Overflight Notification Zones
Noise from individual aircraft operations, especially loud aircraft, can be intrusive and annoying in locations beyond the limits of the Noise Impact Zones. Sensitivity to aircraft overflights varies from one person to another. The purpose of overflight compatibility policies is to help notify people about the presence of overflights near airports so that they can make more informed decisions regarding acquisition or lease of property in the affected areas.
The overflight zones for ONT affect the Cities of Chino, Fontana, Montclair, Ontario, Rancho Cucamonga, and Upland and unincorporated areas of San Bernardino County. Portions of the Cities of Claremont and Pomona in Los Angeles County and the unincorporated areas of Riverside County are also within the overflight zones.
Overflight compatibility policies do not restrict the manner in which land can be developed or used. Overflight policies establish the language and recommended geographic coverage for notification about airport proximity and aircraft overflights.
