The BullStreet project involves the development of the old state hospital campus in downtown Columbia, SC, into a mixed-use community of retail, restaurant, office, hospitality, residential, and public space. The estimated $1 billion BullStreet project serves as the home to the Columbia Fireflies’ minor league baseball stadium. Davis & Floyd continues to lead a team of engineers, scientists, and landscape architects in the design of a new city park built around the daylighted stream channel. The park includes highly detailed stormwater management controls, floodplain restoration, and preservation of a grove of mature hardwood trees. The urban context and presence of utility mains along the creek corridor present a highly-constrained environment. The project included a comprehensive watershed scale effort in order to address urban flooding, improve water quality, and enhance the Smith Branch Creek. The Smith Branch valley is the spine of the BullStreet campus, but approximately 1,500 LF on the creek is contained in an enormous underground storm sewer designed to contain the 100-year flood.
