Foundation
NFIP Policy Index
Definition/Description
Without a proper foundation, an elevated building can suffer damage from a flood due to erosion, scour, or settling. The NFIP regulations provide performance standards for anchoring new buildings and foundation and fill placement standards for buildings, for manufactured homes, and in V Zones. However, the NFIP performance standards do not specify how a building''s foundations are to be constructed in A Zones. The national model building codes address building foundations and the proper placement, compaction, and protection of fill.
The use of fill is prohibited for structural support of buildings in V Zones. Pile or column foundations must be used.
