Open Space


The Alta Vista Open Space is located adjacent to the Dos Vientos Open Space in Newbury Park. Most of this 43-acre area is owned by a homeowners association, although about 11 acres, located on the south side of Calle Alta Vista, is owned by COSCA. The predominant habitat on-site is coastal sage scrub.

COSCA is a joint powers agency between the City of Thousand Oaks and Conejo Recreation and Park District
