Houston flood map and elevation view
Use this Houston, Texas flood map to inspect Buffalo Bayou, ship-channel corridors, and flat low-lying neighborhoods around the urban core. The page opens directly on Houston instead of making you pan from the national view.
What you can do
Open a Houston-centered map instead of manually panning across the U.S.
Compare elevation and flood scenarios around Buffalo Bayou, ship-channel corridors, and flat low-lying neighborhoods around the urban core.
Start with a 3.0m flood setup, then adjust the slider for milder or more extreme water levels.
Copy a permalink for the exact Houston scenario you want to share.
How to use it
Start with the default Houston map view and pan toward the shoreline, river, or neighborhood you care about.
Use flood mode for scenario testing, or switch to elevation mode to inspect terrain and relative height differences.
Click a specific point on the map for a location-based risk sample, then copy the permalink if you want the same view later.
Model notes
Houston is not just a coastal story; bayous and flat terrain across the metro make localized elevation checks useful well inland. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
