New York City’s recovery from Hurricane Sandy has been anything but perfect. Two weeks after the storm there are still sections of the city without power, water and heat, and the Brooklyn Battery Tunnel has only just reopened. But it could have been a lot worse, were it not for the city’s built-in emergency response resources. New York is so big and puts so much energy and money toward preparing for a terrorist attack or other such emergency, that the city itself already had more of the hardware and personnel required for recovery than a smaller, less-well-funded metropolis would. It’s like an economy of scale, but for disaster response.
