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.
The Federal Emergency Management Agency's (FEMA) Customer and Data Services (CDS) has launched the Letters of Map Change (LOMC) Clearinghouse, which will centralize 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 Production and Technical Services (PTS) firm for processing.
As a result, there is a new mailing address. Beginning immediately, requestors should mail their applications and supporting data to:
LOMC Clearinghouse
6730 Santa Barbara Court
Elkridge, MD 21075
Attn: LOMC Manager
For more information about the LOMC Clearinghouse, please contact FEMA's Map Assistance Center at
