Washington Revised Code Title 52. Fire Protection Districts § 52.04.061. Annexation of proximate city or town--Procedure--Definition

(1) A city or town located within reasonable proximity to a fire protection district may be annexed to such district if at the time of the initiation of annexation the population of the city or town is 300,000 or less. The legislative authority of the city or town may initiate annexation by the adoption of an ordinance stating an intent to join the fire protection district and finding that the public interest will be served thereby. If the board of fire commissioners of the fire protection district shall concur in the annexation, notification thereof shall be transmitted to the legislative authority or authorities of the counties in which the city or town and the district are situated.

(2) For the purposes of this section, “reasonable proximity” means geographical areas near enough to each other so that governance, management, and services can be delivered effectively.
