This is a solicitation cover sheet and design documentation for a federal dredging contract issued by the U.S. Army Corps of Engineers, New Orleans District. Solicitation No. W912P826BA015 covers maintenance dredging operations for the approach channels serving the East and West Calumet Floodgates located in Bayou Teche, St. Mary Parish, Louisiana. The project file number is H-16-48785 (ED-26-005), with the contract number designated as W912P826CXXXX. The solicitation was submitted in June 2025 with an approval date of April 23, 2025.

The dredging work involves excavation of sediment from two separate approach channels—one serving the West Calumet Floodgate and one serving the East Calumet Floodgate. The required dredging grade transitions from elevation -8.0 MLG (Mean Low Gulf) at stations 0+00 to 0+50 to -9.0 MLG from station 0+50 through the dredge limit at approximately stations 5+75 (West Calumet) and 5+80 (East Calumet). Excavated material must be placed beyond the -35-foot contour in Wax Lake Outlet. The channel widths are 107 feet (West Calumet) and approximately 107-128 feet (East Calumet), with the contractor required to note that channel dimensions transition both vertically and horizontally in the plan and profile views. Vertical control is referenced to a staff gage located on the East Floodgate wall, with gage zero established at 0.0 feet NGVD equivalent to +0.78 feet MLG.
