The Growth Management Act Steering Committee (GMASC) is the governing body of the Growth Management Act Committee – a planning organization composed of cities, towns, and Skagit County.

A technical advisory committee provides advice to the GMASC and is composed of planning staffs from member jurisdictions.
The Skagit Council of Governments (SCOG) provide administrative and staff support, technical studies and other work as set forth in the annual work program through an interlocal agreement between SCOG and member jurisdictions of the Growth Management Act Committee.
