City of Pleasanton—Vineyard Avenue Residential Project <br />Consistency Checklist 15183 Consistency Checklist <br /> <br />136 <br /> <br />nearest noise-sensitive receptors, which include the single-family residences <br />to the west, south, and east, would be site grading and the construction of <br />the buildings closest to that particular neighbor. During the remainder of <br />construction, activities would occur farther away from the nearby residences. <br />The Noise Assessment assumed that project construction would comply with <br />the requirements of Section 9.04.100 of the City’s Municipal Code, and that <br />construction activities would occur only during the permitted hours of 8:00 <br />a.m. and 8:00 p.mp, Monday through Saturday, and between the hours of <br />10:00 a.m. to 6:00 p.m. on Sundays and holidays. As previously discussed, the <br />City’s noise ordinance further allows construction activity unless individual <br />pieces of equipment produce a noise level exceeding 83 A-weighted <br />decibels (dBA) at 25 feet or the noise level at any point outside of the <br />property plane exceeds 86 dBA. <br />The Noise Assessment evaluates equipment typical for each stage of project <br />construction. As shown in Table 4, typical construction equipment produces <br />noise levels above 83 dBA at 25 feet. However, in order to represent the <br />average noise levels at each construction phase, Veneklasen assumed that <br />the equipment would be moving between the center of the site and near all <br />property lines. Based on the equipment listed in Table 4, construction of the <br />proposed project would result in the noise levels listed in Table 5 below. As <br />shown in the table, project construction noise levels would range between 71 <br />to 82 dBA at the nearest property line. Nonetheless, the Noise Assessment <br />included measures to further minimize construction noise at surrounding <br />sensitive receptors. <br />Table 4 <br />Sound Levels of Typical Equipment Used In Construction <br />Phase Name Equipment Type Sound Level at 50 feet <br />Phase 1 – Site Clearance <br />Chainsaw 85 <br />Tractor 88 <br />Shovel 82 <br />Phase 2 – Grading Dozer 85 <br />Grader 85 <br />Phase 3 – Site Utility <br />Delivery Truck 88 <br />Excavators 85 <br />Forklifts 80 <br />Phase 4 – Foundation and <br />Slab Pouring <br />Excavators 85 <br />Concrete Truck Mixture 85 <br />Phase 5 – Paving <br />Dozer 85 <br />Paver 88 <br />Roller 85 <br />Phase 6 – Building Pneumatic tools 85
