This contract involves constructing island enhancement features and an Ice Haul closure structure in the Mississippi River's Pool 9 backwater area to restore and protect bottomland forest habitat. Work requires using fine fill from habitat dredging and granular material from offsite stockpiles, plus placing riprap along selected shore areas for island protection. No specific timelines, budget amounts, or performance location beyond the Reno Bottoms area are mentioned. The project focuses on environmental restoration rather than new construction. Bidders should assess their capability for river-based habitat work and material sourcing.
