Columbia Circle Drainage Channel Improvements

Columbia Circle Drainage Channel Improvements


Sioux Falls, SD

Previous Next

Richmond Estates 2nd Addition in northwest Sioux Falls was constructed in the mid-1980s. Over the years, continual degradation of an existing stream channel which flows in the backyards of residential lots created concerns with shallow sanitary sewer crossings. Scour issues at the downstream end of storm drain outlets feeding the drainage channel between Bahnson Avenue and Sycamore Avenue north of 3rd Street also required action by the City to resolve the drainage channel issues. Banner was contracted for the design of grading, storm sewer, and sanitary sewer improvements. Numerous permanent utility and temporary construction easements were necessary to complete the work. The design incorporates a low flow pipe to carry trickle water through the area, two rock drop structures to dissipate energy within the drainage channel, and reestablished safe and protected sanitary sewer crossings in the area.
