The Project proposes to develop 46 condominium units east of Woodward Stre et, north of Mission Road and south of Vineyard Road in the City of San Marcos. Site access is proposed via one (1) full- access driveway to Woodward Street. The propos ed Project would require a General Plan Amendment but is consistent in terms of Section 3.11 under Threshold #2, General Plan Consistency in the Project’s Environmental Impact Report.

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.
