Mariposa County has no adopted numeric noise ordinance. The General Plan Noise Element controls noise at its source and requires an acoustical analysis for any non-residential use likely to disturb nearby homes, schools, or hospitals, using 55 dBA CNEL as the land-use compatibility benchmark.
Mariposa County has never adopted a countywide noise ordinance with decibel limits — the General Plan Noise Element (Chapter 15) states only that a noise ordinance should be considered to define the standards for the county. Noise is instead handled case by case. Policy 15.1a requires controlling noise at its source, and Implementation Measure 15-2b(1) requires an acoustical analysis whenever a non-residential use is likely to produce excessive noise at nearby noise-sensitive uses such as homes, schools, and hospitals. The Element uses 55 dBA CNEL as the compatibility threshold for those uses. A data center's chillers, cooling fans, and generator testing would be studied and conditioned through this CEQA and permit review; there is no fixed nighttime decibel cap.
There is no noise-ordinance fine schedule, since the county has no numeric noise code. A data center that exceeds the noise conditions of its permit faces enforcement — added mitigation, notices of violation, and ultimately permit revocation for continued noncompliance.
