BullStreet Mixed-Use Development

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.

Our team surveyed approximately 150 acres; designed master plans for water, sewer, and stormwater structures; and relocated 6,000 LF of 15” and 18” sewer mains. We also designed phase I and phase II infrastructure, totaling more than 8,000 LF of roads and utilities. We completed an early site package grading plan and utility plan for Spirit Communications Park, home of the Columbia Fireflies. In addition, we managed the 3,000 LF Smith Branch Stream Restoration Project and performed civil site design for a five-story, 125,000 SF office building with parking underneath; Town Park, a 28-unit townhome project on 1.25 acres; Parker Annex, an existing structure that was renovated for a two-story, 9,200 SF office building; and Bakery Building, an existing structure that was renovated into a one-story, 4,800 SF office building.
