Development facilitated by the General Plan Amendment and rezonings could potentially be affected by existing, stationary (non-transportation) noise sources that would exceed the applicable City of Pleasanton Municipal Code criteria. The SEIR evaluates the impact of the proposed project related to the exposure of residents to stationary (non-transportation) noise sources that would exceed the applicable City of Pleasanton Municipal Code criteria. Significance Before Mitigation: Significant Significance After Mitigation: Less than Significant Finding: Changes or alterations have been required in or incorporated into the Project that would avoid or substantially lessen the significant environmental effect as identified in the SEIR. Mitigation Measures 4.J-6a through 4.J-6c which are required in or incorporated into the Project, will reduce the significant environmental impact to a less than significant level. Facts in Support of Finding: The following facts and mitigation measures indicate that the impact will be reduced to less than significant. 1.Noise from stationary (non-transportation) sources in the vicinity of all the potential sites for rezoning could exceed the applicable 60 dB Lmax exterior noise exposure limit established within the City Municipal Code. Some areas adjacent to industrial/commercial areas could be subject to loading noise and late or 24-hour operations noise. 2.Implementation of Mitigation Measures 4.J-6a through 4.J- 6c set forth in Table 6-1 of the Final SEIR and listed in the MMRP will ensure that Impact 4.J-6 would be reduced to a less than significant level and are hereby incorporated by reference and described below. 4.J-6a: For all of the potential sites for rezoning the City shall require site-specific acoustical assessments to determine noise exposure, impact, and mitigation regarding non-transportation sources. Noise exposure shall be mitigated to satisfy the applicable City Code criterion using appropriate housing site design. 4.J-6b: For Site 14 the City shall require a site-specific acoustical assessment to determine noise from quarrying noise sources. Recommendations in the acoustical assessment shall be sufficient to satisfy the applicable City of Pleasanton 70 dB Ldn and 50/55 dB Lmax exterior and interior noise exposure criteria, respectively. 4.J-6c: For all of the potential sites for rezoning, the City shall require a noise disclosures and noise complaint procedures for new residents at the project site. The requirement shall include a) a disclosure of potential noise sources in the project vicinity; b) establish procedures and a contact phone number for a site manager the residents can call to address any noise complaints. Site(s) affected: Mitigation Measure 4.J-6a All Sites; Mitigation Measure 4.J-6b - Site 14; Mitigation Measure 4.J-6c -All Sites.
