Pock Lane Residential Traffic Impact Study EXECUTIVE SUMMARY This report summarizes the results of the Traffic Impact Study (TIS) conducted for the proposed Pock Lane residential developments located at 2706 and 3009 Pock Lane in unincorporated San Joaquin County. The proposed project would construct 96 single family homes at 2706 Pock Lane and 108 single family homes at 3009 Pock Lane, for a total of 204 units. The purpose of this report is to evaluate traffic impacts on the surrounding transportation system with the proposed project.A focused VMT analysis of the proposed project was previously conducted for CEQA purposes and is summarized in this report. To evaluate the effects on the transportation infrastructure due to the addition of traffic from the proposed project, an LOS analysis was conducted to determine consistency with San Joaquin County plans and standards. Vehicle Miles Traveled TJKM conducted a VMT analysis using the SJCOG travel demand model, identifying and correcting an error affecting locations with schools. Using a new model run of the corrected travel demand model, the regional average is 23.6 average daily VMT per resident,with a significance threshold of 20.1 for residential developments. Based on baseline and baseline plus project model runs, the baseline average at the project location is 17.9 average daily VMT per resident, and the proposed project is expected to generate 14.6, below the significance threshold. The project is expected to cause a less-than-significant impact to VMT under CEQA. Project Trip Generation TJKM developed estimated project trip generation for the proposed project based on published trip generation rates from the ITE publication Trip Generation (11t" Edition).TJKM used published trip rates for the ITE land use Single Family Detached Housing (ITE Code 210) for this project.The proposed project is expected to generate 1,926 total daily trips, including 150 a.m. peak hour trips(38 in, 112 out) and 202 p.m. peak hour trips (127 in,75 out). Existing Conditions Under this scenario, all but one of the study intersections operate within applicable jurisdictional standards during both peak hours. At the stop controlled intersection of Pock Lane & Mariposa Road, the northbound (controlled) approach operates at unacceptable LOS E during the p.m. peak hour.A traffic signal is not warranted at this location. Existing plus Project Conditions Under this scenario, all but one of the study intersections would continue to operate within applicable jurisdictional standards during both peak hours.The intersection of Pock Lane & Mariposa Road would degrade to LOS F, with an additional 2.5 seconds of delay, constituting a potentially significant impact. This impact can be mitigated with the addition of a northbound right turn lane.A traffic signal is not warranted at this location.With mitigation, the project would be consistent with level of service standards set forth under the San Joaquin General Plan.
