The Elevation Certificate is an important administrative tool of the National Flood Insurance Program (NFIP). It is to be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, and to support a request for a Letter of Map Amendment (LOMA) or Letter of Map Revision based on fill (LOMR-F). InSite professionals utilize our current vertical control network with ties to the most current geodetic benchmarks and GPS technology to ensure accuracy of all elevation certificates. All certificates are always up to date using the most current Effective and Preliminary FEMA map products.
