Summary
Livermore sets data-center noise through two codes. Industrial performance standards cap ambient noise at 75 dB(A) beyond the site boundary and 60 dB(A) at a residential (R) district boundary under LPZC 2-61-080. The general noise ordinance separately bars fan and blower noise plainly audible 75 feet away.
Noise. No use shall be permitted which creates an ambient noise level greater than 75 decibels (dba) beyond the boundaries of the site, nor greater than 60 decibels (dba) at the boundary of an R district.
Full Breakdown
Livermore regulates data-center noise in two places. The I-2 and I-3 industrial performance standards (LPZC 2-61-080(B)(2) and 2-64-080(B)(2)) prohibit any use that creates ambient noise above 75 dB(A) beyond the site boundary, or above 60 dB(A) at the boundary of an R (residential) district, with no day-night split. Separately, Municipal Code Chapter 9.36 bars loud, unnecessary noise as a nuisance: Section 9.36.040 prohibits blower, power-fan, and combustion-engine noise unless muffled so it is not plainly audible 75 feet from the source. Industrial areas more than 500 feet from a residential development are exempt from the ordinance's nighttime hour limits.
Violations & Fines
Noise above the 75 or 60 dB(A) performance limits, or fan and generator noise plainly audible 75 feet away, is a code violation the City abates through citations and permit conditions.
