PLU Master Plan

Pierce County is preparing the Pierce County Airport-Thun Field Master Plan to identify the 20-year improvements for the airport. The master plan will identify long-term needs for facilities, equipment and services to position Pierce County Airport-Thun Field to accommodate community growth. 

The 18-month process to update the master plan began in October 2017.  

The plan will:

  • Position the airport to meet community growth and interests
  • Accommodate existing and future aviation demands as envisioned by Pierce County
  • Align recommendations with Pierce County revenue and return benefit
  • Meet Federal Aviation Administration (FAA) safety standards and grant assurances
At the end of the process, we will have a year-by-year facility improvement plan which brings projects, people, and funding resources together in a coordinated manner.

Mead & Hunt has been selected to lead the update on Pierce County's behalf.


The update is expected to cost approximately $453,000. An FAA grant will fund $408,000, while a WSDOT grant will fund $22,500. A Pierce County local match will fund the remaining $22,500.


Master Plan Narrative Chapters (Working Papers)

The plan includes the following narrative report chapters used to document findings and decisions made during the planning process. Narrative chapters (working papers) will be uploaded to this webpage following review by Pierce County, the Federal Aviation Administration (FAA), and the Washington State Department of Transportation (WSDOT).
