17.26.010 - Chapter purpose.

The purpose of this chapter is to identify and provide reference to all special purpose districts within the city. Special purpose districts provide unique development regulations to subject property than may otherwise be granted through the application of any base zoning district provided by this title. These districts are consistent with and implement the city's general plan special planning land use designation as shown in Table 17.20.020-1 (Zoning districts). There are two special purpose zones in the city as follows:

A. Specific plan zoning districts.

B. Planned development zoning districts.

17.26.020 - Specific plan zoning districts.

A. Purpose of the specific plan zoning district. The purpose of the specific plan zoning district is to designate unique planning areas within the city for which the city council has adopted or requires adoption of a separate planning document (a specific plan) consistent with the general plan and state law. The contents, requirements, and adoption and amendment procedures for specific plans are listed in Section 17.10.130 (Specific plans).

B. Designation. Specific plan zoning districts shall be delineated on the zoning map in a manner similar to that of any other zoning district except that each specific plan-zoned area shall also bear a name, number, symbol, or other delineation, as determined by the city planner, which distinguishes it from other specific plan zones, base zoning districts, or overlay zones. The assignment of the specific plan zone designation serves to provide a reference to the corresponding specific plan zoning document adopted by ordinance of the city council. Applicable zoning regulations and standards applicable to the land area shall be provided in the specific plan document, and shall be adopted by reference in this title.

C. Allowed uses. Allowed uses within the specific plan area are those listed uses in the adopted specific plan document. A specific plan may reference the allowed use provisions of a concurrent base zoning district contained in this title; however, in the event that there are conflicts between the provisions of the specific plan and this title, the specific plan shall prevail.

D. Development standards. Development standards within the specific plan area are those standards listed in the adopted specific plan. A specific plan may reference the development standards of this title, in which case the standards of this title shall apply. Where a specific plan is silent regarding a city-wide standard (e.g., sign regulations), the city standard shall apply. Where a specific plan establishes unique standards that are in conflict with the standards of this title, the specific plan standards shall prevail.

17.26.030 - Planned development zoning districts.

A. Purpose of the planned development district. The purpose of the P-D district is to provide procedures for the consideration and regulation of areas suitable for proposed comprehensive development with detailed development plans and of those areas that require special planning to provide for appropriate planned development in harmony with their natural features and other environmental consideration. The contents, requirements, and adoption and amendment procedures for planned developments are listed in Section 17.10.120 (Planned development).

B. Designation. Planned development zoning districts shall be delineated on the zoning map in a manner similar to that of any other zoning district except that each planned development-zoned area shall also bear a name, number, symbol, or other delineation, as determined by the city planner, which distinguishes it from other planned developments, base zoning districts, or overlay zones. The assignment of the planned development zone designation serves to provide a reference to the corresponding planned development zoning document adopted by ordinance of the city council. Applicable zoning regulations and standards applicable to the land area shall be provided in the planned development document, and shall be adopted by reference in this title.

C. Planned development areas adopted by reference. The following planned development areas have been adopted as part of this title by reference and are so designated on the zoning map of the city:

  1. Ione Memorial District;

  2. Amador Water Agency: Ione Water Treatment Plant;

  3. Mule Creek State Prison, CDF Fire Training Facility, and Preston Youth Correctional Facility);

  4. Jose's Place (adopted 1987);

  5. Castle Oaks (adopted 1989, revised 2003, revised 2005); and

  6. Wildflower (adopted 2005).

D. Allowed uses. Allowed uses within a planned development area are those listed uses in the adopted master plan document or as conditionally approved as part of the rezoning to planned development. A planned development master plan may reference the allowed use provisions of a concurrent base zoning district contained in this title; however, in the event that there are conflicts between the provisions of the master plan and this title, the master plan shall prevail.

  1. When a master plan was not established as part of the establishment of a P-D zone (e.g., when a request for the zone change to P-D and for a use permit for all proposed developments was approved) and a use is proposed that was not covered in the previous approval, a conditional use permit shall be required for all subsequent development and uses or a master plan providing for a range of uses shall prepared and considered. The master plan shall be prepared consistent with the provisions of Section 17.10.120 (Planned development).

E. Development standards. Development standards within the planned development area are those standards listed in the adopted planned development master plan. A planned development may reference the development standards of this title, in which case the standards of this title shall apply. Where a planned development is silent regarding a city-wide standard (e.g., sign regulations), the city standard shall apply. Where a planned development establishes unique standards that are in conflict with the standards of this title, the planned development standards shall prevail. When a planned development does not establish development standards, the standards for the equivalent base zoning district shall apply as determined and formally interpreted by the city planner.
