Section 9-1022.5 Noise Attenuation Walls <br /> Walls, fences,berms,and/or landscaping for the purpose of noise attenuation may be required in any zone when <br /> adjacent to a high noise generator such as a major roadway or railroad.Noise attenuation requirements shall be <br /> developed in response to the noise level and source affecting a specific property. Where noise attenuation walls <br /> are required,height and yard restrictions for walls shall be waived by the Director as required for effective noise <br /> reduction. <br /> Section 9-1025.5 Vibration <br /> (a) Perceptible Displacement.No use shall cause perceptible displacement at any lot line abutting any zone <br /> except an I-G Zone. <br /> (b) Displacement within the General Industrial Zone.Vibration displacement along any lot line within an I-G <br /> Zone shall not exceed the levels set forth in Table 9-1025.5 (see Table 4.4-4). Vibration displacement shall be <br /> measured by a seismograph or other instrument capable of measuring and recording displacement and <br /> frequency,particle velocity, or acceleration. Readings shall be made at points of maximum vibration along <br /> any lot line with an I-G Zone. <br /> Table 4.4-4 <br /> San Joaquin County Development Code Table 9-1025.5: Maximum Displacement Levels at Any Lot Line <br /> Frequency(Cycles per Second) Steady State(inches) Impact(inches) <br /> 10 and below 0.0010 0.0020 <br /> 10-20 0.0008 0.0016 <br /> 20-30 0.0007 0.0014 <br /> 30-40 0.0003 0.0006 <br /> 40-50 0.0002 0.0004 <br /> 50-60 0.0001 0.0002 <br /> 60 and over 0.0001 0.0002 <br /> Source:San Joaquin County Development Code,Title 9,issued in 1999 and updated in 2002 <br /> Section 9-1025.9 Noise <br /> All uses and property shall be subject to the following provisions concerning noise levels: <br /> (b) Stationary Noise Sources. <br /> (1) Excluding proposed noise sensitive land uses on infill lots,proposed noise sensitive land uses that <br /> will be impacted by stationary noise sources shall be required to mitigate the noise levels from these <br /> stationary noise sources so that the resulting noise levels on said proposed noise sensitive land uses <br /> do not exceed the standards specified in Table 9-1025.9,Part II(Table 4.4-5). <br /> (2) Proposed projects that will create new stationary noise sources or expand existing stationary noise <br /> sources shall be required to mitigate the noise levels from these stationary noise sources so as not to <br /> exceed the noise level standards specified in Table 9-1025.9,Part II(Table 4.4-5). <br /> (c) Exemptions.The following shall be exempt from the provisions of this Chapter: <br /> EDAW Manteca WQCF and Collection System Master Plans EIR <br /> Noise 4.4-10 City of Manteca <br />
