Kevin Aylward: Katrina: Forget everything you thought you knew Kevin Aylward, The Examiner Aug 31, 2006
WASHINGTON - If you’ve only gotten your news about Hurricane Katrina from the mainstream media, everything you think you know about Katrina flooding New Orleans is probably wrong. On this first anniversary of the tragedy, while the networks congratulate themselves on their often wildly inaccurate reporting in the days following Katrina, there’s a far more important story not being told.
We’ve all heard the story: In the early morning hours of Aug 29, 2005, the Category 4 Hurricane Katrina roared ashore, overwhelming the New Orleans levee system and flooding the city. That story is, frankly, an urban legend.
In the year since Katrina, we’ve learned that the storm was a Category 1 by the time she hit New Orleans. We’ve also learned that the primary levee breach — the one that caused 70 percent of the flooding in the city — was not caused by the storm surge but by poor engineering.
After months of dissembling and obfuscation by the U.S. Army Corps of Engineers — the designers of the levee system — the Corps was forced to admit what all the outside experts were saying; critical engineering mistakes caused the walls that were supposed to protect the city to collapse before they were overtopped by the storm surge. And on the east side of the city, the flooding was largely caused by a shipping channel the Corps dug three decades earlier.
The Great Flood of New Orleans was not a natural disaster but a man made one.
What was not really told to the public however is how quickly the floodwalls in the city collapsed — how high the water got up the walls before they failed. This is an important question to a city rebuilding — $250 billion in infrastructure. It is commonly assumed by the public that the water must have been quite high.
A newly released video, taken by New Orleans firefighters as the 17th Street Canal floodwall was actually in the process of breaking during Katrina, shockingly, seems to dispute that.
The video, taken while the damage in the floodwall is still limited to meters and not city blocks shows the water in the canal at near normal levels. (The wall fell over a period of about two hours.)
The real importance of the video comes from looking not at the breach itself, but at the wall of the canal where the water appears to be less than 1 meter above normal. City planners were hoping that only 2.5 meters of water would enter the canal.
Months after the storm, it was reported that water had been seeping underneath the levee for almost a year near the break. Homeowners in the area reported it, but the report never got into the right hands.
Engineers had not properly accounted for the soil conditions in the area and the pilings supporting the wall were not long enough, allowing water to come under the levee.
Poor soils in the area, engineering blunders, bureaucratic snafus, but only a little water conspired to wash out the foundation of the floodwall and produce the majority of New Orleans’ flooding.
Surprisingly, the video gives us every indication that New Orleans was doomed with or without Katrina. The amount of water in the canal was not unusual and, in fact, that wall had held far more water on previous occasions; that was before it was undermined for the better part of a year.
All this leads to the even more shocking conclusion that Hurricane Katrina probably saved 50,000 lives.
That levee was doomed. While Katrina was the last straw, it was destined to fail. Studies done before the storm indicated that if a major hurricane overwhelmed the city’s levees, as many as 100,000 people would die as a result.
If the levee had failed without warning, there would have been no evacuation, no preparation, no state/federal support, no Coast Guardsmen in helicopters etc. If you think Katrina was bad with governmental preparations, consider an event half that size without it.
To be sure, while this single floodwall accounted for the majority of the flooding in New Orleans, the story does not end there. Even without the 17th street canal wall failing, there would have been significant flooding especially to the east side of the city and the Gulf Coast would have been hammered either way.
But the story of the flooding in New Orleans that the media is telling is largely wrong.
The Great Flood of New Orleans was not a natural disaster. It was an engineering disaster bound to happen sooner or later.
