This project is focused on the identification of USACE infrastructure that is scheduled (or anticipated to be scheduled) for repair or replacement. USACE coastal navigation assets include: 1,067 navigation projects, 19 lock chambers, 13,000 miles of channels, 929 navigation structures, and 844 bridges. USACE inland navigation assets include: 27 inland river systems, 207 lock chambers (at 171 lock sites), and 12,000 miles of inland river channels. Many of the structures associated with these assets are in need of repair or replacement. This project seeks to incorporate EWN alternatives into project designs.
