Palmdale FAQ
Does my Palmdale property require an aircraft noise disclosure?
Yes, if your property lies within the Accident Potential Zone (APZ) or Air Installations Compatible Use Zones (AICUZ) overlay, the city requires a disclosure statement at sale that the property is subject to frequent overflight and aircraft noise from Plant 42.
Why are there restrictions on building homes near Plant 42?
The city restricts noise-sensitive land uses within the 65 dBA CNEL contour and Frequent Overflight Area to protect the operational viability of USAF Plant 42 and to protect residents from sustained high-noise impacts.
South San Gabriel FAQ
Can my city ban loud planes overhead?
No. Federal law preempts municipal regulation of aircraft in flight. California's state rules govern airport-side noise contours, but cities cannot impose flight path or altitude restrictions.
Who do I complain to about aircraft noise?
Contact the airport proprietor's noise office first, then Caltrans Division of Aeronautics for state-level concerns and the FAA for in-flight or air traffic control issues.
