Celebrate Earth Day with your neighbors and friends by volunteering to clean up your local park! Join this community-wide volunteer effort to make a difference. Earth Day Challenge Projects are held throughout the city. Volunteers may assist with trash pickup, raking, weeding, and removing sticks. We will supply gloves, garbage bags and rakes. Rakes at each park will be based on the number of volunteers participating. TO PICK UP SUPPLIES: Look for the Earth Day Challenge sign in each of the designated parks. No staff is onsite during the event.
