Goodbye, New Orleans

By Mike Tidwell, OrionOnline.org. Posted December 9, 2005.

As we reach the 90-day mark since Katrina hit, it's time we ended our national state of denial. Turns out House Speaker Dennis Hastert had it right all along, though his reasons were flawed. We should call it quits in New Orleans not because the city can't be made relatively safe from hurricanes. It can be. And not because to do so is more trouble than it's worth. It's not. But because the Bush Administration has already given New Orleans a quiet kiss of death now that the story has run its news cycle.

As someone who dearly loves New Orleans and has experienced many of her charms, it pains me immeasurably to call for this retreat. This is not a rhetorical stunt or a shock argument meant to invite compromise talks. I mean what I say: Shut the city down and board it up before thousands more lives are lost.

In the weeks after Katrina, the American media somehow portrayed the catastrophe as a matter of failed levees and flawed evacuation plans. The "What went wrong?" coverage involved autopsies of every breached dike and a witch hunt for those responsible for the Superdome and Convention Center fiascos. But these were just horrifying symptoms of a much larger disease.

Katrina destroyed the Big Easy -- and future Katrinas will do the same -- not because of engineering failures but because one million acres of coastal islands and marshland have vanished in Louisiana in the last century due to human interference. These land forms served as natural "speed bumps," reducing the lethal surge tide of past hurricanes and making New Orleans habitable in the first place.

But while encouraging city residents to return home and declaring for the media audience that "we will do whatever it takes" to save the city, the President earlier this month formally refused the one thing New Orleans simply cannot live without: A restored network of barrier islands and coastal wetlands.

Tens of billions of dollars have been authorized to treat the symptoms -- broken levees, insufficient emergency resources, destroyed roads and bridges -- but next to nothing for the disease itself, that of disappeared land, which ushered the ocean into the city to begin with. No amount of levee building or stockpiling of bottled water will ever save New Orleans until the state's barrier shoreline is restored.

Just since World War II an area of land the size of Rhode Island has turned to water between New Orleans and the Gulf of Mexico, most of it former marshland. And every 2.7 miles of marshland reduces a hurricane surge tide by a foot, dispersing the storm's power. Simply put, had Katrina struck in 1945 instead of 2005, the surge that reached New Orleans would have been as much as 5-10 feet less than it was.

These marshes, as well as the barrier islands, were created by the sediment-rich flood waters of the Mississippi River deposited over thousands of years. But modern levees have prevented this natural flooding, and the existing wetlands, starved for new sediments and nutrients, have eroded and "subsided" and just washed away. Every ten months, even without hurricanes, an area of Louisiana land equal to Manhattan turns to water. That's 50 acres a day. A football field every 30 minutes!
