Welcome to the Southern California Metroplex (SoCal METROPLEX) Environmental Assessment Website

The FAA has prepared a Draft Environmental Assessment (EA) in accordance with FAA Order 1050.1E to document the potential environmental effects associated with the optimization of aircraft routes and the supporting airspace management structure serving aircraft operating under instrument flight rules (IFR) while departing from or arriving to the Southern California Metroplex area.

Please use the navigation bar on the left to access important information on the Draft EA, including details on the public participation process for the Draft EA and contact information for the Project.

Google EarthThe FAA has prepared files depicting the SoCal Metroplex project alternatives and noise analysis results in Google Earth format.  The files can be found here.

The Draft EA for the SoCal Metroplex project was released and made available for public review and comment beginning on Wednesday, June 10, 2015. The public comment period ended on Thursday, October 8, 2015. The public comment period is now closed.

Eleven public workshops were held throughout the SoCal Metroplex General Study Area between June 16 and July 1, 2015. During the workshops, representatives from the FAA and its Consultant Team were available to answer questions about the project. Materials presented to the public during the public workshops are available here for download and review.

The Project

The SoCal Project would improve the efficiency of airspace in the Southern California Metroplex by optimizing aircraft arrival and departure procedures at Bob Hope (Burbank) Airport (BUR), Camarillo Airport (CMA), Mc Clellan-Palomar Airport (Carlsbad) (CRQ), Fullerton Municipal Airport (FUL), Los Angeles International Airport (LAX), Long Beach Airport (Daugherty Field) (LGB), Camp Pendleton MCAS (Munn Field) Airport (NFG), Point Mugu Naval Air Station (NTD), North Island Naval Air Station (NZY), Ontario International Airport (ONT), Oxnard Airport (OXR), Palm Springs International Airport (PSP), San Diego International Airport (SAN), Santa Barbara Municipal Airport (SBA), Brown Field Municipal Airport (SDM), Santa Monica Municipal Airport (SMO), John Wayne-Orange County Airport (SNA), Jacqueline Cochran Regional Airport (TRM), Bermuda Dunes (UDD), Miramar Marine Corps Air Station (NKX) and Van Nuys Airport (VNY).  The Project may involve changes in aircraft flight paths and altitudes in certain areas, but would not result in any ground disturbance or increase the number of aircraft operations within the Southern California airspace.
