Therefore, impacts would continue to be less than significant, and no mitigation is necessary, consistent with the Prior EIR. There are no proposed changes, new circumstances, or new information that would cause new or more severe impacts. Therefore, there are no environmental effects that are peculiar to the proposed project or the parcels on which the proposed project would be located. Impacts would be less than significant and the proposed project would not result in a new or more severe adverse impact that was not previously identified in the Prior EIR. d) Hazardous Materials Sites Prior EIR Conclusions The Prior EIR found that two sites proposed for development are known to have contained or been adjacent to a hazard materials release or contamination that has not been fully remediated. It was determined that development on sites that have been identified as requiring further site characterization and/or remediation work would be required to ensure that construction activities would not expose people or the environment to adverse effects. Tab le 4.G-1 in the Prior EIR identifies properties in the vicinity of the residential sites that are on the Cortese List. Site 3, which contains the project site, is not in the vicinity of any of the listed sites. Therefore, the Prior EIR determined that development on the site relevant to the proposed project would be less than significant in relation to hazardous materials sites. Analysis of Proposed Project The project-specific Phase I ESA prepared by APEX Companies (Appendix F) indicated that the project site is not listed on any hazardous material databases. As described above, no known contamination exists on the project site. In the event that contamination is discovered, General Plan Public Safety Element Policy 17, which requires that any contamination identified on-site must be remediated prior to development, would be in effect. Therefore, impacts would continue to be less than significant, and no mitigation is necessary, consistent with the Prior EIR. There are no proposed changes, new circumstances, or new information that would cause new or more severe impacts. Therefore, there are no environmental effects that are peculiar to the proposed project or the parcels on which the proposed project would be located. Impacts would be less than significant and the proposed project would not result in a new or more severe adverse impact that was not previously identified in the Prior EIR. e) Airports Prior EIR Conclusions The Prior EIR found that several of the potential sites for housing development under the Housing Element are located within the boundaries of the Alameda County Airport Land Use Policy Plan’s General Referral Area, which is coterminous with the Alameda County Airport Land Use Commission (ALUC) Hazard Prevention Zone. In addition, some of the potential sites for housing development
