Think Sandy was just a 100-year storm that devastated New York City? Imagine one just as bad, or worse, every three years.
Prominent planners and builders say now is the time to think big to shield the city’s core: a 5-mile barrier blocking the entryway to New York Harbor, an archipelago of man-made islets guarding the tip of Manhattan, or something like CDM Smith engineer Larry Murphy’s 1,700-foot barrier – complete with locks for passing boats and a walkway for pedestrians – at the mouth of the Arthur Kill waterway between the borough of Staten Island and New Jersey.
Act now, before the next deluge, and they say it could even save money in the long run.
These strategies aren’t just pipe dreams. Not only do these technologies already exist, some of the concepts have been around for decades and have been deployed successfully in other countries and U.S. cities.
So if the science and engineering are sound, the long-term cost would actually be a savings, and the frequency and severity of more killer floods is inevitable, what’s the holdup?
Like the argument in towns across America when citizens want a traffic signal installed at a dangerous intersection, Sandy’s 43
