Proposed public rules
To propose a public rule, we publish a Notice of Intent to Adopt Rules in The Seattle Times, which is the official paper of record for King County. We also post proposed rules on this page.
You may comment on the proposed public rules within a 45-day comment period. We may then adopt the public rules, which become effective after 30 days. If substantive changes are made in response to public comments, then the adoption process—including another public comment period—must start over.
Current proposed rule change: channel migration
The Department of Local Services intends to adopt a public rule, pursuant to authority granted it by King County Code chapter 2.98. The purpose of this rule is to implement King County Code Section 21A.24.274.A by adopting criteria for channel migration designation, classification, and mapping, and channel migration zone studies and channel migration zone maps for the Lower Snoqualmie Channel Migration Zone. Learn more and sign up for updates on the public engagement site.
Any interested person may submit written comments about this proposed rule. Comments must be received by the Department of Local Services no later than 5 p.m. on August 6, 2025.
