Ammunition Pier Replacement Project

In December 2019 construction began on a Navy project to build a replacement ammunition pier, associated waterfront facilities, causeway and public boating channel inside Anaheim Bay. The project is scheduled to take up to five years to complete. See below for project updates, timelines, and additional information.

Anaheim Bay Navigation Changes

A new civilian boating channel through the Anaheim Bay opened to the public in January 2021.  With the new channel opened, the old channel has become part of the Naval Weapons Station Seal Beach restricted area and is now blocked off. 

Update - July 2, 2024 - Work is currently focusing on pier deck infrastructure and support buildings.  Final pile driving operations are set to start this week and last for approximately one week.  Please see the video at the bottom of this page for the latest changes to the harbor area.
