Unincorporated Glenn County does not set its own aircraft-noise limits. Glenn County Code Section 15.56.100 expressly exempts 'aircraft when subject to federal or state regulations' from the county's noise standards. Aircraft noise is governed by the FAA and California Department of Transportation, Division of Aeronautics, not by the county code.
Glenn County's noise authority stops at aircraft. The zoning noise performance standard, Section 15.56.100 of the Glenn County Code (Ordinance 1183, 2006), lists among its exemptions 'aircraft when subject to federal or state regulations.' Because federal law preempts most aircraft and airspace noise control, the county does not, and generally cannot, impose its own in-flight or overflight decibel limits. Aircraft noise is regulated primarily by the Federal Aviation Administration (FAA) under federal aviation law, with airport-related land-use compatibility handled at the state level through the California Department of Transportation (Caltrans) Division of Aeronautics and through Airport Land Use Commission planning (Public Utilities Code sections 21670 and following). Willows-Glenn County Airport and Orland-Haigh Field operate within that federal/state framework. The 2023 amplified-sound ordinance, Chapter 10.25, addresses audio equipment only and has no bearing on aircraft. Residents concerned about aircraft noise should direct complaints to the airport operator, the FAA, or the relevant Airport Land Use Commission rather than to county code enforcement. These notes describe unincorporated Glenn County; municipal airports within Willows or Orland fall under their respective jurisdictions and the same federal preemption.
The county does not cite aircraft noise; it is expressly exempt under Section 15.56.100. Aircraft noise complaints are handled by the FAA, the airport operator, and the Caltrans Division of Aeronautics under federal and state aviation law.
