Friends of Sligo Creek is a nonprofit community organization dedicated to protecting, improving, and appreciating the ecological health of Sligo Creek park and its surrounding watershed.

What FOSC does

Friends of Sligo Creek (FOSC) offers events year round in support and appreciation of Sligo Creek and adjacent parkland. Litter clean-up and invasive plant clear-out events are among the most popular FOSC activities in the spring, summer and fall. FOSC also sponsors guided outdoor explorations of different sections and aspects of Sligo Creek flora and fauna. A wide variety of indoor programs throughout the year educate neighbors and users of the park about Sligo Creek’s strengths and challenges. FOSC also monitors the creek, advocating for civic policies that will support a healthier Sligo.

FOSC invites you to visit the creek, volunteer at an upcoming event, attend a program, advocate for the Creek, and join FOSC.

    Ellsworth Drive Synthetic Turf Proposal

    The County Hearing Officer received public testimony and will make a recommendation to the County Executive; the County Executive will make a recommendation to the County Council; and the Council will vote on whether to approve the abandonment (transfer ownership from the public sector to the private developer) of part of Ellsworth Drive.

    This is an important issue for downtown Silver Spring. FOSC opposes roadway abandonment to allow installation of synthetic turf because of human health and environmental pollution impacts.
