Flood map for Seattle, Washington

Seattle flood map and elevation view

Use this Seattle, Washington flood map to inspect Puget Sound, Elliott Bay, and low shoreline areas around downtown and the Duwamish corridor. The page opens directly on Seattle instead of making you pan from the national view.

What you can do

• Open a Seattle-centered map instead of manually panning across the U.S.
• Compare elevation and flood scenarios around Puget Sound, Elliott Bay, and low shoreline areas around downtown and the Duwamish corridor.
• Start with a 3.0m flood setup, then adjust the slider for milder or more extreme water levels.
• Copy a permalink for the exact Seattle scenario you want to share.

How to use it

1. Start with the default Seattle 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

Seattle's hills create sharp elevation shifts near the shore, which makes city-scale screening useful for comparing waterfront and upland areas. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
