About enforcing building codes
Adopting and enforcing building codes is an important tool that communities can use to reduce flood risk and prevent future losses. In many communities, flood-related building codes come from the National Flood Insurance Program’s (NFIP) minimum floodplain management standards. These standards include provisions that the elevations of buildings in flood-prone areas be at or above Base Flood Elevation (BFE; the project height of waters in the 1% annual chance flood). They also define certain construction materials or methods to minimize future flood damage. While the NFIP’s minimum standards are useful, FEMA strongly encourages communities to adopt building codes that go beyond the minimum requirements and provides resources to support those efforts.
Many state and local governments have gone beyond federal standards to protect their communities from flooding. For example, many communities in Delaware require the lowest floor of buildings in the 1% annual chance floodplain to be elevated 1 foot or more above BFE. The state has also developed a model drainage code to complement and improve communities’ stormwater management efforts. Enforcing building codes that comply and go beyond federal standards provides individuals and communities with an excellent mechanism to protect themselves from flooding.
