Frequently Asked Questions

What is the statutory authority for the Thurston County Board of County Commissioners to increase from three to five members? 

Pursuant to RCW 36.32.055(1), the board of county commissioners of a non-charter county with a population of three hundred thousand or more, and less than four hundred thousand, may cause a ballot measure proposition to be submitted at a general election of the county authorizing the board of commissioners to be increased to five members.

On June 29, 2022, the Office of Financial Management (OFM) updated Thurston County population estimates to 300,500 based on the 2021 Census data.

How much will this cost the taxpayers? 

  • One-time election costs of $392,000.
  • Ongoing annual staffing costs of $754,000.
  • Ongoing election costs per four-year election cycle of $200,000. 

How will the districts be created? 

The county will be divided into five commissioner districts through the Redistricting Commission process. Each district will, as close as possible: 

  • Have one-fifth of the population of the county, 
  • maintain the current commissioners in their elected districts, 
  • follow precinct lines, 
  • maintain communities of mutual interest, 
  • be as compact and contiguous as possible, and 
  • not be gerrymandered. 

When will the new commissioners be appointed to the board?  

In Thurston County, county commissioners serve a four-year term. If approved by the voters, initially the district 4 commissioner will serve for a one-year term and the district 5 commissioner will serve a three-year term to allow for a staggered election cycle. After these initial terms, the new commissioner positions will serve four-year terms. The two newly created positions, district four and five commissioners, will be filled in during the general election in 2023.

What is the Redistricting Committee? 

The redistricting committee is made up of the chair of the Port Commission (voting member), chair of the Board of County Commissioners (voting member), and the Thurston County Auditor (non-voting member). The committee is supported by county and port staff including the county manager, county Information Technology department and elections staff, and the Port of Olympia’s executive director.
