The U.S. Army Corps of Engineers now considers SLR in many EISs involving ports and coastal waterways. For example, a 2010 EIS
for the Mississippi River Gulf Outlet Ecosystem Restoration Study in Louisiana provides a comprehensive analysis of climate change impacts on SLR. This coastal wetlands restoration plan considers the likely impacts of SLR on wetlands in the Mississippi delta, including submersion, subsidence and shoreline retreat, and discusses mitigation measures which may reduce wetlands loss. It also considers the effect of intensified storm surges, risks to the New Orleans metropolitan area, and the effect of saltwater intrusion on freshwater habitat and drinking water supply. While citing high scientific uncertainty about the degree of SLR, the EIS uses available modeling techniques to produce projections through the end of the century and calls for further study of the issue.
