Aircraft Noise: Carson vs South Gate
How do aircraft noise rules compare between Carson, CA and South Gate, CA?
Carson and South Gate have similar restriction levels.
Carson, CA
Los Angeles County
Carson has no local aircraft noise ordinance. Federal law preempts local regulation of in-flight aircraft noise; the FAA has exclusive sovereignty over U.S. navigable airspace under 49 U.S.C. §40103, and City of Burbank v. Lockheed Air Terminal, 411 U.S. 624 (1973), struck down municipal aircraft curfews. The Airport Noise and Capacity Act (ANCA), 49 U.S.C. §§47521–47534, further restricts local airport noise rules and requires FAA approval through the 14 CFR Part 161 process. Carson does not own or operate an airport, so it has no 'airport proprietor' authority either. Aircraft overflight from LAX, Long Beach Airport, Compton/Woodley, Hawthorne Municipal, and helicopter traffic from the LA Basin is regulated solely by FAA Order 8260, 14 CFR Part 91 Subpart I, and Stage 3/4/5 certification rules. Carson's adopted noise ordinance (LA County Code Title 12 Ch. 12.08 by reference) expressly does not apply to aircraft in flight.

Los Angeles County
South Gate has no local aircraft noise ordinance. Aircraft in flight are preempted by federal law (FAA/Noise Control Act of 1972); ground-level airport noise standards are set by Caltrans Division of Aeronautics under Cal. Pub. Util. Code §21669 using a 65 dB CNEL threshold for incompatible residential exposure. South Gate is in the Los Angeles County urban core; while not adjacent to LAX, the city sits under jet approach corridors and helicopter routes used by LAPD/LASD, news media, and medical operators. Noise complaints about aircraft must be directed to the operating airport's noise office (LAX, Long Beach, Compton/Woodley) or the FAA Western-Pacific Region, not to South Gate Code Enforcement.

Carson FAQ
Can Carson set a curfew on overhead flights from LAX?
No. The Supreme Court in City of Burbank v. Lockheed Air Terminal (1973) held that federal law preempts local aircraft curfews. Only the FAA — and, in limited respects, the airport proprietor (LAWA for LAX) — can impose flight restrictions.
Where do I file an LAX overflight complaint?
Call the LAWA Noise Management Office at 424-646-6473 or use the online complaint form at lawa.org. For Long Beach Airport, use lgb.org/noise. Carson Code Enforcement cannot act on in-flight aircraft noise.
Does Carson regulate drone noise?
Carson has no drone-specific noise ordinance. Drone flight is regulated by the FAA under 14 CFR Part 107. Carson can enforce trespass, reckless endangerment, or privacy laws (Cal. Civ. Code §1708.8) but not flight altitude, routes, or noise.
What about helicopter noise from refinery security or news flights?
Helicopter operations are FAA-regulated under 14 CFR Part 91 and Part 135. The FAA's Los Angeles Helicopter Noise Initiative (HNI) is the voluntary program for the region. Carson has no enforcement authority over in-flight helicopters.
South Gate FAQ
Can South Gate Code Enforcement stop a noisy plane or helicopter?
No. Aircraft-in-flight noise is federally preempted under the Noise Control Act of 1972 and FAA regulations. South Gate Municipal Code does not cover aircraft. Complaints must go to the FAA or the operating airport's noise office.
Why are police helicopters allowed to hover so low at night?
FAR 91.119(d) exempts law enforcement, EMS, and operations necessary for the helicopter's intended purpose from the 1,000-foot minimum-altitude rule over congested areas. LAPD, LASD, and news helicopters are routinely lawful at low altitude.
Is South Gate inside an airport CNEL 65 contour?
No major commercial airport's 65 dB CNEL contour extends into South Gate per Caltrans noise inventories. The closest impact comes from Long Beach Airport approach paths and Compton/Woodley general aviation, neither of which produces 65+ CNEL exposure in South Gate residential areas.
