City of Pleasanton—Additional Housing Sites Rezonings Project <br />Addendum CEQA Guidelines Section 15164 Addendum <br /> <br /> <br />112 <br />c) Excessive Noise Levels from Airport Activity <br />Would the project: For a project located within the vicinity of a private airstrip or an <br />airport land use plan or, where such a plan has not been adopted, <br />within two miles of a public airport or public use airport, would the <br />project expose people residing or working in the project area to <br />excessive noise levels? <br />Summary of Prior FEIR <br />According to the Prior FEIR, future development under the General Plan <br />would not expose people living or working in the Planning Area to excessive <br />noise from the Livermore Municipal Airport or any private airstrip. Existing and <br />projected airport operations are driven by regional aviation demand rather <br />than by the City’s growth, and any increases in single-event aircraft noise <br />would occur regardless of General Plan buildout. While some existing <br />residences may experience occasional aircraft noise, new development <br />near the airport would be required to incorporate noise-attenuation <br />measures consistent with General Plan policies, including limits on interior <br />noise levels and design standards for areas affected by aircraft or rail noise. <br />Because the General Plan includes policies requiring mitigation for new <br />sensitive uses and because airport-related noise levels are not expected to <br />increase as a result of the project, implementation of the General Plan would <br />result in less than significant impacts related to airport or airstrip noise <br />exposure. <br />Proposed Project Analysis and Conclusion <br />Consistent with the Prior FEIR, the proposed sites are located well outside any <br />airport’s 60 dBA CNEL noise contours and are not located within an ALUCP <br />area because they are located more than 3 miles from the Livermore <br />Municipal Airport. As a result, future development on these proposed sites <br />would not expose persons residing or working at the sites to noise levels from <br />airport activity that exceed normally acceptable standards. Therefore, <br />impacts would be less than significant, and the proposed project would not <br />result in a new or more severe adverse impact that was not previously <br />identified and disclosed in the Prior FEIR. No further analysis is required. <br />Conclusion <br />With regards to Noise, the Addendum demonstrates that: <br />1. No new or more severe impacts related to the proposed project or its <br />site have been identified.
