Growth Management Act WAC Update

Summary of the project


The Department of Commerce is reviewing and updating the administrative rules for the Growth Management Act (GMA).  We work with local governments to provide guidance on comprehensive plans and development regulations that affect cities and counties across Washington.  Effective implementation of the GMA supports strong, resilient, and equitable communities.

Growth Management Services will consider amendments to our administrative rules based on legislative changes, new case law, and the need to clarify any statutory requirements that the existing rules do not adequately address. Commerce plans to finalize rulemaking by March 15, 2023 so that local governments have clear guidance on how to implement GMA requirements before the next round of periodic updates to local plans and regulations. We completed our last major WAC update in 2010, along with other minor amendments in 2015 and 2017. 

The subject of possible rulemaking includes:

  • Chapter 365-196 WAC, Procedural Criteria for Adopting Comprehensive Plans and Development Regulations
  • Chapter 365-190 WAC, Minimum Guidelines to Classify Agricultural, Forest and Mineral Lands and Critical Areas
  • Chapter 365-195 WAC, Best Available Science
