~l:HR St PC:tRS ra •a xrp+ratlpa Cpx SULraa rs Documentation: Fehr & Peers will document this information in a technical memorandum for the City to review. We will then work with the City Staff to determine the optimal allocation of general- versus medical-office uses to minimize impacts to the site's intersections with adjacent roads. Once the project trip generation is finalized, the trips will be assigned to the road network using the directions of approach and departure. TASK 4 -BASELINE TRAFFIC FORECASTS It is our understanding that the forecasts for the near-term and cumulative condition will be developed using the City's travel demand model. Dowling Associates will provide to Fehr & Peers AM and PM peak hour link- and intersection-level forecasts for the near-term and cumulative without and with project forecasts, in addition to model output for the Existing (2008) base year condition. We will review the model output to check reasonableness of the forecasts, and the assumed roadway network in the vicinity of the site. This scope assumes we will receive .dbf turns files and loaded network files. Using the traffic forecasts, Fehr & Peers will Furness the volumes to develop peak hour intersection turning movement forecasts. The forecasts will be adjusted to ensure volumes balance between adjacent intersections. Documentation: Fehr & Peers will document the peak hour intersection turning movement forecast and Furness procedures in a technical memorandum for the City to review. After their review and acceptance, the subsequent task "Impact Analysis" will occur. TASK 5 -IMPACT ANALYSIS The intersection peak hour level of service at each study intersection will be calculated using the 2000 Highway Capacity Manual method. Roundabout operations will be evaluated using aaSIDRA. The mainline segment of I-680 at Bernal Avenue will also be evaluated using the 2000 Highway Capacity Manual method. For four (4) intersections closest to the project site, the potential for vehicle queue spillback from the available vehicle storage will be evaluated using the Synchro/SimTraffic software. The impact analysis will be conducted for the following scenarios: Scenario 1: Existing Conditions -Existing volumes obtained from traffic counts and the existing roadway system configuration. Scenario 2: Near-Term No Project Conditions -Existing volumes plus traffic estimates for approved and pending developments and/or traffic increases due to regional growth (using the City of Pleasanton Travel Demand Model) and transportation system improvements anticipated to be completed, including improvements that are conditioned on approved development projects. The horizon year for this analysis will be confirmed with City staff. Scenario 3: Near-Term Project Conditions -Traffic volumes from Scenario 2 plus traffic estimated for the project. The roadway system will be the same as Scenario 2 plus additions proposed by the project. Scope of Work Page 2 - 5
