Feeling a little apocalyptic in here today, isn't it? First there was the news that another million people will be living in New York City by 2040, and there is nowhere near enough housing to accommodate them all.

The mayor's office Flickr feed has all kinds of graphs and charts, and the mayor will reveal his full preparedness recommendations this afternoon. In the meantime, NY1 has a preview, and possibilities include removable storm barriers placed into the sidewalk when there is flooding in the forecast; dunes in the Rockaway; and a storm gate at Newtown Creek. These measures are even more important given that the waterfront is where so many of the city's new arrivals are likely to live.
