About this file
The document is a construction contract for the Iowa Department of Natural Resources (IDNR) for the Hogsback WMA Wetland Restoration project located in Winnebago County, Iowa. The project involves constructing two dikes, conducting shallow water excavation, installing tiles, and performing drainage improvements in Section 9 of Township 100N, Range 23W. Key components include 1,150 cubic yards of on-site borrow excavation, 1,500 feet of tile investigation, 3,300 cubic yards of shallow water and principle spillway excavation, 5 tile breaks, 10 feet of 10" CMP with rodent guard, 1,940 feet of 8" non-perforated dual wall tile, 100 feet of straw wattles, and 25 tons of clean stone.
The project, identified as Project #25-02-95-01, requires contractors to access the site from 210th Avenue, with the DNR engineer providing specific location and elevation guidance. Contractors must strip 6 inches of topsoil from the embankment footprint, source borrow material from the wetland pool area at least 30 feet from the embankment, and compact materials in specified lifts. The tile installation will connect an existing intake in the right-of-way to a drainage ditch approximately 2,000 feet west, with a finished grade between 0.10% and 0.14%. Contractors are expected to maintain erosion control features and will be responsible for site preparation, material sourcing, and adhering to all applicable codes and ordinances.

Access from 210th Ave. DNR Engineer to provide the field location of the start and stop
1 of the dike work and will set an elevation hub
6" of topsoil shall be stripped from beneath the embankment footprint and stockpiled.
Barrow material for embankment shall be taken from the wetland pool area. Must stay
>30' away from embankment footprint to source material. Suitable material shall be compacted in lifts per specification. The final top grade may be obtained by placing 6"-
12" of topsoil to bring the final plan elevation as shown for the areas of the
2 embankments.
