FOSC Volunteer Opportunities

Volunteers are FOSC! Your energy, enthusiasm & skills accomplish FOSC’s many goals.

Together, you have taken out hundreds of pounds of trash from the creek and surrounding parkland in the past year during the twice yearly Sweep the Creek events. You’ve removed hundreds of bags of invasive vines and other plants – saving trees and allowing native plants to come up and spring ephemerals to bloom. You’ve reported pollution to the FOSC Water WatchDog program right when it happens to limit the damage. Your efforts have a huge impact on Sligo Creek and Park.

If you want to volunteer at an event: look at Upcoming Volunteer Opportunities below for the next Sweep the Creek event and at the full calendar of events which contains event details. More in-person events will be planned as Montgomery County lifts COVID restrictions.

To indicate your ongoing interest in an activity or to indicate other interests or expertise: please email the committee coordinator to offer your help. There is something for everyone.

As you walk the creek paths and trails, you can collect and remove litter and recyclables. Bring a trash bag and gloves and make a difference to the Creek!

Upcoming Volunteer Opportunities

  • Weed Warriors

    FOSC is holding small group Weed Warrior events to pull invasive plants, mostly Wed and Friday mornings. These events are open to non-Weed Warriors. Events are posted Calendar of Events page.


  • Sweep the Creek – April 23 through April 24, 2022

    This spring, join more than 400 volunteers at Sweep the Creek. FOSC Stewards will be giving out gloves, trash and recycling bags donated by the Parks Department. The locations and schedule is posted on the Sweep the Creek page. No pre-registration required! Students seeking SSL hours should bring their forms with them to the Sweep.

    Less litter means fewer pollutants such as microplastics entering the Anacostia River and the Chesapeake Bay, and healthier wildlife and people.
