For a project located within an airport land use X 4, 13, 14, plan, would the project expose people residing 15 or working in the project area to excessive noise levels? f. For a project within the vicinity of a private X 4, 13, 14, airstrip, would the project expose people 15 residing or working in the project area to excessive noise levels? EXPLANATION: a-d)Existing ambient noise in the vicinity of the project site is predominantly due to proximity to the San Leandro BART Station and tracks, vehicular traffic along San Leandro Boulevard, and noise from on-going railroad (SPRR) operations, A noise study conducted for the proposed project assessed the exterior noise environment of the subject properties, After project build out, the noise environment will be dominated by BART operations along the easterly portion of Site 2, by SPRR operations along the westerly portion of Site 2 and by a combination of both to the north and south of the project area. Aircraft -related noise is low and infrequent, with only occasional civil aircraft operations being audible for brief periods. Existing sensitive receptors in the vicinity of the proposed project include students at St. Leander's Church and School to the north of Site 1 on W. Estudillo Avenue. The proposed project could introduce new sensitive receptors into the project site because of The residential nature of the development proposed for Site 1. As described below in Section XV, Transportation/Traffic, implementation of the proposed project would result in a direct and indirect increase in residents and visitors to the project site over current conditions. The increased activity levels at the project site, in addition to traffic and operation of the proposed project, have the potential to increase noise levels in the vicinity of the project. This potential increase could impact both existing sensitive receptors, as well as new potential residents within the project area. However, the Noise Study conducted by Wilson lhrig & Associates, Inc. (July 15, 2008) predicted no significant net increases in future noise levels at either of the project sites, with incorporation of appropriate noise attenuation features into the project design. Mitigation Measure #24: Common outdoor use areas and courtyards on Site 1 that will contain residential land uses that are exposed to noise sources exterior to the project shall be provided with noise mitigating design features, such as architectural sound barriers and other noise mitigation set forth in the Wilson Ihrig & Associates, Inc. Noise Study (July 15, 2008) in accordance with CCR Title 24. Public or private balconies are exempt from this requirement pursuant to the Downtown San Leandro TOD Strategy EIR (September, 2007). f) Neither Site 1 or 2 is located within the vicinity of a public airport or private airstrip. Oakland International Airport is located approximately 2.1 miles northwest of the project site. The project site (Sites 1 and 2) are slightly outside the airport's general referral area and well outside the designated noise zone. The effects of any airport -related noise could be considered a potentially significant impact on new residents due to the residential nature of the proposed project. There are no new impacts beyond what was analyzed in the Downtown San Leandro TOD Strategy EIR that was certified in 2007. Cornerstone at San Leandro Crossings Initial Study 21 March 2009
