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.
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.
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.
