Helping to Preserve, Promote, and Protect Our Open Space
The Conejo Open Space Foundation (COSF) is a 501(c)(3) nonprofit corporation formed in 1995 to promote, support and help maintain the open space and trail system of the Conejo Valley, and to educate visitors as to their roles as custodians and protectors of the open space and the environment. We support and help fund ongoing programs sponsored by the Conejo Open Space Conservation Agency (COSCA). We are funded through individual, business, and corporate memberships, donations and grants. Funds received by COSF are highly leveraged through the extensive use of unpaid community volunteers and other in-kind donations.
