Navigation



The Los Angeles District of the U.S. Army Corps of Engineers is responsible for 14 harbors along the Southern California coast stretching from San Diego Harbor near the Mexican border to Morro Bay Harbor on California's central coast.  Some of our projects include: The ports of Los Angeles and Long Beach which together makeup the fifth busiest port complex in the world and account for more than $420 billion in cargo annually, San Diego Harbor which is home to Naval Base Point Loma and the U.S. Third Fleet, Naval Air Station North Island, Naval Amphibious  Base Coronado and the Port of San Diego which is a key regional commerce hub and in Los Angeles County,  Marina del Rey Harbor which was constructed by the Army Corps of Engineers in 1965 and is one of the largest recreational harbors in the United States with 5,300 slips.

The Navigation mission is to provide safe, reliable, efficient, effective, and environmentally sustainable waterborne transportation systems (i.e. channels, harbors, and waterways) for movement of commerce, national security needs and recreation. Responsibilities include planning and constructing new navigation channels, ports, and harbors, and maintaining channel depths along coastal channels, ports, and harbors.

The navigation program is vital to the nation’s economy. Our nation’s coastal transportation system encompasses a network of navigable channels, ports, harbors, and infrastructure maintained by the Corps, as well as publicly and privately owned vessels, terminals, inter-modal connections, shipyards, and repair facilities. Coastal navigation is a key element of State and local government economic development and job-creation efforts, and is essential in maintaining economic competitiveness and national security.
