guidelines for exterior noise levels as presented in Table 2. The guidelines establish desirable maximum and maximum acceptable outdoor Ifving area noise standard for different land uses.

The Code presents permissible noise intrusion levels and sets an exterior residential standard of SS dBA between the hours of 7:00 a.m, and 10:00 p.m. and 50 dBA between the hours of 10:00 p.m. and 7:OD a.m. The standards are only applicable to stationary- source noise under City control and intended to protect sensitive land uses from the effecks of nuisance noise emanating on adjoining land uses. The standards aze not used in the siting of sensitive uses that aze subject to CEQA and the standards included in Table Z. The stationary noise standards are not to be exceeded for a cumulative period of 30 minutes in any hour However, greater noise levels are permissible for shorter durations. The standazds are not to be exceeded by 5 dBA for a cumulative period of 15 minutes in airy hour, by 10 d$A for a cumulative period of 5 minutes in any hour, by 15 dBA for a cumulative period of 1 minute in any hour, or by 20 dBA for any period of time. In the event that the ambient noise already exceeds these standards, the allowable noise shall be increased to reflect the ambient noise accordingly. Again, these standards only apply to noise sources under City control and do not apply to noise that is preempted by odrer State or federal standazds. (Such preempted noise includes traffic noise for vehicles operated in accordance with the California Vehicle Code, Section 27200). The City also sets interior uoise standards for residential land uses. Section 18-313, "Interior Noise Standards" sets allowable interior noise levels of 55 dBA between the hours of 7:00 a.m. and 10:00 p.m. and 45 dBA between the hours of 10:00 p.m, and ?:00 a.m. Again, these standards are intended to protect receptors from stationary-source noise subject to City control. These stnadazds are not to be exceeded for a cumulative period of more than 5 minutes in any hour, or the standard plus 5 dBA for a cumulative period of 1 minute in any hour. The Municipal Code recognizes that some forms of noise are required for urban development and maintenance and aze difficuh to wntrol. Section 18-314, "Special provisions," provides for these exemptions. Those applicable to the project include: Section 18-314(e) which exempts noise sources associated with constnrction, repair, remodeling, or grading of any real property, provided said activities do not take place between the hours of 8:00 p.m. and 7:00 a.m. on weekdays, including Saturday, or any time on Sunday or a federal holiday, and Section 18-314 (j) that exempts any activity to the extern regulation thereof has been preempted by state or federal law. Note that in accordance with this latter section, noise generated by vehicles passing through the project area is preempted from the local standards. Additionally, the City has no published standards for vibration intrusion. 4 75D-124
