The Pheasants Nest Detention Pond Project was identified in the City of Brookings Drainage Master Plan, and ranked as a top three priority drainage project by the City Council because of the potential benefit to downstream residents. The purpose of the detention pond is to regulate peak stormwater flows and reduce sediment loads entering the existing downstream open-channel drainage system. The plan included regrading the entire 10.5-acre lot which created room for a future dog park, construction of a two-phase storm water detention and sedimentation pond, and an outlet flow control structure. Plans also included installing native grasses, trees, wetland flora, and pedestrian walkways. Two rain gardens were also included to handle direct runoff from the adjacent street before entering the pond. Since there was an existing wetland onsite, a 404 wetland permit application was submitted to South Dakota’s Regulatory Office and the pond construction work was authorized under an Army Corps general permit.
