King County Comprehensive Plan

King County Comprehensive 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.

Executive Recommended 2024 King County Comprehensive Plan

Throughout 2022-2023, the Executive asked for input and shared drafts of the 2024 Comprehensive Plan, a 20-year plan that guides where people live, work, and play in unincorporated communities (places outside of city limits). In December 2023, the Executive Recommended Plan was submitted to the King County Council. Read the proposals below to learn more about the specific actions King County is considering to address social equity, affordable housing, and climate change in our region.
