Industrial and utility uses in unincorporated Polk County must keep noise from being excessive at the lot line, and heavy-industrial and extractive/disposal uses require conditional-use permits with noise-abatement plans. Home occupations must produce no noise detectable at the property line.
The Polk County Zoning Ordinance controls industrial noise through lot-line performance standards: public and utility uses must not produce noise excessive at the lot lines, and the Zoning Administrator can require licensed-engineer certification. Heavy industrial, extractive (mining), and disposal uses need conditional-use permits and must submit machinery noise levels and noise-abatement methods for review. Home occupations are held to a stricter test: no noise detectable at the property line. Firearm ranges must submit actual noise levels and abatement procedures.
Zoning violations are misdemeanors abatable under Chapter 2 of the Polk County Code; conditional-use permit noise conditions are enforced as permit conditions, and nuisance actions can assess civil penalties.
