Increased Flood Risk in New York City

Increased Flood Risk in New York City

The light blue area above depicts today’s FEMA 100-year flood zone for the city (the area of the city that is expected to be flooded once every 100 years). With rising sea levels, a 100-year flood at the end of this century (not mapped here) is projected to inundate a far larger area of New York City, especially under the higher emissions scenario.1 Critical transportation infrastructure located in the Battery area of lower Manhattan could be flooded far more frequently unless protected. The increased likelihood of flooding is causing planners to look into building storm-surge barriers in New York Harbor to protect downtown New York City. 2,3,4  Image Reference: Kirshen et al.5; Image Source: Frumhoff et al.2
