This bill reenacts and amends RCW 36.70A.130 and imposes revised procedural requirements for continuing review and evaluation of comprehensive plans and development regulations by counties and cities. It allows cities or towns within counties planning under RCW 36.70A.040 to opt out of a full periodic review if they meet specified small-city criteria (population under 500, not within 10 miles of a city over 100,000, low growth rate) and notify "the department" (the specific department is not named in the extracted text). The department must review and notify eligible jurisdictions at least three years before a periodic update is due; opt-out jurisdictions must nonetheless update critical areas regulations, the capital facilities element, and the transportation element. The amendment defines "legislative action" for review findings, requires public participation programs consistent with existing RCW sections, and limits how often governing bodies may consider updates except for enumerated exceptions (including initial subarea plans with environmental review, certain economic development subarea plans, shoreline master program actions, capital facilities amendments with the budget, specified planned actions, and housing element amendments tied to compliance under RCW 36.70A.835). Reviews must address critical area ordinances and, for jurisdictions planning under RCW 36.70A.040, include analysis of OFM’s most recent 10-year population allocation. For counties designating urban growth areas (UGAs) the bill requires review of UGAs, development patterns, and densities to accommodate projected 20-year growth, and allows limited UGA adjustments for development pressure so long as total UGA area does not increase and specified conditions are met (areas added cannot be designated long-term agricultural/forest/mineral lands, most added areas cannot be critical areas except limited critical aquifer recharge areas, added areas must be suitable for urban growth, facilities and funding must be identified, UGAs must be contiguous and not create pressure on rural or resource lands, etc.). The act sets specific initial and periodic review deadlines by county groups (initial reviews between 2015 and 2018; periodic reviews clustered in 2024–2027 with ten-year cycles thereafter) and permits jurisdictions to conduct reviews before those deadlines. Procedural and financial changes include eligibility rules for grants, loans, and other financial assistance under several state programs based on compliance or "substantial progress" toward the deadlines; small counties and cities meeting certain criteria may get 24 additional months to comply after a deadline. The bill encourages state technical assistance, requires certain counties and larger cities to submit implementation progress reports five years after plan review (with department guidelines for measures and timelines), mandates corrective work plans where implementation is lagging with a two-year completion requirement, and ties inclusion of a climate change and resiliency element and transportation updates to funding availability by December 31, 2027 for jurisdictions reviewing by December 31, 2024. Important gaps in the extracted text include the identity of "the department," the remainder of subsection (6) and subsequent subsections referenced but not provided, missing details about the referenced state-funded pilot project, and full content of some cross-referenced RCW provisions.

If enacted, counties and cities will have to carry out scheduled, recurring reviews of their comprehensive plans and development regulations and will face specific requirements when adjusting urban growth areas, including identifying needed transportation and public facility funding and meeting strict limits on adding resource or sensitive lands. Small towns that meet narrow criteria (very small population, low growth, and distance from large cities) can avoid a full plan review but still must update critical areas rules, capital facilities, and transportation elements; jurisdictions may start reviews early and may be eligible for department grants or technical assistance if funding is available. The direct impacts fall mainly on county and city planning staffs and budgets: more routine planning work, new reporting and work-plan obligations for certain counties and larger cities, and potential costs to identify and fund needed infrastructure when UGAs change. Compliance or demonstrated substantial progress will affect eligibility and priority for state grants, loans, and financial guarantees, while failure to meet schedules can require mandated corrective work within set timelines. Important details are missing from the provided text—most notably which agency is the referenced “department,” several subsections that affect exceptions and definitions, and specifics about a referenced state-funded pilot project—so some implementation and funding consequences remain unclear.
