Morganza, Louisiana
to the Gulf of Mexico Risk Reduction
Project
Purpose. Reduce hurricane and flood
damages in an environmentally sustainable manner in the Houma area. The project will protect over
150,000 people and 130 square miles of saline and fresh marshes, farmlands,
heavy and light industry, residential, and other developed areas. Protect
development and the remaining fragile marsh from hurricane storm surge.
Location. Coastal Louisiana
approximately 60 miles southwest of New
Orleans, and includes portions of Terrebonne and
Lafourche Parishes. The area is bounded on the west by Bayou Du Large and
State Highway 311 and on the east by Bayou Lafourche. The southern boundary
is the Gulf of Mexico.
Sponsors. The Louisiana Department of Transportation and Development
(LADOTD) acted as the local sponsor for the feasibility study and has been replaced by the Louisiana Coastal Protection and Restoration Agency (LACPRA) who has agreed
to sponsor detailed design and construction. Terrebonne Levee and
Conservation District (TLCD) will provide Operation, Maintenance, Repair,
Rehabilitation and Replacement (OMRR&R).
Authority. A Reconnaissance Study for the Morganza, Louisiana to the Gulf of Mexico Risk Reduction
Project was authorized by Congress in 1992. Following completion
of this report, Congress authorized a Feasibility Study in the Energy and
Water Development Appropriations Act of 1995 (Public Law 103-316). The
Feasibility Study was completed in March 2002 and the Chief of Engineers letter
was forwarded to the Secretary of the Army in August 2002 and supplemented in
July 2003.
Features. Approximately 72-miles of earthen levee, ten 56-foot wide
(sector gate) navigable floodgates, three 125-foot wide (sector gate)
navigable floodgates, 12-multi barrel water control structures, 13-tidal exchange structures and a lock
complex consisting of a lock in the Houma Navigation Canal measuring 110-feet
by 800-feet, an adjoining navigable floodgate (sector gate) measuring 250
feet wide, and a dam closure. The structural features are integrated into the
levee alignment to provide flood protection, drainage, environmental
benefits, and navigational passage. Construction of this plan is estimated to
cost $912 million (2007 price level) and would be cost shared 65% / 35% with
LADOTD, the local sponsor.
