Aircraft noise around Portland International Airport (PDX) is governed by federal law (FAA) rather than Portland City Code. The Port of Portland operates a voluntary FAA Part 150 Noise Compatibility Program, runs a 24/7 noise complaint system, and publishes annual noise contour maps. The City of Portland cannot regulate aircraft in flight or restrict airport operations.
Under the federal Airline Deregulation Act and the Airport Noise and Capacity Act of 1990 (49 U.S.C. 47521-47534), the FAA preempts local regulation of aircraft noise in flight, takeoff, and landing. The Port of Portland, which owns and operates PDX, administers an FAA-approved Part 150 Noise Compatibility Study and publishes 65 dB DNL (Day-Night Average Sound Level) contour maps that determine eligible homes for sound insulation grants. The Port runs a 24/7 noise hotline and an online complaint portal at flypdx.com; complaints are forwarded to the FAA, airlines, and PDX Air Traffic Control for tracking but do not generate fines. The Port has voluntary noise abatement procedures — preferred runways (10R/28L for nighttime arrivals to limit overflights of NE/SE Portland), preferential departure headings over the Columbia River, and Fly Quiet awards for compliant carriers. Single-event noise from low-altitude flights, helicopter operations from the Pearl District heliport, and general aviation from Hillsboro Airport (HIO) and Troutdale Airport (TTD) are tracked separately. Homes inside the 65 DNL contour in East Portland may qualify for Port-funded acoustical insulation. Portland City Code Title 18 (Noise Control) explicitly exempts aircraft operations.
Because federal law preempts local enforcement, there are no City of Portland fines for aircraft noise. Complaints filed with the Port of Portland are routed to the FAA and the operator; persistent violations of FAA-published noise abatement procedures may result in FAA action against a pilot or airline certificate. Residents who believe their home qualifies for Port sound-insulation programs should contact the Port's Noise Office directly.
