## Description

**Update 0003 issues amendment 0002. Some clauses were added and removed, and the bid due date was updated. **Update 0002 updates Amendment 0001. One of the plan sheets ID number had a typo in it. Revised amendment 0001 posted.

Amendment 0001 published 8.20.2025 - updated 5 pages on the drawing set. 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.
