This chapter provides regulations applicable to development and new land uses in the special purpose zoning districts established by Section 17.06.010 (Zoning Districts Established). The purposes of the individual special purpose zoning districts and the manner in which they are applied are as follows:
A. 
P (Institutional) Zone. The P-zoning district is applied to areas appropriate for a variety of public uses, including city hall, educational facilities, hospitals, libraries, police and fire, and other public agency facilities which may require appropriate buffering from adjacent residential designations. The P zoning district is consistent with the public/quasi public land use designation of the general plan; and
B. 
OS (Open Space) District. The OS zoning district is applied to appropriate areas to ensure the conservation and protection of natural resources, including earthquake fault zones, fire protection areas, flood plains, open space areas, steep slopes of fifty percent or more and other significant habitat areas identified in the conservation and open space element of the general plan. The OS zoning district is consistent with the open space land use designation of the general plan.
