Mitigation Monitoring and Reporting Program L. Noise <br />Page 86 <br />NOISE <br />Mitigation Measure: L5. Require a combination of soundwall and construction tech- <br />uiques, such as sound rated windows and walls, in residential <br />units near the railway that are (or would be, with future rail <br />service) exposed [o exterior maximum train passby noise levels <br />of 75 dBA or more. <br />Impact to be Mitigated: Outdoor noise levels slung railroad tracks would exceed the threshold at <br /> which controls are required [o reduce interior noise levels. <br />AgeocyQndividual <br />Responsible for Developers of residential projects exposed to noise levels of 75 dIIA or <br />Implementation: more from the UPRR tracks. <br />Implementation Timing: During construction of residential units. <br />Mitigation Specifications: The August, 2000 Specific Plan calls for soundwalls eight feet high along <br /> the rairoad tracks where train operations would otherwise result in unac- <br /> ceptablenoise conditions. The walls would corner inward toward the center <br /> of [he parcels along roadways to provide for more complete buffering where <br /> necessary. <br /> Where housing would be located nett to [he tracks, building orientation, <br /> building elements, and/or architectural walls that would further reduce noise <br /> levels in outdoor use areas are specified in the plan. <br />AgeocyHndividual <br />Responsible for <br />Monitoring: City of Pleasanton, Planning Department and Building Department <br />Action by Monitor: (1) Verify that soundwalls specified in the August, 2000 Specific Plan <br /> are included in the final development plans. <br /> (2) Review plans for residential units to assure [hat mitigation for <br /> excessive outdoor noise is included, as appropriate and feasible. <br /> (3) Verify [ha[ soundwalls are built as specified. <br /> (4) Verify that noise mitigation fcalures required for individual units <br /> are built as specified. <br />Monitoring Timing: (1) Prior to approval of final development plans <br /> (2) Prior to issuance of building permits for rosidential units <br /> (3) Prior to acceptance of public improvements <br /> (4) Prior to acceptance of public improvements <br />Monitor: Completion Date: Signature: <br />
