Washington State Growth Management Act

The Washington State Growth Management Act is a state law that requires state and local governments to manage Washington’s growth by identifying and protecting critical areas and natural resource lands, designating urban growth areas, preparing comprehensive plans and implementing them through capital investments and development regulations. This approach to growth management is unique among states. Known as the GMA, the Act (Chapter 36.70A RCW) was adopted by the Legislature in 1990.

The GMA was adopted because the Washington State Legislature found that uncoordinated and unplanned growth posed a threat to the environment, sustainable economic development and the quality of life in Washington.

Rather than centralize planning and decision-making at the state level, the GMA focuses on local control. The GMA establishes state goals, set deadlines for compliance, offers direction on how to prepare local comprehensive plans and regulations and sets forth requirements for early and continuous public participation. Within the framework provided by the mandates of the Act, local governments have many choices regarding the specific content of comprehensive plans and implementing development regulations.

The Growth Management Hearings Board hears and determines allegations that a government agency has not complied with the GMA or the related Shoreline Management Act (SMA, Chapter 90.58 RCW). A 1991 law amended the GMA to create three regional boards, but a 2010 law consolidated them into one. SMA jurisdiction was added in 1996. The board's administrative rules of practice and procedure are found in the Washington Administrative Code (Title 242-02 WAC).
