Public Invited to Review Flood Maps in City of Fairfax

Release Date Release Number

PHILADELPHIA - FEMA is proposing updates to the Flood Insurance Rate Maps (FIRMs) for the City of Fairfax, Virginia. The community is invited to participate in a 90-day appeal and comment period.

The updated maps were produced in coordination with local, state and FEMA officials. Significant community review of the maps has already taken place, but before the maps become final, community members can identify any corrections or questions about the information provided and submit appeals or comments.

The 90-day appeal period will begin on or around October 6, 2022. Residents, business owners and other community members are encouraged to review the updated maps to learn about local flood risks and potential future flood insurance requirements. Those who are interested in making comments may submit an appeal if they perceive that modeling or data used to create the map is incorrect.

  • An appeal must include technical information, such as hydraulic or hydrologic data, to support the claim.
  • Appeals cannot be based on the effects of proposed projects or projects started after the study is in progress.
  • If property owners see incorrect information that does not change the flood hazard information—such as a missing or misspelled road name in the Special Flood Hazard Area or an incorrect corporate boundary—they can submit a written comment.

The next step in the mapping process is conducting this 90-day appeals period and addressing any comments or appeals that are received. Once they are resolved, FEMA will notify communities of the effective date of the final maps.

Submit appeals and comments by contacting Satoshi Eto, Public Works Program Manager, 703-273-6073 or email The preliminary maps may be viewed online at the FEMA Flood Map Changes Viewer: Changes from the current maps may be viewed online at the Region 3 Changes Since Last FIRM Viewer:
