PUD-136, Mall Residential Project Planning Commission 28 of 34 Parking Pursuant to State Density Bonus Law, because the project is located near a major transit stop and would provide more than 20 percent low-income units, the City may not impose a parking ratio, inclusive of disability and guest parking, of more than half a parking space per unit. (See Cal. Gov’t Code § 65915(p)). Accordingly, 180 parking spaces are required (360 units x 0.5 spaces per unit = 180 parking spaces). Notwithstanding the ability to reduce required parking, the applicant has not asked to exercise these provisions. Instead, the project will provide more than double the required amount of parking spaces for a total of 473 total parking spaces, which will allow approximately 1.3 parking spaces per unit and a surplus of 293 parking spaces. Designated guest spaces would be provided in surface-level parking spaces within the motor-court area and in unassigned parking spaces within the parking structure. Therefore, adequate on-site parking would be provided. Bicycle Parking The Design Guidelines require approximately 0.6 bicycle spaces per unit (long-term storage) and two bicycle spaces for every 50 units (short-term storage/bike racks). For 360 units, 230 bicycle spaces (214 long-term and 16 short-term) are required. The project would provide 230 bicycle spaces within a designated area in the parking structure. Therefore, adequate on-site bicycle parking would be provided. Noise External noise sources that could affect the subject site include traffic noise from Interstate 580 to the north, Interstate 680 to the east, and adjacent City streets, and noise from adjacent land uses (which consist mainly of office and commercial uses). Housing Element Mitigation Measure 4.J-5c requires a demonstration that sensitive areas onsite would not be exposed to traffic noise in excess of 65 dBL. The noise study prepared by the applicant (Exhibit B) determined the sensitive areas to be studied were the courtyards and rooftop deck. The noise study concluded those areas would not be exposed to noise levels above 60 dBL provided a sound barrier is installed around the perimeter of the roof top deck area. That barrier may include decorative glass complementary to the building design. A condition of approval has been included requiring this barrier be shown on the plans submitted for permits. Housing Element Mitigation Measure Mitigation Measure 4.J-5b, requires a demonstration the project would meet the City’s 45 dBL interior noise standard. It is anticipated normal construction methods and requirements would allow the proposed building to comply with this standard. A condition of approval requires information be submitted at the building permit plan check stage sufficient to determine this standard would be met. Noise Impacts on Adjacent Properties The project would generate added urban noise, such as traffic, loading and unloading of delivery trucks, etc. However, given the existing noise levels produced by nearby street and freeway traffic and the existing commercial and office uses in the area, noise levels would not change substantially from that currently experienced in the area . Construction equipment would be required to meet DMV noise standards and be equipped with muffling devices. Once constructed, the operation of the project would be required to meet the City’s noise ordinance, which stipulates the project cannot produce a noise level more than 70 dBA at any point outside of the property plane. The project, based on its proposed residential use is not expected to generate any unusual sources of noise.
