FIS & DFIRM Production

What is NFIP Program, FIS and FIRM?

In 1968, the U.S. Congress created the National Flood Insurance Program (NFIP) in response to the rising cost of taxpayer funded disaster relief for flood victims and the increasing amount of damage caused by floods.  The Federal Emergency Management Agency (FEMA) under Department of Homeland Security manages the NFIP, and oversees the floodplain management and mapping components of the Program. FEMA and its partners develop and provide Flood Insurance Study (FIS) and Flood Insurance Rate Maps (FIRMs) in support of FEMA.  FEMA has undertaken a comprehensive effort called Map Modernization (Map Mod) to transform flood maps into a more reliable, easier-to-use, and readily available product. Updated, digital flood maps will become the platform for identifying multiple hazards.

Since 1978, the LJA team of experts has been conducting flood insurance studies for FEMA performing thousands of miles of detail and approximate riverine and coastal studies for many counties and hundreds of communities. We offer comprehensive services from initiation of a study all the way to effective which includes:

  • Scoping
  • Field survey & reconnaissance
  • Levee investigation for compliance
  • Development of digital terrain & LiDAR topographic mapping
  • Flood hazard engineering & mapping
  • DFIRM production
  • Post-preliminary processing

Why to use FIRMs?

FIRMs are used for various purposes by different individuals. Private citizens, insurance agencies, and brokers use the FIRM to locate properties and buildings in flood insurance risk areas. Community officials use the FIRM to administer floodplain management regulations and to mitigate flood damage. Lending institutions and federal agencies use the FIRM to locate properties and buildings in relation to mapped flood hazards, and to determine whether flood insurance is required when making loans or providing grants following a disaster for the purchase or construction of a building. The map associated with a property may be found using FEMA’s Map search. The FEMA’s tutorial on "How to Read a Flood Insurance Rate Map (FIRM) Tutorial" is a helpful guide.
