About COSCA

As the name implies, the Conejo Open Space Conservation Agency (COSCA) has been entrusted with the responsibility of preserving, protecting and managing open space resources in the Conejo Valley. The Conejo Valley is generally described by the City of Thousand Oaks Planning Area.

COSCA was created in 1977 by a joint powers agreement between the City of Thousand Oaks (www.toaks.org) and the Conejo Recreation and Park District (www.crpd.org), enabling the two agencies to "jointly exercise their legal powers to create a jurisdictional framework for the conservation of natural open space lands, assure coordination of local land use and resource management decisions and establish an entity to focus community resources toward achievement of adopted General Plan goals." In this context, "open space" is defined as land which is in essentially a natural, undeveloped state, and does not include golf courses, developed park sites or landscaped greenbelts.

COSCA currently owns or manages over 11,300 acres of open space and maintains more than 140 miles of trails. COSCA's staff includes two full-time administrative staff and six Rangers. For the rules and regulations that apply to COSCA open space, please click here (COSCA Ordinance No. 01-2009).

A Few Words...

By providing a refuge from urbanization for both people and wildlife, the open space system is an investment in the future. Unlike so many things in today's world, this is a resource which appreciates in value for both people and wildlife as the years go by. Hopefully, with your help, our open space system will continue to offer a safe, stable environment for all organisms, whose complex interactions combine to form viable ecosystems.
