New York will invest $ 500 million to protect Manhattan from flooding due to climate change. The municipality said Thursday that this money would fund four projects to protect areas at risk.
The tip of Manhattan was hit hard during Hurricane Sandy in October 2012. According to a study by the New York City Economic Development Group (NYCEDC), 37% of neighborhood buildings are in danger.
to be flooded in 2050.
Walls and inflatable dams
Projects include an inflatable and mobile dam (Tiger Dam), a permanent protective wall located south of Battery Park City (at the extreme south-west of Manhattan) and the elevation of the gardens located at the tip to form a natural barrier against water.
"The challenge we face is unprecedented," said Jainey Bavishi, municipal leader for prevention and risk management. "It's a threat to our very existence, as Hurricane Sandy has so dramatically shown. "
Ten billion to protect Manhattan
The catastrophe of 2012 pushed New York to invest heavily in the prevention of flood risks. Several projects have already been launched, and some already completed. In Staten Island and Far Rockaway, more than 15 km of dunes have been installed to protect the coastline. And in mid-February, $ 615 million in funding was allocated for a proposed 7-mile dike project on Staten Island.
The envelope needed to effectively protect the south of Manhattan is estimated at a total of ten billion dollars, said Thursday Bill de Blasio, the mayor of New York. A substantial portion of this budget is yet to be completed, presumably with the support of federal funds.
