Countywide Planning Policies

Updated Through October 21, 2020

On September 17, 2020, members of Rural Area unincorporated area councils and associations attended a Seminar on the Countywide Planning Policies (CPPs) given by Sr. Policy Analyst and Staff Contact to the Growth Management Planning Council (GMPC), Karen Wolf,  and King County Demographer, Rebeccah Maskin, and arranged by the GMVUAC. The CPPs, currently undergoing an Update, serve as the guiding principles and policies for all Comprehensive Planning in King County (County, City, and Special-Purpose District), as well as County and City Zoning Codes. The Seminar reviewed the CPPs, the ongoing update, and included a robust question/answer period.

The King County Growth Management Planning Council (GMPC)—a formal body, consisting of elected officials from King County, Seattle, Bellevue, other cities/towns in King County, special purpose districts, and the Port of Seattle—is updating King County’s 2012 (as amended in 2016: CPPs by the end of this year.

The CPPs provide a countywide vision and serve as a framework for all City Comprehensive Plan updates, which must be consistent with the overall vision for the future of King County. Please see:

The CPPs establish: (1) The Urban Growth Area (UGA) boundary; (2) Criteria for revising UGA Growth Targets for each jurisdiction; and (3) Criteria for defining urban centers and manufacturing/industrial centers. The new set of Growth Targets for each jurisdiction will have impacts on transportation infrastructure throughout the County.

The GMPC’s current schedule (subject to change) is: Growth Target Methodology (April 2020); Urban Growth Capacity (UGC), Countywide Planning Policies (CPPs) Update, & Growth Targets (June 2020); and CPP and UGC Public Review Drafts (September 2020). Final Actions on both the CPPs and the UGC Report are expected by the end of 2020. For more information, please see:
