Location/Description

The study area is located in a rural setting in western Hennepin County, Minnesota, approximately 40 miles west of Minneapolis, Minnesota.  The Crow River, a tributary to the Mississippi River, experienced erosion on a reach north of the city of Delano, Minnesota, where the natural course of the river follows a sharp turn adjacent to County Road 50.  Erosion at the outside bend of the channel and at the toe of the bank of the Crow River threatened the stability of County Road 50 at the top of the river bluff. 

Erosion was as close as 10 feet from the edge of the road and posed a potential public safety hazard.  Stabilization required a complete reconstruction of the slope within the project limits.

Status

A feasibility study was completed and approved in May 2011.  A project partnership agreement was executed July 2011 between the Corps and Hennepin County, who is the local sponsor for the project.  The original construction contract was awarded February 2012, and construction was completed in 2013. 

Following construction, sliding of topsoil started at both the upstream and downstream ends of the project at the tie-in locations.  This problem does not pose a threat to public safety.  Due to the fiscal limits in place at the time, the U.S. Army Corps of Engineers was unable to repair the damaged slope.

In March 2017, the U.S. Army Corps of Engineers received approval from the Assistant Secretary of the Army (Civil Works) to increase the federal Section 14 project limit to $5 million, as authorized by the Water Resources Reform and Development Act of 2014.  The local sponsor and the Corps signed an amendment to cost sharing agreement on September 29, 2017.  The Corps and the local sponsor are pursuing a design-build acquisition strategy for the repair.  The Corps will be awarding a design-build contract in early 2019, with construction planned by the end of 2019.

Authority

Emergency Streambank Erosion or Shoreline Protection is a Continuing Authorities Program, authorized under Section 14 of the Flood Control Act of 1946, as amended.  The Hennepin County Board of Commissioners requested the project on October 17, 2008.

Fiscal

The design and implementation phase of the project is cost shared at 65 percent federal and 35 percent non-federal up to the Section 14 federal funding limit.  The estimated remaining cost of the project is approximately $1.5 million.
