from nighttime construction activity could exceed the FTA's nighttime construction noise criterion <br /> of 70 dBA Leq at off-site residential uses. As such, implementation of Project-Specific MM NOI-1 <br /> would reduce noise levels during nighttime concrete pours by at least 10 dBA. Project-Specific <br /> MM NOI-1 requires a nighttime construction control plan and implementation of construction <br /> techniques, including installation of temporary noise barriers or enclosures during Phases 2 and <br /> 3 to protect sensitive receptors to the north and west, use of mufflers on construction equipment, <br /> and placement of construction equipment away from sensitive receptors. Therefore, impacts to <br /> construction noise during nighttime concrete pours would be less than significant with mitigation <br /> incorporated. <br /> Cumulative Impacts: The Project would not result in cumulative impacts concerning noise, with <br /> the implementation of mitigation. <br /> Findings: The City finds that changes or alterations have been required in, or incorporated into, <br /> the Project, which avoid or substantially lessen the significant environmental effect as identified <br /> in the Final Supplemental EIR. Specifically, the City finds that Project-Specific MM NOI-1 (listed <br /> previously) shall be implemented to reduce potentially significant noise impacts resulting from the <br /> Project. (Draft Supplemental EIR, p. 4.9-32.) <br /> Explanation of the Rationale: The rationale and facts supporting the above finding are fully <br /> developed in Section 4.9, Noise, pages 4.9-36 through 4.2-44 of the Draft Supplemental EIR. The <br /> following presents a summary of that rationale: <br /> Construction activities associated with the Project and cumulative growth may overlap, resulting <br /> in increased construction noise in the Project vicinity. However, construction noise primarily <br /> affects the areas immediately adjacent to a construction site. Due to the distance and intervening <br /> structures, cumulative construction noise from related projects would not be perceptible. With <br /> exception of the Related Bristol Specific Plan Project,the related projects are located at distances <br /> well removed from the Project site. The Related Bristol Specific Plan Project is located directly to <br /> the east of the Project site of which construction of the area closest to the Project would not <br /> overlap (Related Bristol Specific Plan Phase 1 construction start 2026) with construction of the <br /> Project in the area directly adjacent(Project Phase 4 construction start 2036).The Related Bristol <br /> Specific Plan Project is anticipated to be completed in 2036. With the rapid attenuation of noise <br /> with distance, construction noise from the Project and Related Bristol Specific Plan Project would <br /> not combine to result in significant cumulative effects. The Project would implement Project- <br /> Specific MM NOI-1 to reduce noise levels during nighttime concrete pours by at least 10 dBA by <br /> requiring a nighttime construction control plan and implementation of construction techniques, <br /> including installation of temporary noise barriers or enclosures during Phases 2 and 3 to protect <br /> sensitive receptors to the north and west, use of mufflers on construction equipment, and <br /> placement of construction equipment away from sensitive receptors. In the unlikely event that <br /> nighttime concrete pours for both the Related Bristol Specific Plan Project and the Project occur <br /> on the same nights in the vicinity of each other, both projects would be required to obtain a permit <br /> from the City, including development of a nighttime construction noise control plan, as specified <br /> in the respective project-specific noise mitigation measures, which would reduce noise levels <br /> below the significance criteria.
