FEMA P-348, Protecting Building Utility Systems From Flood Damage (2017)

The overall objective of this publication is to assist in the construction of buildings with building utility systems that are designed and built so that the buildings can be re-occupied and fully operational as soon as electricity and sewer and water are restored to the neighborhood.

This publication illustrates the design and construction of utility systems that comply with the National Flood Insurance Program (NFIP) requirements for construction of new residential and non-residential structures in flood-prone areas. It is also useful when evaluating structures that will undergo Substantial Improvement, guiding users to meet floodplain management regulations and building code requirements. Even if compliance is not required, many building owners may find that applying mitigation measures described in this publication will not only reduce future flood damage, but also facilitate recovery after flooding.
