The Project would <br /> result in a less than significant impact in this regard. <br /> Operational Onsite Stationary Noise <br /> Upon full buildout, the main stationary operational noise associated with the Proposed Project would be <br /> parking lot activity (i.e. internal vehicle circulation, car doors opening and closing, people talking, stereo <br /> music), sirens from emergency vehicles, and helicopter landing and takeoff.As previously stated, Section <br /> 9-1025.9 of the San Joaquin County Municipal Code exempts from noise standards any mechanical <br /> device, apparatus or equipment used, related to, or connected with, emergency activities or emergency <br /> work.As such, the noise produced from emergency vehicles (sirens) and emergency response helicopter <br /> activity are exempt in the County. Nonetheless, a full discussion of the predicted sound levels generated <br /> by emergency vehicles has been included for full disclosure purposes. The onsite operational noise as a <br /> result of the Proposed Project is discussed in terms of non-exempt and exempt noise. <br /> Noise 4.15-25 October 2021 <br />
