The bill amends existing laws regarding the procedures for submitting certificates of annexation to the Office of Financial Management in Washington State. Key changes include the requirement that certificates must be submitted within thirty days of the effective date of the annexation action, and the original copy must be retained by the office while a copy is posted on the office's public website. The bill also specifies that a complete ordinance, including a legal description and a map of the annexed territory, must be included with the certificate. Additionally, the language has been updated to clarify that the population of the annexed territory will be determined by the mayor, and the city or town is responsible for the costs associated with this determination.

Furthermore, the bill outlines the methods for determining the resident population of the annexed territory, including the use of actual enumeration under certain conditions, and the reliance on updated census data when applicable. It establishes that until the annexation certificate is approved, the annexed territory will not be considered in the population calculations for state funding allocations. The bill aims to streamline the annexation process and ensure accurate population assessments for funding purposes.
