ATTY/RESO.0035/CC RESO CERTIFYING FINAL EIR – 1548 MAPLE REV: 04-30-18 PR Page 14 of 49 Mitigation NOI-2: The project contractor shall implement the following measures during construction of the proposed project: • Equip all construction equipment, fixed or mobile, with properly operating and maintained mufflers consistent with manufacturers' standards. • Place all stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the active project site. • Locate equipment staging in areas that would create the greatest possible distance between construction-related noise sources and noise-sensitive receptors nearest the active project site during all project construction. • Ensure that all general construction related activities are restricted to between the hours of 7:00 a.m. and 8:00 p.m. on weekdays. No construction shall be permitted on weekends or holidays. • Post a sign at all entrances to the work site prior to commencement of the work for the purpose of informing all contractors and subcontractors and all other persons at the property of the basic limitations upon noise and construction activities provided in the noise ordinance. • Designate a “disturbance coordinator” at the City of Redwood City who would be responsible for responding to any local complaints about construction noise. The disturbance coordinator would determine the cause of the noise complaint (e.g., starting too early, bad muffler) and would determine and implement reasonable measures warranted to correct the problem. Finding: Mitigation Measure NOI-2 would reduce the project-related impacts related to noise levels in the project vicinity as a result of construction activities to a less-than- significant level. Facts in Support of Finding: This mitigation measure appropriately identifies measures consistent with best management practice to reduce ambient noise levels in the project vicinity during construction to acceptable levels established by the City. HAZARDS AND HAZARDOUS MATERIALS Impact HAZ -1: Construction of the proposed project and the project variant could result in accidental releases of hazardous materials and/or the disturbance and reuse of soil potentially impacted with hazardous materials that could result in impacts to construction workers, the public, and/or the environment. Mitigation HAZ-1: A Response Plan shall be prepared by a qualified environmental professional to protect construction workers, the public, and the environment from hazardous materials, including potential unknown contamination in the subsurface of the project site. The Response Plan shall be submitted to and approved by the Regional Water Board prior to the start of construction activities, and shall include, but not be limited to, the following: 1. Procedures for evaluating, handling, storing, testing and disposing of soil and groundwater generated during project excavation and grading activities. Materials 7.A. - Page 51
