In its 60 years of existence, Citizens Coordinate for Century 3 (C-3) has worked with its all-volunteer Board of Directors and members to promote principles of good design and planning to achieve a healthy environment, strong economy, and social progress in the San Diego/Tijuana region. Founded by Esther Scott and visionary architect, Lloyd Ruocco in 1961, with the support of Hamilton Marston and Ellen Revelle, C-3’s objectives were to conserve and promote "a handsome & functional community" through research, education, and coordinated citizen action. 

C-3’s rich history of advocacy and civic participation in the San Diego region include advocating to stop the expansion of Highway 163, expanding public park space on the waterfront, and protecting County environmental lands from encroaching development. 

C-3's strategy for preserving its own legacy and ensuring its future is founded on its commitment to membership, partnership, and visibility. C-3's members are among the most informed and influential citizens in the region, and this organization is committed to supporting and strengthening its membership by directly engaging members in its important work. C-3 also knows it can't do it alone and works closely in partnership with other organizations aligned with its mission.
