    1.0 BACKGROUND

    Stanford University's Santa Clara County General Use Permit (2000 GUP) requires the development of a "Special Conservation Plan" for the areas designated in the Stanford Community Plan as "Special Conservation Areas." Condition K.7 states:

    "within 12 months of approved of the General Use Permit, Stanford shall submit to the County Planning Office for approval a Special Conservation Plan in accordance with the requirements of the Community Plan."

    The Community Plan policies to be addressed by this conservation plan include:

    Description and Intent (SCP-LU 30) The Special Conservation Areas designation applies to lands south of Junipero Serra Boulevard which is deemed unsuitable for development due to natural resource constraints. Accordingly, no physical development other than that which supports conservation efforts may occur in these areas. It may include areas with the following environmental constraints:

    Steep or unstable slopes; Seismic or other geologic hazard zanes; Riparian areas extending 150 feet from the top of creek banks; and, Sensitive habitat areas, particularly for special status species.

    Allowable Uses (SCP-LU 31) The use of these areas is limited to conservation activities and habitat management, field environmental studies, and appropriate agricultural uses. Recreational use may be allowed if it is consistent with the particular environmental constraints of the area. Access for recreational use may be restricted.

    Development Policies (SCP-LU 32) No new permanent development in the form of buildings or structures is allowed, other than construction, modification, and maintenance of improvements to support conservation efforts. Existing non-conforming uses are allowed to remain, in accordance with the County's requirernents for non-conforming structures.

    SCP-LU 33 Stanford shall prepare a Special Conservation Plan for the Special Conservation areas. The Special Conservation Plan shall be submitted to the County Planning Office for approval. The plan will provide management guidelines addressing the following goals:

    Habitat management iiitlzin the areas for 25 years; Control of invasive, non-native species; Control of erosion; Avoidance ~f undisru rbed areas; Public safety; Appropriate access; and Minimization of human-caused impacts.

    The plan will contain measures specific to California tiger salamander, red-legged frog, and steelhead habitat; riparian habitat; and geologic and seismic hazard areas. The plan will consider such activities as resource conservation, construction of facilities to support conservation activities, access, vegetation management, and best management practices for Stanford lessees located in Special Conservation Areas.

    Stanford proposes to meet this requirement using an adaptive management approach that begins with the set of programs and guidelines described below. Management of the Special Conservation Areas must be dynamic and flexible to adapt to changing conditions, new technologies and experience. It is anticipated that an adaptive management program will be more successful in conserving biodiversity over the long-term than a proscriptive plan.

    It should not be construed that conservation planning at Stanford is limited to topics and areas discussed in this document. The Special Conservation Areas at Stanford as defined by Santa Clara County are a portion of the areas where Stanford conducts conservation activities. If a comprehensive Habitat Management Plan (HCP) is adopted for lands including the SCAs, its guidelines for habitat management would supercede those provided below. It should also be noted that these Special Conservation Areas were not defined solely on the basis of biotic resources and that other considerations were incorporated; e.g. soil stability.

    The basic objectives of the Special Conservation Area (SCA) designation are to protect important biological, archaeological and hydrological resources and to prevent potentially hazardous conditions in areas of steep or unstable slopes. To meet these objectives and work within the existing land use constraints, Stanford will manage the SCAs for controlled multi-use with emphasis on conservation.

    In keeping with the University's mission to pursue excellence in teaching and research, Stanford will manage the SCAs as academic resources as well. The use of these areas for teaching and research activities has yielded important knowledge concerning the biological

    and cultural resources they contain. These academic activities are a critical element of the adaptive management strategies outlined below.

    In 1998, Stanford established the Foothills Working Group to address management and conservation goals in Stanford's lower foothills, which includes substantial portions of all four SCAs. This group includes representatives from the Center for Conservation Biology, Public Safety, Facilities Operations, Stanford Management Company, Planning Office, and Government and Community Relations. The Foothills Working Group interprets and oversees access and operational policies and the Foothills Reclamation Program. In the
