17.18.020 ZONING DISTRICTS.
   A.   Zoning districts are established in order to classify, regulate, restrict and segregate the uses of land and buildings; to regulate and restrict the height and bulk of buildings; to regulate the area of yards and other open spaces about buildings; and to regulate the density of population, classes of land use zoning districts are established.
   B.   The city is divided into zoning districts that are generally grouped into two (2) categories: A) base zoning districts, and B) special purpose zoning districts. These districts conform to and implement the city's general plan land use categories as described in Table 17.18.020-1. Subsequent chapters in this article identify allowed uses and requirements for planning entitlements, as well as development standards unique to each zoning district.
      1.   Base Zoning Districts. The base zoning district is the primary zoning district that applies to a property. Every parcel located outside of the specific plan area throughout the city has a base zoning district that establishes the primary type and intensity of land use for the parcel, along with development regulations for that particular type and intensity of land use for the parcel, along with development regulations for that particular type and intensity of land use. Base districts are grouped into five (5) categories as follows:
         a.   Residential zoning districts.
         b.   Rural zoning districts.
         c.   Commercial zoning districts.
         d.   Mixed use zoning districts.
         e.   Public, quasi-public, and recreational zoning districts.
      2.   Special purpose zoning districts. The special purpose zoning district either functions as the base zoning district or supplements the base zoning district and requires special project entitlement, which allows for flexibility from traditional development standards. There are two (2) special purpose zoning districts:
         a.   Specific plan zoning districts that require submittal for a specific plan document for proposed development that will replace the city's zoning regulations for the subject parcel(s). This designation is typically applied to larger land areas that warrant master planning.
         b.   Planned development zoning districts are limited to property zoned PD-Planned Development as of the effective date this title.
   C.   In the event of a conflict between the regulations of the base zoning district and the special purpose zoning district, the provisions of the special purpose zoning district shall apply.
