MRGO Deep-Draft De-Authorization Study

In 2006, the USACE began a study to develop a plan to de-authorize deep-draft navigation on the portion of the MRGO between the Gulf Intracoastal Waterway (GIWW) and the Gulf of Mexico. The goals of the study were to develop a comprehensive plan to de-authorize deep-draft navigation, evaluate any navigation functions that should be maintained, identify measures for hurricane and storm damage reduction, and to refine the plan to be fully integrated and consistent with the Louisiana Coastal Protection and Restoration (LAPCR) Plan.

The final Deep-Draft De-authorization Report was sent to Congress on June 5, 2008, officially de-authorizing the channel from the GIWW to the Gulf of Mexico and authorizing the construction of a rock closure structure, removal of aids to navigation, and release return of real estate easements. The USACE is currently preparing the MRGO Ecosystem Restoration Plan Feasibility Study which will supplement the MRGO Deep-Draft De-authorization Report.
