will to build a proposed system of giant storm barriers at the mouth of New York
Harbor will likely be very difficult. Even at a cost of up to $27 billion, such
barriers would leave large parts of the region unprotected.
So
government, businesses and property owners will need to consider taking smaller
steps — on land — to minimize the impact of flooding, with or without sea
barriers.
The good news is that many cities have already learned much
about how to limit the damage from floods. Researchers are working on still
other strategies,Using wheel spacer

tunnels from water.
But there's no single cure-all.
"You really
have to go with a series of levels of protection. You can't just buy into one
engineer's dream of building" a 5-mile-long barrier for New York Harbor, said
Phil Bedient, a flood expert at Houston's Rice University whose research was key
to shoring up that city's defenses after it was swamped by Tropical Storm
Allison in 2001. "So you have to pick your spots carefully. And you really can't
protect everything."
Sandy's destruction in the New York area highlights
a host of weaknesses that must be addressed, experts said. But the region's
size, density and geography will complicate the task.

construction. "New York City is unique in the number of people who live there,
the age of the buildings, that it's on islands and it's a hub of U.S.
commerce."
