Flood map for San Francisco, California

San Francisco flood map and elevation view

Use this San Francisco, California flood map to inspect the Bay shoreline, Mission Creek, and low waterfront zones around downtown and SoMa. The page opens directly on San Francisco instead of making you pan from the national view.

What you can do

• Open a San Francisco-centered map instead of manually panning across the U.S.
• Compare elevation and flood scenarios around the Bay shoreline, Mission Creek, and low waterfront zones around downtown and SoMa.
• Start with a 3.0m flood setup, then adjust the slider for milder or more extreme water levels.
• Copy a permalink for the exact San Francisco scenario you want to share.

How to use it

1. Start with the default San Francisco 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

San Francisco mixes steep terrain with vulnerable waterfront edges, so a city-centered flood view helps separate bluff areas from exposed shoreline. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
