Noise Impact Zones

The noise impact zones for ONT affect lands within the Cities of Chino, Fontana, Montclair, and Ontario and unincorporated areas of San Bernardino County. The noise compatibility policies and criteria of apply only to the affected jurisdictions and special entities (e.g., school districts) in San Bernardino County.

The noise impact zones prepared for the ONT ALUCP were taken from the master planning efforts conducted by Los Angeles World Airports (LAWA) in the mid 2000s. The noise contours represent the “No Project” scenario and reflects the existing runway configuration and a 2030 forecast of 343,000 annual operations.  Aircraft activity data upon which the contours are based are summarized in Chapter 1 of the ONT ALUCP. The City of Ontario, is the agency responsible for the ONT ALUCP, will periodically review the projected CNEL contours and, in conjunction with OIAA and ONT-IAC, update them as necessary to ensure that they continue to have a future time horizon of at least 20 years.
