The Coast Guard is establishing a permanent security zone extending 40 yards into the navigable waters of the main channel of Los Angeles Harbor, including the perimeter of the Coast Guard Base on Terminal Island in San Pedro, CA. This is necessary for the security of military service members on board vessels moored at the pier, and military members and government property. All persons and vessels will be prohibited from entering, transiting through, or anchoring within a portion of Los Angeles Harbor’s Main Channel surrounding Terminal Island, unless authorized by the Captain of the Port Los Angeles–Long Beach.
