The New York City Open Accessible Space Information System Cooperative, aka NYC OASIS, has updated its map to include the latest property data, as well as coastal storm impact zones (above). This map joins climate change rallies and drenching Nor'easters as an indication of where city can get really soggy. The city also has a Hurricane Zone Finder.

The Intergovernmental Panel on Climate Change released a report saying the city will flood, what with rising sea level and even more frequent storms on the horizon. Related: Here is Mayor Bloomberg's Sunday 1010WINS speech about reducing greenhouse gases - he emphasizes the city's "coastal" locale.
