This is a Solicitation for Maintenance Dredging in the Sandy Hook Channel, New Jersey, issued by the US Army Corps of Engineers New York District. The solicitation (W912DS25BA009) is dated August 2025 and covers a Federal Navigation Project for dredging specific areas in the New York Harbor. The project includes three dredging areas: Area A (base requirement), Area B (option), and Area C (option), with specific requirements for slope removal and dredging methodology. The project involves maintaining the navigation channel, with survey dates planned for September 23, 24, and 26, 2024.

The documents provide detailed technical specifications, including channel coordinates, sounding maps, and project site plans. Key technical details include dredging to a -35 foot Mean Lower Low Water (MLLW) depth, with specific guidelines for slope gradients and material placement. The project includes a designated Sea Bright Offshore Borrow Area (SBOBA) for material placement, with precise coordinates and restrictions on material transport. The contract is structured with base and optional components, allowing flexibility in project execution based on funding and operational requirements.
