How to Check Your Property's Flood Risk (and What to Do About It)

FEMA maps show one slice of risk. Climate change is expanding floodplains faster than maps update. A practical guide to assessing and reducing your exposure.

Sources to check

FEMA Flood Map Service Center, First Street Foundation Risk Factor, local floodplain manager, and the property's elevation vs Base Flood Elevation (BFE).

Mitigations that pay back

Backflow valves ($200–$1000): protect against sewer backups. Sump pump with battery backup: essential for basements. Elevating utilities: $1,500–$5,000, huge insurance savings.

Frequently asked questions

Is flood insurance required?
In FEMA Special Flood Hazard Areas (100-year floodplain), yes if you have a federally-backed mortgage. Otherwise it's optional but often wise.
