Existing levees will be raised in two northeast Louisiana parishes starting in the next few weeks.
The levees held during the Mississippi River flood of 2011, but have settled gradually since being built in 1973.
Reynold Minsky is president of the 5th Louisiana Levee District board. He tells The News-Star of Monroe the changes will bring all of East Carroll Parish and most of Concordia Parish to 500-year flood protection levels.
A marsh management levee that is expected to become part of Terrebonne Parish's Morganza hurricane protection system was severely damaged during Hurricane Isaac.
The Courier reports the storm's tidal surge destroyed one of the levee's water control structures, washing it away and leaving behind a 50-foot gap.
Terrebonne Levee Director Reggie Dupre said the levee, which crosses open water in the Wildlife and Fisheries' Pointe-aux-Chenes Wildlife Management Area in Montegut, has caused repeated headaches for the levee district.
