Therefore, offsite noise impacts associated with project - related traffic would be <br />less than significant. <br />On -Site Equipment Noise. The project site is currently partially developed with an existing <br />Buddhist temple and associated support structures located on the site. The closest existing noise - <br />sensitive land uses are the single family homes immediately to the east and an existing Baptist <br />church located immediately to the north, and multi - family residences located immediately to the <br />west across Sullivan Street. HVAC units could be included in the proposed project. HVAC units could <br />be located as close as 100 feet from the closest existing noise - sensitive land use. The specific <br />manufacturer and model of the HVAC units have not yet been determined. However, these units will <br />be selected with the relevant City and building standards as part of the performance specifications <br />(i.e., acoustically engineered and tested by the manufacturer to ensure that the noise standards <br />would not be exceeded). However to assure that noise from HVAC units would not impact nearby <br />sensitive land uses, Mitigation Measure NOI -2 will be included to assure that noise impacts would be <br />less than significant. <br />Mitigation Measure NOt -2: All HVAC units located on any portion of the property will be screened <br />by solid walls, on all side to provide effective acoustical as well as visual screening. <br />The Bat Nha Buddhist Meditation Center 3-73 June 2013 <br />Initial Study /Mitigated Negative Declaration 31 C -127 ICr 0021512 <br />
