Hesperia FAQ
Can Hesperia police ticket a pilot for low or noisy aircraft?
No. Aircraft in flight are regulated by the FAA. Local officers cannot enforce flight-altitude or aircraft-noise rules. File complaints with the FAA or with San Bernardino County as the L26 airport sponsor.
Are Hesperia homes inside the 65 CNEL contour?
Per the San Bernardino County Airport Land Use Compatibility Plan, Hesperia Airport's 65 CNEL contour stays within the existing airport boundary, so residential parcels along its perimeter sit below the State's 65 CNEL annoyance threshold.
Ontario FAQ
Can Ontario restrict aircraft noise at ONT?
No. Federal law preempts local restrictions on aircraft operations. The FAA and airport operator manage noise through the Part 150 program and voluntary procedures.
How do I file an aircraft noise complaint?
Use the Ontario International Airport noise complaint hotline or online portal. Complaints are logged and used to inform Part 150 updates.
