NYS Sea-Level Rise Projections

Intensified flooding and storm surge are an ever-greater threat to New York’s people, infrastructure and economy as sea-level rises. By 2100, sea levels will be 18 to 50 inches higher than they are today along coastlines and estuaries. Now, this vital information will be incorporated into New York development and design plans because of new guidance in the Community Risk and Resiliency Act (CRRA).

On December 31, 2015, the State Department of Environmental Conservation (NYSDEC) established science-based projections for sea-level rise to guide state adaptation decisions. CRRA mandates that climate risk, including sea-level rise be taken into account when assessing certain permits, facility siting, and funding.

The tables below show the NYSDEC’s sea-level rise projections over different time intervals divided into 3 geographic regions, the Mid-Hudson, the New York City/Lower Hudson, and the Long Island regions. The projections come from the 2014 Climate Change in New York State report.

 

Sea-Level Rise Projections

 

Planning now for sea-level rise will reduce the vulnerability of communities living along New York State’s 1,850 miles of tidal shoreline for decades to come.
