purchased the last 6,600 acres for a new
planned community that is now part of the
City of Aliso Viejo. The first residential
units were offered in March of 1982 and
the first residents arrived in November
of the same year.

lists and lotteries held for singles and
couples anxious to be a part of the community.

residents, making it the top
city in population growth in Orange County.
