Digital Flood Insurance Rate Map (DFIRM)

Definition

Digital Flood Insurance Rate Map (DFIRM) — a flood insurance map developed by the Federal Emergency Management Agency (FEMA) for use with Geographic Information Systems (GIS) technology. This product is considered an "intelligent" map, more than just digital drawings. The map is a computer-based analytical tool that can be used for automated analysis and map updates that are not possible with the current paper maps. DFIRM data are now available for many of the highest flood risk areas.

FIRMette

A section of a flood insurance rate map (FIRM) developed by the Federal Emergency Management Agency (FEMA) that can be created online by selecting the desired area from an image of a FIRM. The FIRMette also includes the map title block, north arrow, and scale bar. Like the FIRM, the FIRMette can be used in many aspects of the National Flood Insurance Program (NFIP), including floodplain management, flood insurance, and enrollment of mandatory flood insurance purchase requirements. Online FIRMettes are the simplest way to see a flood map for a specific location.

Flood Coverage

Coverage for damage to property caused by flood. May be available by endorsement to an all risks policy or to a difference-in-conditions (DIC) policy. Normally, the coverage provided is subject to a per occurrence sublimit, an annual aggregate limit, and a separate deductible. Coverage may also be available from the National Flood Insurance Program (NFIP).

Flood Exclusion

A provision found in nearly all property insurance policies (even in all risks policies) eliminating coverage for damage by flood. May also eliminate coverage for other types of water damage, such as seepage and sewer backup. Flood coverage can sometimes be provided by endorsement. If not, a separate flood insurance policy may be available from the National Flood Insurance Program (NFIP).

Flood Insurance Rate Map (FIRM)

The official flood insurance map of a community on which the Federal Emergency Management Agency (FEMA) has indicated both the special flood hazard areas and the risk premium zones for the designated community. It is the most common map that FEMA produces, used by a variety of parties. Insurance agents and insurers use the FIRM to determine the extent of the flood risk faced by properties and buildings. Community officials use the FIRM to administer floodplain management regulations and to mitigate the loss exposure to floods. Lending institutions and federal government entities use the FIRM to locate properties and buildings in relation to mapped flood hazards and to ascertain whether flood insurance is required when making loans or providing grants to rebuild structures following a disaster.

National Flood Insurance Program (NFIP)

A federally funded program established in 1968 to make flood insurance available at a reasonable cost for properties located in participating communities. NFIP flood insurance is available only for direct damage to buildings and contents; there is no time element coverage.
