Chapter 2 Results of the Noise Study Report ........................................ .................. ............ Of the 92 modeled receptors, 9 receptors under the Future Build condition would approach or exceed the NAC. No receptor would experience a substantial noise increase of 12 dBA or more over its corresponding modeled existing noise level under any scenario. The receptor locations listed below would be or would continue to be exposed to noise levels that either approach or exceed the NAC under Future Build conditions: • Receptor R-5: This receptor location represents an existing single-family residence on the northbound side of Fairview Street between Civic Center Drive and West 9th Street. Currently, a 4.7 ft high existing wall (Existing Wall [EW] No. 1) shields the residence. One noise barrier (NB No. 1) was modeled along the private property line on the northbound side of Fairview Street to shield this residence. • Receptor R-8: This receptor location represents an existing single-family residence on the southbound side of Fairview Street between Civic Center Drive and West 9th Street. Currently, a 2.7 ft to 6 ft high existing wall (EW No. 2) shields this residence. One noise barrier (NB No. 2) was modeled along the private property line on the southbound side of Fairview Street to shield this residence. • Receptor R-14: This receptor location represents an existing single-family residence on the southbound side of Fairview Street between West 9th Street and West 12th Street. Currently, a 5.3 ft high existing wall (EW No. 4) shields this residence. One noise barrier (NB No. 3) was modeled along the private property line on the southbound side of Fairview Street to shield this residence. • Receptor R-23: This receptor location represents existing multifamily residences on the southbound side of Fairview Street between West 9th Street and West 12th Street. Existing wood fences along the private property line would not provide effective noise attenuation at these residences. One noise barrier (NB No. 4) was modeled along the private property line on the southbound side of Fairview Street to shield these residences. • Receptors R-24, R-25, and R-40: These receptor locations represent existing single-family residences on the northbound side of Fairview Street between West 9th Street and West 12th Street. Currently, a 4 ft to 6 ft high wall (EW No. 5) shields these residences. One noise barrier (NB No. 5) was modeled along the private property line on the northbound side of Fairview Street to shield these residences.
