Property research / FEMA maps
Read the flood map before you decide.
Search an address in FEMA’s official Map Service Center, then use this guide to make sense of the zone and the map’s effective date.
Open FEMA address search ↗Find the official map.
FEMA’s Map Service Center lets you search by address, place or coordinates and open the effective Flood Insurance Rate Map. A saved FIRMette is a small printable excerpt; keep its panel and effective date with your notes.
Open the effective map
Read the zone at the location and check the legend. Save the panel or FIRMette and its effective date; maps can be revised.
Check what it leaves out
Ask the local floodplain administrator about map amendments, local drainage and the property’s elevation. A zone alone is not a complete property assessment.
For a specific propertyPublic Atlas does not assign flood zones by address. The issuing FEMA map and local floodplain office are the places to verify a location-specific designation. Flooding can occur outside mapped Special Flood Hazard Areas.
What A, AE and X mean.
Mapped 1% annual-chance floodplain
FEMA identifies the base floodplain using approximate methods. A base flood elevation is generally not shown for Zone A.
Mapped 1% annual-chance floodplain with elevations
FEMA’s detailed analysis provides base flood elevations on the map or in the associated study.
Read shaded and unshaded separately
Shaded X commonly marks moderate hazard, including the 0.2% annual-chance floodplain. Unshaded X generally marks minimal mapped hazard. Neither means flooding is impossible.
The “1% annual chance” describes the chance in any single year. It does not mean a flood happens only once every 100 years. A and AE are among FEMA’s Special Flood Hazard Area zones; other zones, including coastal V/VE, also exist.
Before you use the result
Is Zone X flood-free?
No. It describes FEMA’s mapped category, not an absence of flood risk. Drainage, heavy rain and map limitations can still matter.
Does Zone AE give the depth at my house?
No. Its base flood elevation is a water-surface elevation relative to a stated vertical datum. Interpreting it for a building requires an appropriate property elevation and local review.
Can I use an older screenshot?
Use the effective FEMA map and record its date. If a lender, insurer or local authority needs a determination, ask them which documents and map amendments apply.
