Maps from a New EPA Study on Sea Level Rise and the Mid-Atlantic Coast
Elevation maps with better data
A multi-year project by the US Environmental Protection Agency (Titus and Wang 2008) (PDF 44pp, 2.2MB) created maps to illustrate vulnerability to sea level rise, using existing data. The maps show elevations relative to spring high water, the average tide during new and full moons. Although the accuracy of the data varies, the maps on this page all have faily good data. Maryland and North Carolina provided LIDAR, Philadelphia and Washington, DC provided elevation data sufficient for 2-ft contours, and the Corps of Engineers provided spot elevation data for coastal New Jersey.
These maps are in jpg files designed for printing at 300 dots per inch on 8-1/2 X 11 inch paper. If you simply click on the links below and try to read them on your computer screen, some of them may look strange, depending on your internet browser. If so, please save the jpg map onto your computer's hard drive and then open the file with the program you normally use to read jpg files.
