The National Geodetic Survey (NGS) has determined that it was necessary to readjust the national vertical control network. The current reference is in the National Geodetic Vertical Datum of 1929 (NGVD 29). The vast majority of products of the Federal Emergency Management Agency, National Flood Insurance Program (NFIIP), which is administered by the Federal Insurance Administration (FIA), are currently referenced to NGVD 29 for vertical control data (ground, structure, and flood elevations). To remain in compliance with the national standard, FIA will be converting its products to the new national datum, as mandated by Congress the North American Vertical Datum of 1988 (NAVD 88). This conversion will necessarily take place in a gradual process driven by the opportunity to republish our Flood Insurance Studies (FISs) and Flood Insurance Rate Maps ( FIRMs ) for other substantive reasons.
