FP Oy Pleasanton standard, and there are no reasonable mitigation measures for this intersection. • Intersection 27:Santa Rita Road/I-580 EB Ramp/Pimlico Drive—This intersection would operate at LOS F during the PM peak hour under EPAP baseline and EPAP Plus Project conditions.The addition of project generated traffic to EPAP baseline conditions would result in increased average delay at this intersection while in LOS F operations. Under EPAP Plus Project Plus Extension Conditions, this intersection would improve to LOS E during the PM peak hour.This is an exempt intersection with LOS below the City of Pleasanton standard, and there are no reasonable mitigation measures for this intersection. • Intersection 24:Santa Rita Road/Valley Avenue—This intersection would operate at LOS F during the PM peak hour under EPAP baseline and EPAP Plus Project conditions.The addition of project generated traffic to EPAP baseline conditions would result in increased average delay at this intersection while in LOS F operations. Under EPAP Plus Project conditions, operations at this intersection can be improved to an average delay of 78 seconds per vehicle, decreasing delay from EPAP baseline conditions, by optimizing the traffic signal timing to adjust for changes in project generated traffic. Under EPAP Plus Project Plus Extension Conditions,this intersection would improve to LOS E during the PM peak hour. Cumulative (Year 2040) Conditions The Cumulative condition represents conditions in the 2040 horizon year, consistent with the City of Pleasanton travel demand model.To evaluate the potential effect of traffic generated by the proposed project on the surrounding street system,volume estimates representing Cumulative without Project Conditions were prepared. Traffic conditions without the project under this future scenario reflect traffic increases due to nearby and regional development along with background roadway network changes and street improvements. The forecasted Cumulative without Project Conditions traffic volumes were then used as the baseline to identify the project's effects on the operations of the circulation system.This chapter presents the results of the level of service calculations under Cumulative Conditions both with and without the Project. Cumulative (Year 2040) Circulation System Effects This subsection identifies the cumulative, long-term effects, of the addition of project generated peak hour trips on the operations of the local circulation system. Traffic volumes for Cumulative Conditions are comprised of Existing Conditions volumes plus traffic generated by anticipated local and regional land use growth. Cumulative conditions were forecast using the City of Pleasanton's travel demand model and reflect buildout of the city's General Plan and the general plans of surrounding communities.
