San Carlos Street Mixed-Use Development Transportation Analysis November 20, 2020 Executive Summary This report presents the results of a Transportation Analysis (TA) for the proposed mixed-use development located at 1530-1544 San Carlos Street. The project site consists of three parcels (APN 277-18-018, -019, -020) and is located south of San Carlos Street and east of Buena Vista Avenue in the City of San José. The project site is located within a designated Urban Village (West San Carlos) per the Envision San Jose 2040 General Plan. According to the Envision San Jose 2040 General Plan, the Urban Village strategy fosters: Mixed residential and employment activities that are attractive to an innovative workforce Revitalization of underutilized properties that have access to existing infrastructure Densities that support transit use, bicycling, and walking High-quality urban design The project site is currently occupied by two automobile sales lots, an approximately 2,250 square-foot restaurant and eight detached residential units. The project as currently proposed consists of 173 multi- family residential units and 18,242 s.f. of commercial space. However, the project could include up to 21,164 s.f. of commercial space. Therefore, this study conservatively evaluates the greater amount of commercial space (21,164 s.f.). A total of 189 parking spaces are provided within one ground-level and one below-ground parking level. The proposed project site will be accessed by one right-in/right-out driveway on San Carlos Street. Transportation Analysis Scope The transportation analysis of the project was evaluated following the standards and methodologies set forth in the City of San Jose’s Transportation Analysis Policy (Council Policy 5-1), the City of San Jose’s Transportation Analysis Handbook 2018, the Santa Clara Valley Transportation Authority (VTA) Congestion Management Program’s Transportation Impact Guidelines (October 2014), and by the California Environmental Quality Act (CEQA). Based on the City of San Jose’s Transportation Policy and Transportation Analysis Handbook 2018, the TA report for the project consists of a CEQA vehicle- miles-traveled (VMT) analysis and a supplemental Local Transportation Analysis (LTA). CEQA Transportation Analysis Scope The CEQA transportation analysis for the project consists a project-level VMT impact analysis using the City’s VMT tool and a cumulative impact analysis that demonstrates the project’s consistency with the Envision San Jose 2040 General Plan. Local Transportation Analysis Scope The LTA includes the evaluation of weekday AM and PM peak hour operations at a limited number of intersections for the purpose of identifying operational issues (queuing, signal operations, and potential Page | i 1530-1544 W. San Carlos Street Mixed-Use Development Transportation Analysis November 20, 2020 multi-modal issues) at intersections in the general vicinity of the project site. However, the determination of project impacts per CEQA requirements is based solely on the VMT analysis. CEQA VMT Analysis CEQA Transportation Analysis Exemption Criteria The City of San Jose Transportation Analysis Handbook identifies screening criteria that determines whether a CEQA transportation analysis would be required for development projects. The criteria are based on the type of project, characteristics, and/or location. If a project meets the City’s screening criteria, the project is expected to result in less-than-significant VMT impacts and a detailed CEQA VMT analysis is not required. The project site is located within a planned Growth Area (West San Carlos Urban Village) with low VMT per capita as identified by the City of San Jose. San Carlos Street, located along the north project frontage,
