Great Cities Innovate to Adapt to Possible Global Warming Floods

(p. C3) Spurred by long histories of disastrous storms, the urban engineers of Venice, Tokyo and the Netherlands have been among the pioneers of modern flood control, building storm surge barriers and sea walls on the scale of the pyramids. Such structures could well be models for New York City in the wake of superstorm Sandy.
The cities most experienced in building bulwarks against flood tides and storm surges are at a turning point, however, in their struggle for control of nature. The land upon which they are built continues to sink, population grows and the seas around them rise. As city planners reach the limits of conventional flood control measures, they are experimenting with ways to re-engineer low-lying urban waterfronts.
In Rotterdam, architects are building houses that float on floods. Beneath Tokyo, engineers have tunneled to create miles of emergency floodwater reservoirs. And in St. Petersburg, where storm tides have flooded the city about once a year since its founding in 1703, engineers last year completed a storm-surge barrier more than 15 miles long.
