TABLE 1-1 SUMMARY OF IMPACTS AND MITIGATION MEASURES <br />Significant Impact <br />Significance <br />Before <br />Mitigation <br />LTS = Less Than Significant S = Significant SU = Significant Unavoidable Impact <br />SAN LEANDRO SHORELINE DEVELOPMENT DRAFT EIR <br />CITY OF SAN LEANDRO <br />EXECUTIVE SUMMARY <br />Mitigation Measures <br />■ Prior to initiation of on-site construction -related demolition or <br />earthwork activities, a minimum 6 -foot -high temporary sound <br />barrier shall be erected along the project property line abutting <br />adjacent operational businesses, residences or other noise - <br />sensitive land uses. These temporary sound barriers shall be <br />constructed with a minimum surface weight of four pounds per <br />square foot and shall be constructed so that vertical or horizontal <br />gaps are eliminated. These temporary barriers shall remain in <br />place through the construction phase in which heavy construction <br />equipment, such as excavators, dozers, scrapers, loaders, rollers, <br />pavers, and dump trucks, are operating within 150 feet of the <br />edge of the construction site by adjacent sensitive land uses. This <br />measure could lower construction noise levels at adjacent ground <br />floor residential units by up to 8 dBA, depending on topography <br />and site conditions; <br />■ Erect temporary noise control blanket barriers, if necessary, along <br />building fagades facing construction sites to prevent sleep <br />disturbance. This mitigation would only be necessary if conflicts <br />occurred which were irresolvable by proper scheduling; <br />■ To the maximum extent feasible, route construction -related <br />traffic along major roadways and away from sensitive receptors; <br />■ Notify all businesses, residences or other noise -sensitive land <br />uses within 500 feet of the perimeter of the construction site of <br />the construction schedule in writing prior to the beginning of <br />construction and prior to each construction phase change that <br />could potentially result in a temporary increase in ambient noise <br />levels in the project vicinity; <br />■ Signs shall be posted at the construction site that include <br />permitted construction days and hours, a day and evening <br />contact number for the job site, and a day and evening contact <br />number for the on-site complaint and enforcement manager, and <br />the City's Chief Building Official, in the event of problems; <br />■ An on-site complaint and enforcement manager shall be available <br />to respond to and track comDlaints.
