Continuing Authorities Program: Emergency Streambank Protection, Section 14, Dunn County Highway M

An area of County Highway M along the east bank of the Red Cedar River northeast of Colfax, Wisconsin is being threatened by erosion. The erosion is occurring along the outside bend of the river. Based on surveys, a stretch of river bank that is approximately 500 feet long is actively eroding where the top of bank has encroached on the right of way for County Highway M. Currently the top of bank is within 10-15 feet of the shoulder at the center of the site. Further erosion would lead to a significant safety concern as the bank drops off approximately 50 feet to the water surface below.
