SOLVE has moved offices! As of August 1, 2022, our new address is 1501 SW Jefferson St. Portland, OR 97201

What We Do

SOLVE's hands-on projects are the perfect way to enjoy the outdoors while making a difference! Get involved by signing up for a local litter cleanup, invasive plant removal project, or native planting event near you.

To learn more about the importance of these projects and why we pick up trash, plant native trees and shrubs, and remove invasive plants, take a look at our educational resources.

Our volunteer projects are community-led and are available throughout Oregon, year-round.
