This web-based tool calculates projected rates of sea level change for any location along the U.S. coast. The tool can be used to assess vulnerability to future sea level change and to compare several published sea level rise scenarios.


  • Produce tables and graphs of projected sea level change
  • Compare sea level rise scenarios and plot curves in feet or meters relative to NAVD88 or LMSL
  • Select closest NOAA tide gauge, input project dates, and define critical thresholds to develop scenarios
