This bill expresses an intent to pursue a constitutional amendment to divide Washington into two autonomous regions — a Puget Sound region and a Columbia region — each envisioned to have its own regional governor, regional legislature, and regional judiciary. It defines the Puget Sound region as Clallam, Grays Harbor, Island, Jefferson, King, Kitsap, Mason, Pierce, San Juan, Skagit, Snohomish, Thurston, and Whatcom counties, and the Columbia region as Adams, Asotin, Benton, Chelan, Clark, Columbia, Cowlitz, Douglas, Ferry, Franklin, Garfield, Grant, Kittitas, Klickitat, Lewis, Lincoln, Okanogan, Pacific, Pend Oreille, Skamania, Spokane, Stevens, Wahkiakum, Walla Walla, Whitman, and Yakima counties. The act creates new statutory sections (Sec. 1, Sec. 2, Sec. 3) to establish a joint legislative task force to plan the creation of the two regions and to select members of two regional committees (a Puget Sound region committee and a Columbia region committee) that will evaluate and recommend strategies for creating the autonomous regions. The bill is procedural and organizational in nature: it sets up bodies and deadlines rather than immediately altering the state constitution or creating criminal penalties. The joint legislative task force membership is listed (lieutenant governor; majority and minority leaders of the house and senate); regional committees must include representatives from federally recognized tribes in each region, sector representatives (community banking, agricultural, forestry, transportation, energy, environmental), a judicial official from each region, a Code Reviser representative, and caucus staff from the two largest caucuses. The lieutenant governor must convene the initial task force meeting within 90 days after adjournment of the session in which the act passes; each regional committee chair must convene its initial meeting within 30 days after members are selected; the task force must report its plan to the appropriate legislative committees by December 31, 2026. Task force expenses are to be paid jointly by the senate and house, with expenditures subject to approval by the senate facilities and operations committee and the house executive rules committee (or their successors); members are reimbursed per RCW 44.04.120. The act may be cited as the "win-win for Washington act" and cites the National Environmental Policy Act and Article I, section 1 of the state constitution. Important implementation details are not included in the provided text: the actual text of any constitutional amendment or the process for placing an amendment before voters is not provided; the mechanism for selecting or appointing the tribal, sector, and judicial representatives is not specified; procedures for how counties or precincts may join a region beyond geographic listing are not described; and specific funding amounts or sources beyond joint legislative payment are not stated.

If enacted, the bill launches a formal planning process to pursue a constitutional amendment to split Washington into two autonomous regions by creating a joint legislative task force and two regional committees with specified membership (legislative leaders, tribal reps, sector reps, caucus staff, a Code Reviser rep, and a judicial rep) and set deadlines for convening and for a final plan due December 31, 2026. Practically, that means legislative leaders and the named county, tribal, and sector representatives will be asked to spend time and state resources on meetings, travel (reimbursed under existing state rules), and planning work, and the legislature (both the senate and house) will jointly pay task force expenses subject to approval by their respective oversight committees. The bill does not specify how a constitutional amendment would actually be written, put to voters, how committee members will be chosen in detail, how counties might change regions, or how much money will be required, so there is real uncertainty about the timeline, final costs, and legal steps that would follow the planning work.
