New York flood maps are determined by the Federal Emergency Management Agency, better known as FEMA. FEMA Flood Insurance Rate Maps (FIRMs) are determined by mapping the topography of NYC as well as the types of storm strengths that have historically hit NYC as its mentioned in NYC sea level rise map. Areas are then rated a high risk for flooding and waves, a high risk just for flooding, moderate risk or no risk. These zones, however, may be in flux. FEMA has not significantly updated its sea level rise maps since 1983 and is currently working on new FIRMs for NYC, expected to be released next year.
As sea level rises, urban areas near the coast like NYC will undergo more frequent and intense episodic flooding following major storms, as well as permanent inundation of some low-lying areas as you can see in NYC sea level rise map. Accelerated sea level rise and exacerbated coastal flooding are issues of critical concern for NYC and its broader metropolitan region. The sea level off NYC coast is up to 9 inches higher than it was in 1950.
