Aliso Viejo

Aliso Viejo was originally part of the 22,000 acre Moulton Ranch. The Moulton family took title in the 1890's to land originally granted to Juan Avila by the Mexican government in 1842. In 1976, Mission Viejo Company purchased the last 6,600 acres for a new planned community that is now part of the City of Aliso Viejo.

Aliso Viejo became Orange County 's 34th city on July 1, 2001. The first planned community in Orange County. By 2000, the population expanded by 32,000 residents, making it the top city in population growth in Orange County. Designed to make it possible to live, work and play in the same community, Aliso Viejo, today continues to grow and prosper.
