Flood map for Charleston, South Carolina

Charleston flood map and elevation view

Use this Charleston, South Carolina flood map to inspect Charleston Harbor, tidal creeks, and the low-lying peninsula street grid. The page opens directly on Charleston instead of making you pan from the national view.

What you can do

• Open a Charleston-centered map instead of manually panning across the U.S.
• Compare elevation and flood scenarios around Charleston Harbor, tidal creeks, and the low-lying peninsula street grid.
• Start with a 3.0m flood setup, then adjust the slider for milder or more extreme water levels.
• Copy a permalink for the exact Charleston scenario you want to share.

How to use it

1. Start with the default Charleston map view and pan toward the shoreline, river, or neighborhood you care about.
2. Use flood mode for scenario testing, or switch to elevation mode to inspect terrain and relative height differences.
3. 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

Charleston combines harbor exposure with marshy low ground, so flood screening benefits from a city-specific starting view. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
