Flood Risk Awareness - Community Flood Map Visualization Project

An increasing percentage of Delaware’s coastal population will be threatened by future flooding due to storm events and rising sea levels. Map visualization tools provide one of the best ways of representing and communicating flood risk and vulnerabilities to individuals and communities.

Community flood mapThis collaborative project by Delaware Sea Grant, the U. S. Geological Survey, and Delaware Department of Natural Resources and Environmental Control (DNREC) uses new mapping technology to create flood visualization maps for various neighborhoods and communities. These community flood risk awareness map products have been created using the best available elevation data in combination with the latest Federal Emergency Management Agency (FEMA) flood mapping products, as well as high water elevations associated with historic storm events.


The flood risk awareness maps provide critical flood and coastal hazard information that will be useful education and disaster preparedness tools for residents, property owners, and community decision-makers. The ability to visualize the potential depth and extent of flood impacts provides an improved understanding of impacts and consequences to future flood risk.
