o Table 2-1 (continued) 3 � Summary of Impacts and Mitigation Measures (Applicable to Program and Project-Specific Impacts) W z Impact Significance Mitigation Measure Significance before Mitigation after Mitigation 4.13.4.Noise—Compatibility of Proposed Land Uses S Mitigation Measure 4.13-4: Noise—Compatibility of Proposed LTS Exceeding Predicted Noise Levels.The proposed project would Land Uses exceeding Predicted Noise Levels.The College Park result in the development of noise-sensitive land uses(residential)in developers shall implement the following measures: an area where predicted noise levels would exceed land use . Traffic Noise—Arterials.Before occupancy of the first compatibility noise standards established by the San Joaquin County residence proposed under the College Park project along each General Plan 2010 and MHMP.A significant impact would occur. of the seven arterial segments identified in Table 4.13-11,a sound barrier snail be constructed by the College Park developers along that arterial segment.The noise barrier may consist of a wall,berm,or combination thereof.The exact location,height and character of the sound barrier shall be determined by a noise consultant approved by the County.The sound barrier shall reduce outdoor noise levels at the center of backyards of proposed adjacent single-family residences to below 65 dBA LadCNEL and as close to 60 dBA LddCNEL as feasible.This mitigation shall be funded through fair-share N payments by the College Park developers. o ► Traffic Noise—I-205.The County shall conduct annual acoustical monitoring at the southernmost sites of the proposed residential,community park,community college buildings/common area,and limited industrial uses.The monitoring shall include 24-hour measurements at the affected properties.At such time as the monitoring indicates that freeway noise levels at the above residential,community park,community college,and limited industrial sites are greater than the applicable K noise thresholds(65 dBA CNEL for residential and park uses,70 g dBA CNEL for college uses,and 75 dBA CNEL for limited EDindustrial uses),a noise barrier shall be constructed along the north side of 1-205 by the College Park developers to protect the g affected receptor(s).The required location,height,and character of the noise barrier shall be determined by a noise consultant Cn hired by the County.This mitigation shall be funded through fair- share payments by the College Park developers. Sound barriers could be constructed to protect the proposed d land uses from future freeway noise levels. For instance,a sound wall 12 feet high located approximately 50 feet from the O edge of 1-205 would reduce freeway noise exposure at the 0 to south property line of the proposed Delta College site to 69.8 En
