(d) The land use designation of the affected receptor sites; <br /> (e) Public reactions or controversy as demonstrated at workshops or hearings, or by correspondence; <br /> (f) Prior CEQA determinations by other agencies specific to the project <br /> Implementation Measure N-I-4: Control noise at the source through use of insulation,berms,building <br /> design and orientation,buffer space, staggered operating hours and other techniques. Use noise barriers to <br /> attenuate noise to acceptable levels. <br /> City of Manteca Municipal Code <br /> The purpose of Chapter 17.13 of the City of Manteca Municipal Code,Performance Standards, is to provide <br /> necessary control measures to protect the community from hazards and nuisances and to establish limits and <br /> procedures for measuring the nuisances. The general statement of the section is, "Land or buildings shall not be <br /> used or occupied in a manner creating any dangerous injurious,noxious, fire, explosive or other hazard; noise, <br /> vibration, smoke, dust, order or form of air pollution; heat, cold, dampness, electrical or other disturbance; glare, <br /> refuse or wastes; other substances, conditions or elements which would adversely affect the surrounding area" <br /> (City of Manteca 1992). <br /> With respect to noise, Section 17.13.040A specifies maximum allowable sound pressure levels for various land <br /> uses.Normal household appliances and construction equipment operated between the hours of 7 a.m. to 7 p.m. are <br /> exempt from these standards. The maximum sound pressure levels radiated by any use or facility shall not exceed <br /> the computed noise level values specified in Table 4.4-8, after applying corrections. This regulation is commonly <br /> referred to as the noise ordinance. <br /> Table 4.4-8 <br /> City of Manteca Municipal Code Noise Performance Standards <br /> Receiving Land Use Category Time Period Maximum Exterior Noise Level (dBA) <br /> Single and Limited Multiple Family 10 p.m.-7 a.m. 50 <br /> 7 a.m.-10 p.m. 60 <br /> Multifamily residential,Public Institutional and 10 p.m.—7 a.m. 55 <br /> Neighborhood Commercial 7 a.m.-10 p.m. 60 <br /> Medium and Heavy Commercial <br /> 10 p.m.—7 a.m. 60 <br /> 7 a.m.-10 p.m. 65 <br /> Light industrial Anytime 70 <br /> Heavy industrial Anytime 75 <br /> Notes:dBA=A-weighted decibels.The following corrections are applicable(apply only one correction): <br /> Daytime Operation Only(7 a.m.—7 p.m.):+5 decibels <br /> Noise Source Operates Less Than: <br /> 20%of any 1-hour period:+5 decibels <br /> 5%of any 1-hour period:+10 decibels <br /> 1%of any 1-hour period:+15 decibels <br /> Noise of Impulsive Character(hammering,etc.):-5 decibels <br /> Noise Rising or Falling in Pitch or Volume(hum,screech,etc.):-5 decibels <br /> Source:City of Manteca 1992 <br /> Section 17.13.04013 specifies vibration requirements.No vibration shall be produced that is transmitted through <br /> the ground and is discernible without the aid of instruments,nor shall any vibration produced exceed 0.002g(in <br /> acceleration attributable to gravity)peak at up to 50 cycles per second(cps) frequency,using either seismic or <br /> electronic vibration-measuring equipment. Vibrations occurring at higher than 50 cps frequency of a periodic <br /> vibration shall not induce accelerations exceeding 0.001g. Single impulse periodic vibrations occurring at an <br /> average interval greater than 5 minutes shall not induce accelerations exceeding 0.01g. <br /> Manteca WQCF and Collection System Master Plans EIR EDAW <br /> City of Manteca 4.4-15 Noise <br />
