FEMA Proposes Updated Flood Maps for Local Communities

## Summary

FEMA is updating flood risk maps for several communities, which could change flood zones and insurance rules. If you live or own property in these areas, these changes might affect your flood insurance costs and building rules. You have until September 9, 2026, to review and comment on the proposed updates before they 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 purpose of this notice is to seek general information and comment regarding the preliminary FIRM, and where applicable, the FIS report that the Federal Emergency Management Agency (FEMA) has provided to the affected communities. 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).
