EXHIBIT A <br />Resolution No. _____ Page 16 of 71 <br />Certification of the Magnolia at the Park EIR <br /> <br />• Ventilation: Residential exterior vents shall be oriented away from I-5 and N. Main Street. If such <br />an orientation cannot be avoided, then an acoustical baffle shall be placed in the attic space behind <br />the vents. <br /> <br />With the implementation of the mitigation measure identified above (MM-NOI-1), the Project’s potential <br />impacts relating to noise levels would be less than significant. (DEIR, pp. 4.8-10 through 4.8-13.) <br /> <br />8.4.2 Groundborne Vibrations <br /> <br />Threshold: Would the Project result in exposure of persons to or generation of excessive <br />groundborne vibration or groundborne noise levels? <br /> <br />Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-16 through 4.8-17.) <br />Facts in Support of Findings: Construction activities for of the Project would generate short-term <br />vibration levels that would exceed the distinctly perceptible vibration standard at receiver locations within <br />50 feet of large bulldozers usage. Therefore, Mitigation Measure NOI-2 is included to prohibit the use of <br />large mobile equipment (greater than 80,000 pounds) and loaded trucks within 50 feet of the residences <br />to the east of the Project site. With implementation of this measure, vibration impacts at the nearby <br />sensitive receptors would be less than significant. <br /> <br />Mitigation Measure NOI-2: The Project plans and specifications shall include the following. <br />requirements: <br />• Large loaded trucks and mobile equipment, such as bulldozers (greater than or equal to 80,000 <br />pounds) shall not be used within 50 feet of the eastern boundary of the Project site. Instead, smaller, <br />rubber-tired mobile equipment (less than 80,000 pounds) or equivalent alternative equipment shall <br />be used within this area during Project construction. <br />• All construction equipment, fixed or mobile, shall be equipped with properly operating and <br />maintained mufflers, consistent with manufacturers’ standards. The construction contractor shall <br />place all stationary construction equipment so that emitted noise is directed away from the noise <br />sensitive receptors nearest the Project site. <br />• The construction contractor shall locate equipment staging in areas that will create the greatest <br />distance between construction-related noise sources and noise-sensitive receivers nearest the <br />Project site during all construction. <br /> <br />With the implementation of the mitigation measure identified above (MM-NOI-2), the Project’s potential <br />impacts relating to groundborne vibration and noise levels would be less than significant. (DEIR, pp. 4.8- <br />16 through 4.8-17.) <br /> <br />8.4.3 Temporary Increase in Ambient Noise <br /> <br />Threshold: Would the Project result in a substantial temporary or periodic increase in ambient <br />noise levels in the Project vicinity above levels existing without the Project? <br /> <br />Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-22 through 4.8-24.) <br />The City hereby makes Finding 2 that “changes or alterations have been required in, or incorporated into, <br />2-52
