7A <br />Page 42 <br />and proposed City policies giving priority to the Downtown pedestrian <br />environment (see Section 9.1.1 of this FEIR chapter). The City Council ofi the <br />City of Redwood City chooses to avoid this mitigation option in the interest of <br />protecting the pedestrian environment. This impact is overridden by project <br />benefits as set forth in the statement of overriding considerations and in the <br />pedestrian priority objectives set froth in section 9.1.1 of this FE1R chapter. <br />V. NOISE <br />A. Noise and Vibration Impacts <br />Impact 1'f-1: Precise Plan-Facilitated Demolition and Construction <br />Period <br />Noise. Demolition and construction activities facilitated by the Downtown Precise <br />Plan could temporarily elevate noise levels at nearby residential and commercial <br />receptors during individual, site-specific project construction periods. Noise levels <br />at 50 feet from the demolition or construction equipment source could reach <br />approximately. 105 dBA, resulting in intermittent interference with typical existing <br />residential and business activities, and exceeding the land use/noise level <br />compatibility limits established in the Redwood City Strategic General Plan Noise <br />Elemenf. This possibility represents a potentially significant intermittent and <br />short-term noise impact. <br />Mitiga#ion 11-1. Reduce Precise Plan implementation related individual <br />project demolition- and construction-period noise impacts on nearby residences <br />by incorporating conditions in project demolition and construction contract <br />agreements that stipulate the following conventional construction-period noise <br />abatement measures: <br />• Cc~nstrucfion FPan. Prepare a detailed construction plan identifying the <br />schedule for major noise-generating construction activities. The construction <br />plan shall identify a procedure for coordination with nearby noise-sensitive <br />facilities so that construction activities and the event schedule can be <br />scheduled to minimize noise disturbance. <br />• Construction Scheduling. Ensure that noise-generating construction activity is <br />limited to between the hours of 7:00 AM to 8:00 PM, Monday through Friday, <br />and noise levels generated by construction are prohibited on Saturdays, <br />Sundays, and holidays. (Redwood City Municipal Code Section 24.30) <br />Construction Equipment Mufflers and Mainfenance. Equip all internal <br />combustion engine-driven equipment with intake and exhaust mufflers that <br />are in good condition and appropriate for the equipment. <br />• ~quiprnenf Locafions. Locate stationary noise-generating equipment as far as <br />possible from sensitive receptors when sensitive receptors adjoin or are near <br />a construction projec# site. <br />Atty/Reso/Reso.1683 25 <br />030707 <br />
