Another Day, Another FEMA Flood Map Refresh

## Summary

FEMA is updating flood risk maps for certain communities based on new science, changing flood zones and water levels. If you live or own property in these areas, your flood insurance rules might change, possibly affecting costs. You’ve got 90 days after local notice to ask for a review before changes become final, so stay alert and check the updated maps online!

## Abstract

This notice lists communities where the addition or modification of Base Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, or the regulatory floodway (hereinafter referred to as flood hazard determinations), as shown on the Flood Insurance Rate Maps (FIRMs), and where applicable, in the supporting Flood Insurance Study (FIS) reports, prepared by the Federal Emergency Management Agency (FEMA) for each community, is appropriate because of new scientific or technical data. The FIRM, and where applicable, portions of the FIS report, have been revised to reflect these flood hazard determinations through issuance of a Letter of Map Revision (LOMR), in accordance with Federal Regulations. The current effective community number is shown in the table below and must be used for all new policies and renewals.

- 90-day window to request reconsideration: benefit, medium. After the second publication of local notice, any person has 90 days to ask the community to request that FEMA reconsider the revised flood hazard determinations. The flood hazard determination information may change during that 90-day period.

FEMA says the Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report form the basis of the floodplain management measures that a community must adopt or show as in effect to qualify or remain in the National Flood Insurance Program (NFIP). These determinations reflect the minimum re…
- Revised maps available online and locally: benefit, low. Revised flood hazard information for each listed community is available online at the FEMA Map Service Center (https://msc.fema.gov) and at the local community map repository address shown in the table. The current effective FIRM and FIS report are also accessible online for comparison.
