The purpose of the analysis is to compare the traffic conditions for the proposed land use entitlement to the existing land use entitlement. The project, as proposed, would include 72 townhomes, 64 apartments, a 23,450 square-foot shopping center, a 1,550 square-foot café, and a 2,610 square-foot daycare center at the southeast corner of the intersection at Fremont Boulevard and Peralta Boulevard. Existing land uses include a 43,468 square-foot shopping center, 7,843 square feet of restaurant uses, a 970 square-foot mini-warehouse, a single-family dwelling, and a vacant City fire station. The analysis also includes a separate evaluation of a project variant consisting of 72 townhomes, 90 apartments, and 24,450 square feet of retail space (including a 1,550 square foot café). The potential impacts of the project were evaluated relative to the level of service policies and methodologies applicable in the City of Fremont. The analysis also was conducted in accordance with the requirements of the Alameda County Congestion Management Agency (CMA), the administering agency for the Congestion Management Program (CMP) of Alameda County. Because the project is projected to generate fewer than 100 net PM peak-hour trips, the project is not required to conduct a CMA roadway segment analysis. The traffic analysis evaluated AM peak-hour traffic conditions at several intersections in the vicinity of the project site. The study intersections were selected in consultation with City staff. The study also includes an analysis of site access, on-site circulation and neighborhood issues. Project Trip Generation Trip generation for the project was estimated by applying to the project use and size the rates applicable to the proposed residential, retail and daycare uses. The site was given credit for the trip generating capacity of the existing approved uses (entitlement) on site. The trip generation for both the proposed and existing uses on site was estimated by applying the applicable Institute of Transportation Engineers’ (ITE) trip generation rates to the uses. The trip generation estimates for both the proposed project and the existing site uses were adjusted using trip reductions for internal trips, retail pass-by trips, and transit trips. After subtracting from the project trips the trips generated by the existing uses on site, and applying the aforementioned trip reductions for internal trips, pass-by trips and transit trips, the project is estimated to generate 125 net new trips in the AM peak hour and 12 net new trips in the PM peak hour. The project ii | P a g e Silicon Sage Mixed-Use Development TIA trip distribution was determined based on a select zone analysis using the City of Fremont Travel Demand Forecast Model. This was the model used to produce the city’s forecasts for its most recent General Plan Update. Because the project would cause a negligible increase in PM peak-hour traffic, PM peak-hour conditions were not evaluated off-site. Analysis of PM peak-hour conditions immediately around the project site were included in a focused site operations analysis. Signalized Intersection Level of Service Analysis Table ES-1 summarizes the results of the intersection level of service (LOS) analysis under existing, background, and cumulative conditions with and without the proposed project. The proposed project would not result in any significant impacts to the signalized study intersections. Under existing and background conditions with the proposed project, all signalized study intersections would operate at LOS D or better. Under cumulative conditions with and without the project,
