This document is a project plans file for the Big Bend State Fish & Wildlife Area (SFWA) Restoration - Phase 1 located in Whiteside County, Illinois, prepared in cooperation with the Illinois Department of Natural Resources (IDNR). The project involves the fabrication and delivery of water control structures and aluminum corrugated metal pipe (CMP) materials for wetland restoration work. Key bid items include mobilization, site preparation, embankment construction, water control structures (three aluminum full-round structures designated STR-1N, STR-1S, and STR-2), culvert pipe installation (24-inch and 36-inch aluminum CMP with flapgates), riprap placement (DU Class III and Class IV), removal of existing culverts and structures, soil erosion and pollution control, seeding and mulching, and traffic maintenance and control. The project encompasses two marsh areas with proposed full service levels (FSL) of 587.0 feet for the North Marsh (216 acres surface area) and 588.0 feet for the South Marsh (39 acres surface area). Construction details include five proposed berms with associated water control structures and aggregate spillways, with quantities specified for riprap delivery in tons requiring scale tickets with tare, gross, and net weights. The plans reference NRCS Conservation Practice Standards for critical area planting, dike and levee construction, mulching, and water control structures.

The project documents specify detailed construction requirements including non-woven filter fabric beneath all riprap installations, aluminum stoplog systems with specified elevation data for water control, and beaver deterrent configurations. Material quantities include DU Class III riprap ranging from 14 to 32 tons per structure location and aggregate surfacing for dike and road construction. All work is designated as either base bid or additional alternate bid items, with contractor responsibility for site staging repair, dewatering, and water maintenance considered incidental to the project. Construction safety is the sole responsibility of the contractor, and the plans note that all materials, data, and information are the property of Ducks Unlimited, Inc., requiring prior written consent for any use or reproduction. The project is identified with IDNR Project Number 1-23-043 and Ducks Unlimited project designation US-IL-193-5, with final plans dated April 28, 2025.
