The following revisions were made in June 2013: Additional information was added on pages 130, 159, 164, 168, 192, 324, and 325 to provide further information about the sea level rise and storm surge analyses. In addition, the exposure statistics presented in Tables 3, 4, 20, 25, 47, 54, and 55 and accompanying text were revised to reflect refined GIS information developed under Task 3.
