Welcome to the United States (U.S.) Department of the Navy's website for the Naval Weapons Station Seal Beach Ammunition Pier and Turning Basin Environmental Assessment (EA), an online resource for information about the proposed Ammunition Pier and Turning Basin at Naval Weapons Station Seal Beach, located in Seal Beach, California.

The U.S. Navy has prepared a Revised Draft EA for the proposed Naval Weapons Station Seal Beach Ammunition Pier and Turning Basin project. The Navy prepared a Draft EA in April 2017 to analyze the potential impacts of constructing a replacement ammunition pier, associated waterfront facilities, causeway, truck turnaround, and a new public navigation channel. During the project design phase, the Navy determined that certain design elements analyzed in the 2017 assessment would need to be updated and a Revised Draft EA prepared. 

Notable project design changes analyzed in the Revised Draft EA include:

  • Increasing the number of concrete piles
  • Widening the south mole
  • Increasing the size of the truck turnaround
  • Widening the causeway (raised road)
  • Changing the width of the public navigation channel
  • Dredging to occur for approximately one year, 24 hours a day, seven days a week
  • Adding rock revetments on both sides of the public navigation channel
  • Lengthening and changing the configuration of the floating security barrier
  • Revising the construction timeline
  • Changing the lighting design

The proposed pier and associated facilities would replace the existing wharf, which is more than 60 years old, was built before the inception of modern seismic codes, and is past its design life. The new pier would be built to current earthquake standards, would be able to support future fleet requirements, and would provide greater separation between Navy operations and civilian transportation routes.

In the Revised Draft EA, the Navy incorporated changes in the proposed design and construction of the pier since publication of the Draft EA in April 2017. The Revised Draft EA was made available for public review and comment, and an open house public meeting was held to inform the community of project design changes.
