However, the county legislative authority of such a county with a population of less than fifty thousand population may adopt a resolution removing the county, and the cities located within the county, from the requirements of adopting comprehensive land use plans and development regulations under this chapter if this resolution is adopted and filed with the department by December 31, 1990, for counties initially meeting this set of criteria, or within sixty days of the date the office of financial management certifies that a county meets this set of criteria under subsection (5) of this section. For the purposes of this subsection, a county not currently planning under this chapter is not required to include in its population count those persons confined in a correctional facility under the jurisdiction of the department of corrections that is located in the county. Once a county meets either of these sets of criteria, the requirement to conform with all of the requirements of this chapter remains in effect, even if the county no longer meets one of these sets of criteria. (2)(a) The county legislative authority of any county that does not meet either of the sets of criteria established under subsection (1) of this section may adopt a resolution indicating its intention to have subsection (1) of this section apply to the county. Each city, located in a county that chooses to plan under this subsection, shall conform with all of the requirements of this chapter. Once such a resolution has been adopted, the county and the cities located within the county remain subject to all of the requirements of this chapter, unless the county subsequently adopts a withdrawal resolution for partial planning pursuant to (b)(i) of this subsection. (b)(i) Until December 31, 2015, the legislative authority of a county may adopt a resolution removing the county and the cities located within the county from the requirements to plan under this section if: (A) The county has a population, as estimated by the office of financial management, of twenty thousand or fewer inhabitants at any time between April 1, 2010, and April 1, 2015; (B) The county has previously adopted a resolution indicating its intention to have subsection (1) of this section apply to the county; (C) At least sixty days prior to adopting a resolution for partial planning, the county provides written notification to the legislative body of each city within the county of its intent to consider adopting the resolution; and (D) The legislative bodies of at least sixty percent of those cities having an aggregate population of at least seventy-five percent of the incorporated county population have not: Adopted resolutions opposing the action by the county; and provided written notification of the resolutions to the county. (ii) Upon adoption of a resolution for partial planning under (b)(i) of this subsection: (A) The county and the cities within the county are, except as provided otherwise, no longer obligated to plan under this section; and (B) The county may not, for a minimum of ten years from the date of adoption of the resolution, adopt another resolution indicating its intention to have subsection (1) of this section apply to the county. (c) The adoption of a resolution for partial planning under (b)(i) of this subsection does not nullify or otherwise modify the requirements for counties and cities established in RCW 36.70A.060 , 36.70A.070 (5) and associated development regulations, 36.70A.170 , and 36.70A.172 . (3) Any county or city that is initially required to conform with all of the requirements of this chapter under subsection (1) of this section shall take actions under this chapter as follows: (a) The county legislative authority shall adopt a countywide planning policy under RCW 36.70A.210 ; (b) the county and each city located within the county shall designate critical areas, agricultural lands, forestlands, and mineral resource lands, and adopt development regulations conserving these designated agricultural lands, forestlands, and mineral resource lands and protecting these designated critical areas, under RCW 36.70A.170 and 36.70A.060 ; (c) the county shall designate and take other actions related to urban growth areas under RCW 36.70A.110 ; and (d) if the county has a population of fifty thousand or more, the county and each city located within the county shall adopt a comprehensive plan under this chapter and development regulations that are consistent with and implement the comprehensive plan on or before July 1, 1994, and if the county has a population of less than fifty thousand, the county and each city located within the county shall adopt a comprehensive plan under this chapter and development regulations that are consistent with and implement the comprehensive plan by January 1, 1995, but if the governor makes written findings that a county with a population of less than fifty thousand or a city located within such a county is not making reasonable progress toward adopting a comprehensive plan and development regulations the governor may reduce this deadline for such actions to be taken by no more than one hundred eighty days. Any county or city subject to this subsection may obtain an additional six months before it is required to have adopted its development regulations by submitting a letter notifying the department of its need prior to the deadline for adopting both a comprehensive plan and development regulations. (4) Any county or city that is required to conform with all the requirements of this chapter, as a result of the county legislative authority adopting its resolution of intention under subsection (2) of this section, shall take actions under this chapter as follows: (a) The county legislative authority shall adopt a countywide planning policy under RCW 36.70A.210 ; (b) the county and each city that is located within the county shall adopt development regulations conserving agricultural lands, forestlands, and mineral resource lands it designated under RCW 36.70A.060 within one year of the date the county legislative authority adopts its resolution of intention; (c) the county shall designate and take other actions related to urban growth areas under RCW 36.70A.110 ; and (d) the county and each city that is located within the county shall adopt a comprehensive plan and development regulations that are consistent with and implement the comprehensive plan not later than four years from the date the county legislative authority adopts its resolution of intention, but a county or city may obtain an additional six months before it is required to have adopted its development regulations by submitting a letter notifying the department of its need prior to the deadline for adopting both a comprehensive plan and development regulations. (5) If the office of financial management certifies that the population of a county that previously had not been required to plan under subsection (1) or (2) of this section has changed sufficiently to meet either of the sets of criteria specified under subsection (1) of this section, and where applicable, the county legislative authority has not adopted a resolution removing the county from these requirements as provided in subsection (1) of this section, the county and each city within such county shall take actions under this chapter as follows: (a) The county legislative authority shall adopt a countywide planning policy under RCW 36.70A.210 ; (b) the county and each city located within the county shall adopt development regulations under RCW 36.70A.060 conserving agricultural lands, forestlands, and mineral resource lands it designated within one year of the certification by the office of financial management; (c) the county shall designate and take other actions related to urban growth areas under RCW 36.70A.110 ; and (d) the county and each city located within the county shall adopt a comprehensive land use plan and development regulations that are consistent with and implement the comprehensive plan within four years of the certification by the office of financial management, but a county or city may obtain an additional six months before it is required to have adopted its development regulations by submitting a letter notifying the department of its need prior to the deadline for adopting both a comprehensive plan and development regulations.

(8) A federally recognized Indian tribe may voluntarily choose to participate in the county or regional planning process and coordinate with the county and cities that are either required to comply with the provisions of this chapter pursuant to subsection (1) of this section or voluntarily choose to comply with the provisions of this chapter pursuant to subsection (2) of this section. Collaboration and participation is a nonexclusive exercise of coordination and cooperation in the planning process and failure to exercise discretionary collaboration and participation shall not limit a party's standing for quasi-judicial or judicial review or appeal under this chapter. (a) Upon receipt of notice in the form of a tribal resolution from a federally recognized Indian tribe whose reservation or ceded lands lie within the county, which indicates the tribe has a planning process or intends to initiate a parallel planning process, the county, cities, and other local governments conducting the planning under this chapter shall enter into good faith negotiations to develop a mutually agreeable memorandum of agreement with such tribes in regard to collaboration and participation in the planning process. If a mutually agreeable memorandum of agreement cannot be reached between the local government and such tribes, the local government shall enter mediation with such tribes for a period not to exceed 30 days, which shall be arranged by the department using a suitable expert to be paid by the department. If a mutually agreeable memorandum of agreement is not reached at the conclusion of the mediation period, the period shall be extended for one additional period not to exceed 30 days, upon written notice to the department by one or more parties. If a mutually agreeable memorandum of agreement cannot be reached at the end of the mediation period or the extended mediation period, the parties shall have no further obligation to develop a memorandum of agreement. Inability to reach a mutually agreeable memorandum of agreement shall not preclude a tribe from providing notice as described in this subsection (8)(a) in subsequent planning processes. (b) Nothing in this subsection, any other provision in this chapter, or a tribe's decision to become a participating tribe for planning purposes, shall affect, alter, or limit in any way a tribe's authority, jurisdiction, or any treaty or other rights it may have by virtue of its status as a sovereign Indian tribe. (c) Nothing in this subsection or any other provision in this chapter shall affect, alter, or limit in any way a local government legislative body's authority to adopt and amend comprehensive land use plans and development regulations in accordance with this chapter.
