Mayor Harrell transmits permanent legislation to comply with HB 1110
With the passage of the interim legislation, Mayor Harrell transmitted proposed permanent legislation to update Neighborhood Residential zoning and comply with HB 1110. The permanent legislation includes a complete update to Neighborhood Residential zoning. The legislation makes other changes to Lowrise zoning to comply with state law and to further City goals. A summary of the legislation (called the Director’s Report) as well as its full text is available on our Zoning Update website.
We released a summary of the public feedback received in Fall of 2024 on the draft proposal to update Neighborhood Residential zones and implement rezones in Neighborhood Centers, Center Expansions, and Frequent Transit Corridors. This feedback was used to develop the legislation that was recently sent to Council.
Mayor Harrell transmits Comprehensive Plan legislation to Council
Mayor Harrell also transmitted proposed legislation to update the City’s Comprehensive Plan. This legislation will replace the current Seattle 2035 Comprehensive Plan with the new One Seattle Plan. The One Seattle 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.
A preliminary version of the One Seattle Plan was previously released in January 2025. Final legislation has been introduced at the Select Committee on the Comprehensive Plan, with minor changes, including a revised future land use map with boundary adjustments for selected Regional, Urban, and Neighborhood Centers. A summary of the legislation (called the Director’s Report) as well as other supporting documents are available on our One Seattle Plan website.
Council has released a proposed schedule for deliberating on the permanent HB 1110 legislation and the legislation to adopt the Mayor’s Recommended One Seattle Plan. Key dates include the following:
- June 5: Initial presentation on the proposed legislation
- June 23: Public hearing
- September: Anticipated Council Vote
