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, look at Upcoming Volunteer Opportunities below for upcoming Sweep the Creek event , and at the full calendar of events. More events will be planned as Montgomery County lifts COVID restrictions.

Sweep the Creek: Pick up trash and recyclables. Perhaps your team will find the most unusual item of the day! Past “finds” include shopping carts, auto parts, basketballs, shoes, building materials, and an amazing number of plastic bottles.

To indicate your interest in an event, 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

  • Sweep the Creek for individuals and (smaller) groups in Sligo Creek – April 17 through May 2, 2021

    This spring, more than 400 volunteers came out to Sweep the Creek. FOSC Stewards supported these individual / smaller group Sweeps by giving out gloves, trash and recycling bags donated by the Parks Department.


    Thank you to everyone who help rid the Creek of litter. Less litter means fewer pollutants such as microplastics and healthier wildlife and people.

  • Weed Warriors – Spring 2021

    Due to public health guidelines, FOSC isn’t yet holding large group Weed Warrior events to pull invasive plants. Small group or individual Weed Warrior initiatives may be held periodically in certain sections. Events open to non-Weed Warriors will be posted in the Upcoming Events section of the Homepage and on the Calendar of Events.
