Concerning city incorporation.

SB 6181 amends Washington state law to change requirements for incorporating new cities. It requires incorporation petitions to be signed by at least 10% of registered voters living in the proposed area, filed with the county auditor within 180 days of a public meeting. The bill adds an exception for counties west of the Cascades with populations between 900,000-2,000,000: these counties can file incorporation petitions without resident signatures if the area is within an urban growth boundary and has over 25,000 residents. This affects communities seeking incorporation and counties meeting the specified population criteria. The bill focuses on procedural changes to the petition process, not substantive policy.
