Facts in Support of Finding: This mitigation measure appropriately identifies the Basic Construction Mitigation Measures developed by BAAQMD that would be implemented through all construction contracts and specifications for the proposed project. Impact AIR -2: Operation of the proposed project would expose future residents of the project site to toxic air contaminants. Mitigation AIR -2: The following measures shall be implemented by the project applicant and approved by the City through the final design process to reduce TACs and particulate matter indoors to a level sufficient to achieve compliance with BAAQMD health risk thresholds: The project applicant shall provide an HVAC system with a control efficiency sufficient to result in a reduction of a minimum 80.0 percent of particulates of 2.5 microns or less, such as Minimum Efficiency Reporting Value (MERV)-13 filters or greater, for indoor air filtration systems . The ventilation system shall be certified to achieve the stated performance effectiveness from indoor areas. The project applicant shall locate all air intakes as far away from US 101 as feasible. The project applicant shall disclose to potential occupants of the project that the proximity of the project site to the freeway could result in increased long-term health risks. The disclosure shall indicate the specifications for the installed air filtration system. Finding: Implementation of Mitigation Measure AIR -2 would reduce the project - related impacts related to exposing future residents of the project site to toxic air contaminants to a less -than -significant level. Facts in Support of Findina: This mitigation measure appropriately identifies measures in accordance with best management practices to reduce potential TACs and particulate matters indoors and to disclose to potential occupants of the project's potential long-term health risks related to its proximity to the freeway. NOISE Impact NOI-1: The proposed project and the project variant would locate residential land uses in an area that, based on the City's Noise and Land Use Compatibility Guidelines, is generally considered an unacceptable noise environment for residential land uses. Mitiaation NOI-1: Prior to issuance of building permits, the applicant shall prepare an acoustical study that demonstrates how residential units will meet the habitable room noise insulation standard of 45 dBA CNEL. The residential units shall include design features such as the following, or others approved by the City after review of the acoustical study, to the extent necessary to meet the 45 dBA CNEL standard for each unit: • In order for windows and doors to remain closed, provide mechanical ventilation such as air conditioning. • Install windows and glass doors rated STC 33 or higher in all units within 170 feet of US 101.
