Maps and Reports on Sea Level Rise
Click on thumbnail for full size image.
The maps that follow in this section were produced in conjunction with the report, "Maps of Lands Vulnerable to Sea Level Rise: Modeled Elevations along the U.S. Atlantic and Gulf Coasts," which was originally published in Climate Research (2001).
The maps illustrate lands close to sea level along the Atlantic and Gulf coasts. The maps are presented in a thumbnail format; click the thumbnails for a full screen (html) view or follow the accompanying links for high-resolution, full-page (pdf) color and black & white versions of the map.

EPA is currently developing two types of maps: elevation maps and sea level rise planning maps. These maps are being developed for states along the East Coast of the U.S. and will become available to the public as they are completed.
The maps will be provided in two separate formats: elevations relative to National Geodetic Vertical Datum (also used by topographic maps) and elevations relative to mean spring high water.
EPA is also creating maps that depict - at the county level - the land likely to be protected from rising sea level and the land likely to be inundated. EPA is developing these maps both to improve impact assessments, and to help coastal decision makers plan for sea level rise. EPA is working with county planners in coastal states to make first-cut assessments of the areas likely to be protected under existing policies. Those maps may be a starting point that enables communities to consider whether or not they are satisfied with the expected long-term results of current policies; and the maps will be adjusted as necessary. Once complete, they can serve as a guide to ensure that infrastructure, homes, and erosion-control activities are generally consistent with the long-term response to sea level rise.
