Each Transportation Study submitted to the City should include the following elements, unless a topic is not applicable. Items omitted as “not applicable” must first be approved by the City:
- Executive Summary
- Introduction
- Project Description and Location
- Methodology and Thresholds
- LOS Analysis
- On-site Parking, Access, and Circulation Analysis
- Active Transportation and Public Transit Analysis
- Vehicle Miles Traveled (VMT) Analysis
- Appendix
1. Executive Summary
This section should provide concise information on the major issues, including a brief project overview, discussion of traffic generation potential, expected VMT impacts, and a summary of mitigation measures. It should also summarize any roadway LOS deficiencies and proposed improvements.
2. Introduction
Include a detailed description of study procedures, an overview of the proposed project site and study area boundaries, existing and proposed site uses, and existing and proposed roadways and intersections within the study area (defined by the City). Required exhibits include a regional map showing the project vicinity and a site layout map.
3. Project Description and Location
Expand on the introduction, providing a detailed development scenario and specific project location. Exhibits should include a site plan, project density, adjacent roadways, on-site parking supply, proposed traffic circulation within the project, gross square footage, number of rooms/units, and other relevant descriptors.
4. Methodology and Thresholds
Identify the methodology used to calculate LOS and VMT. Include criteria for screening projects from project-level VMT analysis, if applicable. State the impact threshold for VMT and the City’s LOS standards for roadways and intersections.
5. LOS Analysis
Include the Traffic Generation Forecast, Traffic Distribution and Assignment, Traffic Analysis, and identify required improvements as described 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 analysis scenarios and the Project effect on VMT for all analysis scenarios. Data should be presented in tabular format. Document if the project meets the City’s VMT screening criteria. Identify all VMT impacts in accordance with the VMT Impact Thresholds and propose VMT mitigation measures.
9. Appendix
Include detailed appendix material as part of the report. If the main report is too large, provide the appendix under a separate, identifiable cover. Typical materials include VMT and TDM calculations, traffic counts, LOS calculation sheets, signal warrants, accident diagrams at high-accident locations, sketches of proposed roadway improvements, and other information necessary for the City's review.
