King County Comprehensive Plan

Learn more about what the Comprehensive Plan covers and get details on the 2024 update.

About the plan

The central Puget Sound region is growing. Every day in 2019, the region gained 166 people. The Puget Sound Regional Council projects that the region will continue to grow and add another 1.8 million people and 1.2 million jobs by 2050.

The Comprehensive Plan is a key policy document that guides how growth and development will occur over the next 20 years. It guides County decisions and services such as:

  • where homes, offices, or stores can be built;
  • how roads, buildings and trees contribute to the look and feel of neighborhoods;
  • investments in transit, sewers, and parks;
  • protection of working farms and forests; and
  • access to clean water, clean air, and a healthy environment.

The 2024 update

King County has started a once-a-decade update to its Comprehensive Plan, which guides where people live, work, and play in unincorporated King County. While this is known as the "2024 Update" the process for developing the plan takes place over two years. Please see the planned timeline below. To ensure that King County will be a welcoming community where every person can thrive, the 2024 update focuses on policies related to racial equity, affordable housing, and climate change. More details about the scope of the update can be found here. There will be many opportunities during the planning process for all county residents and the general public to provide input on the update, until it is adopted by Council in December of 2024.

2024 Critical Areas Ordinance Update

Supplemental Changes to 2024 Executive Recommended 2024 Plan

As required by the Washington State Growth Management Act, part of the 2024 King County Comprehensive Plan update (2024 Update) includes a review of and update to the policies and regulations used to protect public health and safety by limiting development in hazard areas, including steep slopes and flood zones, and to protect environmentally critical areas, including wetlands and streams. Regulations in King County Code that protect critical areas are often referred to as the Critical Areas Ordinance (CAO) and are required to reflect the latest best available science (BAS).

To provide for additional government-to-government consultation with Indian tribes and engagement with community partners, drafting and submittal of additional BAS-driven CAO and policy changes are on a slightly later timeline than the December 2023 submittal of the 2024 Update to the King County Council. The Executive Recommended CAO updates, related policy changes, and supporting BAS report were submitted to the Council on March 1, 2024. The proposed changes will get folded into the 2024 Update and follow the Council's review, amendment, and adoption process for the rest of 2024 to meet the state adoption deadline of December 31, 2024.

To provide input to the Council on the proposals, send an email to CouncilCompPlan@kingcounty.gov. Other opportunities for public input will occur throughout 2024 with the Council. Learn more here.

Draft Environmental Impact Statement Review

King County has issued a Draft Environmental Impact Statement (DEIS) for the 2024 Update. Read the draft here.  

Between December 7, 2023 and January 31, 2024, the County provided a public comment period. Over a dozen comments were submitted and these are compiled in a DEIS Public Comments Report. Consistent with state requirements for environmental review, the comments and responses will be published in the Final EIS which is scheduled to be released in November 2024 in advance of the County Council’s adoption of the 2024 Comprehensive Plan Update.

FAQs

Why does King County have a Comprehensive Plan?

In 1990, the Washington state legislature enacted the Growth Management Act (GMA) in response to rapid and uncoordinated growth at the time. In addition to aligning state, multi-county, countywide, and local planning, the GMA requires local governments in fast-growing and densely populated areas to develop and adopt comprehensive plans. King County’s planning role is complex in that it is responsible for regional services and is also the local government to unincorporated areas. Thus, King County’s Comprehensive Plan offers a vision for how unincorporated areas will grow and how regional services – such as transit, parks and solid waste – will be provided.

The policies throughout the plan support good planning principles such as directing new homes and jobs to areas near current and planned transit centers. Another is that rural and resource lands are protected through an urban growth boundary, which allows our region to keep working farms and forests.

 

What is an unincorporated area?

Unincorporated areas are areas outside of city limits. If you live or do business in neighborhoods such as Skyway, White Center, Vashon-Maury Island, or Redmond Ridge, King County is your main provider of local government services.

Here are two ways to find out if you are located in an unincorporated area:

  • Find or enter your address on this map. The green layer shows unincorporated King County.
  • Enter your address in King County’s Parcel Viewer and see what’s listed as the jurisdiction.

 

What does the comprehensive plan say about the future of my community?

The land use map in the Comprehensive Plan shows the general types of planned, long-term uses allowed on each parcel of land. This informs the zoning category applied to each parcel, which sets more specific, current allowed uses and associated development regulations. You can search for a parcel's land use and zoning here. The plan also includes policies about specific topics, such as housing or parks, which are grouped in the plan by chapter.

 

Who is responsible for developing and approving the Comprehensive Plan?

In The King County Executive is responsible for developing the Comprehensive Plan and sending it to the King County Council for final review and approval. When developing the Comprehensive Plan, the Executive works in coordination with regional and local jurisdictional partners and the public. Public input is welcome throughout the process and there are many opportunities to submit comments and make requests. The Executive considers all comments in developing the Executive Recommended Plan. The King County Council reviews the plan, proposes amendments, and votes on whether to adopt the final version.

 

How often is the plan updated?

There are three types of updates: technical adjustments, limited updates, and major updates.

  • Every year, there is an opportunity to make technical adjustments to the plan and minor changes to land use designations and zoning classifications.
  • Once every five years, a limited range of substantive changes can be considered. At this time, the county also conducts a study of how much of the predicted growth has happened and evaluates policies to see if they are effective at accommodating it. The next possible five-year update would be in 2029.
  • Finally, at least once every ten years, King County is required to review and update the plan to ensure compliance with the goals and requirements of the GMA. These updates are also an opportunity to make in-depth and broad ranging policy changes that address changes in the community's growth and long-term needs, while advancing the County's policy goals.

 

How do I submit changes, make recommendations or stay involved?

  • To submit specific policy recommendations or changes to land use and zoning, please use the docket application process
  • If you have general comments or suggestions for a current plan update (such as the 2024 update), please submit feedback to CompPlan@kingcounty.gov
  • King County planning staff are available to meet with community groups and other interested parties. Please submit requests to CompPlan@kingcounty.gov
  • Sign up for news about plan updates and Comprehensive Plan topics by joining our mailing list.
