CitySoil Farm is a teaching farm and native tree nursery that showcases sustainable farming and accessible, local food. CitySoil is managed through a 4-way partnership with the King County Wastewater Treatment Division, King Conservation District, DIRTCorps, and White Center Food Bank.

Recycled resources

Located on a previously unused 1.5-acre plot, CitySoil has transformed the vacant space into urban agriculture that is dedicated to environmental education and sustainable farming. Through this teaching farm, King County and its nonprofit partners hope to see a future where environmental education can lead to an increase in community participation and sustainable food systems. At CitySoil, we can take advantage of resources recycled from our waste system with recycled water and compost made from Loop® biosolids.

Environmental education

We provide venues for environmental education and demonstration, increasing public awareness of garden and agricultural uses of recycled water and biosolids. We also support university curriculum and student internships, and are developing relationships with high school and technical programs in South Seattle, Tukwila, Skyway, and Renton.

During summer we offer farm field trips for community groups of 10 to 25, age 4th grade to adult. Field trips will tour the farm site and complete a related farm work project. The field trip educational focus can be tailored to participant interest and includes water systems, water conservation, salmon-friendly/pesticide-free gardening, rain-gardens, and composting (and more!). For field trips that include a treatment plant tour or take place during the school year, see our educational programs page.

Equity and social justice

We are working to cultivate food gardeners and to increase outreach and services for our neighboring communities. The food grown at CitySoil is accessible to everyone: volunteers and students can harvest the food as they learn or tend to the farm, but most of the food is donated to the White Center Food bank for those in need.

Get involved

CitySoil Farm often needs volunteers for the growing season, from March to October. Here are ways you can get involved:

• Individual volunteers: Check our volunteer match page for current individual volunteer postings: https://www.volunteermatch.org/search/org675010.jsp
• Groups (such as businesses, community groups, scout trips): We often need big groups for projects!
