New Jersey Affordable Housing at Risk: Threats from Coastal Floods and Sea Level Rise

New Jersey's affordable housing stock is identified as the most vulnerable in the United States by number of dwellings at risk of future coastal flooding. By 2050, 6,825 units (3.7% of the state's stock) are projected to be at risk, representing a 316% increase from 2000. Five New Jersey cities—Atlantic City, Hoboken, Camden, Penns Grove, and Salem—rank among the top 20 cities nationwide for the most affordable housing units at risk by 2050.

• New Jersey has the highest number of affordable housing units in the United States currently exposed to a coastal flood risk event in a typical year, totaling 1,640 units, or approximately 1% of its stock.
• By 2050, the number of affordable housing units at risk of coastal flooding in New Jersey is projected to reach 6,825, which is 3.7% of the state's stock and a 316% increase from the number of units at risk in 2000.
• Five New Jersey cities are ranked in the top 20 nationwide for affordable housing units at risk in 2050: Atlantic City (2), Hoboken (4), Camden (7), Penns Grove (16), and Salem (20).
• In Atlantic City and Camden, at least one-third of affordable housing units could experience flood-risk events four or more times per year by 2050.
• Affordable housing is generally more susceptible to flooding because it is often older, of lower quality, and lacks resilience features such as flood-proofing, backflow prevention valves, or off-grid energy.
