On March 1, 2018, the King County Executive transmitted to the King County Council the proposed 2018 update to the 2016 King County Comprehensive Plan as Proposed Ordinance 2018-0153. The 2018 update is a limited, annual cycle update, and will be focused on proposed changes to the County’s comprehensive planning schedule and to the subarea planning program. It is anticipated that the legislation will be referred to the Transportation, Economy and Environment Committee for review, with possible adoption by the full Council later this year.

Please check back to this website for more information the Council’s review of the proposal. You can also stay up to date on 2018 Comprehensive Plan news, schedules, and committee agendas by signing up for the Council’s Comprehensive Plan email list.

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 on either an annual or a once-every-four-years basis, depending on the scope of the change. The annual cycle 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 “four-year cycle” update is considered a larger-scale update to the plan and, unlike annual updates, allows for consideration of broader substantive policy changes and potential revisions to the Urban Growth Area.

The current plan is the 2016 Comprehensive Plan, which was adopted by the King County Council on December 5, 2016 and was amended in 2017 by Ordinance 18623. The 2016 Comprehensive Plan was the fifth major update to the King County Comprehensive Plan.
