(1) The board may determine that part or all of a comprehensive plan or development regulations are invalid if the board:

(a) Makes a finding of noncompliance and issues an order of remand under RCW 36.70A.300;

(b) Includes in the final order a determination, supported by findings of fact and conclusions of law, that the continued validity of part or parts of the plan or regulation would substantially interfere with the fulfillment of the goals of this chapter; and

(c) Specifies in the final order the particular part or parts of the plan or regulation that are determined to be invalid, and the reasons for their invalidity.

(2) A determination of invalidity is prospective in effect and does not extinguish rights that vested under state or local law before receipt of the board's order by the city or county. The determination of invalidity does not apply to a completed development permit application for a project that vested under state or local law before receipt of the board's order by the county or city or to related construction permits for that project.

(3)(a) Except as otherwise provided in subsection (2) of this section and (b) of this subsection, a development permit application not vested under state or local law before receipt of the board's order by the county or city vests to the local ordinance or resolution that is determined by the board not to substantially interfere with the fulfillment of the goals of this chapter.

(b) Even though the application is not vested under state or local law before receipt by the county or city of the board's order, a determination of invalidity does not apply to a development permit application for:

(i) A permit for construction by any owner, lessee, or contract purchaser of a single-family residence for his or her own use or for the use of his or her family on a lot existing before receipt by the county or city of the board's order, except as otherwise specifically provided in the board's order to protect the public health and safety;

(ii) A building permit and related construction permits for remodeling, tenant improvements, or expansion of an existing structure on a lot existing before receipt of the board's order by the county or city; and

(iii) A boundary line adjustment or a division of land that does not increase the number of buildable lots existing before receipt of the board's order by the county or city.

(4) If the ordinance that adopts a plan or development regulation under this chapter includes a savings clause intended to revive prior policies or regulations in the event the new plan or regulations are determined to be invalid, the board shall determine under subsection (1) of this section whether the prior policies or regulations are valid during the period of remand.

(5) A county or city subject to a determination of invalidity may adopt interim controls and other measures to be in effect until it adopts a comprehensive plan and development regulations that comply with the requirements of this chapter. A development permit application may vest under an interim control or measure upon determination by the board that the interim controls and other measures do not substantially interfere with the fulfillment of the goals of this chapter.

(6) A county or city subject to a determination of invalidity may file a motion requesting that the board clarify, modify, or rescind the order. The board shall expeditiously schedule a hearing on the motion. At the hearing on the motion, the parties may present information to the board to clarify the part or parts of the comprehensive plan or development regulations to which the final order applies. The board shall issue any supplemental order based on the information provided at the hearing not later than thirty days after the date of the hearing.

(7)(a) If a determination of invalidity has been made and the county or city has enacted an ordinance or resolution amending the invalidated part or parts of the plan or regulation or establishing interim controls on development affected by the order of invalidity, after a compliance hearing, the board shall modify or rescind the determination of invalidity if it determines under the standard in subsection (1) of this section that the plan or regulation, as amended or made subject to such interim controls, will no longer substantially interfere with the fulfillment of the goals of this chapter.

(b) If the board determines that part or parts of the plan or regulation are no longer invalid as provided in this subsection, but does not find that the plan or regulation is in compliance with all of the requirements of this chapter, the board, in its order, may require periodic reports to the board on the progress the jurisdiction is making towards compliance.
