FEMA Map Information eXchange (FMIX) Overview


The FMIX provides information to the public about the National Flood Insurance Program (NFIP) rules, regulations, and procedures. Map Specialists respond to inquiries from Federal, State, and local officials and the general public, and inform callers about the following:

  • Requirements necessary to meet NFIP criteria for Letters of Map Change (LOMCs), Physical Map Revisions, appeals, protests, and community compliance;
  • Preliminary and Revised Preliminary Flood Insurance Study reports and Flood Insurance Rate Maps;
  • Requests for technical and administrative support data;
  • LOMC Revalidation Letter and Re-issuance Processes;
  • Map Change and Data Request Processing Fees; and
  • Letters of Determination Review (LODRs).

The FMIX is often the first point of contact between the Federal Emergency Management Agency (FEMA) and various flood map users. The FMIX's goal is to provide the appropriate information to callers to help them understand the technical issues involved in a particular situation. In addition to taking incoming telephone calls, Map Specialists respond to mapping-related e-mail inquiries, and also review and process Letter of Map Amendment (LOMA), Letter of Map Revision Based on Fill (LOMR-F), and LODR requests.

Map Specialists are well versed in the various LOMC processes and can explain the processes to callers with limited familiarity with data requirements such as official land records or certified elevation data. Map Specialists will provide Spanish translation when needed. They also handle map revision inquiries from surveyors, engineers, community officials, lenders, insurance agents, appraisers, and floodplain managers. For more information, you may view or download the FMIX information flyer.

The FMIX is also a good place to obtain FEMA publications or to obtain assistance with finding publications in the FEMA Library. The publications that are most frequently requested include the following: the most recent NFIP regulations; Appeals, Revisions, and Amendments to National Flood Insurance Program Maps: A Guide for Community Officials, and FEMA pamphlets and brochures that address the map amendment and map revision processes.
