Copper Creek Mixed-Use Development

Sioux Falls, South Dakota

Copper Creek Addition is a 219-acre subdivision featuring commercial, office, multifamily, and single-family development. The City of Sioux Falls had identified the property as a location for a regional stormwater detention and BMP as well as a route for a sanitary trunk sewer to serve the eastern edge of the City. Throughout the design and construction, Brosz Engineering worked with the City of Sioux Falls to incorporate the regional detention and the sanitary trunk into the overall design and utilize these features to enhance the drainage and aesthetics of the neighborhood.

Brosz Engineering was responsible for the initial Master Plan, preliminary engineering, final engineering, mass grading, erosion control design, and performed hydrology and hydraulic analysis for the site including detention pond and channel configuration. Brosz also produced the construction documents for the installation of all project infrastructure, including streets, water distribution, sanitary sewer, and storm sewer.
