Dredging for Naval Weapons Station Seal Beach (NWSSB)view on SAM.gov

This project involves dredging operations in open waters of the Pacific Ocean. The work requires dredging of approximately 80,000 cubic yards are sediment and placing the material within two separate placement/disposal sites. Critically, the project site is exposed to significant open ocean conditions including a high energy wave environment with typical wave heights in excess of 5 feet with extremely long wave periods and the potential for even larger wave conditions during storm events.Naval Weapons Station Seal Beach requires dredging for the inner approach channel at the entrance to Anaheim Bay, which is required to be maintained to a design depth of -41 feet Mean Lower Low Water (MLLW) and minimum width of 280 feet, as charted between the two arrowhead jetties to maintain navigational safety for Navy warships. Part of this dredging will take place in waters beyond the jetties.
