FEMA Map Change Information and Public Meetings

flood-insurance-mapThe Federal Emergency Management Agency (FEMA) has completed a multi-year project to re-examine Fairfax County’s flood zones and produce detailed digital flood hazard maps. In some cases, the existing flood zone boundaries have been modified. The preliminary updated Flood Insurance Rate Maps (FIRMs), which reflect the flood risk based on the latest data, have been released for public review. As a result, property owners throughout the County will have up-to-date, internet-accessible information about flood risk to their properties.

Status Update: April 2024

FEMA informed the County that they will deliver a revised preliminary FIRM with a 30-day comment period in April 2024. FEMA has not committed to a date for the Letter of Final Determination (LFD), but the County expects to receive the LFD sometime in summer 2024. The County will adopt the revised FIRM within six months of receiving the LFD.

Preliminary maps may be viewed online through the FEMA Map Service Center and FEMA’s Flood Map Changes Viewer. Changes from the current maps may be viewed online through the FEMA Region III Changes Since Last FIRM (CSLF) viewer.

The County notified the owners of all structures where the flood risk will change (either increase or decrease) based on the preliminary FIRMs. The County held a series of virtual public meetings (via Zoom) to provide more information on the proposed changes and respond to questions from residents. The meetings were grouped by designated county watersheds. If you are unsure which watershed your property is in, please see Find Your Watershed to find your location. Registration was required to attend the public meetings. Residents were encouraged to register for the meeting corresponding to the watershed for the property of concern. Each meeting lasted 1.5 hours, with a 45- minute presentation followed by 45 minutes Q&A.

More Information

Please note the updated maps are still in preliminary stage, and may change when the final maps are issued. If the structure on your property is in the Special Flood Hazard Area (SFHA) shown on the final FIRMs and if it has a federally backed mortgage, you will be subject to mandatory flood insurance purchase requirements.

FEMA initiated their appeal process on April 22, 2022. The County evaluated all comments and appeals that were received using existing information, and conducted additional field investigations and surveys. Where warranted, additional analyses were completed to provide supporting technical information for appeals. All valid appeals were compiled and submitted to FEMA on July 22, 2022. The appeal period is now closed.

FEMA is currently in the process of reviewing the appeals and comments submitted on July 22, 2022, and additional data submitted on February 2, 2023. FEMA informed the County that they will deliver a revised preliminary FIRM with a 30-day comment period in April 2024. FEMA has not committed to a date for the Letter of Final Determination (LFD), but the County expects to receive the LFD sometime in summer 2024. The County will adopt the revised FIRM within six months of receiving the LFD.
