With the dispute over hurricane protection solutions for the outfall canals seemingly resolved, the Corps began designing and constructing predominantly “I-wall”-type floodwalls on top of the levee crowns. I-walls met the project goals of providing increased embankment heights within the limited existing rights-of-way with minimal disruption to the adjacent residential neighborhoods. Construction began in 1993, and project work along the outfall canals was reported to be nearing completion in 2005 prior to Hurricane Katrina.
