Wash. Rev. Code § 36.93.150 (2026)

The board, upon review of any proposed action, shall take such of the following actions as it deems necessary to best carry out the intent of this chapter:

(1) Approve the proposal as submitted.

(2) Subject to RCW 35.02.170, modify the proposal by adjusting boundaries to add or delete territory. Subject to the requirements of this chapter, a board may modify a proposal by adding territory that would increase the total area of the proposal before the board. A board, however, may not modify a proposal for annexation of territory to a city or town by adding an amount of territory that constitutes more than one hundred percent of the total area of the proposal before the board. Any modifications shall not interfere with the authority of a city, town, or special purpose district to require or not require preannexation agreements, covenants, or petitions. A board shall not modify the proposed incorporation of a city with an estimated population of seven thousand five hundred or more by removing territory from the proposal, or adding territory to the proposal, that constitutes ten percent or more of the total area included within the proposal before the board. However, a board shall remove territory in the proposed incorporation that is located outside of an urban growth area or is annexed by a city or town, and may remove territory in the proposed incorporation if a petition or resolution proposing the annexation is filed or adopted that has priority over the proposed incorporation, before the area is established that is subject to this ten percent restriction on removing or adding territory. A board shall not modify the proposed incorporation of a city with a population of seven thousand five hundred or more to reduce the territory in such a manner as to reduce the population below seven thousand five hundred.

(3) Determine a division of assets and liabilities between two or more governmental units where relevant.

(4) Determine whether, or the extent to which, functions of a special purpose district are to be assumed by an incorporated city or town, metropolitan municipal corporation, or another existing special purpose district.

(5) Disapprove the proposal except that the board shall not have jurisdiction: (a) To disapprove the dissolution or disincorporation of a special purpose district which is not providing services but shall have jurisdiction over the determination of a division of the assets and liabilities of a dissolved or disincorporated special purpose district; (b) over the division of assets and liabilities of a special purpose district that is dissolved or disincorporated pursuant to chapter 36.96 RCW; nor (c) to disapprove the incorporation of a city with an estimated population of seven thousand five hundred or more, but the board may recommend against the proposed incorporation of a city with such an estimated population.

Unless the board disapproves a proposal, it shall be presented under the appropriate statute for approval of a public body and, if required, a vote of the people. A proposal that has been modified shall be presented under the appropriate statute for approval of a public body and if required, a vote of the people. If a proposal, other than that for a city, town, or special purpose district annexation, after modification does not contain enough signatures of persons within the modified area, as are required by law, then the initiating party, parties or governmental unit has thirty days after the modification decision to secure enough signatures to satisfy the legal requirement. If the signatures cannot be secured then the proposal may be submitted to a vote of the people, as required by law.

The addition or deletion of property by the board shall not invalidate a petition which had previously satisfied the sufficiency of signature provisions of RCW 35.13.130 or 35A.14.120. When the board, after due proceedings held, disapproves a proposed action, such proposed action shall be unavailable, the proposing agency shall be without power to initiate the same or substantially the same as determined by the board, and any succeeding acts intended to or tending to effectuate that action shall be void, but such action may be reinitiated after a period of twelve months from date of disapproval and shall again be subject to the same consideration.

The board shall not modify or deny a proposed action unless there is evidence on the record to support a conclusion that the action is inconsistent with one or more of the objectives under RCW 36.93.180. The board may not increase the area of a city or town annexation unless it holds a separate public hearing on the proposed increase and provides ten or more days' notice of the hearing to the registered voters and property owners residing within the area subject to the proposed increase. Every such determination to modify or deny a proposed action shall be made in writing pursuant to a motion, and shall be supported by appropriate written findings and conclusions, based on the record.
