Comprehensive Plan
What is the Seattle Comprehensive Plan?
The Comprehensive Plan is a 20 year vision and roadmap for Seattle’s future. Our Plan guides City decisions on where to build new jobs and houses, how to improve our transportation system, and where to make capital investments such as utilities, sidewalks, and libraries. The Plan is the framework for most of Seattle’s big-picture decisions on how to grow while preserving and improving our neighborhoods.
The One Seattle Plan
The One Seattle Comprehensive Plan includes goals and policies, along with an updated growth strategy, that will guide where and how Seattle grows and invests in communities over the next 20 years toward becoming a more affordable, resilient, and equitable city.
What's Happening Now?
Addressing the Growth Management Hearings Board Decision and Creating a Livable Seattle for All (October 2026)
On September 9, the Central Puget Sound Growth Management Hearings Board (GMHB) issued a decision on a legal challenge to our Comprehensive Plan.
The decision upheld the City’s Comprehensive Plan including our racial equity in housing and water infrastructure planning.
Unfortunately, the Board found our environmental impact statement (EIS) inadequate because the City did not analyze the “maximum possible development.” The Board has required the City to redo this technical analysis based on the “maximum possible development” rather than the 20-year growth estimates typically used.
This supplemental analysis is due in one year and we will start work on it immediately. The Comprehensive Plan and associated zoning changes adopted by City Council remain in effect while we prepare the new analysis.
At the same time, Mayor Wilson supports City Attorney Erika Evans’ decision to appeal the GMHB ruling in court.

We will continue this work with a focus on implementation, including several phases of zoning legislation and ongoing collaboration with City departments on next steps toward achieving the goals of the Plan. More information will be available on a new One Seattle Plan website that is forthcoming in 2026.
