Digital Flood Insurance Rate Maps (DFIRMs)                                                                                  

right arrow  New Digital Flood Insurance Rate Maps (DFIRMs) Now Available

The Federal Emergency Management Agency (FEMA) released newly updated and digitized "draft" flood insurance rate maps for Thurston County in January 2011.  Until the adoption process is complete, the new maps are known as Preliminary DFIRMS.

The original FIRMs dated back to 1972, when the county was first accepted into the National Flood Insurance Program.

The update process resulted in changes to the flood risk zones for some properties. The county is notifying all affected households of the changes by mail, and a meeting was held May 9, 2011 to provide an opportunity for discussion.

The DFIRMs will help local officials and residents identify currently known flood risks. When finalized, the maps will be used for flood insurance, land use planning and development decisions. They will be easier for users to access, and easier for FEMA to update.

right arrow DFIRMs: Definition and Purpose

Flood Insurance Rate Maps (FIRMs) are the official maps on which FEMA has delineated special flood hazard areas and risk zones. They show the location of a property relative to special flood hazard areas, which is one of the factors determining flood insurance rates. More information on FIRMs is available at

FIRMs are used by:

  • Citizens, insurance agents and real estate brokers to locate properties and buildings in flood insurance risk areas.
  • Planning staff and building officials to administer floodplain management regulations and to mitigate flood damage.
  • Lending institutions and federal agencies to locate properties and buildings in relation to mapped flood hazards, and to determine if flood insurance is required when making loans for the purchase or construction of a building or for providing grants following a disaster.

Until recently, these maps have been available in paper form at cities and counties, and online through FEMA. The maps are now digitized, with updated boundaries in some areas. They will be easier for users to access and navigate.

The new maps are a GIS (Geographical Information System) database of flood hazard information which will align with the county’s existing GIS databases for other property and development-related information.

Changes to the maps include:

  • Revised floodplain boundaries based on current topographic data for the County.
  • Revised base flood elevations (BFEs) for a small portion of the Deschutes River.  See map panel 53067C0315E.
  • Revisions were also made to: city limits; road networks (including revised road names); streams and lakes, including names; and building footprints.

The changes may affect mortgage loan requirements and flood insurance rates for those properties in areas proposed for adjustment. Please see the FEMA summary on how map changes can affect flood insurance.
