Parts of New York City have already been badly flooded. In sections of Queens, floods are not unusual. In October 2012, Hurricane Sandy flooded much of the southern tip of Manhattan and cut out power for much of the city. The government estimates it will take $46 billion to protect the city from the worsening problem.

According to Bloomberg, “The many projects needed to protect New York against a 100-year storm — a destructive weather event that has a 1% chance of happening in any given year — are expected to cost $46.2 billion without federal funds, plus about $330 million a year in operations and maintenance.” Under the Trump Administration, billions of dollars of possible funding to assist in this problem will be cut. The $42 billion protects $220 billion in land, homes and buildings.

Flood Maps

New York City has already published flood maps that show which areas will be flooded in a 100-year flood. However, these maps may be off considerably given the pace of global warming, rising sea levels, and hurricanes that can move up the coast because of the warming of the Atlantic Ocean.

A “New York City Hazard Map” shows parts of the city at risk today. It includes low-lying parts of each borough and an extremely large section of Queens,

The New York City Mayor’s Office of Climate and Environmental Justice reports, “Since 1900, sea level in New York City has risen by about 12 inches and is projected to continue to increase as much as 5.4 feet by 2100, leading to increased frequency and intensity of coastal flooding.” The $42 billion of work has not even begun.
