Who We Are

The Conejo Open Space Conservation Agency preserves, protects, and manages open space resources in the Conejo Valley.  COSCA's open space system is a refuge from urbanization.  It's a resource that appreciates in value for both people and wildlife as time goes on.  With your help, our open space system will continue to offer a safe, stable environment for all organisms, whose complex interactions combine to form valuable habitat and ecosystems.



There are nearly 15,250 acres of protected open space within Thousand Oaks' city limits.  COSCA currently owns and/or manages approximately 12,400 acres of that open space and maintains more than 150 miles of trails. COSCA's staff includes two full-time administrative staff and six rangers.


COSCA is governed by a Board of Directors comprised of two members of the CRPD Board of Directors, two members of the City Council, and one appointed member of the public.

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