A FEMA Elevation Certificate is a document that provides elevation information to determine flood insurance rates and compliance with a community’s floodplain management program. Elevation Certificates are also used to support requests for changes in the official mapping of flood hazard boundaries.
Rocco V. D’Andrea, Inc. has been providing Elevation Certificates for clients in Connecticut and New York since the inception of the Federal Emergency Management Agency’s (FEMA) Flood Insurance Rate Map (FIRM) program, including the preparation of Letters of Map Amendment (LOMA) and Letters of Map REvision (LOMR).
We prepare our Elevation Certificates incorporating the latest digital FIRM mapping from FEMA, on-site measurements of ground and structural elevations, and photographs. Over the years, we have established a network of accurate elevation benchmarks within our areas of operation that facilitate making the required measurements, referred to the North American Vertical Datum of 1988 (NAVD 88). This is further enhanced by the use of Global Positioning System (GPS) satellites in conjunction with our in-house GPS reference station RVDI (a participant in the National Geodetic Survey CORS program since 2003) and additional GPS reference stations operated and maintained by the Connecticut and New York Departments of Transportation.
