Preliminary DFIRMs
Map Change Options

When FEMA issues a new flood map and associated Flood Insurance Study (FIS) report, there are different options available for changing the updated flood maps and reports. 

Individual property owners and other citizens may submit formal comments on or objections to the information during the formal review and comment periods that follows the issuance of the preliminary Digital Flood Insurance Rate Maps (DFIRMs) and FIS report.  This period is referred to as the 90-day appeal period and will begin in mid-January, 2008. 

The Resources below explain the different options in greater detail and describe the data that must be submitted to support each request. 

Summary of Options

During the 90-day Appeal period, community officials (or other interested parties through community officials) may submit an appeal of the proposed Base Flood Elevations (BFEs) shown on the Preliminary copies of the DFIRMs and FIS reports. 

During the 90-day Appeal period, community officials (or other interested parties through community officials) also may submit a protest concerning flood hazard information other than BFEs shown on the Preliminary copies of the DFIRMs and FIS reports.

After the DFIRMs and FIS reports become effective, community officials (or other interested parties through community officials) may request Map Revisions to request changes to the BFEs, floodplain boundaries, and regulatory floodways shown on the DFIRMs. 

After the DFIRMs and FIS reports become effective, individual property owners may request property-specific changes through the Letter of Map Amendment or Letter of Map Revision Based on Fill procedures.
