Sea-Level Rise Map

Map Notes

The projections and scenarios are based on a 2012 National Research Council report (“Sea-Level rise for the Coasts of California, Oregon, and Washington: Past Present and Future”). Water levels account for the National Tidal Datum Epoch 1983-2001 (NTDE 83-01). The base digital elevation model (DEM) used in the analysis was produced using a 2001 Puget Sound LiDAR Consortium study, which notes a vertical accuracy, or margin of error, of 1 foot (NAVD88). Finally, “breaklines” were not applied; therefore some objects such as piers may not be accurately depicted.
