CEQA Assessment - Active Transportation and Public Transit Analysis for the project in City of San Dimas

CEQA Assessment - Active Transportation and Public Transit Analysis

Potential impacts on public transit, pedestrian pathways, and bicycle facilities can be assessed using specific criteria. A significant impact is identified if a project conflicts with established policies, plans, or programs related to these facilities, or if it adversely affects their performance or safety. Thus, the Transportation Study (TS) should determine if the project aligns with adopted policies and assess its effects on the safety and functionality of active transportation and public transit facilities.

Transportation Impact Study Format

Each Transportation Study submitted to the City must include the following elements, unless otherwise approved by the City as not applicable:

1. Executive Summary
   This section provides a concise overview of key issues, including a project description, traffic generation potential, expected VMT impacts, a summary of mitigation measures, and any deficiencies in roadway Level of Service (LOS) along with proposed improvements.

2. Introduction
   The introduction should outline study procedures, describe the proposed project site and study area, detail existing and proposed land uses, and outline roadways and intersections. Required exhibits include a regional map and a site layout map.

3. Project Description and Location
   This section expands on the introduction, offering a detailed development scenario and project location, supported by illustrations such as a site plan, density, adjacent roadways, parking supply, traffic circulation, gross square footage, and number of units.

4. Methodology and Thresholds
   Describe the methodology for calculating LOS and VMT, including criteria for screening projects from VMT analysis. Identify the impact threshold for VMT and the City’s LOS standards for roadways and intersections.

5. LOS Analysis
   This analysis should include forecasts of traffic generation, distribution, assignment, and required improvements as detailed in the “Level of Service Analysis Procedure.”

6. On-site Parking, Access, and Circulation Analysis
   Refer to the On-Site Parking Analysis and Access and Circulation Analysis sections.

7. Active Transportation and Public Transit Analysis
   Refer to the Active Transportation and Public Transit Analysis section.

8. Vehicle Miles Traveled (VMT) Analysis
   Present the Project VMT per service population for all scenarios, including the project's impact on VMT, in tabular format. Document compliance with the City’s VMT screening criteria, identify all VMT impacts per the VMT Impact Thresholds, and outline proposed mitigation measures.

9. Appendix
   A detailed appendix must accompany the report, either included or provided separately if too large. This typically includes VMT and TDM calculations, traffic counts, LOS calculation sheets, signal warrants, accident diagrams, and sketches of proposed roadway improvements for the City’s review.
