The Minnesota soil stabilization project is St. Louis County’s largest waterway restoration project to-date
The St. Louis County Soil and Water Conservation District completed a $1.3 million restoration protect on 4,500 ft along Sargent Creek in western Duluth, Minn. This latest restoration, which included erosion control and soil stabilization measures, marks the district’s 15th completed stream restoration project in recent years, according to the Duluth News Tribune.
Sargent Creek was damaged by a 2012 flood that left behind wooden debris and eroded banks, which swept sediment toward the St. Louis River. The completed project included erosion control systems and an excavated floodplain.
“Now we have measured it just so when [water] rises, it spreads out and dissipates its energy,” said Project Manager Kate Kubiak. “Now it’s happy. It’s stabilized. It’s in the right slope.”
The restoration included erosion control blankets to manage bank side erosion and tree plantings to improve soil stabilization. The district estimates that approximately 100 dump-truck loads of dirt that get lost annually will remain on the creek’s banks.
At nearly a mile long, the restoration of Sargent Creek was the district’s largest project to-date. The project was sponsored by the state of Minnesota, the Department of Natural Resources Trails division, St. Louis County and the city of Duluth.
