The City of Sioux Falls requested DGR Engineering’s (DGR) services in 2014 for improvements to a small drainage channel which was undersized, and some adjacent properties and structures had previously sustained flood damage during large rain events. After initial concepts were reviewed, the City opted to have DGR design the channel to handle more capacity, which required making the channel deeper and wider.

The project was put on hold for various reasons, but after almost ten years of coordination, design, and construction, this drainage channel project was finally completed in the summer of 2023. The contractor and subcontractors did an amazing job revitalizing an area that had been neglected and overgrown, and the property owners along Riverdale Road are now better protected against future flooding.
