Within this section, the following references and links will assist homeowners in locating and obtaining copies of their perspective flood maps which are also called Flood Insurance Rate Maps (FIRMs), how to read them, and how to request map changes that may be warranted.
Flood maps 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.

- Did you know that homes in the so-called "100-year" floodplain have a 26% chance of flooding over a 30-year period -- the length of a typical mortgage?
- Did you know that flood insurance is available to all homeowners—even those located outside high-risk areas? Know the Facts.
You may view and order copies of the effective maps and other NFIP products through the Map Service Center. Your local Community Map Repository, usually located in the planning and zoning office, also has copies of flood maps. Please contact the FEMA Map Information eXchange to determine the location of your Community Map Repository.
Know your local flood risk by viewing and downloading your community’s flood risk products from FEMA’s 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 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.
