Full Breakdown
Galt's Noise Control Standards, Municipal Code § 8.40.040, make it unlawful to create noise that raises levels on an affected property above the exterior standard. In residential and mixed-use zones (R1A through R4, DR, MU, DMU) the limit is an hourly Leq of 50 dB(A) daytime (7 a.m.-10 p.m.) and 45 dB(A) nighttime (10 p.m.-7 a.m.), with maximum levels of 70 and 65 dB. Limits drop 5 dBA for pure-tone or impulsive noise. A data center's continuous chillers, cooling towers, and backup generators are measured at the nearest residential property - the 45 dB(A) night floor binds where an industrial site abuts homes.
Violations & Fines
Noise exceeding the § 8.40.040 standards at an affected property is unlawful, enforced by Galt Code Compliance through citations, and for a permitted data center, breach of the noise conditions on its use permit.
