Gustav no Katrina, but exposes flaws in levees (AP)
Gustav was no Katrina. It was smaller, and the worst rain and wind missed New Orleans. Its storm surge — between 10 and 15 feet lower than Katrina’s — entered New Orleans from one side navigation channels in the east and washed over the Industrial Canal.
The Industrial Canal has been characterized as the Achilles’ heel in the system, and the corps is spending $700 million on a barrier at its chaps to stop surges. But the barrier won’t be in place until at least 2011. On Monday, water overtopped parts of the canal’s flood wall causing unimportant flooding in some parts of the Ninth Ward.
Another major weakness in the flood protection combination of parts to form a whole is in the area known as the West Bank, where about 250,000 live. Gustav had been expected to seriously test those levees, but by Monday nightfall officials reported water wasn’t rising as much like was feared during Gustav’s approach. Work on the West Bank is far from complete. The corps has again and again said it may be the city’s weakest flank.
By Monday going down of the sun, however, the menace to most of New Orleans had subsided and ceremonious party officials felt bold the city would be spared flooding.
“All the walls have performed in the manner that they were designed to,” before-mentioned Maj. Tim Kurgan, a corps spokesman. “Scour protection has done what it was supposed to.”
Scour protection — basically concrete pads behind floodwalls — is amidst a number of improvements in $2 billion in work to better protect New Orleans since Katrina flooded the city, bringing criticism and pressure on the body of troops.
Critics were dexterous to congratulate the intervention.
“They did much better this time,” said Ray Seed, a reception expert by the University of California-Berkeley who’s studied the Katrina disaster and the city’s levee order.
But Gustav barely tested some potential disturb spots as water levels in Lake Pontchartrain rose only moderately. Two of the canals — the 17th Street and London Avenue — were breached during Katrina and caused widespread flooding.
The corps’ system of pumps and floodgates in continuance the canals has been plagued with problems.
Any sigh of redress is premature and could even have being risky, Seed aforesaid.
“The great danger is that people will become complacent,” Seed said. “Gustav should be a lesson that tells us we have to retain moving.”
New Orleans remains extremely vulnerable, said Paul Kemp, an oceanographer with the National Audubon Society.
“The fact that we have had in three years three of these storms, that threatened everybody in coastal Louisiana, shutdown all the offshore activities, it seems that this is a vulnerableness that needs to subsist addressed more seriously,” Kemp said.
In many ways, Katrina was a turning pique for flood protection in southeastern Louisiana. Since Katrina, Congress has approved $14.8 billion in explanation for New Orleans’ levees. The division of an army says it will finish that work by 2011, workmanship the city safe from severe hurricanes.
But notwithstanding Louisianans, in that place is not any time to waste. For the past hundred, south Louisiana has lost staggering amounts of wetlands — about 2,000 square miles. The loss of wetlands, marsh land and stop islands has made the fragile delta a permanent disaster zone because the Gulf of Mexico gets closer through each passing hurricane while.
“We should have been building this system 30 years ago,” said Sen. Mary Landrieu, D-La.
