2/3 of Sandy-Damaged Homes in N.Y. Were Outside the 100-Year Flood Zone

The Atlantic

New York, and every other city, was built with certain climactic baselines in mind. This much rain, this much snow, this much heat, this many floods. They form a core set of assumptions about the kind of infrastructure the city needs. Institutions grow up around that set of givens; they are a fixed point in the otherwise tumultuous process of urban governance. Maps are created showing the 100-year flood zones; they show the places that have a one-percent change of being flooded in any given year. 

New York has to rethink, Mayor Bloomberg has realized. "The yardstick has changed, and so must we," he said in a speech quoted by the Journal. The rest of the country's cities and mayors won't be far behind.
