Letter of Map Changes

If you believe your property was incorrectly shown in a flood zone, or that changes to your land should alter the flood-hazard designation, you can request a formal review through a Letter of Map Change (LOMC). A LOMC asks FEMA to re-evaluate whether your structure or land should be considered part of a “Special Flood Hazard Area.” 

What a LOMC Can Do

Depending on your situation, a LOMC may result in a determination that your property:

  • Is not in a high-flood-risk zone after all (for land/structures on naturally high ground),
  • Has been raised (for instance, by adding fill) and should no longer be treated as high-risk, or
  • Reflects changes in floodplain maps due to updated flood-hazard analysis for larger areas. 

How to Request a LOMC

A homeowner or a licensed Tennessee surveyor or engineer will need to complete one of FEMA’s official forms (MT-EZ, MT-1, or MT-2), depending on the type of change requested. For more information on a LOMC, the necessary forms, and step-by-step guides and tutorial information, visit FEMA's Letter of Map Amendment & Letter of Map Revision-Based on Fill Process webpage.
