United States Army Corp of Engineers- Flood Protection Project, Big Sioux River and Skunk Creek
In 2005, the US Army Corp of Engineers completed Flood Protection Project drawings for the City of Sioux Falls. The design would protect the City against a 100 year flood event with an additional three feet of free board. Unfortunately that same year, hurricane Katrina hit and as result federal funds where redirected to the city of New Orleans including funds for this project. The project came back the following year in phases.
In 2006 the first phase of this project started. SFC Civil Constructors bid and was awarded the construction of three drainage structures and a retaining wall at Sertoma Park.
In 2010 we bid and were awarded the construction of the new flood control dam north of Skunk Creek and Big Sioux River confluence. This dam had ten automatic gates and was constructed using color concrete and form liner. We also were awarded the construction of 1500 linear feet of concrete flood wall by the Minnehaha Country Club and the replacement of eight drainage / gate structures.
In 2011 the final phase of the project was bid for the rehabilitation of the existing diversion dam north of Sioux Falls Regional Airport and included replacement of fifteen drainage structures and six flood closures. The dam rehabilitation included replacement of existing gates and automatic gate control operators.
Total contracts for SFC Civil Constructors was over $13,340,000.00
