Engineers, Surveyors & Architects

Main Content

Engineers, surveyors and architects (those employed by private firms and those employed by federal, state and local agencies) 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.

Online Letter of Map Change (LOMC)

Online Letters 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. 

Community Preliminary Flood Hazard Data

FEMA has launched a new way to view your community’s preliminary flood hazard data: over the web and in one convenient location! Preliminary flood hazard data provide an early look at your home or community’s risk to flood hazards. There are many benefits to viewing your community’s data before it becomes effective. For more information, visit the Preliminary Flood Hazard Data webpage.

FEMA Engineering Library

To obtain archival, technical and administrative support data, please visit the Engineering Library.

LOMC Clearinghouse

FEMA’s LOMC Clearinghouse  centralizes the administrative functions associated with processing MT-EZ, MT-1 and MT-2 requests. Specific activities include creation of LOMC case files, upload and scanning of data, processing of associated fees and distribution to the appropriate location for processing.

When submitting paper applications, requestors should mail their applications and supporting data to:

LOMC Clearinghouse847 South Pickett Street,Alexandria, VA 22304-4605Attn: LOMC Manager

 

For more information about the LOMC Clearinghouse, please contact the FEMA Map Information eXchange.
