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 at least 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 on January, 21, 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 - August 8, 2022 - Short periods of pile driving to be heard over next several weeks:  

Construction contractors have determined that they could speed up a small subsection of the pile driving if it were to occur much earlier than anticipated.  Due to this, approximately 20 piles will be driven over the next several weeks starting on August 9.  Pile driving will occasionally be heard during this period.  Work building up molds for the new pier and pouring marine concrete to create the pier deck is continuing.  These steps will be done in phases throughout the remainder of the year, and may include periods of weekend or early morning work.  Additional short phases of pile driving will be required later in the project.
