New York’s Mayor Bill de Blasio will extend the coastline between Brooklyn Bridge and the Battery into the East River as part of a plan to protect Lower Manhattan from the projected sea-level rises caused by climate change.
The plan, set out by New York City Economic Development Corporation (NYCEDC), consists in building a 150-metre extension, creating a new piece of land with high points lying about six meters above current sea levels.
The project will cost around $500 million.
“We not only have to reduce emissions to prevent the most cataclysmic potential effects of global warming, we have to prepare for the ones that are already inevitable. Our actions will protect Lower Manhattan into the next century,” the mayor said in a statement.
The city's study expected that 37% of Lower Manhattan residents and 50% of properties will be at risk from storm surge by the 2050s. By 2100, rising sea levels would expose 20% of the lower borough to marine flooding.
