Jefferson County participates in the National Flood Insurance Program (NFIP), which allows property owners in unincorporated Jefferson County to obtain flood insurance for development within mapped floodplains.  

In 2018, the Federal Emergency Management Agency (FEMA) completed their update of a report entitled Flood Insurance Study for Jefferson County, Washington and Incorporated Areas (FIS), which served as a basis for updated Flood Insurance Rate Maps (FIRMs) for Jefferson County.  In December 2018, FEMA confirmed that the FIS and the FIRMs are final for Jefferson County and stated that the county must begin using these documents on June 7, 2019.

To comply with this requirement,  Jefferson County is in the process of updating the flood damage prevention ordinance (as codified in Chapter 15.15 of the Jefferson County Code).  This update is intended to make the ordinance consistent with FEMA requirements.
