Maps from a New EPA Study on Sea Level Rise and the Mid-Atlantic Coast

!

A multi-year project by the US Environmental Protection Agency (Titus and Wang 2008) created maps to illustrate vulnerability to sea level rise, using existing data.  The public review draft report on sea level rise by the US Climate Change Research Program used the EPA data set to create multi-county maps, which we post here; The maps show elevations relative to spring high water, the average tide during new and full moons. The accuracy of the data varies, so we have also included an index map showing the data sources.

Unlike the state-specific pages on this site, this page links to maps that you can view online (though they may be a bit larger than your screen). If you then click on one of the those maps, you will download a larger jpg file designed for printing at 300 dots per inch on 8-1/2 X 11 inch paper.
