NEW YORK AFFORDABLE HOUSING AT RISK: Threats from Coastal Floods and Sea Level Rise

New York City is ranked first among U.S. cities for the most affordable housing at risk by 2050, with projected annual risk increasing by 248% to 4,774 units. New York State's affordable housing stock is the second most vulnerable in the nation, with 5,293 units projected to be at risk by 2050, representing a 236% increase from current levels.

• New York City currently has 1,373 affordable housing units threatened by coastal flooding, which is the highest number of any city, though it represents approximately 1% of the city's affordable housing supply.
• By 2050, the number of affordable housing units in New York City expected to be at risk per year will increase by 248% to 4,774 units.
• New York State has the second most vulnerable affordable housing stock in the United States regarding future coastal flooding risk. Currently, 1,574 units (about 1%) are threatened, and this is projected to rise to 5,293 units (1.1% of the state's stock) by 2050, a 236% increase.
• In New York State, 867 affordable housing units could be exposed to four or more flood-risk events per year by 2050.
• Affordable housing is generally more susceptible to flooding than other housing because it is often older, of lower quality, and lacks resilience features such as flood-proofing, backflow prevention valves, and off-grid energy.
