View a searchable interactive map of sea level rise & flood risk areas.

Surging Seas utilizes lidar supplied by NOAA and uses as its inundation model a modified bathtub approach, modeling hydrologic connectivity and locally adjusted Mean Higher High Water levels

Water level means feet above the local high tide line (MHHW), any year, through combinations of sea level rise, tide and storm surge. Sea level has been rising, and scientists agree the rise will accelerate, growing its effect on floods.

The water level is set to 5 feet in the example above.
