Use FEMA Flood Map Service Center to locate the mapping available for the property flood-map review, then confirm the map owner, covered area, study or effective date, and hazard layer. Follow the responsible local authority when the result affects a property decision.
For flood zone lookup, a color or zone is useful only with the property location, hazard type, scenario, map owner, and study or effective date. When FEMA Flood Map Service Center is a national viewer or catalogue, follow it to the current local map before making a property decision.
Find the map owner for flood zone lookup
Use FEMA Flood Map Service Center for the property flood-map review, then identify the map owner, covered hazard, effective or study date, and purpose of the layer shown.
Use the exact parcel and map date
For the property flood-map review, keep the exact address, parcel or coordinates, community or panel number, and the map date visible while comparing layers.
- Exact property address
- Parcel or coordinates
- Map owner or panel
- Effective or study date
Use FEMA’s official flood map tools for U.S. properties, record the zone and map panel, then ask the lender, insurer, and local floodplain office whether newer local information affects the property.
Read the hazard layer in its stated scenario
- Locate the property and confirm the parcel or map pin before reading the colored hazard area.
- In FEMA Flood Map Service Center, identify whether the layer is regulatory, planning, long-term risk, drainage, insurance, or emergency information.
- Before relying on the property flood-map review, record the zone or scenario, panel or study name, effective date, and map owner.
- To complete the property flood-map review, after the first FEMA Flood Map Service Center result, open amendments, map-change documents, local studies, and current warnings separately when they answer different questions.
- Save the authority, map title, date, layer, and property location.
Check coverage, effective date, and local authority together
To complete the property flood-map review, the result is meaningful only when the property, hazard type, scenario, map purpose, and date all match the decision being made.
| Map detail | Why it changes the answer |
|---|---|
| hazard or flood zone | For the property flood-map review, match the property, parcel, or coordinates |
| map owner | In the property flood-map review, identify the mapped hazard, scenario, and source owner |
| effective or study date | Before relying on the property flood-map review, use the effective or study date when comparing maps |
| local study or map-change record | Keep the panel, study, layer, and local-authority link with the property flood-map review |
Use flood zone lookup as mapped evidence for its stated hazard, date, and purpose, not as a promise that flooding will or will not occur or as a final insurance quotation.
If the property is outside the visible study
Check the local floodplain, planning, drainage, emergency-management, or water authority when the national map has no detailed layer.
For the property flood-map review, ask the map owner which current study applies; absence from one viewer is not evidence that the property has no flood risk.
