Flood map for any U.S. city or ZIP
FloodMap USA is a fast screening tool for exploring elevation and water exposure across the United States. Search a location, inspect terrain, switch to flood mode, and share the exact scenario you are looking at.
What you can do
Jump straight to a city or ZIP code instead of manually panning.
Compare elevation and flood-risk views at the same location.
Test scenarios from high tide through extreme storm surge.
Copy a permalink with the current center, zoom, view mode, and water level.
How to use it
Search for a U.S. city or ZIP code, or pan to the area you care about.
Use elevation mode for terrain context, then switch to flood mode to test a scenario.
Click a specific point on the map for a location-based risk sample and share the permalink if you want the same view later.
Model notes
This is a rapid relative-visibility tool built from elevation and map data. It is useful for exploration, communication, and scenario comparison, but it is not a substitute for parcel surveys, FEMA products, insurance decisions, or emergency instructions.
