12/16/2019 construction activities and equipment, notifying and coordinating with nearby residences, and designating a disturbance coordinator to address noise complaints. In addition, the project does not propose the use of high-intensity construction equipment, such as pile drivers. Theproject, with the implementation ofmitigation measureMMNOI-1.2, would reduce noise impactsfrom mechanical equipment at nearby sensitive receptors by requiring the equipment type, design, and/or location be as such to meet ambient noise conditions at nearby residences. For this reason, the project's mechanical equipment would not result in a signtficant impact. The facts in support of this finding are further described on pages 118 through 119 of the Draft EIR. MM N0I-1.1 The project shall develop a construction noise control plan, which shall include, but is not limited to, the following measures: • If residents surrounding the project site complain about weekend and/or holiday construction noise or if work is disruptive to the adjacent Red Morton Community Park activities occurring on Saturdays, all weekend and holiday construction work shall cease at the City's discretion, as specified in the allowable construction hours stated in the City's Municipal Code. • Construct temporary noise barriers shall be installed, where feasible to screen stationary noise -generating equipment when located within 200 feet of adjoining sensitive land uses. Temporary noise barrier fences would provide a five dBA noise reduction if the noise barrier interrupts the line -of -sight between the noise source and receptor and if the barrier is constructed in a manner that eliminates any cracks or gaps. • If stationary noise -generating equipment is located near receptors, adequate muffling (with enclosures where feasible and appropriate) shall be used. Any enclosure openings or venting shall face away from sensitive receptors. • Construction staging areas (including material stockpiles, maintenance/equipment staging, and parking areas) shall be established at locations that would create the greatest distance between the construction -related noise sources and noise -sensitive residential receptors nearest the project site during all project construction. • Generators, compressors, and pumps shall be housed in acoustical enclosures. • Where feasible, temporary power service from local utility companies should be used instead of portable generators. • Locate cranes as far from adjoining noise -sensitive residential receptors as possible. • During final grading, substitute graders for bulldozers. Wheeled heavy equipment are quieter than track equipment. • Substitute nail guns for manual hammering. • Avoid the use of circular saws, miter/chop saws, and radial arm saws near the adjoining noise -sensitive residential receptors. Shield saws with a solid screen with material having a minimum surface density of two pounds per square feet (e.g., such as '%-inch plywood). • Substitute electrically -powered tools for noisier pneumatic tools. • Maintain smooth vehicle pathways for trucks and equipment accessing the site, and avoid local residential neighborhoods as much as possible. • During interior construction, the exterior windows facing noise -sensitive receptors shall be closed. • During interior construction, noise -generating equipment shall be located within the building to break the line - of -sight to the adjoining receptors.
