No person shall produce or allow to be produced by any machine, animal, device, or any combination of the same, on commercial property, a noise level in excess of 70 dBA at any point outside of the property plane, unless otherwise provided in this chapter. (Ord. 2055 § 2, 2012; Ord. 1880, 2003; prior code § 4-9.04) Construction Noise (Section 9.04.100) • Between the hours of 8:00 a.m. and 8:00 p.m. daily, except Sunday and holidays, when the exemption shall apply between 10:00 a.m. and 6:00 p.m., construction, alteration or repair activities which are authorized by a valid city permit shall be allowed if they meet at least one of the following noise limitations: A. No individual piece of equipment shall produce a noise level exceeding 83 dBA at a distance of 25 feet. If the device is housed within a structure on the property, the measurement shall be made outside the structure at a distance as close to 25 feet from the equipment as possible; or B. The noise level at any point outside of the property plane of the project shall not exceed 86 dBA. Would the project result in: 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? Construction Source Noise Impacts Less than significant impact with mitigation incorporated. For purposes of this analysis, a significant impact would occur if construction activities would result in a substantial temporary increase in ambient noise levels outside of the City’s permissible hours for construction that would result in annoyance or sleep disturbance of nearby sensitive receptors, or if construction noise levels exceed 86 dBA as measured at any point outside of the property plane of the project. While the City does not define the noise metric for this standard, for purposes of this analysis the noise metric is assumed to be an hourly average Leq. Construction-related Traffic Noise Noise impacts from construction activities associated with the proposed project would be a function of the noise generated by construction equipment, equipment location, sensitivity of nearby land uses, and the timing and duration of the construction activities. One type of short-term noise impacts that could occur during project construction would result from the increase in traffic flow on local streets, associated with the transport of workers, equipment, and materials to and from the project site. The transport of workers and construction equipment and materials to the project site would incrementally increase noise levels on access roads leading to the site. Because workers and construction equipment would use existing routes, noise from passing trucks would be similar to
