Thank you for your interest in leading a volunteer project with SOLVE!

SOLVE supports projects across Oregon that engage volunteers and focus on one of three main activities:

  • Litter Cleanup
  • Invasive Plant Removal
  • Native Tree & Shrub Planting

Lead your event any time of year through our Project Oregon or Oregon Adopt-a-River programs. Or join hundreds of other projects statewide during the Oregon Spring Cleanup in April or the Beach & Riverside Cleanup in September. 

As a SOLVE Event Leader, you'll be able to post your volunteer opportunity to our events calendar, receive volunteer recruitment support, order free cleanup supplies or have access to our tool library (Portland metro only) see who has signed up for your project, and record your results through your Event Leader portal. Every successful project begins with a vision and effective planning. Become a community leader by becoming a SOLVE Leader today.

Please allow a minimum of three weeks to plan your event.
