green City Days

Giving back to our city parks and green spaces


We’re celebrating 17 years of outstanding service and dedication to Washington’s forested parks, natural areas and communities.

Green City Partnerships restore and care for our urban parks and forests. They empower people to be agents of change in their neighborhoods, help conserve open space and enhance community resilience in the face of climate change. In turn, these spaces provide safe access to nature, clean air and a habitat for plants and animals to thrive.


Green City Days are the annual celebration and kick-off to fall planting season.

Whether you are a first-time volunteer or long-time steward, these events are a great way to get involved and support your local community.

These unique partnerships bring together thousands of community volunteers, local governments, nonprofits, businesses and Forterra to create a sustainable network of natural areas throughout the region.

When you attend a Green City Days Event, each one is different. However, here’s what you can expect:


  • No experience is necessary, we will train you when you arrive.
  • All events are hands-on and everyone is welcome to sign up.
  • We will provide all the tools, including shovels, loppers and gloves.
  • Activities include planting young trees and plants, removing non-endemic and noxious weeds (blackberries and ivy) and more.
