The City of Hawthorne has prepared a voluntary Noise Exposure Map update in accordance with Title 14 of the Code of Federal Regulations, Part 150 (14 CFR Part 150) for Hawthorne Municipal Airport.  The study was a cooperative effort between the City and the Federal Aviation Administration (FAA).  This Noise Exposure Map update, which was funded through Airport funds and by a grant from the FAA, was designed to update noise exposure maps originally published in 2013 in conjunction with a 14 CFR Part 150 Study initiated in 2011 for the airport.  It is important to understand what this study did and did not do:

A Noise Exposure Map Update:

  • Identifies the current and projected annualized aircraft noise levels at Hawthorne Municipal Airport using the Community Equivalent Noise Level (CNEL) noise metric.
  • Identifies impacts on noise-sensitive land uses in the airport environs.


A Noise Exposure Map Update does not:

  • Evaluate strategies to reduce the noise impacts above 65 CNEL from aircraft operating to and from Hawthorne Municipal Airport.
  • Encourage future land uses which are compatible with aircraft noise, such as commercial or industrial in undeveloped areas.
  • Determine methods to reduce the adverse impacts of noise above 65 CNEL.
  • Establishes procedures to implement, review, and update the program.
  • Evaluate aircraft operations from other area airports.
  • Consider other types of impacts (air quality, accidents, etc.).
  • Use noise metrics other than CNEL to determine noise impacts.
  • Provide justification for airport expansion.
