This is a solicitation document from the US Army Corps of Engineers, New Orleans District, for maintenance dredging services in Freshwater Bayou, Louisiana.

The solicitation number is W912P826BA017 and covers Freshwater Bayou Maintenance Dredging #26-2, located in Vermilion Parish, Louisiana, near the Lock to the Gulf project. The project involves dredging operations to maintain navigation channels connecting Freshwater Bayou Lock to the Gulf of America. The technical specifications include multiple channel cross-sections with defined bottom widths, side slopes, and elevation requirements. From existing channel conditions at CL STA -75+00 to CL STA -210+00, the project requires dredging to achieve target depths with bottom widths of 125 to 250 feet and elevation targets ranging from -16 feet to -30 feet mean low gulf (MLG). The channel profile shows required grade elevations with specific improvements needed from field wood pit approximation (El. STA. -15 ± 12.47 feet MLG) to the shiplochen area. Theoretical sections detail specific dredging cross-sections at multiple stations, with required side slopes and bottom width transitions. The project area includes Freshwater City Boat Slips, navigational aids (buoys marked RED and GREEN), discharge location limits in the Gulf of America, and beach nourishment areas. Conditions reflect survey data taken in June 2025, with all elevations shown in feet mean low gulf.
