Pock Lane Residential Traffic Impact Study 4.4 INTERSECTION LEVEL OF SERVICE ANALYSIS- EXISTING PLUS PROJECT CONDITIONS The intersection LOS analysis results for Existing plus Project Conditions are summarized in Table 7. 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 continue degrade to LOS F in the p.m. peak hour, 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. With mitigation, the project would be consistent with level of service standards set forth under the San Joaquin General Plan. A peak hour signal warrant analysis was also conducted for the unsignalized intersection of Pock Lane & Mariposa Road, to determine if a traffic signal is warranted.A signal is not warranted at this intersection during either peak hour. Figure 9 shows projected turning movement volumes at all the study intersections for Existing plus Project Conditions. LOS and peak hour signal warrant worksheets are provided in Appendix D.
