New Orleans Levees, Floodwalls Hold Up to Ida After Billions Spent on Them Post-Katrina

Levees, floodwalls and floodgates in New Orleans withstood the harsh onslaught of Hurricane Ida after it made landfall Sunday, the Associated Press reported. The success of the protective installations comes after the federal government spent billions of dollars to upgrade them and marks a stark contrast to their failure 16 years ago against Hurricane Katrina.

While New Orleans' levees and floodwalls offered a barrier against Ida for New Orleans, some neighboring communities weren't spared. In LaPlace, a western suburb of New Orleans, work on a levee protection system only began recently, and many residents had to be rescued from flooding caused by the hurricane, the AP reported.

Marcia Jacob Hebert's LaPlace home wasn't flooded during Katrina, but she strongly believes that she'll find it flooded when she returns after evacuating in anticipation of Ida.

"We haven't had these problems until everybody else's levees worked," Hebert said. "It may not be the only factor, but I sure do think it contributes."

John Vincent, whose LaPlace subdivision was covered by floodwaters, also said it seems as if the water has risen faster since floodwalls were built in other communities farther east. He blamed a lack of coordination between parishes.

"It seems like now with any kind of storm it doesn't take anything to flood," said Vincent, 65.

Christina Stephens, a spokesperson for Gov. John Bel Edwards, said the pumps in New Orleans were working on generator power Monday and operating properly.

"The levee system worked the way it was supposed to," she said.

Two flood protection districts oversee the system in Orleans, Jefferson and St. Bernard parishes. Neither district reported any breaches or overtopping of levees.

"The system performed as designed," said Nicholas Cali, regional director of the Southeast Louisiana Flood Protection Authority-West, which oversees the west bank of Orleans and Jefferson parishes.

The Southeast Louisiana Flood Protection Authority-East, which covers St. Bernard Parish and most of Orleans and Jefferson parishes, also planned to inspect its system Monday but hadn't found any problems, according to regional director Kelli Chandler. A surge barrier opened Monday morning to allow maritime traffic through a major shipping channel, she said.

"We start preparing for a storm the day after the last one ended, and that's exactly what we're going to do today," Chandler said.

Tulane University history professor Andy Horowitz, author of "Katrina: A History, ​1915-2015," said it is "unequivocally great news" that the levees held up against Ida's surge. That doesn't mean that a city as vulnerable as New Orleans is safe from flooding "in the face of a changing climate," he added

"It does not mean that the lesson of Hurricane Ida is that metropolitan New Orleans has adequate hurricane protection. It means it had adequate protection against this storm surge," Horowitz said. "As the system is challenged by stronger and more frequent hurricanes. I think many experts are very concerned about the rather low level of protection that New Orleans has."

A federal judge in New Orleans ruled in 2009 that the U.S. Army Corps of Engineers' failure to properly maintain and operate the Mississippi River-Gulf Outlet was a significant cause of the catastrophic flooding during Katrina. Levee failures near Lake Pontchartrain also flooded New Orleans neighborhoods.

After Katrina, the federal government spent $14.5 billion on projects designed to enhance protection from storm surge and flooding in New Orleans and surrounding suburbs south of Lake Pontchartrain. Starting with a giant surge barrier east of the city, the system is a 130-mile (210-kilometer) ring built to hold out storm surge of about 30 feet (9 meters).

Work recently began on a levee project to protect tens of thousands of residents of LaPlace and other communities outside New Orleans' levee system. That project is not projected to be completed until 2024.

"I'm glad they're building us a levee, but I worry about what happens to the next group further to the west," Hebert said. "The water has got to go somewhere. We can't just keep funneling it from person to person, place to place."

Bernardo Fallas, a spokesperson for Phillips 66, said the company did not immediately have information about whether a reported levee collapse in Plaquemines Parish affected its Alliance Refinery in Belle Chasse. Fallas said the refinery has been shut down since Saturday, ahead of Ida's arrival.

"We will proceed to conduct a post-storm assessment of the refinery when it is safe to do so," Fallas said.
