A variety of policies are in place to guide Midpen and users of open space lands.

Definition and Philosophy

Open space is defined as land or water area that either remains in its natural state or is used for agriculture or otherwise essentially undeveloped. Open space provides protection for areas of particular scenic beauty and enhances the survival prospects for endangered plant and animal species. It enhances public safety through the minimization of flood erosion, landslide, earthquake and fire hazards. It provides room for production of food. It can help shape urban growth and thus provide a more liveable and efficient urban environment. In short, open space means "room to breathe."

Governing Policies

In 1999, the Board of Directors developed a Basic Policy to guide Midpen and provide information to the public about the mission, purpose, strategic direction and major elements of our operations. Midpen is currently in the process of reviewing and updating the Basic Policy. For further information, please call 650-691-1200 or email

Good Neighbor Policy

The Board of Directors and staff are strongly committed to establishing and maintaining good relationships with all of our residents and neighbors. The Board adopted Midpen's revised Good Neighbor Policy on September 26, 2007. Midpen is currently in the process of reviewing and updating the Good Neighbor Policy. For further information, please call 650-691-1200 or email

Resource Management Policies

Resource Management Policies guide the management of land to protect plants, animals, water, soil, terrain, geologic formations, historic resources, scenic features and cultural resources on Midpen owned and/or managed lands. RMPs are used to help guide the overall planning, budgeting and decision-making processes for programs and individual preserves.

Preserve Regulations, Safety and Etiquette

Visitors are responsible for knowing and obeying all rules and regulations before visiting the preserves.

District rules are designed to protect visitors and natural resources, and to help make everyone's visit a safe and enjoyable experience. Please observe District Regulations and Ordinances for your safety and enjoyment, as well as the safety and enjoyment of others.
