MITIGATION MONITORING AND REPORTING PROGRAM FOR THE KAISER SAN LEANDRO MEDICAL CENTER /MIXED-USE RETAIL DEVELOPMENT PROJECT Environmental Impact Mitigation Measures Monitoring Responsibility Implementation and Monitoring Timeline achieved. Recommended vibration reduction measures provided by the site-specific engineering assessment shall be incorporated into the design and construction of the proposed project. These reduction measures could include pile driving techniques that have a lower potential for vibration impacts such as vibratory pile driving, pre-drilled pile holes, etc., as recommended by the consultant. The effectiveness of the vibration control measures shall be verified by vibration monitoring measurements during pile-driving activities. NO-3. New on-site sensitive receptors at NO-3.1 Require More Detailed Acoustical Analysis For Multi-Family Housing Or the Kaiser Medical Center and the Mixed- Hotel Uses. Use Retail Development could be exposed to noise above acceptable levels Per the City of San Leandro General Plan Policy 36.03, new development near an for multi-family residential units, which arterial shall be required to incorporate site planning and architectural design would result in a potentially significant measures that reduce the exposure of future building occupants to traffic noise. The impact. Additionally, Build-Out of the project sponsor of the Mixed-Use Retail Development shall have an acoustical Kaiser Medical Center would locate analysis prepared for the site by a qualified acoustical engineer to ensure that hospital facilities closer to I-880, thereby feasible site planning and architectural design measures are incorporated into the potentially exposing sensitive receptors to residential or hotel areas to reduce exterior noise.levels per the City General Plan. noise above acceptable levels. Measures to achieve acceptable noise levels may include adjusting the configuration of the residential or hotel buildings and placing exterior living areas such as balconies away from high traffic roadways. Recommendations from the report shall be submitted to the City for approval prior to issuance of a building permit. NO-3.2 Provide Exterior-To-Interior Noise Reduction Features For Phase 1 And Build-Out Of The Kaiser Medical Center To Meet An Interior Noise Standard Of 45 dBA. Prior to the City's issuing building permits, the project applicant (Kaiser) shall submit to the City noise analyses prepared by a qualified acoustical engineer that demonstrate that the proposed hospital structures will include adequate exterior-to- interior noise reduction features to meet interior noise level standards of 45 dBA CNEL for patient areas. Noise reduction features may incude, but are not limited to, building siting, upgraded insulation, sound-rated windows and doors, sound-rated exterior wall assemblies, and acoustical caulking. San Leandro Planning Services Division, pursuant to required subsequent environmental review for the mixed-use retail development site San Leandro Building and Safety Services Division At such time a development plans for the mixed-use retail development site are proposed Prior to the City's issuing building permits, review the noise analyses to ensure that proposed hospital structures will include adequate exterior-to-interior noise reduction features to meet interior noise level standards. of 45 dBA CNEL for patient areas.
