Vehicle Miles Traveled Analysis In response to Senate Bill 743 in 2013 (SB 743), the Office of Planning and Research (OPR) updated the California Environmental Quality Act (CEQA) guidelines to include new transportation-related evaluation metrics. Those updated guidelines identified vehicle miles of travel or VMT as the most appropriate metric to evaluate the environmental effects of a project from a transportation perspective and prohibited the use of delay-based metrics (such as level of service (LOS)) for the purposes of identifying transportation impacts under CEQA. The updated guidelines were finalized in December 2018, including a new Section 15064.3 in the CEQA Guidelines on VMT analysis for land use developments. The new guidelines took effect July 1, 2020. The City of Pleasanton has not yet formally adopted VMT analysis guidelines or thresholds to apply to land use projects for which it serves as the CEQA lead agency. Similarly, the Alameda County Transportation Commission (Alameda CTC) has not made any recommendations regarding VMT thresholds. In the absence of more specific local guidance, Governor's Office of Planning and Research (OPR) guidance, as documented in the December 2018 Technical Advisory 6, has been reviewed and concepts presented in the Technical Advisory have been applied to the proposed project, considering the intent of SB 743 which is to "promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses." The OPR Technical Advisory suggests certain numerical VMT thresholds for common land use categories, including residential, office, industrial, and retail. Generally, residential, office and industrial developments where the resulting VMT per capita is 15 percent below the regional average can be considered less-than-significant. The CEQA significance criteria presented in Chapter 1 of the Traffic Study (Appendix J of Exhibit D) prepared for the proposed project related to VMT were developed based on this guidance. The OPR guidance also suggests the use of screening criteria to assess whether land use development projects can be presumed to have a less-than-significant impact on VMT. Three of these screening criteria are relevant to the proposed project: 1 . Small Projects: Projects that generate fewer than 110 vehicle trips per day may be presumed to have a less-than-significant impact on VMT. 2. Map-Based Screening: Residential and office projects located in areas with low VMT based on maps created with existing VMT data may be presumed to have a less-than- significant impact on VMT. 3. Near Transit Stations: Projects within a half-mile of an existing major transit stop5 or an existing stop along a high-quality transit corridor6 may be presumed to have a less-than- significant impact on VMT, except in cases where the project: 5 A major transit stop is a site containing an existing rail transit station, a ferry terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods. 6 A high-quality transit corridor is a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.
