Market Street Drainage Improvements – Divisions I, II, III
With approximately 4 million visitors each year, Charleston’s Market Street corridor is known for its beauty and rich history, but it also is notorious for its frequent flooding. The City of Charleston requested that Davis & Floyd provide engineering services to improve the drainage capabilities on Market Street and surrounding areas.
The project was split into three divisions:
Division I - upgraded the existing stormwater pump station near the South Carolina Aquarium to accommodate additional flows from the Market Street drainage area
Division II - developed a 9-foot-diameter tunnel approximately 140 feet beneath Concord Street and Market Street connecting the Market Street drainage area to the pump station
Division III (currently being designed by Davis & Floyd) - design of the near-surface stormwater collection system and streetscape improvements including expanded sidewalks, multiuse lanes, new landscaped areas, and undergrounding of overhead utilities to improve the aesthetics and pedestrian flow along the corridor
Coordinating with the Downtown Market Merchants Association, City of Charleston, and SCDOT to develop construction staging plans and schedule
Designed a stormwater system to help alleviate flooding on Market Street and surrounding areas.
