Hudson Valley communities can plan for the new normal: more frequent and intense flooding, heat and drought
The projections include air temperature, precipitation, heat wave, sea level rise and flood projections from now through year 2100, in the Hudson River region. The projections are taken from Responding to Climate Change in New York State CimAID Report written in 2011 and updated in 2014. New York State officially adopted sea-level rise projections in 2017 for consideration in future planning, permitting and funding programs. You can download a PDF version of these projections and our Climate Summary for Communities to learn more about climate hazards, risks and opportunities Hudson Valley municipalities face.
The report delineates climate projections by region. This fact sheet includes the two Hudson Valley regions: Region 2 (west of the Hudson River) and Region 5 (east of the Hudson River and the Mohawk River region). Region 2 covers Delaware, Greene, Orange, Schoharie, Sullivan, Rockland, and Ulster counties, and Region 5 covers Albany, Columbia, Dutchess, Fulton, Herkimer, Madison, Montgomery, Oneida, Putnam, Rensselaer, Saratoga, Schenectady, Washington, and Westchester counties.
Please note that the federally-designated “100-year” or 1% floodplain is the area that statistically has a 1% chance of flooding each year, based on historical data. Compounded over a 30-year period, this storm has over a 25%, or one in four chance of happening, so using the term “100-year” storm is misleading and gives a false sense of security.
