Task 4-5 – Cumulative Conditions Fehr & Peers will review recent studies conducted within the study area, including South Main Street and Harbor View projects, to develop a Cumulative No Project turning movement forecast. We will use the same C/CAG model runs from the South Main Street and Harbor View projects to develop AM and PM peak hour freeway segment and ramp forecasts. Fehr & Peers will complete an adverse effects assessment by comparing the results of Cumulative Plus Project Conditions to the Cumulative No Project Conditions. Identification of impacts will be determined by comparing the results to the City’s significance criteria. We will identify mitigation measures for significant impacts and discuss feasibility and implementation factors with City Staff for comment and concurrence prior to completing the study. Task 4-6 – Multimodal Analysis The Gatekeeper project is anticipated to require a qualitative evaluation of the project’s potential adverse or beneficial effects on transportation facilities and services related to pedestrians, bicycles, transit. This will include conceptual recommendations consistent with multimodal improvements identified in RWCmoves, the El Camino Real Corridor Plan, other relevant plans. Task 4-7 -Rail Crossings The existing at-grade crossings are located at Whipple Road, Brewster Avenue, Broadway, Maple Street, Main Street, and Chestnut Street. As part of this task, we will develop a VISSIM model to evaluate operations at the six existing at-grade rail crossings and the intersections directly east and west of the crossings, which include the following eleven locations: 1. Whipple Avenue/Arguello Street 2. Whipple Avenue/El Camino Real 3. Brewster Avenue/Arguello Street 4. Brewster Avenue/El Camino Real 5. Marshall Street/Arguello Street 6. Broadway/El Camino Real 7. Maple Street/Main Street 8. Maple Street/Lathrop Street 9. Main Street/Beech Street 10. Chestnut Street/Heller Street 11. Chestnut Street/Main Street The City is currently considering several grade separation alternatives, including what is known as Alternative 1 (grade separation at all six locations) and Alternative 3 (grade separation only at Whipple Avenue and Brewster Avenue, with the Broadway crossing closed to vehicular access). As part of this task, we will develop a VISSIM model under Cumulative No Build, Cumulative plus Alternative 1, and Cumulative plus Alternative 3 scenarios. The Cumulative No Build scenario will include both the Transit District and Gatekeeper projects. We will work with the City to determine which transit service improvements, such as High Speed Rail, we should account for in the rail schedule/gate down time. To the extent feasible we will utilize information and data collected from other relevant City studies, as well as build off the VISSIM model developed for the High-Speed Rail project and the South REV: 06-23-21 MI ATTY/AGR.2021.150/Environmental Sciences Associates (Gatekeeper Projects) (Page 47 of 58)
