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.
Rialto FAQ
Can I report a low-flying plane to Rialto code enforcement?
No. In-flight aircraft are federally preempted. File noise complaints with the FAA Western-Pacific Region or directly with Rialto Municipal Airport management.
Does Rialto have a nighttime airport curfew?
No mandatory curfew. Any new curfew would require FAA Part 161 approval, which is rarely granted.
