INTRODUCTION This report is the transportation deliverable for Task 6.2, CEQA Analyses, for the Irvington BART Station (the project). The purposes of the report are: • Present ridership and access mode forecasts to reflect the proposed Station Site Plan. • Evaluate the impact of the project on traffic operations in surrounding roadways. The traffic operations analysis also accounts for the potential impacts of the pedestrian and bicycle improvements under consideration. • Evaluate and recommend improvements to the pedestrian and bicycle infrastructure on key corridors providing access to the station. 1.1 REPORT ORGANIZATION This report is divided into the following four chapters: • Chapter 1 – Introduction provides an overview of this report and briefly describes the proposed Station Site Plan • Chapter 2 – Ridership Forecasting describes the ridership forecasting methodology and summarizes the results for the project • Chapter 3 – Traffic Forecasts and Operations Evaluation summarizes the existing traffic conditions in the station area, describes the process used to develop the traffic volume forecasts, and assesses the potential impacts of the project on traffic operations in 2040 • Chapter 4 – Active Access Comfort Evaluation evaluates the existing conditions of the transportation infrastructure for walking and biking in the station area and provides recommendations for active access improvements 1.2 PROJECT DESCRIPTION The proposed two-level, side-platform BART station design would feature an elevated concourse that spans across the BART and Union Pacific Railroad (UPRR) tracks. Station Site access would be provided from Osgood Road (east of the station), Main Street/High Street (northwest of the station), and Roberts Avenue/ Washington Boulevard (west of the station). Elevated walkways from multi-modal access facilities on the east and west side of the BART and UPRR tracks would be accessed from stairs and elevators. Key transportation elements of the Station Site Plan include the following: 1 BART WARM SPRINGS EXTENSION FINAL SUPPLEMENTAL EIR – ADDENDUM 2 July 2019 Irvington BART Station: Transportation Impact Study July 2019 • A pedestrian bridge from the southwest
