The proposed bill aims to establish two autonomous regions in Washington State: the Puget Sound region and the Columbia region. It recognizes the growing urban-rural divide within the state and asserts the right of the people to alter their government when it fails to represent them. The bill outlines the intention to create regional governance structures, including regional governors, legislators, and judges, while maintaining Washington as a single state for federal purposes. The boundaries for these regions are defined, with the Columbia region encompassing counties east of the Cascade mountain range and the Puget Sound region including counties bordering Puget Sound and the Olympic Peninsula.

To facilitate the creation of these autonomous regions, the bill establishes a joint legislative task force, chaired by the lieutenant governor, which will develop a plan for the regions' formation. The task force will consist of key legislative leaders and will be responsible for selecting members for two committees—one for each region—composed of representatives from various sectors and interests within those regions. These committees will explore strategies for the regions' establishment and report their findings to the task force by December 31, 2026. The act is referred to as the "win-win for Washington act."
