City of Pleasanton—City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update Draft Program EIR Executive Summary FirstCarbon Solutions ES-21 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/EIR/3 - Draft/21480022 Sec00-03 Executive Summary.docx Impacts Mitigation Measures Level of Significance After Mitigation Impact LAND-2: Development consistent with the Housing Element Update, rezonings, and General Plan and Specific Plan Amendments would not cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. No mitigation is necessary. Less than significant impact. Section 3.11—Noise Impact NOI-1: Development consistent with the Housing Element Update, rezonings, and General Plan and Specific Plan Amendments could generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the potential sites for housing in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. MM NOI-1: Stationary Source Noise Impact Reduction Measure Prior to issuance for entitlements for a project, for any development project on potential sites for housing that would include any noise producing mechanical systems located within 25 feet of a property line, the project applicant shall retain a Noise Specialist to conduct a site- specific project-level noise analysis to evaluate compliance with Section 9.04.030 of the Municipal Code, which prohibits noise levels in excess of 60 A-weighted decibel (dBA) at any point outside the property plane. If the analysis identifies that proposed mechanical system operations could result in an exceedance of the City’s noise performance standards, then specific measures to attenuate the noise impact shall be outlined in the analysis. The analysis shall be submitted to the City’s Building and Safety Division for review and approval prior to issuance of building permits. The final noise-reduction measures shall be included on all final construction and building documents and/or construction management plans and submitted for verification to the City. Specific measures may include, but are not limited to, the following measures or design features: • The project applicant shall utilize quieter mechanical systems that would not result in an exceedance of the City’s operational noise standards. • The project applicant shall enclose mechanical systems in a sound- attenuating structure or shall install sound barriers adjacent to the proposed system that would reduce operational noise levels to not exceed the City’s noise performance standards as measured at the property line. • The project application shall relocate the proposed mechanical system further from property line to reduce operational noise levels to not exceed the City’s noise performance standards as measured at the property line. Less than significant impact with mitigation incorporated.
