What Is A LOMA?

Are you curious to know what is a LOMA? You have come to the right place as I am going to tell you everything about a LOMA in a very simple explanation. Without further discussion let’s begin to know what is a LOMA?

In the complex world of floodplain management and real estate, a term often encountered is “LOMA,” which stands for Letter of Map Amendment. While this term may seem obscure, it holds significant importance for property owners and communities in flood-prone areas. In this blog, we will demystify LOMAs, explore their purpose, and discuss why they matter in the realm of floodplain management.

What Is A LOMA?

A Letter of Map Amendment, or LOMA, is an official document issued by the Federal Emergency Management Agency (FEMA) in the United States. FEMA is responsible for managing and updating flood hazard maps, which delineate areas prone to flooding. LOMAs serve as a means to amend or revise these flood maps for specific properties or structures.

The Purpose Of A LOMA

The primary purpose of a LOMA is to officially remove a property or structure from the Special Flood Hazard Area (SFHA) as designated on FEMA’s flood maps. SFHAs are areas at risk of flooding during a 100-year flood event, which has a 1% chance of occurring in any given year. Being in an SFHA typically triggers mandatory flood insurance requirements for property owners.

Property Owners Can Seek A LOMA For Several Reasons:

  1. Accurate Mapping: If a property owner believes that their property has been inaccurately mapped in the SFHA, they can apply for a LOMA to correct this error.
  2. Elevation Above Base Flood Level: A LOMA can be requested if a property is situated at an elevation above the Base Flood Elevation (BFE), which is the expected height of floodwaters during a 100-year flood event.
  3. Flood Protection Measures: If a property has been equipped with flood protection measures, such as levees or berms, that effectively mitigate the risk of flooding, a LOMA can recognize these measures and exempt the property from the SFHA.
  4. Change in Topography: Changes in the topography or grading of the land can impact a property’s flood risk. A LOMA can reflect these changes.

The LOMA Process

Obtaining a LOMA involves a formal application process. Here are the general steps:

  1. Property Assessment: Property owners assess their property’s elevation relative to the BFE and gather any supporting documentation, including elevation certificates or surveys.
  2. FEMA Application: Property owners submit a LOMA application to FEMA, along with the required documentation. The application can be submitted online through FEMA’s Mapping and Insurance eXchange (FMIX) system.
  3. Review and Approval: FEMA reviews the application, including the supporting documentation, to determine whether the property qualifies for an amendment. If approved, FEMA issues a LOMA.
  4. Insurance Implications: Once a LOMA is granted, the property is no longer designated as part of the SFHA, and flood insurance requirements are typically lifted. Property owners should inform their insurance provider of the LOMA to adjust or cancel their flood insurance policy accordingly.


In areas prone to flooding, a Letter of Map Amendment (LOMA) can be a valuable tool for property owners seeking to correct inaccuracies in FEMA’s flood hazard maps or to demonstrate that their property is not at risk of flooding. By obtaining a LOMA, property owners can potentially save on flood insurance costs and gain peace of mind knowing that their property is accurately assessed in terms of flood risk. The LOMA process is an essential aspect of responsible floodplain management, helping communities and property owners better understand and address flood hazards.

What Is The Purpose Of LOMA?

A LOMA establishes a property’s location in relation to the Special Flood Hazard Area (SFHA). LOMAs are usually issued because a property has been inadvertently mapped as being in the floodplain, but is actually on natural high ground above the base flood elevation.

Do LOMAs Expire?

The LOMA or LOMR-F is likely to be superseded by new information on the FIRM and will no longer be valid. The LOMA or LOMR-F is likely to be revalidated when the new map panel is published. More information is required to make a determination.
