Wash. Rev. Code § 28A.335.020
Before any school closure, a school district board of directors shall adopt a policy regarding school closures which provides for citizen involvement before the school district board of directors considers the closure of any school for instructional purposes. The policy adopted shall include provisions for the development of a written summary containing an analysis as to the effects of the proposed school closure. The policy shall also include a requirement that during the ninety days before a school district's final decision upon any school closure, the school board of directors shall conduct hearings to receive testimony from the public on any issues related to the closure of any school for instructional purposes. The policy shall require separate hearings for each school which is proposed to be closed.
The policy adopted shall provide for reasonable notice to the residents affected by the proposed school closure. At a minimum, the notice of any hearing pertaining to a proposed school closure shall contain the date, time, place, and purpose of the hearing. Notice of each hearing shall be published once each week for two consecutive weeks in a newspaper of general circulation in the area where the school, subject to closure, is located. The last notice of hearing shall be published not later than seven days immediately before the final hearing.
