Growth Management Act.

The Growth Management Act (GMA) is the comprehensive land use planning framework for counties and cities in Washington.  Originally enacted in 1990 and 1991, the GMA establishes land use designation and environmental protection requirements for all Washington counties and cities.  The GMA also establishes a significantly wider array of planning duties for 28 counties, and the cities within those counties, that are obligated to satisfy all planning requirements of the GMA.  These jurisdictions are sometimes referred to as "fully planning" under the GMA.

All jurisdictions are required by the GMA to satisfy specific designation mandates for natural resource lands and critical areas.  In addition to requirements for natural resource lands, all local governments must designate and protect environmentally sensitive critical areas.  These protection requirements obligate local governments to adopt development regulations, also known as critical areas ordinances (CAOs), that meet specified criteria.  As defined by statute, critical areas include:  wetlands; aquifer recharge areas; fish and wildlife habitat conservation areas; frequently flooded areas; and geologically hazardous areas.

Growth Management Act—Voluntary Stewardship Program.

The Voluntary Stewardship Program (VSP) was created in 2011 and allows participating counties to develop local work plans that use voluntary and incentive-based tools, as an alternative to regulation, to protect critical areas and agricultural lands. Counties had to opt in to the VSP by early 2012, and 27 counties chose to participate.

Counties participating in the VSP create a work plan that is approved by the Washington State Conservation Commission (Conservation Commission) and then implement the plan by recruiting local landowners to participate in incentive-based stewardship activities.  Counties report their progress to the Conservation Commission.  The Conservation Commission is required to determine every two years which watersheds in participating counties received adequate funding to implement the VSP.

If the Conservation Commission determines that a watershed within a participating county has not received adequate funding to implement the VSP, the county must take one of four specified actions:

• develop, adopt, and implement a work plan in the watershed that protects critical areas used for agricultural activities;
• adopt development regulations that have previously been adopted by another local government for the purpose of protecting critical areas used for agricultural activities;
• adopt development regulations certified by the Department of Commerce as protective of critical areas in areas used for agricultural activities; or
• review, and if necessary, update development regulations adopted under the GMA to protect critical areas as they relate to agricultural activities.

Washington State Conservation Commission.

The Conservation Commission assists and guides Washington's 47 conservation districts, which are political subdivisions of the state, as they work with local communities to conserve renewable natural resources.

The date to join the Voluntary Stewardship Program is changed from January 2012 to July 1, 2024.
