Sea Level Rise Projections 
This project provides an updated set of sea level rise projections that incorporates the latest science, provides community-scale projections, and is designed for direct application to risk management and planning. 
 
Our new projections reflect the latest science on sea level rise and are an improvement over previous assessments. We recommend using these new projections for coastal impacts assessments within the state of Washington.
 
How is relative sea level rise projected to change along Washington’s coastlines? 
The map below links to 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).
