Concerning county comprehensive plans and development regulations.

This bill requires Washington counties and cities to regularly review and update their community land use plans and development regulations to align with state requirements. Small cities (population under 500, not near large cities, with low growth) can opt out of full reviews but must still update critical areas protections and transportation plans. Counties must also review urban growth areas to ensure they accommodate projected development over 20 years while maintaining environmental safeguards. The law mandates public input processes for all changes and sets specific deadlines for updates, with penalties for noncompliance. It directly affects local governments, developers, and residents by standardizing land use planning across the state.
