FEMA COASTAL EROSION

Coastal erosion is a natural process, but new mapping projections by FEMA indicate its pace is likely to accelerate with sea level rise as storms are able to attack higher and higher land elevations. Using the map below, navigate around the Islands to explore:

• FEMA Coastal Hazard Erosion Area (2050 high scenario)

• Historical Shoreline: 1890s

• Historical Shoreline: 1970s

• Historical Shoreline: 1980s

• Toggle on/off: Structures / Roads / Parcels
