In the wake of Hurricane Sandy, New York looks at sea walls. So will we.
Hurricane Sandy whacked New York so hard, in many quarters it’s still reeling. That superstorm surge of water, roaring over Staten Island and the Rockaways, into New York Harbor, over Lower Manhattan, over Wall Street, into subways and power stations. Into the heart of the biggest city in America. It’s already cost billions.
It will cost billions more. Now, some are saying it’s time to build a wall. Not little old-fashioned sea walls, but super storm barriers. Mighty barricades and huge harbor gates to hold out the sea.
This hour, On Point: barricading New York against a rising sea.

From Tom's Reading List
ABC News "In the wake of superstorm Sandy’s massive destruction to coastlines in the East Coast, many experts suggest that a sea wall barrier could have minimized the deadly storm surge that swept away homes and knocked out power to millions."
Time "It was called the Watersnoodramp, which in Dutch means “flood disaster”—and it certainly was. The North Sea flood of 1953 was the result of a high spring tide that met a strong storm, resulting in a storm surge that inundated the countries around the sea. Lives were lost in England, Scotland and Belgium, but the worst of the surge was felt in the Netherlands. The dikes and other sea defense built around the coast of the Netherlands were unable to defend against the surge, and nearly 2,000 people died in the ensuring flood. (Just to put that in perspective, the equivalent loss of life in the U.S. today would be over 60,000 people.) In a below sea-level nation that had always warred with the tides, the 1953 flood proved one of the worst in the history of the Netherlands."
New York Times "After the enormous storm last week, which genuinely panicked New York with its staggering and often fatal violence, residents here could certainly identify with the first line of Benchley’s note. But what about the second?"
