Mapping
Flood maps help identify areas that may be at risk of flooding. These maps are used by property owners, local officials, insurance agents, lenders, surveyors, and others to understand flood risk and determine what requirements may apply to a property.
The Federal Emergency Management Agency develops Flood Insurance Rate Maps, also called FIRMs, to show areas of high, moderate, low, and undetermined flood risk. These maps are used to support floodplain management, flood insurance rating, local permitting, and development decisions. FEMA flood maps are developed using geographic data, historical flood information, and engineering analysis.
Find a Flood Map
The FEMA Flood Map Service Center is the official public source for flood hazard information produced in support of the National Flood Insurance Program. You can use the Map Service Center to search for an official flood map, view flood hazard data, and access other flood risk products.
Flood Map Changes
Flood maps may change when FEMA updates flood hazard information for a community. The Flood Map Changes Viewer allows users to view flood hazard data at different stages, including current National Flood Hazard Layer data, preliminary map information, and changes since the last Flood Insurance Rate Map.
This information can help local officials, planners, and community partners understand where flood risk may be changing and how those changes may affect properties, development, and mitigation planning.
Tennessee Property Viewer
The Tennessee Property Viewer can help users search for property information and view flood hazard information for many Tennessee counties. The viewer is available for 85 of Tennessee’s 95 counties. If your county is not listed, visit your county’s website or contact your local officials for property information.

- Select the property.
- Turn on the FEMA flood map layer to view flood hazard information.
Contact Your Local Floodplain Administrator
Flood maps are one tool for understanding flood risk, but local requirements are managed by each community. If you have questions about permits, development requirements, elevation certificates, or whether a property is located in a regulated floodplain, contact the floodplain administrator for the community where the property is located.
Need a Map Review?
If you believe a property or structure was incorrectly shown in a flood hazard area, you may be able to request a formal map review through FEMA.
