Abstract : Plaquemines Parish, Lousiana, is composed of the lands adjacent to the Mississippi River below New Orleans, Louisiana. The New Orleans District has been directed by Congress to provide hurricane protection for the residents of Plaquemines Parish. The west bank portion of the project from Tropical Bend south to Venice is currently under construction by the sand core, hydraulic clay method, while work from Tropical Bend north to City Price has not begun. Eight plans for levee construction were initially considered for the northern segment, and two plans, sand core, hydraulic clay (SCHC) and 'I' wall, levee plug (I-Wall), were retained for detailed evaluation. The SCHC plan would provide appropriate hurricane protection, but would result in the loss of more marsh than would occur without construction of the project. The I-Wall plan would provide appropriate hurricane protection and would result in a minor loss of marsh. The SCHC plan has been recommended because of its performance in addressing the identified public concerns and its net positive contribution to the goal of National Economic Development. As a mitigative measure, it is proposed tht 297 acres of freshwater marsh be created on the Delta-Breton National Wildlife Refuge.
