The U.S. Army Corps of Engineers, Charleston District, and the City of Charleston have partnered together to rehabilitate the city’s historic brick arch stormwater drainage system on the Charleston Peninsula and to support the design of the next phase of the Dupont-Wappoo Watershed Master Plan in West Ashley. This effort, authorized under a federal environmental infrastructure program, aims to improve stormwater management, enhance public safety, and strengthen the reliability of critical drainage systems in two of the city’s most flood-prone areas.
