Growth Management Act

The Washington Growth Management Act (GMA), first adopted in 1990 as a series of statutes developed to address ways to accommodate growth, requires the fastest-growing cities and counties to complete comprehensive plans and development regulations to guide future growth. Under the GMA, every county and city in the state is required to conduct a thorough periodic update of its comprehensive plan to bring it up to date with any relevant changes in the GMA, recent case law, and to respond to changes in land use and population growth.

Spokane’s next periodic update is due in 2026.
