LAX Noise Management

FAA's Southern California Metroplex Project

Los Angeles World Airports (LAWA) is committed to being a good neighbor; we strive to minimize aircraft noise within surrounding communities and keep stakeholders informed of any changes in operations. As a result, we are providing information on the Federal Aviation Administration's (FAA's) Southern California Metroplex (SoCal Metroplex) project, which will modify some flight patterns to/from the Los Angeles International Airport (LAX). LAWA is not a sponsor of this project and has not been involved with developing the proposed changes to flight procedures.

Project Description

According to the FAA, the SoCal Metroplex project is intended to improve the efficiency of the airspace in Southern California by optimizing aircraft arrival and departure procedures at a number of airports, including Los Angeles International Airport (LAX), Burbank Bob Hope Airport (BUR), Long Beach Airport (LGB), Ontario International Airport (ONT), John Wayne Airport (SNA), Santa Monica Municipal Airport (SMO), Van Nuys Airport (VNY), Palm Springs International Airport (PSP), Santa Barbara Municipal Airport (SBA), and San Diego International Airport (SAN). The project may involve changes in aircraft flight paths and/or altitudes in certain areas.

Environmental Review Process

The FAA has prepared a Draft Environmental Assessment (Draft EA) to consider the potential environmental impacts of their project. This Draft EA was released on June 10, 2015, and is available on the FAA's SoCal Metroplex EA Website for public review. The FAA has to provide a minimum of 30 days for the public to review and comment on the Draft EA, and the FAA is required to respond to all comments in the Final EA document.

In June 2015, the FAA held several public workshops in locations throughout Southern California to provide information on the project and answer questions. Public Workshop meeting materials are also available on the FAA's SoCal Metroplex EA Website.

The initial review period was 30 days, however after receiving a number of requests for extension, the FAA extended the public comment period by 60 calendar days until September 8, 2015. The FAA continued to post supplemental information on the Metroplex website through August 31, 2015. The FAA subsequently extended the comment period once again by an additional 30 days to October 8, 2015. The FAA encouraged interested parties to review the SoCal Metroplex Project Draft EA, and provide written comments during the public comment period.

UPDATE: As of September 2, 2016, the FAA released the Final EA for the SoCal Metroplex Project. The determination made in the Final EA indicated that the project would not have any significant impacts under the National Environmental Policy Act. The Final EA as well as the Finding of No Significant Impact and Record of Decision have been made available to the public in addition to all final EA documents at the FAA’s SoCal Metroplex EA Website.

The FAA will be moving forward with implementing the new flight procedures starting in November 2016 and continuing through April 2017. Before publishing the procedures, the agency will conduct additional public outreach to further inform people about the changes. Specific information for additional public outreach will be announced on the FAA’s NextGen Community Engagement webpage for the SoCal Metroplex project as the information becomes available.
