The semi-annual event started in 2005. Back then, volunteers found litter and trash along the trail and river. Now, that landscape has changed.
The group works to preserve native plants and wildlife. A board with historical information was vandalized earlier this year. Volunteers made it look brand new.
"My first year I was like a first grader. We came and weeded out the whole place, and then we put down ground cover and put rocks on top...Well, it's really nice seeing the before and after in pictures and seeing what a difference you're making," said ninth grader Viknesh Kasthuri.
Over $300 were donated to stock up on new plants.
