Subject: Woodward 46 Apartment Project
Linscott, Law and Greenspan, Engineers (LLG) has prepared this technical memorandum to provid e additional substantial evid ence supporting the use of the “Adjacency to High-Quality Transit” sc reening criterion for the Woodward 46 Apartment Project (hereafter referred to as the “Project”) to demonstrate that the Project qualifies for screening from a formal Vehicle Miles Traveled (VMT) analysis.
The Project proposes to construct 46 condo minium units east of Woodward Street, north of Mission Road and sout h of Vineyard Road in th e City of San Marcos. The Project is also located within walking distance of several amenities, including restaurants and cafes, a public library, a high-quality fitn ess center to the south, and the Twin Oaks Town Center to the west of the Project site, which includes a convenience store and other commercial businesses.
A VMT report was prepared for the Project under separate cover and is included in Attachment A. The Project was originally screened out based on its location within a High Quality Transit Area, per the map provided in the City of San Marcos Transportation Impact Analysis Guidelines (dated November 16, 2020) , which is included in Attachment B.
The Project is not located in a VMT efficien t area (15% or more below the base year average household VMT/capita) based on the applicable location-based screening map produced by SANDAG. The San Diego av erage regional VMT/capita is 18.9.
Using the SANDAG screening map for residential projects under per capita measurements, the Project is located in census tract 200.23 and would be expected to generate 17.8 VMT/capita. This equates to 94.0% of the regional average VMT/capita, as shown in the SANDAG screening map included in Attachment C .
Hence, the Project is 9% over the regi onal average and would have a potential significant VMT impact.

N:\3703 - Woodward 46 Apartment\Report\VMT Memo\VMT Memo.3703 June 2025 Revised.docx Figure A shows the location of the Project in re lation to the San Marcos Civic Center Transit Center, which is less than 0.30 miles away (approximately 1,200 feet from the nearest Project access to the sidewalk to the nearest access point to the transit station).
Therefore, the Project is located within a High Quality Transit Area (see Attachment B). The City's Transportation Impact Anal ysis Guidelines provides applicable VMT reduction percentages for projects in the City of San Marcos. According to the City’s Transportation Impact Analysis Guidelines, a project located within half a mile (or a ten-minute walk) of a major transit cente r can receive a VMT reduction of up to
14.4%. These VMT reduction percen tages are obtained from the San Diego Association of Governments (SANDAG) Mobility Management Guidebook (dated June 2019) and Mobility Management VMT Reduction Calculator Tool , which are included in Attachment D.
The formula used to calcula te the reduction percenta ge takes into account the difference in transit mode share with th e implementation of this strategy. Assuming that just 4% of the Project's residents, who previously lived in areas where transit was less accessible, will now use transit at th e Project site, thereby reducing single- occupancy vehicle use, this would re sult in a 10.9% VMT reduction, which is sufficient to lower the 17.8 VM T/capita in the Project's census tract to below the significant VMT impact threshold. Therefor e, applying this 10.9% reduction to the 94% VMT resident per capita for the censu s tract would result in the Project VMT being 83.1% of the regional mean which concludes the Project would not have significant VMT impact and validates the pr oject screening for adjacency to high quality transit. Attachment D includes the results from the VMT Reduction Calculator Tool.
Additionally, the Project incorporates the following features which complement the conclusion that the Project would have not have a significant VMT impact as they support active transportation modes:
Internal sidewalk connection to Woodward Street
The Project footprint is clustered to promote density and preserve open space Pedestrian safety features at the Project entry driveway (e.g., truncated domes) Street lighting addition to Woodward Street for pedestrian safety Figure B shows the Project site plan.

N:\3703 - Woodward 46 Apartment\Report\VMT.3703 March 2024.docx 8 3.0 VEHICLE MILES TRAVELED: OVERVIEW AND BACKGROUND
This section presents background on an evaluation of potential transportation impacts of the Project per the California Governor's O ffice of Planning and Research (OPR ) to implement California State Law Senate Bill (S.B.) 743 and the City’s adopted Transportation Impact Analysis Guidelines , December 2020.
3.1 VMT Background
VMT is a measurement of miles traveled by vehicl es within a specified re gion and for a specified time period. VMT measures the efficiency of the transportation network. VMT is calculated based on individual vehicle trips genera ted and their associated trip lengths. VMT accounts for two-way (round trip) travel and is often estimated for a typical weekday to measure transportation impacts.
3.2 Senate Bill 743
In September 2013, the Governor 's Office signed SB 743 into law, starting a process that fundamentally changes the way transportation imp act analysis is conduc ted under CEQA. These changes include the elimination of auto delay, leve l of service (LOS), and similar measurements of vehicular roadway capacity and traffic congestion as the basis for determini ng significant impacts.
The guidance identifies VMT as the most approp riate CEQA transportation metric, along with the elimination of Auto Delay/LOS fo r CEQA purposes statewide. The justification for this paradigm shift is that Auto Delay/LOS impacts lead to improvements that increase roadway capacity and therefore induce more traffic and greenhouse gas emissions.
In December 2018, after over five years of stakeholde r-driven development, the California Natural Resource Agency certified and adopted the CEQA St atute. As of July 1, 2020, the VMT guidelines are applicable statewide.
LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-22-3703 Woodward 46 Apartment Project
N:\3703 - Woodward 46 Apartment\Report\VMT.3703 March 2024.docx 9 4.0 VMT SIGNIFICANCE CRITERIA & METHODOLOGY
4.1 Local / Regional Agency Transition to SB743
The City of San Marcos adopted the Transportation Impact Analysis (TIA) Guidelines , November 2020 version, that provides signi ficance determination thresholds for VMT and VMT analysis methodologies. The City’s TIA Guidelines was utilized as the basis for this VMT analysis.
4.2 Screening Criteria
Based on the TIA Guidelines , the requirement to prepare a de tailed transportation VMT analysis applies to all land development pr ojects except for those that meet at least one of the provided screening criteria. A project that meets at least one of the screeni ng criteria listed below would be considered to have a less-than-significant impact due to the project or location characteristics. Small Projects (less than 110 daily vehicle trips)
Affordable Housing (100% deed restricted)
Local Serving Retail and Public Facilities (50,000 square feet gross floor area or less) Adjacency to High-Quality Transit. A high-quality transit area is defined as the one-half mile walkshed around either of the following:
o An existing major transit st op, defined as a site contai ning an existing rail transit station or the intersection of two or more bus routes with a combined frequency of service interval of 15 mi nutes or less during the mo rning and afternoon peak commute periods. In addition, a rail transit station must be within 0.25 miles of bus stops serving at least one bus route with individual service intervals no longer than 30 minutes during peak commute periods per route in order to qualify as a high-quality transit area.
o An existing stop along a high-quality transit corridor, defined as a corridor with fixed route bus service with combined service intervals (gaps between buses serving the corridor) no longer than 15 minutes during peak commute hours.
However, this presumption does not apply if the project:
1. has a floor area ratio (FAR) of less than 0.75;
2. includes more parking for use by residents, customers, or employees of the project than required by the City;
3. is inconsistent with the City’s current General Plan, as determined by the City; or, replaces affordable residential units with a smaller number of moderate- or high- income residential units.
Map-Based Screening (projects located in VMT efficient areas): Residential and employment projects that are proposed in areas that genera te VMT below adopted City thresholds can be presumed to have a less-than-significant tr ansportation impact and would not require a detailed VMT analysis. This determinat ion must be made using SANDAG’s online
LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-22-3703 Woodward 46 Apartment Project
N:\3703 - Woodward 46 Apartment\Report\VMT.3703 March 2024.docx 10 residential and employment VMT maps, which show census tracts in the city where the VMT is below the regional average. The following ty pes of projects could be screened out using this approach:
o Residential projects propos ed in census tracts with residential VMT per capita below the City’s threshold of exceed ing 85 percent of the SANDAG regional average
o Employment projects proposed in census tracts with work VMT per employee below the City’s threshold of exceed ing 85 percent of the SANDAG regional average
4.3 Mitigation Measures and Strategies for VMT Reduction If a project is not presumed to ha ve a less than significant VMT impact due to project characteristics and/or location, then it is cons idered to have a significant impact and will re quire mitigation measures and strategies.
LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-22-3703 Woodward 46 Apartment Project
N:\3703 - Woodward 46 Apartment\Report\VMT.3703 March 2024.docx 11 5.0 VMT ANALYSIS
Per the TIA Guidelines, a VMT analysis for CEQA purposes will not be required as the project is located within a high-quality transit area. The High-Quality Transit Areas map shows the Project site is within this area. The following is a discussion of the three items (listed in Section 4.2) that are potential caveats:
FLOOR AREA RATIO AND GENERAL PLAN
Per coordination with City staff, the Specific Plan requires a minimum floor area ratio of 0.75.
The proposed Project would requir e a General Plan Amendment but is consistent in terms of Section 3.11 under Threshold #2, General Plan Consis tency in the Project’s Environmental Impact Report.
PARKING
The Project proposes a total of 46 condominium units. Per the City of San Marcos Municipal Code, Chapter 20.340 , 108 parking spaces are required. A summary of the parking code requirements and calcul ations are shown in Table 5–1 . The project proposes to provide 108 parking spaces. Therefore, the project meets the parking requirements and does not exceed.

Appendix A contains the TIA Guidelines’ High-Quality Transit Areas map, excerpts from the City of San Marcos Municipal Code Parking Rate and floor area ratio calculation.
Therefore, based on the City’s TIA Guidelines, a VMT analysis is not requi red as the Project is located in a high-quality transit area. VMT impacts are presumed to be less than significant.

IMPACT ON VMT
Reduction of up to 14 % of project VMT
VMT reduction affected by:
Current transit mode share in project area.
Proximity and access to transit station.
Frequency of and accessibility provided by nearby transit service.
IMPLEMENTATION CONS IDERATIONS
Transit corridors that provide direct connections to the region’s downtown or major employment centers are
significantly more likely to attract new TOD compared
to transit lines that do not serve these destinations.
Walking and biking are essential to the success of TOD.
COMPLEMENTARY STRATE GIES

TRANSIT -ORIENTED DEV ELOPMENT
Transit -Oriented Development (TOD) refers to projects built in walkable areas that have easy access to public transit and typically offer a mix of uses, including housing, retail, offices, and/or community facilities. TOD should be built within a half -mile of a high -frequency rail transit station (e.g. , SPRINTER, COASTER, Trolley) and, at a minimum, incorporate adequate bike and pedestrian facilities that facilitate connections to and from transit, encouraging transit use and reducing single -occupancy vehicle use .

Description: Transit Oriented Development (TOD) refers to projects built in compact, walkable areas that have easy access to public transit, ideally in a location with a mix of uses, including housing, retail, offices, and community facilities. TODs are generally described as places within a 10 minute walk of a high‐frequency rail transit station (e.g. SPRINTER, COASTER, Trolley). They should, at a minimum, incorporate bike and pedestrian access to transit, thereby encouraging transit use and reducing vehicle travel.

Commute
Program
This measure consists of a variety of measures to reduce single- occupant vehicle commuting through an employer, such as carpool/vanpool programs, subsidized transit passes,
preferential carpool parking, bicycle facilities, and flexible work schedules. Unlike a mandatory program, this strategy does not require monitoring, reporting, or performance standards.
Note, this measure cannot be analyzed in combination with a mandatory employer commute program. In addition, separate commute demand management measures should not be
analyzed if already included under this measure.
