Ontario International Airport – Inter Agency Collaborative

The Ontario International Airport – Inter Agency Collaborative (ONT-IAC) was formed to insure that new development is compatible with the Ontario International Airport (ONT) Influence Area (AIA). The ONT-IAC implements the policies and criteria of the Airport Land Use Compatibility Plan (ALUCP) to prevent future incompatible land uses surrounding ONT and minimizing the public’s exposure to excessivie noise and safety hazards. The ALUCP does not address existing incompatible land uses and does not place any restrictions on the airport or its flight operations.

ONT-IAC is represented by all agencies affected by existing and future airport impacts and administered by the City of Ontario. It’s members include representatives from the County of San Bernardino and the cities of Chino, Fontana, Montclair, Ontario, Rancho Cucamonga, and Upland.

This inter-agency partnership works to protect the public, health, safety and welfare and fulfill state requirements to protect the airport from encroachment of incompatible lans uses and protect the areas around the airport from environmental impacts.

Compatibility Factors

Airspace Protection Zones

The airspace protection zones for Ontario International Airport primarily affect lands within the Cities of Ontario, Rancho Cucamonga, and Upland.  The Cities of Chino, Fontana, and Montclair and unincorporated areas of San Bernardino County are affected to a lesser extent.  Portions of the airspace protection zones also extend into the Counties of Riverside and Los Angeles however Airspace protection policies are only advisory.


FAA Notification Process

The Federal Aviation Administration (FAA) conducts aeronautical studies to determine the impact of a proposed structure, an existing structure that has not yet been studied by the FAA, or an alteration of an existing structure on aeronautical operations, procedures, and the safety of flight. The FAA will issue a determination stating whether the proposed construction or alteration would be a hazard to air navigation, and will advise all known interested persons.

When to Notify the FAA

The requirements for filing with the FAA for proposed structures vary based on a number of factors: height, proximity to an airport, location, and frequencies emitted from the structure, etc. For more details, please reference Code of Federal Regulations (CFR) Title 14 Part 77.9. FAA requires you to file at least 45 days prior to construction if:

  • Your structure will exceed 200ft above ground level;
  • Your structure will be in proximity to an airport and will exceed the slope ratio;
  • Your structure involves construction of a traverseway (i.e. highway, railroad, waterway etc…) and once adjusted upward with the appropriate vertical distance would exceed a standard of 77.9(a) or (b) your structure will emit frequencies, and does not meet the conditions of the FAA Co-location Policy;
  • Your structure will be in an instrument approach area and might exceed part 77 Subpart C;
  • Your proposed structure will be in proximity to a navigation facility and may impact the assurance of navigation signal reception your structure will be on an airport or heliport; or
  • Filing has been requested by the FAA

FAA has created a Notice Criteria tool to assist sponsors with determining if a project should be filed with the link provided FAA Notice Criteria Tool Link

How to Notify the FAA

If you are required to notify the FAA, then you must electronically file a 7460-1 Form for the Construction or Alteration, for structures located OFF or ON airport property, the link is provided https://oeaaa.faa.gov/oeaaa/external/portal.jsp

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.

Noise Management

Airport noise concerns are managed by the Ontario International Airport Authority (OIAA). The OIAA provides overall direction for the management, operations, development and marketing of Ontario International Airport (ONT). To register a comment regarding airport noise, you may call (909) 937-2719, 24 hours a day. Please provide the time the aircraft flew over, the direction the aircraft was headed, and if possible, the type of aircraft and airline (or color scheme). OIAA also has the option of filing noise complaints through their flight tracking website, below are links to OIAA noise management and flight tracking website (ONT WebTrack).

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.

Safety Zones

The five safety zones are based upon the existing airfield configuration, the methodology utilized is provided in Chapter 1 of the ONT ALUCP. The ONT ALUCP Safety Zones are located solely within Ontario’s city limits. The intent of the Safety Zones and associated policies is to minimize the risks associated with an off-airport aircraft accident or emergency landing. The policies focus on the following objectives:

  • Protect people and property on the ground;
  • Minimize injury to aircraft occupants; and
  • Prevent the creation of hazards to flight.

Safety Zone policies establish the maximum number of people per acre allowed within each safety zone. The policies are implemented by limiting and prohibiting certain land uses, limiting a buildings floor are ratio (FAR) and limiting the storage of hazardous material.

Compatibility Plan

The Ontario International Airport Land Use Compatibility Plan (ONT ALUCP) was adopted by Ontario City Council on April 19, 2011. The basic function of the ONT ALUCP is to promote compatibility between ONT and the land uses that surround it. As required by State law, the ALUCP provides guidance to affected local jurisdictions with regard to airport land use compatibility matters involving ONT. The main objective of the ALUCP is to avoid future compatibility conflicts rather than to remedy existing incompatibilities. Also, the ALUCP is aimed at addressing future land uses and development, not airport activity. The ALUCP does not place any restrictions on the present and future role, configuration, or use of the airport.

The geographic scope fo the ONT ALUCP is the Airport Influence Area (AIA), the area in which current or future airport-related noise, safety, airspace protection and/or overflight factors may affect land uses or impose restrictions on those uses. The AIA includes portions of the cities of Chino, Claremont, Fontana, Montclair, Ontario, Pomona, Rancho Cucamonga and Upland, the counties of Los Angeles, Riverside and San Bernardino.

The ONT ALUCP is organized into two chapters and a set of appendices. Chapter 1 identifies the background data and methodology utilized for the basis of the ALUCP and Chapter 2 identifies airport and land use information, compatibility policies and criteria, compatibility zone maps and procedural policies.
