FEMA Opens Another Round of Flood Map Comment Season

## Summary

FEMA is updating flood risk maps for several communities, which could change flood zones and base flood levels. If your community is affected, these updates might impact flood insurance rules and costs. You’ve got until August 20, 2025, to check the new maps and share your thoughts before changes become official.

## Abstract

Comments are requested on proposed flood hazard determinations, which may include additions or modifications of any Base Flood Elevation (BFE), base flood depth, Special Flood Hazard Area (SFHA) boundary or zone designation, or regulatory floodway on the Flood Insurance Rate Maps (FIRMs), and where applicable, in the supporting Flood Insurance Study (FIS) reports for the communities listed in the table below.

The FIRM and FIS report are the basis of the floodplain management measures that the community is required either to adopt or to show evidence of having in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP).
