When experts sketch out nightmare hurricane scenarios, a New York strike tends to be high on the list.
Besides shaking skyscrapers, a major hurricane could send the Atlantic Ocean surging into the nation's largest city, flooding Wall Street, subways and densely packed neighborhoods.
As a new hurricane season starts Monday, some scientists and engineers are floating an ambitious solution: Barriers to choke off the surging sea and protect flood-prone areas.
The plan involves deploying giant barriers and gates that would move into place — in some cases rising out of the water — for storms. One proposal calls for a 5-mile-long barrier between New Jersey and Queens.
No one has formally proposed the structures, which would require extensive government reviews and billions of dollars.
But a first-ever conference on the subject this spring drew 100 researchers and engineers, who provided various conceptual designs. City emergency management officials say they're interested in hearing more if details develop.
