New York isn't the only city in the world (or country) that is exposed to storm surge damage. And, unlike many other cities, New York appears to have a relative easy way to protect itself.

The attached slides, from a 2009 deck, offer one potential solution to New York's storm-surge exposure — a porous barrier across the entrance to New York Harbor. According to the deck, such a barrier would cost $7 billion.

To put that $7 billion in perspective, its significantly less than the $12 billion price tag on one of our new aircraft carriers, the U.S.S. Gerald Ford.

So, whaddya say, folks? Time to consider a storm surge barrier for the country's biggest city? Or should we increase defense spending and build two-thirds of another aircraft carrier?
