This bill amends RCW 36.70A.367 to create a county-level mechanism for designating an "industrial land bank" of up to two master planned locations for major industrial activity outside urban growth areas. It establishes a two-step approval process: (1) designate an industrial land bank area by comprehensive plan amendment, and (2) approve specific major industrial developments within that area through a local master plan process without requiring a further comprehensive plan amendment. The change modifies existing law by adding this designation process and related procedural requirements; it does not create a new criminal offense or change penalties. The amended law defines "major industrial development" and "industrial land bank," sets mandatory comprehensive plan content and programmatic environmental review, and requires counties to adopt development regulations for master plans that address specified items. Key procedural and substantive requirements include prioritizing sites near urban growth areas, identifying maximum site size and limitations, interlocal agreements with service providers at the time of master plan approval, infrastructure to be provided concurrent with development (with impact fees to assure adequate facilities), a limit of no more than 10% of gross floor area for commercial/service uses within a major industrial development, and public notice and hearing rules (including at least 30 days' published notice and mailed notice to owners within one mile). The amendment affects counties planning under RCW 36.70A.040, cities (consultation required), service providers, the county legislative body and hearing authorities, and the Office of Financial Management for one density determination. It references multiple other RCWs for definitions and periodic review timelines. The text makes temporal provisions about when counties must act: an authority to designate previously was tied to periodic review dates prior to December 31, 2016, and qualifying rural counties may designate and adopt regulations within two years of their next periodic review date occurring prior to December 31, 2027. The chunked text references other statutes for full procedural context, and the interplay between the 2016 expiration provision and the later 2027 timelines, as well as some parenthetical formatting in the source, is unclear without consulting the referenced RCWs and the full bill text.

If enacted, counties that choose to use this authority can set aside up to two large, master-planned industrial sites outside urban growth areas for businesses that need unusually large parcels, proximity to natural resources, or special transportation access. That gives counties and nearby cities a clear pathway to approve such developments through a comprehensive plan amendment plus a local master plan process, while requiring environmental review, development rules, and interlocal agreements with service providers before final master plan approval. The practical impacts are that counties will need to spend time and money to prepare plan amendments, programmatic environmental reviews, new development regulations, and negotiate interlocal service agreements; service districts and cities may face new service and infrastructure responsibilities timed to development and will rely on impact fees paid by developers to cover costs. Developers of these sites must accept limits on commercial or service space (no more than 10% of total floor area) and will be expected to fund or phase infrastructure; counties that fail to act within the specified periodic-review windows may lose the ability to designate sites, and there is some uncertainty in the text about how earlier expiration language and later rural-county timelines interact.
