Within this section, the following references and links will assist homeowners in locating and obtaining copies of their perspective floodmaps, how to read them, and how to request map changes that may be warranted.
Floodmaps are the tool the Federal Emergency Management Agency (FEMA) uses to determine the flood risk homeowners face. Prior to the enactment of the National Flood Insurance Program (NFIP), homeowners had no mechanism to protect themselves from the devastation of flooding, and in many parts of the United States, unchecked development in the floodplain was exacerbating the flood risk.

Change my Flood Zone Designation
If a property owner thinks their property has been inadvertently mapped in a Special Flood Hazard Area (SFHA), they may submit a request to FEMA for a Letter of Map Change (LOMC). A SFHA is defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. A LOMC reflects an official revision/amendment to an effective Flood Insurance Rate Map (FIRM). If the LOMC request is granted, property owners may be eligible for lower flood insurance premiums, or the option to not purchase flood insurance.
Applicants can use Online LOMC, an internet-based tool, to easily request a flood map Amendment or Revision. This tool 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 through this tool instead of filing the MT-EZ, MT-1, or MT-2 paper forms via mail.
Get started today using the new Online LOMC application.
