City of Santa Ana -Park View at Town and Country Manor Noise Draft EIR One or more method /s for reducing vibration from pile drivers as provided in Chapter 8 of the Caltrans Transportation- and - Construction- Induced Vibration Guidance Manual shall be implemented such that groundborne vibration shall not exceed 0.5 PPV at any existing sensitive receptor. A detailed approach for reducing groundbome vibration shall be provided to the City of Santa Ana as part of the construction noise mitigation plan required in Mitigation Measure N -1, to be submitted at the time of the grading permit application. Level of Significance After Mitigation Less than significant. Permanent Increase in Ambient Noise Levels Impact 4.5 -3 The project would not result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project. [CEQA Noise Threshold 11(c)] Impact Analysis This impact discussion analyzes the potential for a substantial permanent increase in ambient noise levels in the project vicinity associated with operation of the proposed project, including impacts related to offsite vehicular noise and exposure of neighboring land uses to stationary noise. The ongoing operation of the proposed project would be affected by long -term ambient noise sources. Potential noise impacts associated with the operations of the proposed project are the result of project - generated vehicular traffic on project - vicinity roadways, along with impacts from community noise on the project site. Community Noise Sources of stationary noise from the project site may include typical community noise such as dogs barking, loud conversation, and car doors slamming which is considered intermittent, and would not represent a substantial contribution to the ambient noise levels. Noise from community activities would not be expected to result in a substantial increase in noise levels or exceed any applicable noise standards. Noise from community activities would not expose the future receptors at the project site to substantial noise levels. Likewise, the proposed residences are not expected to generate noise levels that would affect existing sensitive receptors. Therefore, impacts would be less than significant. Vehicular Noise Long -term noise impacts would result from vehicle traffic associated with the project. City of Santa Ana noise standards are established in the City of Santa Ana General Plan Noise Element (2000), similar to the State of California Office of Noise Control model element guidelines, upon which most standards are now based.
