Sandy and Redundancy

New York should be thankful it has bridges as well as tunnels, just as after the 1989 earthquake, The Bay Area was glad it had the BART Tunnel in addition to the temporarily damaged Bay Bridge. Redundancy has many dimensions, both multiple paths with the same technology and multiple technologies serving similar ends. But redundancy is not the only key to reliability.

In addition to spending on prevention (of storms, i.e. weather control and climate management), we need to spend on defense (sea barriers), mitigation (pumps), and in some cases accept the damage. It seems New York primarily (and by default) chose the ``accept'' strategy this time. In the future there should be a more multi-pronged strategy.
