3.0 ENVIRONMENTAL CHECKLIST <br />1388 Bancroft Avenue Project City of San Leandro <br />Initial Study/Mitigated Negative Declaration November 2018 <br />3.0-58 <br />4-1-1115 Prohibited Acts <br />(b) Construction-related Noise Near Residential Uses. Construction work or related activity which is adjacent to or across a street or right of way from a residential use, except <br />between the hours of 7 a.m. and 7 p.m. on weekdays, or between 8 a.m. and 7 p.m. on <br />Sunday and Saturday. No such construction is permitted on Federal holidays. As used in this Article, “construction” shall mean any site preparation, assembly, erection, substantial repair, alteration, demolition or similar action, for or on any private property, public or <br />private right-of-way, streets, structures, utilities, facilities, or other similar property. <br />Construction activities carried on in violation of this Article may be enforced as provided in Section 4-11-1130, and may also be enforced by issuance of a stop work order and/or <br />revocation of any or all permits issued for such construction activity. <br />4-1670 Performance Standards <br />B. Vibration. No use, activity, or process shall produce vibrations that are perceptible without instruments by a reasonable person at the property lines of a site. <br />City of San Leandro General Plan <br />The City’s General Plan Environmental Hazards Element identifies sources of noise in the city and <br />defines standards for acceptable noise levels and policies to reduce the impacts of noise to the community. Chart 7-2 from the General Plan lists noise compatibility guidelines for land uses based <br />on the State of California guidelines; for multi-family residential land uses, a CNEL of up to 65 dBA <br />would be normally acceptable. The following goal and policies from the Environmental Hazards <br />Element are relevant to the proposed project (San Leandro 2016a): <br />Goal EH-7 Ensure that noise associated with the day-to-day activities of San Leandro <br />residents and businesses does not impede the peace and quiet of the <br />community. <br />Policy EH-7.1 Noise Compatibility Table. Ensure that potential noise impacts are considered when new development is proposed. Projects that could <br />significantly increase noise levels should incorporate mitigation measures to <br />reduce such impacts. Apply the standards shown in Chart 7-2 when evaluating applications for future development. Chart 7-2 specifies the maximum noise levels that are normally acceptable, conditionally <br />acceptable, and normally unacceptable for new development. <br />Policy EH-7.2 Residential Interior Noise Standard. As required by the State of California, ensure that interior noise levels in new residential construction do not <br />exceed 45 dB Ldn. For non-residential construction, the acceptable interior <br />noise levels should be determined on a case by case basis, depending on <br />the type of activity proposed. <br />Policy EH-7.3 Residential Exterior Noise Standard. Strive to maintain an exterior noise level of no more than 60 dB Ldn in residential areas. Recognizing that some San <br />Leandro neighborhoods already exceed this noise level, encourage a <br />variety of noise abatement measures that benefit these areas.
