Open Space Plan - 2010 Update

The 2010 King County Open Space Plan: Parks, Trails, and Natural Areas (Open Space Plan), a functional plan of the King County Comprehensive Plan, provides the policy framework for the county’s acquisition, development, stewardship, management, and funding of its open space system.

The Open Space Plan was adopted by the King County Council on June 14, 2010. Read the press release and see the SEPA Notice of Action.

The Open Space Plan is informed by the planning efforts and public processes of previous documents, such as the Parks Business Transition Plan (2002), The Regional Trails Inventory and Implementation Guidelines (2004), the Parks Futures Task Force Report (2007), the King County Comprehensive Plan (2008), and the 2009 King County Community Survey (pdf).

The 2010 updates reflect the many changes the the Parks and Recreation Division has undergone in recent years and confirms the agency's mission and goals for providing and stewarding the regional active and passive parks, trails, natural area parks, local rural parks, and forest lands that comprise King County's 26,000-acre system. This policy matrix helps explain what specific changes have been made to policies and why.

The plan was last revised in 2004 and enables King County to be eligible for certain federal and state grants, such as from the state Recreation and Conservation Office. To retain eligibility, the current update must be adopted by King County Council.

Printed copies of the final plan can be obtained by or calling 206-296-8687 and electronic copies can be downloaded in full or in parts from the links in the upper right column.
