Statement of Facts and Findings Mitigation Measure LU -2: The Development Agreement that is required for implementation of the proposed project shall require outdoor signage consistent with AELUP Policy 3.2.4 to be posted within outdoor common or recreational areas on the proj ect site. The signage shall state the following: "Notice of Airport in Vicinity. This property is presently located in the vicinity of an airport, within what is known as an airport influence area. For that reason, the outdoor areas on the property may be subject to some of the annoyances or inconveniences associated with proximity to airport operations related to noise." Noise A. Facts Operation of the project has the potential to expose persons to noise levels in excess of standards established in the City's General Plan or noise ordinance. The project would install new stationary mechanical equipment such as HVAC units and exhaust fans for the new buildings, and the emergency generator for the onsite data center would be relocated and would be equipped with a sound enclosure specifically designed to muffle the noise of the generator, which would reduce noise volumes below the City's standards. To ensure appropriate location and /or noise reduction methods for HVAC equipment, the emergency generator, and any other machinery- related noise, Mitigation Measure NOI -1 would be implemented to adequately shielded or muffle noise from onsite equipment pursuant to City standards. Mitigation Measure NOI -1 would ensure that impacts related to mechanical equipment would be less than significant. 2. Constriction of the project has the potential to result in a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project. The project's estimated construction noise levels could exceed the existing daytime ambient noise levels at this noise - sensitive receptor by as much as 15 dBA. Therefore, Mitigation Measures NOI -2 through NOI- 6 are included, wlvch require the use of noise reduction devices and techniques during project construction, which include the use of noise barriers. The temporary noise impacts during project construction would be reduced to a less - than - significant level with implementation of Mitigation Measures NO'I -2 through N0I -6. B. Findings The City finds that: The mitigation measures listed below have been required for, and incorporated into the project, to ensure that the project's potential impacts related to noise remain less than significant, Mitigation Measures Mitigation Measure NOI -1: The Building and Safety Division shall confirm that the Building Plans and specifications stipulate that all new mechanical equipment that will be installed at the project site, including ventilation and air conditioning units, and the relocated emergency generator, shall be equipped with adequate acoustical shielding or muffling devices to ensure that noise levels will not The Hedlage Mixed use Pr.]W 33 ESA / 140730 Slaternent of Facts and Findings September 2015
