Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-16 through 4.8-17.) Facts in Support of Findings: Construction activities for of the Project would generate short-term vibration levels that would exceed the distinctly perceptible vibration standard at receiver locations within 50 feet of large bulldozers usage. Therefore, Mitigation Measure NOI-2 is included to prohibit the use of large mobile equipment (greater than 80,000 pounds) and loaded trucks within 50 feet of the residences to the east of the Project site. With implementation of this measure, vibration impacts at the nearby sensitive receptors would be less than significant. Mitigation Measure N0I-2: The Project plans and specifications shall include the following requirements: • Large loaded trucks and mobile equipment, such as bulldozers (greater than or equal to 80,000 pounds) shall not be used within 50 feet of the eastern boundary of the Project site. Instead, smaller, rubber -tired mobile equipment (less than 80,000 pounds) or equivalent alternative equipment shall be used within this area during Project construction. • All construction equipment, fixed or mobile, shall be equipped with properly operating and maintained mufflers, consistent with manufacturers' standards. The construction contractor shall place all stationary construction equipment so that emitted noise is directed away from the noise sensitive receptors nearest the Project site. • The construction contractor shall locate equipment staging in areas that will create the greatest distance between construction -related noise sources and noise -sensitive receivers nearest the Project site during all construction. With the implementation of the mitigation measure identified above (MM-NOI-2), the Project's potential impacts relating to groundborne vibration and noise levels would be less than significant. (DEIR, pp. 4.8- 16 through 4.8-17.) Consistent with the Original Project construction activities for of the Modified Project would generate short-term vibration levels that would exceed the distinctly perceptible vibration standard at receiver locations within 50 feet of large bulldozers usage. Therefore, like the Original Project, Mitigation Measure NOI-2 would be required to reduce vibration impacts to a less than significant level. No new or greater impacts related to vibration would occur from implementation of the Modified Project. (Final EIR, Clarifications to the Final EIR, Section 3.8.) 8.4.3 Temporary Increase in Ambient Noise Threshold: Would the Project result in a substantial temporary or periodic increase in ambient noise levels in the Project vicinity above levels existing without the Project? Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-22 through 4.8-24.) The City hereby makes Finding 2 that "changes or alterations have been required in, or incorporated into, the Project that mitigate or avoid the significant effects on the environment." Mitigation Measure NOI-3 has been included to minimize and/or avoid the Project's potential impacts relating to temporary increases in ambient noise levels in the Project vicinity.
