Kinnickinnic River Rehabilitation


During the 20th Century, a section of the Kinnickinnic River in Wisconsin had been turned into a channel that, over the decades, had become an urban eyesore.


The SEH project team helped completely rebuild the watercourse by removing the concrete channel, rehabilitating 1,000 feet of land and lining with stone, stabilizing the embankment and constructing retaining walls. A multi-use path was also added for recreational and maintenance use.
