Full Breakdown
Escondido's Noise Abatement and Control ordinance, Municipal Code Sec. 17-229, makes it unlawful for the one-hour average sound level to exceed the table limit at or beyond the source property's boundary. Limits by receiving zone: residential 50 dB (7 a.m.-10 p.m.) and 45 dB (10 p.m.-7 a.m.); multi-residential 55/50; commercial 60/55; light industrial and industrial park 70 dB anytime; general industrial 75 dB anytime. Where two dissimilar uses meet, the more restrictive limit applies. A data center's continuous cooling towers, chillers, and backup generators are measured against the nearest receiver - the 45 dB overnight residential limit binds where an industrial site abuts homes.
Violations & Fines
Noise over the Sec. 17-229 limits is unlawful and enforced by Escondido Code Compliance through citations; for a discretionary-permitted data center it can breach the noise conditions imposed on its Conditional Use Permit.
