Wash. Rev. Code § 57.28.080
The petition shall be heard at the time and place specified in the notice, or the hearing may be adjourned from time to time, not exceeding one month in all, and any person may appear at the hearing and make objections to the withdrawal of the territory. Upon final hearing on the petition the county legislative authority shall thereupon make, enter, and by resolution adopt its findings of fact on the questions set forth in RCW 57.28.050. If the findings of fact answer the questions affirmatively, and if they are the same as the findings made by the district commissioners, then the county legislative authority shall by resolution declare that the territory be withdrawn from that district, and thereupon the territory shall be withdrawn and excluded from that district the same as if it had never been included therein except for the lien of taxes as hereinafter set forth. However, the boundaries of the territory withdrawn shall be the boundaries established and defined by the district board of commissioners and shall not be altered or changed by the county legislative authority unless the unanimous consent of the district commissioners be given in writing to any such alteration or change.
