About the Open Space Plan

The King County Open Space Plan: Parks, Trails, and Natural Areas (Open Space Plan) is a functional plan of the King County Comprehensive Plan. Updated every six years, it provides the policy framework for how the county plans, develops, manages, and expands its complex system of 205 parks, 175 miles of regional trails, and 32,000 acres of open space. The Open Space Plan also enables King County to be eligible for certain federal and state grants, such as from the state Recreation and Conservation Office. This plan must be adopted by the King County Council.
