New Jersey and New York Coastal Flood Study

FEMA Region II has initiated a coastal flood study to produce updated Flood Insurance Rate Maps (FIRMs) for communities in coastal New Jersey and New York, including New York City. The FIRM, which shows flood hazards for communities participating in the National Flood Insurance Program, is used to determine flood insurance rates and requirements and where floodplain development regulations apply.

The new coastal flood study includes an updated flood hazard analysis, with new storm surge and overland wave modeling. New, detailed topographic information has also been used to map the coastal flood hazards.

As the results of the coastal flood study are completed and mapped, the preliminary FIRMs for each affected community are being distributed and made available online through this website. Learn more about what happens next in the mapping process.
