Levees 'relatively' unscathed, Corps says
09:38 AM CDT on Sunday, September 7, 2008
The Army Corps of Engineers said Saturday that its storm protection system survived Gustav relatively unscathed.
The corps finished its assessments of levees and floodwalls following Hurricane Katrina in all parishes but Terrebonne, where 95 percent of the review has been done.
A railroad crossing on the western side of the Industrial Canal under the Almonaster Bridge is what the Army Corps is calling one of its priorities of action following Hurricane Gustav.
The storm surge dug up dirt near the floodwall. That’s one of five spots in the metro area that the corps says is in need of emergency repairs.
“I think most of the problems we found were relatively minor,” said Col. Al Lee of the Army Corps of Engineers.
Also on that priority list is a gate at the company canal the corps needs to be properly sealed, railroad gate in St. Bernard Parish, another gate at a sewerage and water board pump station, and a levee in grand isle.
“I don't think any of them are major repairs we have to do in the system,” Lee said.
The most significant repairs needed appear to be down in Grand Isle, where Army Corps officials said Gustav's surge destroyed part of that levee and another section where construction was recently completed was mostly destroyed.
“We are focused on this because we have concerns that everybody knows that Hurricane Ike could impact the gulf,” Lee said.
That's why the Army Corps said Saturday they're investigating temporary repairs, using what engineers call a burrito levee.
“It's a geo-tech style fabric that's is basically used as a wrap, just like you would with a burrito. You fill it with clay materials, then you wrap it. And then it would be secured together, and then you would use sand to hold in place,” Lee said.
But the Army Corps said Saturday it's possible all of Grand Isle will not be protected by this interim protection.
“If we're not able to do the entire island, we will prioritize the most critical areas of the island and flood fight those areas first,” Lee said. “Our goal of course would be to flood fight the entire island. But if time does not permit us to do that, then we will identify the most critical areas of the island and flood fight those first.“
The corps says many of the other critical projects will be completed by mid week.
They signed an imminent threat letter that gives them authorization to prepare for any future storms.
