What is a Letter of Map Change (LOMC)?

A Letter of Map Change (LOMC) is a letter which reflects an official change to an effective Flood Insurance Rate Map (FIRM). LOMCS are issued in response to a request of FEMA to revise or amend its effective flood map to remove a property or reflect changed flooding conditions on the effective map.

What is the Online LOMC site?

The Online LOMC web application allows home owners or their designated representatives to easily request a Letter of Map Change (LOMC). Use this site if your property was inadvertently included in a flood zone, or if the addition of fill elevated your property so that it is above the flood zone.
