Marymoor Park outdoor concerts
Join a fun bunch of volunteers and listen to great music at Marymoor Park this summer by signing up to be a Concert Composter/Recycler. Help educate concert goers on recycling and composting, which in turn diverts concert waste from the landfill. FREE concert & FREE parking when you volunteer for a shift.

For more information go to our Marymoor Concert Recycling Crew page or contact Laurie Clinton.

Sign-up for volunteer announcements

Summer fun – litter to pick up, invasive weeds to remove, native plants to nurture AND a VIDEO to shoot!

Come volunteer to help improve King County's natural areas, parks and urban forests. Spend some time removing invasive weeds to help newly planted and established native trees and shrubs survive and thrive. Native trees and shrubs improve the area for wildlife and water quality; and the healthier they are, the better for all!

A very special one-time event is happening on July 15 where we will be shooting a video on ‘Volunteering in King County Parks’. Please come volunteer at the event and be a part of the video! (Info on event and who to contact in schedule below).

To join an event, please register with the volunteer coordinator listed after each event.

For any questions about the King County Parks Volunteer Program or to inquire about a custom volunteer event for your group, please contact Volunteer Program Manager, Laurie Clinton or via phone at, 206-477-6113.

Events are on Saturdays from 9 a.m. to 1 p.m. unless otherwise noted*
