Engineers, surveyors and architects are actively involved in the development of the new and updated flood hazard information presented on National Flood Insurance Program (NFIP) flood hazard maps and related products. This page outlines products, services and publications available to engineers, surveyors and architects including those employed by private firms and those employed by federal, state and local agencies.
Online Letter Of Map Change (LOMC)
The Online Letter of Map Change (LOMC) is an internet-based tool that allows applicants to easily request any type of LOMC. It is a convenient way for applicants to upload all information and supporting documentation and check the status of their application online. Users can submit flood map amendment or revision requests and pay any associated fees through this tool instead of filing the MT-EZ, MT-1, or MT-2 paper forms submitted through the mail.
View And Obtain Flood Mapping And Study Products
- The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the NFIP. The MSC offers an All Product Search option, which allows you to view a range of products available for a community and sort by their regulatory product status (effective, pending, preliminary, and historic).
- 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, toll free at 1-877-FEMA MAP (1-877-336-2627) or email a Map Specialist at FEMAMapSpecialist@riskmapcds.com to determine the location of your Community Map Repository.
- To obtain archival, technical, and administrative support data, please visit the FEMA Engineering Library. Requests for archived data can be submitted via email, mail, or facsimile.

Changing a Map?
- What is the difference between the Online Letters of Map Change (LOMC) and the eLOMA tool?
Online LOMC is an internet-based tool that allow an applicant, including but limited to a professional or property owner, to easily request any type of LOMC. It is a convenient way for applicants to upload all information and supporting documentation and check the status of their application online. Users can submit flood map amendment or revision requests and pay any associated fees through this tool instead of filing the MT-EZ, MT-1, or MT-2 paper forms submitted through the mail.
The eLOMA tool is available for licensed surveyors and engineers to submit LOMA requests that are not considered to be within a coastal zone, alluvial fan, or modified by fill to raise the elevation of the structure.
The required FEMA Flood Mapping Related Forms, including application form packages, community acknowledgement forms, and elevation forms, are available online. When submitting paper applications, requestors should mail their applications and supporting data to:
LOMC Clearinghouse
847 South Pickett Street
Alexandria, VA 22304-4605
Attn: LOMC Manager
