03/27/2007 and noise levels generated by construction are prohibited on Saturdays, Sundays, and holidays. (Redwood City Municipal Code Section 24.30) • Construction Equipment Mufflers and Maintenance. Equip all internal combustion engine-driven equipment with intake and exhaust mufflers that are in good condition and appropriate for the equipment. • Equipment Locations. Locate stationary noise-generating equipment as far as possible from sensitive receptors when sensitive receptors adjoin or are near a construction project site. • Construction Traffic. Route all construction traffic to and from the construction sites via designated truck routes where possible. Prohibit construction-related heavy truck traffic in residential areas where feasible. • Quiet Equipment Selection. Use quiet construction equipment, particularly air compressors, wherever possible. • Temporary Barriers. Construct solid plywood fences around construction sites adjacent to residences, operational businesses, or noise-sensitive land uses. • Temporary Noise Blankets. Temporary noise control blanket barriers should be erected, if necessary, along building facades of construction sites. This mitigation would only be necessary if conflicts occurred which were irresolvable by proper scheduling. (Noise control blanket barriers can be rented and quickly erected.) • Noise Disturbance Coordinator. For larger construction projects, the City may choose to require project designation of a "Noise Disturbance Coordinator" 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, etc.) and institute reasonable measures to correct the problem. Conspicuously post a telephone number for the Disturbance Coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule. (The project sponsor should be responsible for designating a Noise Disturbance Coordinator, posting the phone number, and providing construction schedule notices. The Noise Disturbance Coordinator would work directly with an assigned City staff member.) Finding: Implementation of these measures would reduce this intermittent, short-term, project construction-period noise impact to a less-than- significantlevel. Impact 11-2: Precise Plan-Facilitated Ground-Borne Vibration Levels. Precise Plan implementation related individual project demolition and construction activities could generate substantial vibration (e.g., from potential pile driving) in the project vicinity. These possible intermittent and short-term effects represent a potentially significant impact (see criterion 2 and explanatory text in subsection 11.3.1, "Significance Criteria," above). Mitigation 11-2. Reduce ground-borne vibration levels during individual, site specific future project demolition and construction periods by incorporating Atty/Reso/Reso.1683 26 14769 030707 Muff #613
