The San Diego International Airport is conveniently located to many San Diego residents and businesses. Even though the location is convenient it does create some inherent challenges for those who live and work near the Airport.
SAN along with the airlines, the FAA and Air Traffic Control (ATC) strive to balance the needs of the community with those of the passengers of SAN. Even though we do not dictate the flight path (that’s the responsibility of the FAA and ATC) or fly the planes (that’s the airlines), it is our job to act as an intermediary between all parties fostering transparency in airport operations over the communities surrounding the airport.
The following pages are meant to help explain Airport Noise Mitigation's role in these tasks and what we are doing to help reduce noise in the community.
“The Curfew” is a part of the Airport Use Regulations, formally adopted as SDCRAA Code 9.40, Airport Use Regulations. In the simplest of terms, “The Curfew” is the Time of Day Restrictions that limits nighttime aircraft departures.
The following text has been excerpted from the Airport Use Regulations. If you have any questions or concerns regarding these regulations, please contact Airport Noise Mitigation at (619) 400-2789, Monday through Friday 8:00 a.m. - 5:00 p.m. During all other times, please call (619) 400-2799.
Additionally, a multiplier may be added to reflect the multiple number of violations during the previous compliance period. After the 3rd (or more) offense, the operating privileges of any operator may be terminated, or limited, on such terms and conditions, and for such period of time, as the Authority Board determines is appropriate.

What is a noise contour map and how is it produced?
A noise contour map is a map depicting the noise levels around SAN. Noise Mitigation produces noise contour maps using the CNEL metric. The noise contours are produced through the use of the FAA’s computer model called the Integrated Noise Model (INM). Airport Noise Mitigation generates four quarterly noise contour maps identifying the 65 dB CNEL contour (State and Federally defined noise impact area). In addition, a calendar year multi-contour (60 to 80 CNEL) is produced. Airport Noise then uses its GIS to produce the map and run the NIA calculations. Note: as of this date the FAA is the in the process of replacing INM with the Aviation Environmental Design Tool (AEDT), it is estimated that they will adopt this new modeling program by May of 2014.
Below are sample copies of an Annual contour map and a Quarterly contour map.
FAR Part 150
14 Code of Federal Regulations (CFR) Part 150, Airport Noise Compatibility Planning, was issued by the Federal Aviation Administration (FAA) as a final rule in January 1985. 14 CFR Part 150 sets forth the methodology and procedures to be followed when preparing aircraft noise exposure maps and developing airport /airport environs land use compatibility programs.
14 CFR Part 150 studies typically consist of two primary components: (1) the Noise Exposure Map (NEM) report which contains detailed information regarding existing and 5-year future airport/aircraft noise exposure patterns, and (2) the Noise Compatibility Program (NCP) report which includes descriptions and an evaluation of noise abatement and noise mitigation options/programs applicable to an airport.
The Quarterly Noise Report details the noise activities at the San Diego International Airport. Information includes statistical summaries, aircraft noise measurements, information on airport operations, noise complaint statistics, enforcement actions, reports on the residential sound insulation program and information about the Airport Noise Advisory Committee.
A variance is required by the California Department of Transportation when there are areas surrounding the San Diego International Airport that are impacted by more than 65 dBs of noise. Therefore, in order to maintain operations the San Diego International Airport must have conditions in place in order to reduce noise impacts to those in areas above 65 dBs of noise.
