Map Change Options

The Preliminary versions of the Digital Flood Insurance Rate Maps (DFIRMs) and associated Flood Insurance Study (FIS) reports for Hancock, Harrison, and Jackson Counties were issued for review by community officials in November 2007 and were made available for review by citizens and other interested parties at local meetings held in December 2007. Although they were prepared according to rigorous technical standards, the Federal Emergency Management Agency (FEMA) recognizes that changes to the DFIRMs and FIS reports may be necessary.

Summaries of the different options available for changing the modernized DFIRMs and reports are provided below. The data and documentation that must be submitted to support each type of map change request are covered in more detail in the Resources that follow.

Summary of Options for Changing the Preliminary Versions of Maps and Reports

Community officials, individual property owners, and other citizens were given the opportunity to submit formal comments regarding the information presented in the Preliminary versions of the DFIRMs and FIS reports during the formal review and comment periods that followed the issuance of the Preliminary versions of the DFIRMs and FIS reports.  These periods, referred to as 90-day appeal periods, began on January 26, 2008, and ended on April 25, 2008. 

During the 90-day appeal periods, some community officials (or other interested parties through those community officials) submitted appeals of the proposed Base Flood Elevations (BFEs) and comments concerning the other flood hazard and risk information shown on the Preliminary versions of the DFIRMs and FIS reports. The Project Team reviewed the data and documentation submitted in support of those appeals and comments and has notified community officials in writing of the resolution, including whether it was appropriate to revise portions of the DFIRMs and FIS reports. To learn more about the appeals and comments submitted, you should contact the floodplain administrator for your community. To obtain telephone numbers for the community floodplain administrators , go to the Community Information page and click on the county in which your community is located.

Summary of Options for Changing Effective Maps and Reports

After the DFIRMs and FIS reports become effective (see Calendar/Schedule page for details on effective dates), community officials (or other interested parties through community officials) may request Map Revisions to request changes to the BFEs, flood hazard boundaries, regulatory floodway boundaries, and other flood hazard and risk information shown on the DFIRMs and related information shown in the FIS reports.  Detailed information on Map Revision processes and procedures, including support data and documentation requirements, is provided in the MT-2 application forms and instructions package that must be submitted with such requests.

After the DFIRMs and FIS reports become effective, individual property owners also may request property-specific changes through the Letter of Map Amendment (LOMA) or Letter of Map Revision Based on Fill (LOMR-F) procedures. Detailed information on LOMA and LOMR-F processes and procedures, including support data and documentation requirements, are provided in the MT-EZ  and MT-1 application forms and instructions packages that must be submitted with LOMA and LOMR-F requests.
