Ramboll - Stoneridge Mall Residential Project <br />158850326.2 <br />9/11 <br />Confidential <br />Figure 2. Nearby Non-Transportation Noise Sources <br />CadnaA was used to predict sound levels at the Project site boundaries and the building façade. For 6200 <br />and 6210 Stoneridge Mall Road, the rooftop mechanical screens were assumed to be visual screens, not <br />acoustical barriers. The results of the analysis are summarized in Table 6. As shown in Table 6, the limit <br />of 60 dBA is not exceeded at any of the locations. <br />Table 6.
