Development projects may require a Clean Water Act (CWA) permit when wetlands need to be filled. Thus, developers of the Cainhoy Project — a more than 9,000 acre mixed use development in the Charleston, South Carolina — turned to the U.S. Army Corps of Engineers in 2018 for a CWA permit.The Justice Department’s Environment and Natural Resources Division (ENRD) defended the Corps’ decision to issue a permit.
