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.
COSCA was created in 1977 by a joint powers agreement between the City of Thousand Oaks and the Conejo Recreation and Park District, in order to coordinate land use planning and policy decisions, and facilitate open space acquisition, management, and conservation according to the goals identified in the City’s General Plan.
There are nearly 15,250 acres of protected open space within Thousand Oaks' city limits and planning area. 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.
To acquire, conserve, and manage open space within and surrounding the Conejo Valley for future generations, sustainably balancing public use with ecosystem protection.
The Conejo Open Space Conservation Agency will permanently conserve a system of natural open space and multi-use trails within and around the Conejo Valley to steward natural and cultural resources, preserve native habitats, provide opportunities for public enjoyment through trail-based recreation and outdoor education, and visually enhance the community.
