PBRS Resource Information

Public Benefit Rating System application

Timber Land application

The Public Benefit Rating System (PBRS) and the Timber Land programs provide incentives to encourage landowners to voluntarily conserve and protect land resources, open space and timber. In return for preserving and managing resources, the land is assessed at a value consistent with its "current use" rather than the "highest and best use." The reduction in assessed land value is greater than 50% and as much as 90% for the portion of the land participating in the program. Over 1075 landowners and 10,400 acres are presently participating in these two programs.

  • Public Benefit Rating System (PBRS): for property qualifying for one or more of the defined resources in the Resource Information document. Examples of open space resources include stream buffers, ground water protection areas, threatened or endangered wildlife, farmland, forestland, public recreation, historic property and others.
  • Timber Land program: for property containing between five (5) to twenty (20) acres of forestland, zoned RA, F or A and devoted to the growth and harvest of timber. The owner must have an approved and implemented forest stewardship plan.

Other resource programs

Property, the resource land only, is also eligible to participate in one of the two other current use assessment programs available in King County:

  • Forestland: for property containing more than twenty (20) acres primarily devoted to the growth and harvest of timber. This program is administered by the King County Assessor's Office.
  • Farm and Agricultural Lands: for property used for the production of livestock or agricultural commodities for commercial purposes. The financial requirements are dependent on the size of the land and the gross annual revenue received for the land for three out of the past five years. This program is administered by the King County Assessor's Office.

Please refer to the right of this page for the appropriate document or staff member for specific requirements of each program. The annual application deadline for all four programs is December 31 (one year in advance of the expected assessed value reduction). For property located in the unincorporated area, the application fee for PBRS and Timber Land has been waived through 2008.
