We’re working with Seattle Public Utilities to update Seattle’s Stormwater Code and Stormwater Manual as required by the Washington State Department of Ecology.
The second draft of the updated Code and Manual documents will be available for public review and comment the week of January 5.
We’re holding a public meeting on January 14, 1 PM to 3 PM to describe the changes in the first draft of the Code and Manual and significant subsequent changes in the second draft. Please register to attend the meeting.
Stay tuned for further announcements in early January with links to the documents and detailed instructions on how to comment. This information, along with information on past public meetings, is available on SDCI’s Stormwater Code and Manual Update 2026 website.
