Bellflower caps industrial noise at 45 decibels beyond the site boundary at all hours under Municipal Code Section 17.52.170. That single all-day limit is far tighter than the 70 dBA Los Angeles County allows on unincorporated industrial land.
Section 17.52.170(A) bars any M-1 use from creating a sound level beyond the site boundaries above 45 decibels, measured on the A-weighted curve of American Standard Z 24.3. Bellflower sets one number for every hour of the day, with no daytime allowance and no separate residential table. Cooling towers, chillers, and generator testing at a data center run continuously, so the 45 dBA property-line cap governs around the clock. Section 17.52.170 also bars vibration, heat, glare, and electrical disturbance beyond the site. Chapter 8.32 adds a nuisance layer: noise audible beyond 200 feet of the property line in or within 500 feet of a residential zone violates the code.
Exceeding 45 dBA at the M-1 site boundary violates Title 17 and is enforced by Bellflower Code Enforcement through notices, citations, and abatement, with Chapter 8.32 nuisance charges available separately.
