The Trinity Heights Neighborhood Association is a non-profit neighborhood association dedicated to

• Developing and promoting civic pride and involvement in the Trinity Heights neighborhood
• Actively working for the preservation and protection of the neighborhood by encouraging its maintenance and beautification
• Participating with other Durham neighborhood organizations for mutual enhancement and protection

Formed in 1985, the Association initiated efforts to have the City of Durham list the area as a local Historic district. Members of the Association were actively involved with Duke University in the design of the Trinity Heights Homesite development. Residents rallied to relocate the proposed town houses from Green Street to Markham Avenue and to save two historic trees in the area, thus preserving more open space.
