About this file
This is a construction plan set from the Iowa Department of Natural Resources for the Elk Lake WPA Wetland Restoration project (Project #24-01-21-01) in Clay County, Iowa. The project involves constructing a dike and water control structure to enhance a wetland at Elk Lake WPA, including installation of a 20-foot wide dike with 4:1 side slopes, emergency spillway, and water control structure. Key quantities include 2,700 cubic yards of embankment, 60 linear feet of 10-inch HDPE dual wall tile, 50 tons of erosion stone, 42 tons of clean crushed stone, and 20 feet of straw wattle. The plans contain detailed specifications for dike construction, emergency spillway design, and water control structure installation.
The construction plans specify that material for the dike must be hauled from a designated borrow area using only rubber-tired equipment, with 6 inches of topsoil to be stripped and stockpiled. The contractor must verify locations and elevations with the DNR inspector and conform to Iowa Statewide Urban Design Specifications. Additional requirements include DNR seeding of the site, disposal of excess materials, and maintaining erosion control features. The plans contain detailed engineering drawings showing dike sections, emergency spillway design, and water control structure specifications with elevations and dimensions.
