This June 9, 2001 photo from the Houston Chronicle made available by the Texas Medical Center shows flooding from tropical storm Allison in front of the MD Anderson Cancer Center in Houston. The floods caused a blackout, inundated medical center streets with up to 9 feet of water, and forced evacuations of patients from the district's 6,900 hospital beds. If metropolitan New York is going to defend itself from surges like the one that overwhelmed the region during Superstorm Sandy, decision makers can start by studying how others have fought the threat of fast-rising water.
