The Dupont Circle Citizens Association (DCCA) is a nonprofit, all-volunteer organization that plays a crucial role in maintaining the vibrant and architecturally significant Dupont Circle neighborhood in Washington, DC. With a strong sense of community, DCCA strives to create a safe and diverse environment, enhance the beauty and cleanliness of the neighborhood, and preserve its historic character. DCCA actively works to keep the community clean by targeting areas that breed rats and other health hazards.

Through their educational program, Scoop, they urge dog owners to clean up after their pets in public spaces. The organization also values diversity, supporting efforts to protect cultural, economic, ethnic, sexual, and commercial diversity in the area. Preserving the neighborhood's green spaces is another priority for DCCA.

With their matching-fund tree-planting program, residents have planted dozens of trees in public areas, and tree boxes with historically compatible fencing are encouraged to protect trees. DCCA also takes pride in the architectural heritage of Dupont Circle, having played a role in securing historic district designation for much of the neighborhood. They organize annual house tours that showcase the architectural diversity and creativity of its residents.

In addition to these efforts, DCCA serves as a meeting place for residents to exchange information and foster a sense of community. With a focus on safety, DCCA collaborates with citizen patrols and local law enforcement to address concerns and ensure residents' well-being. The Dupont Circle Citizens Association is committed to preserving the residential character of the neighborhood and improving the quality of life for all its residents, businesses, and nonprofit organizations
