Visualize Flooding
• Displays potential flooding
• Provides simulations of flooding at local landmarks
• Communicates the spatial uncertainty of mapped sea levels
• Overlays social and economic data onto potential flood scenarios

Impacts of Sea Level Rise
Visualize impacts for 6-foot SLR scenarios overlaid on aerial imagery, street map, and terrain map. Photos of SLR on individual structures will illustrate site-specific impacts.

Communicate Mapping Confidence
Visualize the mapping confidence of inundation area based on uncertainty of elevation data and MHHW tidal surface.

Coastal Flood Frequency
Communicate that today’s flood in tomorrow’s high tide. Use three years of observed water lever data at National Ocean Service Nation Water Level Observation Network (NWLON)
stations to show increased frequency of everyday flooding

Visualize Marsh Impacts
Visualize the impacts of SLR scenarios on marshes using Coastal Change Analysis Program (C-CAP) data.
