City of Pleasanton—Merritt Property Project <br />15183 Consistency Checklist Consistency Checklist <br /> <br /> <br /> 147 <br />a) Substantial Noise Increase in Excess of Standards <br />Would the project: a) Expose persons to or generation of noise levels in excess of <br />standards established in the local general plan or noise <br />ordinance, or applicable standards of other agencies? <br />Summary of Housing Element Update FEIR <br />Construction <br />The Housing Element Update FEIR indicated that a significant impact would <br />occur if project-related, noise producing construction activities exceed the <br />City’s established noise performance standards for construction activities. <br />According to Section 9.04.100 of the Municipal Code, construction noise is <br />exempt from the noise performance standards of the Noise Ordinance <br />between the hours of 8:00 a.m. and 8:00 p.m. daily, except Sunday and <br />holidays, when the exemption shall apply between 10:00 a.m. and 6:00 p.m., <br />provided the construction activity meets at least one of the following noise <br />limitations: <br />A. No individual piece of equipment shall produce a noise level <br />exceeding 83 A-weighted decibel (dBA) at a distance of 25 feet. If the <br />device is housed within a structure on the property, the measurement <br />shall be made outside the structure at a distance as close to 25 feet <br />from the equipment as possible; or <br />B. The noise level at any point outside of the property plane of the <br />project shall not exceed 86 dBA. <br /> <br />For future development projects, two types of short-term noise impacts would <br />occur during site preparation and project construction. The first type would <br />result from the increase in traffic flow on local streets, associated with the <br />transport of workers, equipment, and materials to and from the project site. <br />Based on existing traffic volumes on roadway segments adjacent to each <br />potential site for housing, any future individual development project’s <br />construction trips would not be expected to double the hourly or daily traffic <br />volumes along roadway segments in the vicinity of a development site. For <br />this reason, short-term intermittent noise from construction trips would not be <br />expected to result in a perceptible increase in hourly or daily average traffic <br />noise levels. Therefore, the Housing Element Update FEIR concluded short- <br />term construction-related noise impacts associated with the transportation of <br />workers and equipment to a development site would be less than significant.
