Scope
Norfolk District and the Virginia Port Authority are currently in partnership for the design and construction of the Norfolk Harbor and Channels Navigation Improvements Project, Virginia. This multi-phase priority project includes the expansion and deepening of the current F Anchorage and its associated approaches.
Background
The Norfolk Harbor and Channels deepening was authorized by Congress for construction in Section 201 of the Water Resources and Development Act of 1986 following an approved study. The Chief of Engineers signed a Chief's Report for the Norfolk Harbor Navigation Improvements Project on June 29, 2018.
Anchorage F is currently designed and maintained as a 3,000-foot diameter circle for free-swinging bow anchoring. The anchorage lies withing the designated F Anchorage Area, due west of the Hampton Roads Bridge Tunnel (HRBT) and northwest of the Norfolk Harbor Entrance Channel.
Virginia Port Authority, the non-Federal sponsor, requests a modification to the existing USACE project authority to include a deeper and wider Anchorage F and approach based on Virginia Pilot Association surveys, U.S. Coast Guard guidelines and a design charette conducted on October 5, 2020. A deeper and wider anchorage would align with the authorized depths of the surrounding federal channels.
Pursuant to the National Environmental Policy Act (NEPA), USACE plans to prepare supplemental NEPA documentation to evaluate impacts from reasonable project alternatives and to determine the potential for significant impacts. As a result of the General Re-evaluation Report, dated June 29, 2018 and authorized by Section 1403 of the Water Resources Development act of 2018. Anchorage F has an authorized diameter of 3,620 feet and depth of -51 feet. Dimensions greater than -51ft deep x 3,620 ft in diameter must be coordinated with appropriate environmental agencies. The EA will be integrated into the Post Authorization Change Report.
