Creek Bank Stabilization

Like many other urban streams, Bassett Creek suffers from erosion caused by increased runoff. Over time, erosion builds up and clogs connecting ponds, eventually polluting Sweeney Lake and other local waterways.
To protect local water quality, the City of Golden Valley works with the Bassett Creek Watershed Management Commission (BCWMC) on projects to stabilize the creek banks and help control erosion.
Creek bank stabilization involves using a heavy layer of field stone and creating a buffer zone along the creek. Buffer zones on both sides of the creek stabilize the soils and filter pollutants with the help of riprap and native shrubs, trees, perennial grasses, flowers, and wetland plants. So instead of carrying eroded mud and sand toward Sweeney Lake and filling up connecting ponds, a stabilized Bassett Creek will retain its natural bends and pools that reduce harmful sediment.
Each year, City Public Works staff walk up and down Bassett Creek to identify problem areas. The City then works with the BCWMC to plan and implement projects that will address the problems.
