The site shows visualizations of flooding for ten coastal communities in Delaware. Each flood map has an interactive before/after slider tool to display the landward extent of flooding (horizontal) and floodwater depths (vertical) expected to occur during a 100-year flood (or 1 percent annual chance) event.

The maps can help residents, property owners, and community decision makers visualize the potential depth and extent of flood impacts, providing an improved understanding of damage possible from a significant flood or storm in their area.
