Through its Risk MAP program, FEMA continually releases new flood maps and data, giving communities nationwide access to helpful, authoritative data that they can use to make decisions about flood risk.
The Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12) as revised with the Homeowner Flood Insurance Affordability Act of 2014 directs FEMA to notify members of Congress when constituents in their district are, and will be, affected by a flood mapping update.
As of June 2014, FEMA began producing a monthly summary document to serve as notification to Congress and provide details of mapping milestones reached in the previous month and an estimated schedule of certain mapping activities anticipated in the next three months. These notices to Congress are available through the FEMA Library:
- Notice to Congress: Monthly Updates on Flood Mapping for 2014
- Notice to Congress Monthly Updates on Flood Mapping for 2015
Know your local flood risk by viewing and downloading your community’s flood risk products from FEMA's Flood Map Service Center (MSC) . Flood risk products are non-regulatory resources that help communities gain a better understanding of flood risk and its potential impacts that FEMA provides in addition to the regulatory Flood Insurance Rate Map and Flood Insurance Study products. Flood risk products may include: Flood Risk Map (FRM), Flood Risk Report (FRR) and Flood Risk Database (FRD).

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 now use the Online LOMC, an internet-based tool, to easily request map amendments or revisons: LOMA, CLOMA, LOMR-F, CLOMR-F, LOMR or CLOMR. This new 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 Online LOMC application.
