Mitigation Measure 4.4-5: Exposure of Sensitive Receptors to or Generation of Excessive Groundborne Vibration or <br /> Noise Levels.To reduce the exposure of vibration-sensitive receptors to project-generated construction source <br /> vibration levels,the City will implement the following measure: <br /> ► Construction activities within 60 feet of occupied residences will be performed without equipment that <br /> produces relatively high levels of vibration(e.g.,use jackhammers in place of hoe rams). <br /> Implementation of Mitigation Measure 4.4-5 would reduce significant impacts related to the exposure of sensitive <br /> receptors to excessive groundborne vibration to a less-than-significant level because vibration levels would not <br /> exceed FTA's maximum-acceptable standard with respect to human response for residential uses (i.e., <br /> annoyance). <br /> 4.4.4 LEVEL OF SIGNIFICANCE AFTER MITIGATION <br /> With implementation of Mitigation Measures 4.4-1 and 4.4-5,the project's potential noise and vibration impacts <br /> would be reduced to a less-than-significant level because noise and vibration levels would be reduced and <br /> construction activities would be limited to the hours during which noise levels are exempt from the provisions of <br /> the applicable construction noise standards. <br /> EDAW Manteca WQCF and Collection System Master Plans EIR <br /> Noise 4.4-22 City of Manteca <br />
