It is one of California’s largest urban regional open space districts, serving parts of San Mateo and Santa Clara counties and a small portion of Santa Cruz county. Midpen's mission is to acquire and preserve a regional greenbelt of open space and agricultural land of regional significance in perpetuity, protect and restore the natural environment and provide opportunities for ecologically-sensitive public enjoyment and education.
