19.50.010   Purpose, applicability.
   This chapter regulates development and new land uses in the special purpose zoning districts established by Section 19.40.010. The purposes of the individual special purpose zoning districts and the manner in which they are applied are as follows.
   A.   SPA (Special Planning Area). The SPA district is applied to areas appropriate for significant new growth subject to comprehensive planning and which are indicated on the General Plan Land Use diagram as Special Planning Areas. Horizontal or vertical mixed-use is required in all areas designated SPA (except for the Bell-Muir SPA). Development within each SPA is intended to be consistent with the General Plan conceptual land use plan and General Plan policies applicable to each SPA.
   B.   PQ (Public/Quasi Public Facilities) District. The PQ zoning district is applied to areas appropriate for the wide range of public, institutional, and auxiliary uses that are established in response to the health, safety, cultural, and welfare needs of the City. The PQ zoning district is primarily intended to implement the Public Facilities and Services land use designation of the General Plan.
   C.   OS1 (Primary Open Space) District. The OS1 zoning district is applied to areas appropriate for permanent protection as open space because of environmental resources or potential hazards. These areas may include the Resource Constraint Overlay Areas of the General Plan and other sensitive habitats, oak and riparian woodlands, wetlands, creekways, riparian corridors, groundwater recharge areas, power transmission corridors, deer herd ranges, hillsides and viewshed management areas, and areas subject to flooding, that are either, publicly owned or have been committed to preservation by property owners in conjunction with development approval. The OS1 zoning district is primarily intended to implement the Primary Open Space land use designation of the General Plan.
   D.   OS2 (Secondary Open Space) District. The OS2 zoning district is applied to areas appropriate for both intensive and non-intensive recreational activities, such as parks, lakes, golf courses, trails, resource management, detention basins, agriculture, grasslands and other similar uses. The OS2 zoning district is primarily intended to implement the Secondary Open Space land use designation of the General Plan.
