Project Size: 515 Acres

Washington National Golf Club is located on 515 acres east and south of the Auburn-Black Diamond Road and west of 148th Avenue SE. Primary access to the facility is via 148th Avenue SE. Two 18-hole PGA type golf courses required a Conditional Use Permits under the existing King County AR-5 zoning.


The golf course design conforms to the natural terrain and character of the site and surrounding landscape. A minimum buffer of forested land, 100 feet wide, was retained around the perimeter of the site.


The scope of services provided by R. W. Thorpe & Associates included:


  • Land use site feasibility study
  • Layout and two 18-hole golf course routing options
  • Conditional Use Permit Application with expanded Environmental Checklist
  • Re-vegetation planting plan for buffers and slopes
  • Preliminary plat design and application
  • Best Management Practices Manual
  • Grading permit application
  • Marketing Reports
  • Environmental Impact Statement Review
  • Subsequent development of the Diamond Ridge Estates subdivision allowed for approximately 100 large lot single-family homes with frontage or views of the John Fought designed golf course.


Our chief roles as project managers were establishing consultant team tasks, scheduling, quality control, interfacing between client and King County. RWT/A also provided design and graphic support services for all phases of project: master planning, golf course layouts, facilities planning, hearing exhibits and report graphics
