City of Santa Ana <br />MainPlace Mall Transformation <br />Traffic Noise <br />Addendum to the <br />Fashion Square Commercial Center Final EIR <br />The proposed Project would result in additional traffic on adjacent roadways, thereby <br />increasing vehicular noise near existing and proposed land uses. As shown in Table N- <br />6, roadway noise levels would range from 61.3 to 68.7 dBA. The highest increase in <br />noise levels would occur along Bedford Road, which would increase by 2.1 dBA. This <br />level is below the perceptible noise level change of 3.0 dBA. Thus, impacts would be <br />less than significant. No new impact would occur. <br />In addition, as detailed in Section 5.6, Traffic and Circulation, the traffic generated by <br />the proposed Project would be less than what would occur under the current <br />entitlements for the site. Table N-7 compares the Existing Plus Project noise condition <br />to the Currently Entitled noise condition and shows that the proposed Project would <br />result in lower traffic noise levels on all roadway study segments compared to what <br />would occur under the Current Entitlements. <br />Table N-7: Existing Plus Project Traffic Noise Levels <br />Existing <br />With Current <br />Project <br />Project <br />Conditions <br />Entitlements <br />With Project <br />Change <br />Change <br />from <br />from <br />Roadway <br />dBA <br />dBA <br />dBA <br />Existing <br />Existing <br />Significant <br />Segment <br />ADT <br />CNEL <br />ADT <br />CNEL <br />ADT <br />CNEL <br />Conditions <br />Entitlement <br />Impact? <br />Main Street <br />Chapman Ave to <br />29,664 <br />66.9 <br />35,042 <br />67.7 <br />35,332 <br />67.7 <br />0.8 <br />-0.7 <br />No <br />La Veta Ave <br />La Veta Ave to <br />Main Place Dr/ <br />35,291 <br />67.8 <br />42,668 <br />68.6 <br />42,651 <br />68.6 <br />0.8 <br />-0.8 <br />No <br />Town and <br />Country Rd <br />Main Place <br />Dr/Town and <br />Country Rd to <br />29,094 <br />67.0 <br />36,905 <br />68.0 <br />35,903 <br />67.9 <br />0.9 <br />-1.0 <br />No <br />East City Place <br />Dr/Mall Entrance <br />Memory Lane to <br />30,433 <br />67.2 <br />38,919 <br />68.2 <br />37,710 <br />68.1 <br />0.9 <br />-1.1 <br />No <br />Santa Clara Ave <br />Santa Clara Ave <br />to West 171h St <br />31,257 <br />67.0 <br />36,237 <br />67.6 <br />35,709 <br />67.6 <br />0.6 <br />-0.6 <br />No <br />Bedford Road <br />La Veta Ave to 7 323 59.3 12,017 61.4 11,901 61.4 2.1 2.2 No <br />Main Place Dr <br />N.
