Launched in 2013, the King County Parks Foundation is focused on:

The King County Parks Foundation is devoted to cultivating private-sector philanthropy in order to connect communities to regional trails, parks, and open space and to support the resiliency of King County’s parks and trails for future generations. The King County Parks Foundation is a component fund at Seattle Foundation and as a public charity, a Section 501(c)(3) organization, all donations are tax-deductible to the extent allowed by law.

1 Million Trees

With your help, we are helping supply trees to King County and its partners who are striving to plant 1 million trees by 2022 across the county. We invite you to join the 1 Million Trees effort. Whether you volunteer, donate, or plant a tree, everyone has the opportunity to make a difference.

Trees help remove carbon pollution and contribute to clean air and water, healthy habitat for salmon and other wildlife, and create more livable communities.

1 Million Trees is part of King County’s Strategic Climate Action Plan to reduce carbon pollution and prepare for climate impacts.

Eastside Rail Corridor

The King County Parks Foundation is a key supporter of the development of the Eastside Rail Corridor Trail. This 16.7 miles of new regional trail will connect the Eastside like never before and provide the cities of Renton, Bellevue, Kirkland, Woodinville, and Redmond with new ways for non-motorized recreation and transportation.

Once completed, this corridor will greatly expand our transportation options, create economic and cultural opportunities, protect open space and natural resources, maintain public access to scenic vistas, and provide more ways to enjoy our beautiful region.

The King County Parks Foundation is helping secure financial support from the region’s business community to build this critical trail connection.

Land Conservation Initiative

King County is working with cities to launch an initiative that will conserve more than 62,000 acres of the highest conservation value lands and to do so within a generation (i.e. 30 years). These lands include urban parks, trails, farmlands, forest lands, and natural areas.

King County is one of the fastest growing large counties in the U.S. More than 2 million people call King County home today, with another 1 million expected by 2040.

The King County Parks Foundation believes that we, as the people who live, work, and play here, must act quickly to protect our most important remaining lands before prices further escalate and we lose conservation opportunities to development.

The King County Parks Foundation is providing civic and business guidance to King County to help secure funding for this initiative.
