r. LOS E during the PM peak hour under Cumulative Plus Project Conditions. Operations at this intersection can be improved to LOS C by optimizing the traffic signal timing to adjust for forecast changes in PM peak hour volumes. • Intersection 11:Hopyard Road/Stoneridge Drive—This intersection would operate at LOS F during the PM peak hour under Cumulative and Cumulative Plus Project conditions. Operations at the intersection can be improved to LOS E by optimizing traffic signal timing, but operations would not improve to within City of Pleasanton standards. Further mitigation was not identified due to the widening required and the presence of adjacent land uses abutting the intersection. • Intersection 13:Santa Rita Road/Stoneridge Drive—The addition of project generated traffic to Cumulative baseline conditions would result in this intersection degrading from LOS D to LOS E during the AM peak hour. During the PM peak hour,this intersection would operate at LOS E under both, Cumulative and Cumulative Plus Project conditions. Cumulative Plus Project AM peak hour operations at this intersection could be improved to LOS E by optimizing the traffic signal timing and modifying phasing. However, AM peak hour operations would not improve to within the City of Pleasanton's standard with the modifications. PM peak hour operations at this intersection can be improved to LOS D by optimizing the traffic signal timing to adjust for forecast changes in volumes. • Intersection 15:Hopyard Road/I-580 EB Ramp—This intersection operated at LOS F during the PM peak hour under Cumulative and Cumulative Plus Project conditions. Operations at this intersection can be improved to LOS C by optimizing the traffic signal timing to adjust for forecast changes in PM peak hour volumes. • Intersection 21:Santa Rita Road/I-580 EB Ramp/Pimlico Drive= During the PM peak hour, this intersection operates under LOS F conditions within Cumulative and Cumulative Plus Project scenarios.Operations at this intersection can be improved to LOS D by optimizing the traffic signal timing to adjust for forecast changes in PM peak hour volumes. • Intersection 24:Santa Rita RoadNalley Avenue—This intersection operates at LOS E during the PM peak hour under Cumulative and Cumulative Plus Project conditions. Operations at this intersection can be improved to LOS D by optimizing the traffic signal timing to adjust for forecast changes in PM peak hour volumes. • Intersection 26: Valley Avenue&Busch Road—The addition of project generated traffic to Cumulative baseline conditions would result in this intersection degrading to LOS E during the AM peak hour under Cumulative Plus Project Conditions. Operations at this intersection can be improved to LOS C by optimizing the traffic signal timing to adjust for forecast changes in AM peak hour volumes. • Intersection 27:Bernal Avenue/Valley Avenue/Stanley Boulevard—This intersection operates at LOS E during the PM peak hour under Cumulative and Cumulative Plus Project conditions. However,this intersection is an exempted gateway intersection. Signal timing optimization and/or adjustments would not achieve an acceptable level of
