Farmington Hills, MI Noise Ordinances: Aircraft Noise (2026)

Federal preemption is the controlling rule. The Airport Noise and Capacity Act of 1990 (ANCA, 49 U.S.C. 47521 et seq.) bars airport operators from imposing new noise-based aircraft operational restrictions without FAA approval, and federal law preempts local governments from regulating routes, altitudes, and operating hours of aircraft in flight. Detroit Metropolitan Wayne County Airport (FAA identifier DTW / ICAO KDTW), owned and operated by the Wayne County Airport Authority (WCAA), is the dominant aircraft-noise source affecting Farmington Hills - approximately 25 miles to the southeast in Romulus, with primary runway alignments 04/22, 03L/21R, 03R/21L, 09L/27R, and 09R/27L. The WCAA Noise Compatibility Program (NCP) combines an FAA-approved Part 150 Noise Compatibility Plan with Air Traffic Control Tower (ATCT) procedures including a fanning departure procedure that disperses departure tracks to reduce concentrated noise on any single neighborhood under noise-sensitive land uses. Practical effect for Farmington Hills: westerly and northwesterly DTW departures from Runways 22 / 21L / 21R climb out over the I-275 / I-696 / I-96 / Northwestern Highway / Telegraph Road quadrant, with the Farmington Hills / West Bloomfield / Bloomfield Township ridge regularly receiving turn-out traffic. Easterly arrivals to DTW Runways 04 / 03L / 03R routed over the Oakland County corridor will descend through the 4,000 - 7,000 ft band over the city. Oakland County International Airport (PTK / KPTK) in Waterford Township is the regional general-aviation and corporate-jet airport (Runway 09R/27L / 09L/27R) and contributes propeller and light-jet noise primarily on the city's north-end pattern legs. Bishop International Airport (FNT / KFNT) in Flint is the more distant Part 121 alternative. Farmington Hills Sec. 17-101 contains no aircraft-noise provisions; aircraft-in-flight complaints are not citable by city authority. The WCAA Noise Compatibility Office at DTW operates 24 hours a day to receive public comments and complaints and to review noise exposure maps; Oakland County International publishes voluntary noise-abatement procedures through its airport administration. The federal community-wide mitigation mechanism is the FAA Part 150 noise compatibility study process. Coast Guard and military overflight, where applicable, is federally operated and similarly exempt from local enforcement.
