SimTraffic to capture the effects of queuing between intersections. Fehr & Peers will analyze the remaining 12 intersections in Synchro as these intersections are farther away from the interchange and unlikely to be directly affected by congestion spilling back from that interchange. Fehr & Peers will conduct the freeway segment and ramp analysis consistent with the IHSP DEIR and other Redwood City studies analysis for the locations listed above. In addition to the traffic analysis, Fehr & Peers will qualitatively describe pedestrian, bicycle, and transit facilities in the study area, including in the Inner Harbor area and connections between the project site and Downtown Redwood City. Task 3 — Proiect Travel Demand Project travel demand characteristics include trip generation, distribution, and assignment. Fehr & Peers will summarize the trip generation based on a Project Description and Site Plan provided by the City. Fehr & Peers will also use Mainstreet (same as MXD+ applied to the IHSP DEIR), our proprietary trip generation tool, to estimate potential reductions in vehicle trips that may be appropriate based on the local mix of land uses, demographics of the neighborhood, and proximity to transit. Fehr & Peers will summarize total vehicle trips associated with the Project. Using a similar trip distribution and trip assignment patterns used in the IHSP DEIR, Fehr & Peers will assign vehicle trips to the roadway network. This will include the study intersections and freeway segments and ramps listed above. Fehr & Peers will prepare two versions of the trip assignment under Existing Plus Project conditions — (1) without the Blomquist Extension, (2) with the Blomquist Extension. Fehr & Peers will assume the Blomquist Extension will be in place under all Cumulative scenarios. For all With Blomquist scenarios, Fehr & Peers will assume the intersection of Maple Street / Blomquist Street will operate as a single lane roundabout. Task 4 — Existino Plus Proiect Conditions Fehr & Peers will add the project -generated vehicle trips developed in Task 3 to the existing conditions traffic volumes developed in Task 2 to create Existing Plus Project Conditions traffic volumes. Fehr & Peers will complete an impact assessment by comparing the results of Existing Plus Project Conditions to the Existing (no Project) Conditions for the 18 study intersections and two future project driveways. Identification of impacts will be determined by comparing the results to the City's Significance Criteria presented in the Redwood City General Plan. Fehr & Peers 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 5 — Cumulative Conditions Fehr & Peers will use Cumulative (year 2040) forecasts previously prepared for the IHSP DEIR and US 101/SR 84 Interchange Improvement Project to create Cumulative intersection turning movement forecasts for the nine overlapping study intersections with that study. All freeway segments and ramps were included in that study as well. Fehr & Peers will use the same C/CAG model as the IHSP DEIR to develop AM and PM peak hour turning movement forecasts for the 10 new study intersections not covered in the IHSP DEIR. To create Cumulative No Project turning movement forecasts for the nine overlapping intersections and all freeway segments and ramps, Fehr & Peers will use the IHSP DEIR Page 22 of 26 REV: 11-08-17 PR ATTY/AGR.2017.262/ESA / Harbor View Project
