4.6 – Noise Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.6-7 City of Tracy City of Tracy General Plan The City of Tracy General Plan Noise Element includes as Objective N-1.2, Control Sources of Excessive Noise, Policy P4, the requirement in new development projects that all construction in the vicinity of noise-sensitive land uses (including residences) be limited to daylight hours or 7 a.m. to 7 p.m. Additionally, the following construction noise control measures are required (City of Tracy 2011): • Equip all internal combustion engine-driven equipment with intake and exhaust mufflers that are in good condition and are appropriate for the equipment. • Locate stationary noise-generating equipment as far as possible from sensitive receptors when sensitive receptors adjoin or are in the vicinity. • Utilize “quiet” air compressors and other stationary noise sources where such technology exists. City of Tracy Municipal Code Section 4.12.750, General Sound Level Limits, of the City of Tracy Municipal Code specifies 1-hour average sound level limits by land use: • Residential Districts: 55 dBA Leq 1-hour • Commercial Districts: 65 dBA Leq 1-hour • Industrial Districts: 75 dBA Leq 1-hour • Agricultural: 75 dBA Leq 1-hour • AMO Aggregate Mineral: 75 dBA Leq 1-hour 4.6.3 Thresholds of Significance The significance criteria used to evaluate a project’s impacts related to noise are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines. According to Appendix G of the CEQA Guidelines, a significant impact related to noise would occur if a project would: A. 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. B. Result in generation of excessive groundborne vibration or groundborne noise levels. 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, expose people residing or working in the project area to excessive noise levels. D. Result in cumulatively considerable noise impacts. Threshold C was analyzed in the Initial Study (Appendix A) and was not carried forward for further analysis in this Environmental Impact Report. See Chapter 5, Effects Found Not To Be Significant, for additional detail.
