Designate a noise disturbance coordinator <br /> who wouid be responsible for responding to any local complaints about <br /> construction noise. The dis#urbance coordinator would determine the cause <br /> of the noise complaint(e.g., starting too early, bad muftler, etc.} and institute <br /> reasanable measures warranted to correct the problem. Conspicuously post <br /> a telephone number for the disturbance coordinator at the construction site. <br /> (The Ciiy should be responsible for designating a noise disturbance <br /> coordinator and the project applicant should be responsible for posting the <br /> phone number and providing construction schedule notices). <br /> 3. Construction Hours. Restrict noise-generating construction activity to <br /> bstween the hours of 7:00 AM and 7:00 PM, Monday through Friday. Prohibit <br /> such construction activities �n weekends and holidays. <br /> 4. Construcfron Barrrer. Construct a perimeter, soiid plywood constructian <br /> barrier, eight feet high, to shieid nearby residentia! land uses fram <br /> canstruction noise. Prohibit site access on common boundaries between the <br /> project site and adjacent residential land uses (e.g., the Villas at Bair island} <br /> during construction phases. <br /> 5. Construcfion Equipmenf Mufflers and Mainfenance. Properly muffle and <br /> mainiain all construction equipm�nt powered by internal combustion engines. <br /> 6. Equipment Location. Locate a!I stationary noise-generating construction <br /> equipment, such as air compressors, as far as practica! from nearby <br /> residences. <br /> 7. Truck Routes. Route all canstruction traffic to and from the project site via <br /> designated truck routes where practical. Prohibit constru�tian-refated heavy <br /> truck traffic in residentiai areas where feasibfe. <br /> 8. Quiet Equipment Selection. Utilize quiet construction equipment, particular[y <br /> air compressors, whenever possible. <br /> 9. Pile Driving. Utilize multiple pile drivers to expedite this phase of project <br /> construction and reduce the duration of associated impacts. <br /> 10. Blanket Barriers. Caver piie drivers with temporary noise-contral b{anket <br /> barriers. <br /> 11. Pile Holes. Pre-drilf foundation pile holes to minimize the number of <br /> percussions required to seat the pile. <br /> Findings: Because these measures woufd reduce this impact fo the greates# <br /> extant feasibfe, and because the impact woufd ae in#ermittent and short-term, the mitigation <br /> would reduce the impact to a less-fhan-significant level. <br /> Atty/Reso/Reso.1772 40 <br /> 121307 <br />
