The SEIR included a Statement of Overriding Considerations for two significant and unavoidable impacts: Impact 4.D-1: Development facilitated by the General Plan Amendment and rezoning has the potential to adversely change the significance of historic resources. The Irby-Kaplan-Zia and Pleasanton Mobilehome Park properties on Stanley Boulevard contain older structures that may be historic. Mitigation measures in the SEIR required that historic evaluations be conducted for the structures before they could be demolished. If deemed to be historic through these evaluations, the demolition of these structures to make way for new housing would be a significant and unavoidable impact. Staff notes that the Irby- Kaplan-Zia and Pleasanton Mobilehome Park properties were ultimately not included in the nine sites that were selected for multifamily housing. Impact 4.N-7: Development facilitated by the General Plan Amendment and rezonings could potentially add traffic to the regional roadway network to the point at which they would operate unacceptably under cumulative plus project conditions. Traffic generated by development facilitated under the proposed Housing Element on the potential sites for rezoning would not worsen any segment projected to operate acceptably to unacceptable conditions; however, it would increase the volume to capacity ratio (V/C) by more than 0.03 on two roadway segments projected to operate at LOS F: Sunol Boulevard (First Street) between Vineyard Avenue and Stanley Boulevard under Year 2015 and 2035 conditions; and Hopyard Road between Owens Drive and 1-580 under 2035 conditions. Based on the significance criteria, this is considered a significant impact. Existing development surrounding these roadways would need to be removed in order to widen them, rendering such widening infeasible. However, there are improvements that could be made to nearby parallel corridors which could create more attractive alternative routes and lessen the traffic volumes on Sunol Boulevard and Hopyard Road. A mitigation measure of the SEIR requires developers of the potential sites for rezoning to contribute fair-share funds through the payment of the City of Pleasanton and Tri-Valley Regional traffic impact fees to help fund future improvements to local and regional roadways. However, because the City cannot be assured that the collected regional funds would be spent to specifically improve the nearby parallel corridors as the regional funds are used by the regional agency, the traffic impact remained significant and unavoidable. Staff notes that the traffic impacts of the nine sites ultimately selected would be considerably less than the traffic impacts analyzed in the SEIR. A memo was prepared by FirstCarbon Solutions (attached as Exhibit D) to evaluate the currently proposed project. The memo concluded that potential environmental impacts from the current project would be substantially similar to or reduced as compared to those disclosed in the 2014 Addendum. As such, with the implementation of mitigation identified in the 2014 Addendum and discussed herein, the current project would not result in any impacts beyond those considered in the Supplemental EIR. Therefore, the 2014 Addendum, in combination with this memo, satisfies the requirements of CEQA for the current project and no further environmental analysis is warranted.
