This report provides an updated set of sea level rise projections that incorporate the latest science and community-scale projections. The new projections can be applied to risk management and planning processes, and are recommend for communities performing coastal impacts assessments within the state of Washington.
An interactive map based on the report shows relative sea level rise (RSLR) projections for 171 sites along Washington’s coast. The projections for each site are provided as a downloadable excel spreadsheet which contains three worksheets: (1) an overview, (2) RSLR projections for a low greenhouse gas scenario (RCP 4.5), and (3) RSLR projections for a high greenhouse gas scenario (RCP 8.5).
