the minimum parking requirement for Site 1 is 426 parking spaces (376 spaces for the 251 units, 8 spaces for the live/work units, 25 visitor parking spaces for the 255 total units, and 17 spaces for the 5,700 square-feet of retail space). As proposed, Site 1 will provide 435 parking spaces (420 on-site parking spaces, including all angled parking spaces, and 15 street parking spaces — located on the east side of Willow Road). Site 2: With 247 residential units, four live/work units, and 251 total units that require visitor parking (247 residential plus four live/work units), the minimum parking requirement for Site 2 is 403 parking spaces (370 spaces for the 247 units, 8 spaces for the live/work units, and 25 visitor parking spaces). As proposed, Site 2 will provide 405 on-site parking spaces and, therefore, would exceed the parking requirements. Staff notes that the on-site angled parking on Gibraltar Drive is included in the 405 parking count. Noise The project applicant prepared site-specific acoustical studies to determine what, if any, special building treatments would be necessary to ensure an appropriate indoor noise level in the proposed residential units. The study, included as Appendix D in the Mitigated Negative Declaration (Exhibit M), accounts for noise emanating from various sources, including nearby roadways (including 1-580), BART, and the Livermore Municipal Airport. The study provides detailed recommendations regarding building materials and mechanical systems to ensure that interior noise levels in the proposed new residential units do not exceed applicable standards. The recommendations are location-sensitive; units closer to noise sources require more noise attenuating materials to comply with the applicable standards. The 2005-2025 General Plan Environmental Impact Report (EIR) acknowledged the potential for development consistent with the General Plan to result in increased exterior noise. The main noise source associated with new development was found to be traffic. The General Plan EIR analyzed locations in the City where significant noise increases would occur as a result of General Plan related growth and included mitigation measures reducing all such impacts to a less-than-significant level. Program 1.2 of the General Plan Noise Element stated that vibration sensitive land uses proposed to be located near railroad tracks should be evaluated for compatibility in a site-specific vibration analysis using the Federal Transit Administration's (FTA) vibration impact criteria. As stated in the January 2011 Mitigated Negative Declaration for the Hacienda TOD Standards and Design Guidelines, sensitive land uses proposed for areas near the BART station need to be examined for potential vibration effects. The report concluded that vibration from passing BART trains would not expose people to significant levels of vibration. The shortest distance between the project sites and the BART rail alignment is approximately 650-feet. The FTA's screening criteria for vibration assessment stipulate that residential projects within 200-feet of a rail rapid transit line should be examined more closely through a vibration study to determine if any vibration effects would occur. Beyond the screening distance, vibration effects are assumed not to be significant. Furthermore, construction is not anticipated to require pile driving, and therefore no project specific construction-period vibration study would be required. The City's General Plan requires that outdoor recreation areas not exceed 60 dB Ldn and that indoor noise levels not exceed 45 dB Ldn. Staff notes that the outdoor noise standard applies to the common outdoor recreation areas such as pools, spas, play areas, seating areas, etc., PUD-85-08-12D, PUD-81-30-86D, and P11-0856 Planning Commission 17of25
