South Branch Pike River

AUTHORITY:

Section 206, Water Resources Development Act 1996, as amended (Continuing Authority Program)

DESCRIPTION:

The South Branch Pike River flows north from State Highway 50 through the western areas of the City of Kenosha to County Highway 142 where it joins the Main Branch.

The project area is located in a rapidly urbanizing watershed with substantial urban and agricultural lands. Urbanization of the watershed has increased surface water runoff volumes leading to increased pollutant loads to the river. In its current state, the river exhibits flashy and powerful discharges, with high potential for erosion events during high flow conditions. Flooding, erosion, poor sediment control, degraded habitat, and impaired water quality are among the issues being addressed.

The purpose of the project is to restore the aquatic ecosystem to a more natural state.

In partnership with the County of Kenosha, Wisconsin, completion of the Feasibility Study Report (FS) would complete the plan formulation process, identify cost effective plans for ecosystem restoration purposes, and complete preliminary design of the recommended plan. This FS will serve as the decision document for the approval of construction funding. 

BENEFITS:

Potential alternatives could offset degradation and habitat loss by providing a sustainable environmental corridor and connect isolated environmental features; and restore the river to a more natural condition, and improve water quality and storage availability. 

COST:

Estimated Total Project Cost:

$15,775,000

Federal Cost:

$9,992,500

Non-Federal Cost:

$5,782,500

*This project was partially funded with Great Lakes Restoration Initiative (GLRI) funds received from U.S. Environmental Protection Agency.

STATUS:

The Federal Interest Determination was approved on Oct. 5, 2017, and the Feasibility Study has been initiated. It is anticipated that the draft Detailed Project Report and Integrated Environmental Assessment will be available for review in the fall of 2021.
