Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential cumulative impacts to a less-than-significant level: Mitigation Measure 6-2: Unacceptable Level of Service: Bernal Avenue/Stanley Boulevard. To mitigate an unacceptable level of service at the intersection of Bemal Avenue/Stanley Boulevard, the following measure should be implemented with the buildout of the General Plan: Add a third through-lane on the eastbotmd Stanley Boulevard approach. This mitigation would improve this intersection to V/C ratio 0.86, LOS D, during the impacted p.m. peak hour and sufficiently mitigate an unacceptable level of service. This mitigation measure is planned by the City and would be funded by traffic impact fees. SIGNIFICANT EFFECT Impact 6-3: Degradation to Unacceptable Level of Service: Isabel Avenue/Vineyard Avenue. Traffic generated by the development of the proposed project would degrade levels of service (without mitigation) at the unsignalized intersection of Isabel Avenue and Vineyard Avenue. Severe delay and congestion would be anticipated at the intersection. This impact would be considered potentially significant. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential cumulative and growth-inducing impacts to a less-than-significant level: Mitigation Measure 6-3: Unacceptable Level of Service: Isabel Avenue/Vineyard Avenue To mitigate an unacceptable level of service at the unsignalized intersection of Isabel Avenue/Vineyard Avenue the following measure should be implemented with the buildout of the General Plan and construction of the proposed project: Add a second lane on the southbound Isabel Avenue Approach. This lane would function as an exclusive right-turn lane. With mitigation, the intersection would operate at LOS B with an average delay of 8.7 seconds for the delayed movements during the impacted a.m. peak hour. This improvement is anticipated to be implemented when Isabel Avenue is widened to 4 lanes as part of the Measure B transportation projects. SIGNIFICANT EFFECT Impact 6-4: Freeway Traffic Operations. Trips generated by the proposed project, when combined with the cumulative development planned in the region, would contribute to unacceptable traffic operations on segments of Interstates 580 (I-580) and 680 (1-680).
