New Significant Effect? New Significant Off-site, Cumulative Impact? New Information, More Severe Adverse Impact? 4.13 Noise Would the project: a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Significant impact No No No No b) Generation of excessive groundborne vibration or groundborne noise levels? Less than significant impact No No No No c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No impact No No No No a) Noise Levels in Excess of Adopted Standards Would the project result in: Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? The 1998 HVSP FEIR evaluated project impacts in relation to noise and found that the project would have a potentially significant impact on noise without mitigation. A list of mitigation measures from the 1998 HVSP FEIR that are applicable to the proposed project are included in the Appendix A. Of the noise mitigation measures, MM C1, MM C2, and MM C3 are not applicable to the proposed project. However, MM C4 would apply to the project. MM C4 restricts construction activities to the hours of 8:00 a.m. and 5:00 p.m. Monday through Saturday, and on Sundays and holidays from 10:00 a.m. to 6:00 p.m. This mitigation is more stringent than the City of Pleasanton Municipal Code Section 9.04.100, which allows construction between the hours of 8:00 a.m. and 8:00 p.m. daily, except Sunday and holidays when construction should be limited to the hours of 10:00 a.m. and 6:00 p.m. The more stringent mitigation applied to the HVSP will also apply to the Spotorno Ranch Project. In addition, this mitigation measure, applied to the HVSP in relation to noise, will be carried forward as a Condition of Approval for the Spotorno Ranch Project.
