The Army Corps of Engineers says a federal levee designed to protect Terrebonne Parish and parts of Lafourche Parish from storm flooding will cost $12.9 billion. State and local officials would have to come up with 35 percent, or up to $4.5 billion.
The plan released Friday includes 36 additional miles of levee, extending the Morganza project from U.S. 90 in Gibson to Louisiana Highway 1 in Lockport.
The corps plans a meeting about it Jan. 31 at the Houma Municipal Auditorium.
