About the King County Comprehensive Plan

The King County Comprehensive Plan is the guiding policy document for land use and development regulations in unincorporated King County, and for regional services throughout the County including transit, sewers, parks, trails, and open space.

The King County Code (K.C.C. 20.18.030) allows for updates to the Comprehensive Plan King County's review schedule includes annual, midpoint, and eight-year updates. The annual update allows for limited changes, technical corrections, adoption of subarea plans, and adoption of land use changes that do not amend the Urban Growth Area. The midpoint update, an optional update authorized for year 4 of the eight-year cycle, is limited to what is included in motion describing the scope of work. The eight-year update is a full review and update to the entire Comprehensive Plan, and is mandated by the Growth Management Act requirements.
