaries are from 2020 and 2021. However, due to COVID-19 conditions, these years were considered abnormal and 2019 (pre- COVID) was utilized.

E&TS Results
The measurement of free-flow speed was conducted by a qualified technician utilizing a calibrated portable radar. Parameters of the speed measurements include the following:

1. Qualified technician positioned at a distance from the roadway to minimize any potential speed reduction from drivers aware of their presence.

2. The location along roadway segment for measurement was strategically placed at a sufficient distance away from any traffic control devices ensuring the accuracy of free-flow speed data.

City of San Marcos Engineering and Traffic Surveys 3

3. Speed measurements were scheduled during off-peak hours to prevent the free-flow speed from being skewed by traffic congestion.

4. For each directional flow on a given roadway, data from at least 50 vehicles were collected, for a combined total of 100 vehicles minimum for both directions per roadway segment.

5. Additional guidance as outlined in Section 3.2.4 of the Caltrans Manual for Setting Speed Limits was also followed.

Free-flow speed data was collected between Dece mber 2022 and February 2023 by National Data Services (NDS); city staff conducted additional speed data collection between April 2024 and May 2024. Table 2 summarizes the results of this E&TS and categorizes the justification for the recommended posted speed limits. E&TS strip maps are provided in Attachment A.

Overall, the E&TS categorized the speed limit into two categories:

Prima Facie Speed: Streets that qualify as residential or business districts are recommended to have a prima facie speed limit of 25 miles per hour. Roadway segments with this recommendation are listed as “P” in Table 2.

85th Percentile Speed: For streets where the 85th percentile speed is deemed reasonable by rounding or taking an additional five MPH reduction, the speed limit is set based on an Engineering and Traffic Survey (E&TS). Recommendations may involve either maintaining the existing speed limit or adjusting it, taking in to account factors like the roadway segment, accident history, 85th percentile speed, and other engineering judgments. Roadway segments with this recommendation are listed as “C” in Table 2.

As shown in Table 2, the following roadway segments recommend a change to the existing posted speed limit:

1. Alamitos Way, from Oleander Avenue to Descanso Avenue - based on the collected 85 th
percentile speed, the speed limit is recommended to be reduced from 30 MPH to 25 MPH.

2. Capalina Road, from Rancho Santa Fe Road to Pacific Street - based on the collected 85th percentile speed, the speed limit is recommended to be reduced from 35 MPH to 30 MPH.

3. Knoll Road, from Mission Road to San Marcos Boulevard - based on the collected 85th percentile speed, the speed limit is recommended to be raised from 35 MPH to 40 MPH.

4. Las Posas Road, from Grand Avenue to San Marcos Boulevard – based on the collected 85th percentile speed, the speed limit is recommended to be reduced from 45 MPH to 40 MPH.

5. Linda Vista Drive, from Western City Limits to W Linda Vista Drive – based on the collected 85th percentile speed, the speed limit is recommended to be reduced from 40 MPH to 30 MPH.

6. Linda Vista Drive, from Grand Avenue to Las Posas Road – based on the collected 85th percentile speed, the speed limit is recommended to be reduced from 40 MPH to 35 MPH.

7. Melrose Drive, from Rancho Santa Fe Road to San Elijo Road - based on the collected 85th percentile speed, the speed limit is recommended to be raised from 40 MPH to 45 MPH.
