Lake Borgne Surge Barrier designed and built after Hurricane Katrina to keep storm surge from entering the Inner Harbor Navigation Canal

On Friday at Headquarters, the Army Corps revealed the impact of New Orleans’ post-Katrina flood protection on neighboring communities.

The Corps’ report says the $10 billion improvements may have been responsible for adding an average of 1 inch in surge heights during Isaac. It said LaPlace saw a slightly lower surge due to the betterments.

The Corps will hold a series of public meetings for the affected communities beginning at 6 p.m. with an open house, followed by presentations at 6:30 p.m.:

• Tuesday, Belle Chasse Auditorium, 8398 Louisiana 23, Belle Chasse
  
• Wednesday, North Shore Harbor Center, 100 Harbor Center, Slidell
  
• Thursday, St. John Community Center, 2900 U.S. 51, LaPlace
  
• Monday, Nov. 19, Jefferson Parish General Government Building, 200 Derbigny St., Gretna
