Flood map for Boston, Massachusetts

Boston flood map and elevation view

Use this Boston, Massachusetts flood map to inspect Boston Harbor, the Charles River basin, and low waterfront districts around the urban core. The page opens directly on Boston instead of making you pan from the national view.

What you can do

• Open a Boston-centered map instead of manually panning across the U.S.
• Compare elevation and flood scenarios around Boston Harbor, the Charles River basin, and low waterfront districts 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 Boston scenario you want to share.

How to use it

1. Start with the default Boston 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

Boston's coastline, filled land, and river edges make city-scale elevation context useful before drilling down to a block or parcel. FloodMap USA is a screening tool for exploration and comparison, not a substitute for surveys, FEMA products, insurance decisions, or emergency instructions.
