Southern California Metroplex Project

Metroplex Lawsuit Update

As of February 8, 2018:

On January 19, 2018, the Federal Aviation Administration (FAA), the Department of Transportation (DOT) and the U.S. Department of Justice (DOJ) approved the Settlement Agreement with the City of Newport Beach and the County of Orange. For more information, please see the January 29, 2018 County press release and executed copy of the Settlement Agreement.


In 2003, Congress directed the development of a ”Next Generation Air Transportation System.“ NextGen, as it is now called, was intended to improve aviation safety and efficiency through the use of ground-based and, increasingly, space-based technology. An important part of the NextGen initiative is the development of new airspace and air traffic procedures.

The Federal Aviation Administration’s (FAA) approach to the mandate from Congress was to divide the United States into 21 “metroplexes.” John Wayne Airport (JWA), along with Burbank, Long Beach, Ontario, Los Angeles and a number of other airports comprise the “Southern California Metroplex.”

The Southern California Metroplex Project is the FAA’s proposal to improve the efficiency and safety of air traffic into and out of the Southern California area. A key feature of the Southern California Metroplex Project is to create more repeatable and predictable flight paths, both vertically and laterally.

The County’s concern regarding the inadequacy of the FAA’s environmental review led the Board of Supervisors to file a lawsuit challenging FAA’s “Finding of No Significant Impact” and “Record of Decision.” The Cities of Laguna Beach and Newport Beach filed lawsuits on similar grounds. The Washington, D.C. Court of Appeals granted the County’s petition to intervene in the City of Newport Beach’s lawsuit.
