New York City Mayor Bill de Blasio wants to protect Manhattan from climate change by expanding the island’s southern shore to keep rising seas at bay.

The US$10-billion plan would extend Manhattan Island by as much as 150 metres into the East River by using materials, such as sand or concrete rubble, to build an elevated landscape. Lower Manhattan is a transportation hub for the city and a global financial centre that flooded during Hurricane Sandy in 2012. The project would help to protect the area from what could become daily floods on some streets by 2100, city officials said during a 14 March press conference, citing their assessment of climate-change risks.
