Some Sandy links:
(1) Subway Recovery:
In general I am really impressed with the speed of the subway recovery. If periodic flooding does not destroy the network, maybe New York does not need to relocate or build really expensive defenses, just take a 1 or 2 week vacation every hurricane.

We really need to invent/deploy gasoline-powered gas stations and refineries. It seems many stations had gas they could not pump for lack of electricity. Obviously lots of other problems as well, and I am sure there are risks of sparking near lots of gasoline, but this should be a solvable problem.
