Foundation & Site Development – magnitude of construction and bonding requirement up to $100M. Pumping Plant Construction (including supply, installation and start-up of pumps) – magnitude of construction and bonding requirement over $1B. Additional information regarding the scope of each action is included below.

23 April 2026. PROJECT SCOPE: The current design of the Yazoo Backwater Pumping Plant (YBWPP) is a 25,000 CFS pumping plant located adjacent to the Steele Bayou Drainage Structure. The pumping plant will be operated when the Steele Bayou Drainage Structure is closed and will manage water levels in the Yazoo Backwater Area to an elevation of 90 feet at the Steele Bayou gage during crop season (25 March - 15 October) and to an elevation of 93 feet at the Steele Bayou gage during non-crop season (16 October – 24 March). The following information is based on a 10% conceptual design. Scope and quantities will change as the design matures. Partial site development has been completed in the past including the completion of a partial cofferdam and partial completion of the intake channel. Additional required site development consists of clearing and grubbing, temporary and permanent site access, staging area(s), and establishment of government furnished borrow area(s). Some of these features of work may be completed under an initial site preparation and channel excavation contract separate from the pumping plant contract. Current design estimates excavation volumes of the intake and discharge channels to be approximately 700,000 CY. The resulting channels will be armored. Excavated material from the channels, cofferdam, or the pump plant location may be used as backfill for multiple project features and/or preload for the pump plant. The project includes an 800 ft length access bridge over the intake channel. The 25,000 CFS pumping plant is anticipated to be pile-founded. The pumping plant will contain 14 – 1,800 CFS axial-flow pumps with 5000 HP (approx.) electric motors and controls, gearboxes, etc. The Government will supply the power source under a separate contract prior to completion of pumping plant construction. The pumping plant building will be approximately 200 ft by 500 ft and includes a 75-ton overhead crane. Some of the structural features of the pumping plant include formed suction intakes, access tunnels, pump bays, discharge apron, trash rakes, stop logs, and retaining walls. LIST OF
