It’s a modern-day fortress practically 20 years within the making, full with a “Nice Wall of Louisiana” and the largest pumping station on the earth – and it’s how New Orleans will do battle in opposition to the water that continually threatens to destroy it.
The huge community of levees, gates and floodwalls constructed to guard the New Orleans space within the wake of Hurricane Katrina’s devastation is lastly full. An occasion on Friday, days forward of the beginning of hurricane season, will formally mark that course of, in addition to the system’s handover from the Military Corps of Engineers to the state.
It’s an engineering marvel and, at a price of round $12 billion, to not point out one other $2.5 billion in associated initiatives, the largest of its type by the Corps.
Those that have seemed intently on the new system, designed to fend off so-called 100-year storms, or these with a 1% likelihood of occurring in any 12 months, say they’ve excessive confidence in it.
However they warning it might nonetheless be overtopped, and certain will. What’s completely different, they are saying, is that it’s now designed to protect in opposition to catastrophic breaches, significantly decreasing the chance.
The chairman of the state’s Coastal Safety and Restoration Authority, which is taking on the system from the Corps, calls it “one of many biggest engineering feats within the historical past of the world.”
“The extent of safety that’s across the Higher New Orleans space is healthier than at any time within the metropolis’s historical past,” stated Chip Kline. “We’re speaking about a few of the finest safety anyplace alongside the Gulf Coast and, fairly frankly, anyplace within the nation.”

‘Nice Wall of Louisiana’
Friday’s occasion is basically symbolic. The state has been regularly assuming management of the system for years as its varied parts have been constructed, and its important items have lengthy been in place. They handed a significant check in withstanding Hurricane Ida final 12 months, although a slight shift in path might have posed a better threat. The final components to be accomplished primarily concerned levee armoring, stated Corps spokesman Ricky Boyett.
Forecasters are predicting one other energetic storm season this 12 months, which might imply an additional check for the system. State officers are stressing to residents that it’s going to not get rid of all threat, and that individuals ought to make plans to evacuate if wanted.
The handover implies that two New Orleans-area flood safety authorities, the Southeast Louisiana Flood Safety Authority (East and West), will now be accountable for upkeep and operation.

Native officers and specialists expressed confidence this week in these authorities, the results of reforms handed after Katrina.

- The “Nice Wall of Louisiana,” in any other case identified by its technical identify, the IHNC-Lake Borgne Surge Barrier. It’s a 1.8-mile barrier that may be closed throughout storms. It spans the world the place the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet meet east of the town. Price: $1.2 billion.
- West Closure Complicated, close to the confluence of the Harvey and Algiers canals on the Intracoastal Waterway. The pumping station on the advanced is the largest on the earth. Price: $1.1 billion.
- The system spans a 133-mile perimeter. There are additionally 70 miles of inside threat discount constructions.
State and native officers can even want to watch subsidence of the soil atop which the levees sit, and when required, carry the levees again to their 100-year elevation, federal and state officers say.
Past that, levee armoring is in place to forestall erosion, as occurred in Katrina. For that motive, these conversant in the system stated this week whereas it’s excessive sufficient for 100-year storms, it stays efficient effectively past that, and may maintain even when the system is overtopped.
“The system because it’s designed ought to actually assist the town climate and survive an occasion that’s bigger than what one would count on to happen as soon as each 100 years,” stated Rick Luettich, a College of North Carolina at Chapel Hill professor who co-developed a storm surge mannequin the Corps utilized in designing the system and was a member of the east financial institution flood safety authority for eight years.
Ed Hyperlink, a College of Maryland professor who led the duty power that investigated the breaches in Katrina, stated he has “a heck of plenty of religion within the system” as a result of protections in place past the 100-year elevation stage to protect in opposition to breaches.
