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

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

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

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. 

SOLVE offers free cleanup supplies and volunteer recruitment assistance to all SOLVE Event Leaders. Every successful project begins with a vision and effective planning. SOLVE equips Event Leaders with project planning assistance to assure that your event is the best it can be and will achieve your project goals. 

Volunteers in the Portland Metro area may be eligible to recieve a small grant to cover disposal costs. Learn more here. 

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

  • SOLVE is a non-political, non​-partisan organization and does not permit ​volunteers to use SOLVE​ events to engage in political activity, publicly express or otherwise promote their political beliefs, candidates or other causes that distract from SOLVE’s mission.
  • SOLVE will not support events where political or partisan materials, campaign literature, or merchandise are distributed or sold to participating volunteers.  
  • SOLVE prohibits the use of its name, logo, and brand to promote any third party without permission.
