EXHIBIT A 9.12.0 Noise 9.12.1 Long Term Noise Threshold: Would the Project result in a substantial permanent increase in ambient noise levels in the Project vicinity above levels existing without the Project? Finding: Less than significant impact. (DEIR, p. 4.8.17 through 4.8-22.) Facts in Support of Finding: While the Project's operation would generate some traffic -related noise, such noise would not constitute a substantial permanent increase in ambient noise levels in the Project vicinity above levels existing without the Project. Pursuant to the Noise Impact Analysis (Exhibit H to the DEIR), the Project would generate an increase of less than one dBA CNEL on the study area roadway segments, which is less than the relevant threshold. For the reasons discussed above and the reasons discussed in the DEIR, impacts associated with this issue would be less than significant, and no mitigation is required. (DEIR, p. 4.8.17 through 4.8-22.) 9.12.2 Public Airports Threshold: For a Project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the Project expose people residing or working in the Project area to excessive noise levels? Finding: No Impact. (DEIR, p. 2-7; Initial Study, pp. 49-50.) Facts in Support of Finding: The Project site is not located within an airport land use plan or within 2 miles of an airport. The closest airport to the Project site is John Wayne Airport, which is located over 6 miles to the south of the Project site. In addition, the Fullerton Municipal Airport is located approximately 9.35 miles to the northwest of the airport. Therefore, the Project would not expose people residing or working in the Project area to excessive noise levels related to airports. (Initial Study, pp. 49-50,) For the reasons discussed above and the reasons discussed in the DEIR and Initial Study, impacts associated with this issue would be less than significant, and no mitigation is required. (Initial Study, pp. 49-50.) 9.12.3 Private Airstrips Threshold: For a Project within the vicinity of a private airstrip, would the Project expose people residing or working in the Project area to excessive noise levels? Finding: No Impact. (DEIR, p. 2-7; Initial Study, p. 50.) Facts in Support of Finding: The proposed Project site is not located within the vicinity of a private airstrip and would not expose people residing or working in the Project area to excessive noise levels related to an airstrip. (Initial Study, p. 50.) For the reasons discussed above and the reasons discussed in the DEIR and Initial Study, impacts associated with this issue would be less than significant, and no mitigation is required.
