Storm Inlet Painting Project

Each year local artists design and paint art on the downtown storm drain inlets to boost awareness that water that moves through the storm drainage system goes directly into the Big Sioux River with little to no treatment. 

Green Infrastructure Project

The City of Sioux Falls is implementing a green infrastructure project at properties in central Sioux Falls. Improvements will increase nature-based solutions for stormwater management, increase native plants and wildlife habitat, and provide community benefit and resilience.
