Application processes that are required to change FEMA's floodplain maps.

A Letter of Map Change (LOMC) is a letter that reflects an official revision to an effective Flood Insurance Rate Map (FIRM). FEMA issues LOMCs in place of the physical revision and republication of the effective FIRM.

Online LOMC Application

  • The Online LOMC Application is an internet-based tool that allows applicants to easily request a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR) to a flood map.
  • It is a convenient way for applicants to upload all information and supporting documentation and check the status of their application online.
  • Users can submit LOMC requests and pay any associated fees, through this tool instead of filing the MT-EZ, MT-1 or MT-2 paper forms submitted through the mail.
