Details about the County's Flood Rating 

Thurston County is rated a Class 2 in FEMA's National Flood Insurance (NFIP) Community Rating System because the County's flood planning, flood reduction and flood education efforts exceed FEMA's minimum requirements. This rating provides a 40 percent discount on NFIP premiums for property in special flood hazard areas, and 10 percent discount for properties outside those areas in unincorporated parts of Thurston County. The rating was Class 4 until October 2016. Only two other communities in Washington have this rating, Pierce and King counties.
