Last year on this date, children in Dumbo, in view of the Manhattan Bridge, waded through floodwaters brought on by Hurricane Irene, which weakened to a tropical storm just before hitting shore at Coney Island. Two years prior to Irene, 100 scientists and engineers met to sketch out a bold defense: massive, moveable barriers to shield New York City from a storm-stirred sea. The network would protect Manhattan and parts of the four outer boroughs and New Jersey, but not some vulnerable swaths of Brooklyn and Queens. AP Photo
