Move coastal towns?

A plan by the Louisiana Recovery Authority would move coastal towns 20 miles inland. It's hard to imagine most of the population cooperating without some incentive. Better housing, perhaps? Better roads? What would induce people to move?

Now Louisiana planners are proposing an idea that would have been unimaginable here a few months ago: moving an entire string of seaside towns and villages - and the 4,000 longtime residents who live in them - 15 or 20 miles inland to higher and presumably safer ground. "If we could get 100 percent participation, which admittedly is extraordinarily difficult, if possible at all, we could conceivably take the entire population of Cameron Parish largely out of harm's way for future events," said Drew Sachs, a consultant to the Louisiana Recovery Authority. He has been asked to develop bold suggestions for rebuilding the state's coastal region in the wake of Hurricanes Katrina and Rita.
