The Certified EIR also conchided that long-term noise impacts for <br />the Approved Project would be less than "significant. Therefore, the Revised Project would not <br />result in new 'significant impaets:beyond those identified in the Certified EIR. No new mitigation <br />measures are required. <br />d) As discussed in Response 2.1 La, above, implementation of the Revised Project would include <br />construction activities that would result in a substantial temporary increase in ambient noise <br />levels in the Project site vicinity above levels existing without the Project, but would no longer <br />occur once construction is completed. The Revised Project would be required to comply- with <br />Mitigation pleasure NOI-I "from the Certified EIR, which requires compliance with the'City's <br />noise ordiaiance,;ntitlling of construction equipment, coordination with neighbors to resolve <br />noise complaints, and construction of a temporary noise barrier around the'Projectsite. <br />Implementation of Mitigation Measure-NOI-1 would reduce noise impacts during construction of <br />the Revised Project to a less than significant level. The Certified EIR also concluded'that <br />implementation of Iviftigation.Measure N01-1 would reduce noise impacts during construction of <br />the Approved project to a less than significant level.'fherefore, the Revised Project would not <br />result in new significant impacts beyond those identified in the Certified EIR. No new initigation <br />measures are required. <br />e) The Project siteis approximately 2 miles northeast of John Wayne Airport (SNA) and is within <br />the Land Use Planning Arca for this;airport.a Thu Project site is approximately 13 milCs,outsidc' <br />.of the 66 dBA noise contours of this airport'; therefore, the noise -related impact due to airport <br />activities would be less than siemiftcant and no mitigation is required, -The CertifiedEiR also <br />Found that the Project site is not located within the airport contours. Therefore,, the Revised <br />Project would not rusult in new signifearrt impacts beyond those identified in the Certified EiR. <br />No new mitigation measures are required.. <br />Mitigation Measures: <br />Based on the analysis and information above, Mitigation Measure NO -1 included in the Certified EIR <br />for the Approved'Project would be applicable to the Revised Project. <br />NO -1 'llie project contractor(s) shall implement, but not be limited to, the following best <br />management practices <br />• Outdoor construction work mi the project shall be limited to the hours of <br />7:00 a.m. to 8:00 p,m. on weekdays and Saturdays. No construction activities <br />shall occur.on Sundays.or federal holidays <br />• All construction equipment with a high noise generating potential, including all <br />equipment powered by internal combustion engines, shall be muffled or <br />controlled <br />I Airport Land Usc Commissions,.
