New York City is proposing to spend $3 billion on a massive wall to keep out the rising ocean. (See: climate change and sea level rise.) It’s called the “Big U” (see the map below…..it looks like the letter “U”). New York City has the money, and the stature and the motivation.
The article is long, but it gets into what NYC is doing and why, the positives and negatives a giant dike, and the politics (of course).
Excerpt:
Next year, if all goes well, the city will break ground on what’s called the East Side Coastal Resiliency Project, an undulating 10-foot-high steel-and-concrete-reinforced berm that will run about two miles along the riverfront. It’s the first part of a bigger barrier system, known informally as “the Big U,” that someday may loop around the entire bottom of Manhattan, from 42nd Street on the East Side to 57th Street on the West Side. Zarrilli likes to underscore that the barrier will be covered with grass and trees in many places, as well as benches and bike paths – it’s the East Side equivalent of the High Line, the hugely popular elevated train track on the West Side that has been transformed into an urban park. There are plans in the works to build other walls and barriers in the Rockaways and on Staten Island, as well as in Hoboken, New Jersey, across the Hudson River. But this project in Lower Manhattan is the headliner, not just because the city may spend $3 billion or more to construct it, but also because Lower Manhattan is some of the most valuable real estate on the planet – if it can’t be protected, then New York is in deep trouble.
