Who We Are

Who We Are

Friends of Cabin John Creek, Inc. (FoCJC) is a volunteer citizen group dedicated to the restoration, preservation, and stewardship of the Cabin John Creek watershed.  FoCJC was started informally in 1999 as a committee of the Cabin John Citizens Association in Cabin John, Maryland.  FoCJC has since incorporated as a 501(c)3 non-profit and has grown to include members from within and without the watershed, including residents of Glen Echo, Bethesda, Potomac, and Rockville.


FoCJC regularly collaborates with local organizations including the Montgomery County Department of Environmental Protection, City of Rockville, Maryland National Capital Park and Planning Commission, The Potomac Conservancy, Audubon Naturalist Society, Alice Ferguson Foundation, and Izaak Walton League of America.  FoCJC volunteers organize events and programs, such as Creek Clean-ups, environmental film viewings,  stormwater management campaigns, and other activities to educate and motivate local residents to become stewards of Cabin John Creek.

Mission Statement
We work to protect and improve the health and beauty of the Cabin John Creek Watershed, raise awareness of its significance in the community, and foster community involvement in these goals through education, projects, and advocacy.
Board of Directors

Friends of Cabin John Creek is always looking for talented go-getters who love working for a good cause, sharing their knowledge and experience, and learning new skills.  Volunteering with FoCJC -- whether as an intern, event supporter, program organizer, or board member -- allows you to learn more about the challenges and threats facing our watershed and make a difference for the environment.  There are opportunities for people with all backgrounds and availability.  Contact us to find out more!

Our Logo

FOCJC has chosen the Cabin John Bridge as a symbol in the FOCJC logo, because the historic Cabin John Bridge (built in 1863) is located at the geographic point where all the water of the Cabin John Creek Watershed flows into the Potomac River.
