a,7.A. - Page 35 and providing construction schedule notices; the Noise Disturbance Coordinator would work directly with an assigned City staff inember. Alternatively, the Noise Disturbance Coordinator could be employed by the City and funded by the applicant.) ■ Temporary Closure or Relocation of Child Care Center. If the project construction sequencing results in major outdoor construction activities occurring adjacent to the child care center after it is in operation, then the project sponsor, at its option, shall either temporarily close or relocate the child care center. Finding: Implementation of Mitigation 13-2 would reduce construction noise impacts, but because this project likely would be constructed in phases over a long period of time, nearby sensitive receptors would be subjected to repeated construction noise, thereby resulting in a significant unavoidable construction noise impact. Facts in Support of Finding: Implementation of Mitigation 13-2 would reduce project- facilitated demolition and construction noise to the maximum extent feasible by requiring rigorous, coordinated procedures, scheduling, and equipment standards. However, because the project is likely to be constructed in phases over several years, this intermittent noise impact on nearby sensitive receptors (e.g., residences) is considered significant and unavoidable. These facts are described and quantified in Draft EIR chapter 13 (Noise) on pages 13-1 through 13-20, which is hereby incorporated by reference. Impact: Impact 13-3: Project-Facilitated Groundborne Vibration Levels. Project- facilitated demolition and construction activities could generate substantial vibration (e.g., from potential pile driving) in the project vicinity. Mitigation: Mitigation 13-3. Reduce groundborne vibration levels during individual, location- specific future project demolition and construction periods by incorporating conditions in individual project demolition and construction contractor agreements that stipulate the following groundborne vibration abatement measures: ■ Restrict vibration-generating activity to between the hours of 7:00 AM and 7:00 PM, Monday through Friday. Prohibit such activity on weekends and holidays. ■ If pile driving is proposed, prepare a vibration study. If the vibration study shows that pile driving, including mitigation such as pre-drilling of pile holes, would cause vibration exceeding 0.5 inches/sec ppv for structurally sound buildings designed to modern engineering standards or 0.2 inches/sec for structurally sound buildings for which structural damage is a major concern, then pile driving shall not be conducted. Finding: Implementation of Mitigation 13-3 would reduce this potential intermittent and short-term project vibration impact to a less-than-significant level.
