The enhanced levee system is designed to significantly reduce the risk of flooding in Greater New Orleans during extreme weather events, such as a 100-year hurricane. The integration of oyster reefs into the infrastructure not only mitigates wave energy but also supports ecological benefits, such as providing habitats for marine life. However, the study underscores the importance of proper design and construction to avoid failures like those seen during Hurricane Katrina. Without adequate flood protection, residential areas in New Orleans remain vulnerable to severe damage and loss of life during major storms.
