Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential noise impacts: Mitigation Measure 4.5-4: 1Noise Effects of Gravel Harvesting Operations Specific Plan measure 4.5-3 (above) shall be implemented to also minimize noise levels on the project site from offsite gravel harvesting operations. Additional mitigation of the above impact is the responsibility and jurisdiction of Alameda County, consistent with the mining and reclamation permit issued to RMC Lonestar in 1981 and the Livermore Amador Valley Quarry Reclamation Specific Plan. Mitigation to reduce adverse impacts is available in the Livermore Amador Valley Quarry Reclamation Specific Plan to Alameda County, and can and should be adopted by the County. Specific economic, legal, social, technological, or other considerations make infeasible the alternatives identified in the environmental impact report that would definitively reduce this impact to a less-than-significant level. SIGNIFICANT EFFECT Impact 4.5-5: Traffic Noise Effects. Noise-sensitive land uses located along the proposed Vineyard Avenue re-alignment could be exposed to traffic noise levels in excess of the City' s exterior noise standards. Consequently, traffic noise would be considered a potentially significant impact to these noise-sensitive receptors. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential noise impacts to a less-than-significant level: Mitigation Measure 4.5-5: Traffic Noise Effects A minimum six-foot high landscaped earth berm shall be constructed along the Vineyard Avenue frontage of Lots 4, 8, 9, 10, 11, and 13, and a decorative masonry soundwall and landscaping shall be constructed along the Vineyard Avenue frontage of Lot 1 and be designed to complement the existing soundwall and landscaping on the north side of Vineyard Avenue. , All new two-story homes constructed less than 140 feet from the centerline of the re- aligned of Vineyard Avenue shall have a fresh air ventilation and/or air conditioning system to allow residents to maintain closed windows for noise control. · Potential bed and breakfast facilities shall be designed to ensure that interior noise levels of the occupied rooms are less than 45 dBA L~. Sound rated windows shall be required for all rooms with a view of Vineyard Avenue. Because windows must remain closed to obtain the required noise reduction, mechanical ventilation (e.g., air conditioning) shall be provided for all rooms. A Title 24 analysis shall be required during the design phase to define the noise control recommendations and specify noise control measures to be incorporated into the building design. · The existing speed limit on Vineyard Avenue between Bernal Avenue and Montevino Drive shall be reduced from 40 mph to 35 mph in order to reduce traffic noise levels.
