Summary
Outdoor generators near environmentally sensitive habitat must be sited as far as practicable from ESHA receptors or screened by a structure or solid wall under the county's coastal-zone noise standards.
When sound-producing outdoor equipment is proposed on a lot that could impact a nearby ESHA noise sensitive receptor, the equipment shall be sited and designed to meet the following standards:(1)Locate sound-producing outdoor equipment (e.g., roof/ground-mounted HVAC, pumps, generators, compressors, and fans) as far as practicable from the ESHA noise sensitive receptor(s) or locate the equipment in an area where existing or proposed structures or solid walls act as a noise barrier between the noise source and ESHA noise sensitive receptor(s).(2)Cooling towers for power facilities and other industrial uses shall be sited and designed to direct noise away from ESHA noise sensitive receptor(s). When feasible, cooling towers shall be sited in such a manner that nearby structures or equipment acts as a noise transmission barrier. See Section 8178-2.6.13(c) for construction noise standards.
(Ord. No. 4586, 10-19-2021)
*Noise standards in this Section only apply to temporary film productions that require a coastal development permit. For permitting requirements, see Section 8174-5.
Full Breakdown
In the unincorporated coastal zone, sound-producing outdoor equipment such as generators, HVAC units, pumps, compressors and fans that could affect a nearby ESHA noise-sensitive receptor must be located as far as practicable from that receptor, or sited so an existing or proposed structure or solid wall blocks the noise path. The rule applies within ESHA and buffer zones and the Santa Monica Mountains overlay zone, not countywide.
Violations & Fines
Enforced as a coastal development permit condition; noncompliant siting can trigger permit denial, code enforcement action, or a stop-work order from the Planning Division.
