Summary

Neither Jefferson County nor Colorado's noise statute regulates aircraft noise. CRS 25-12-103(4) states the article does not apply to aircraft, which are governed by federal (FAA) law. Rocky Mountain Metropolitan Airport handles local complaints.

These county ordinances apply to unincorporated areas of Jefferson County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

This article is not intended to apply to the operation of aircraft or to other activities which are subject to federal law with respect to noise control.

Full Breakdown

Colorado's noise statute expressly excludes aircraft and other activities subject to federal noise-control law, so the county's 55/50 dB(A) limits do not apply to overflights. Aircraft noise is regulated by the Federal Aviation Administration. Jefferson County is home to Rocky Mountain Metropolitan Airport (BJC), which operates a voluntary noise-abatement program and a complaint line for residents affected by general-aviation and flight-training traffic. Residents disturbed by aircraft should file with the airport's noise office rather than the Sheriff.

Violations & Fines

No county citation applies; aircraft noise is a federal matter. Local recourse is the airport's voluntary noise-abatement and complaint process.

Frequently Asked Questions

Can I report a loud plane to the Sheriff?
No. Aircraft are exempt from the noise statute and are regulated by the FAA; direct complaints to Rocky Mountain Metropolitan Airport's noise-abatement program.
Does the county set any airport noise limits?
No enforceable dB limit applies to flights. The airport uses voluntary noise-abatement procedures rather than county citations.
