Description

The City of Charleston is seeking an engineering firm to provide professional engineering services for the Dupont Wappoo Watershed Improvements Project. The project aims to develop and evaluate flood mitigation improvements within the Dupont Wappoo drainage basin, covering approximately 1,600 acres in the West Ashley area. The basin relies on a central drainage channel constrained by limited maintenance access, undersized capacity, and tidal influences. Phase One services include developing a conceptual preliminary engineering and planning package for transfer to the U.S. Army Corps of Engineers for future final design and construction.
