Title 18 — Zoning

Chapter 18.52 — RPD RESIDENTIAL PLANNED DEVELOPMENT ZONE

San Dimas Zoning Code · 2026-06 edition · updated 2026-07-06 · San Dimas

§ 18.52.010. Created.

There is created an RPD residential planned development overlay zone. Whenever it is placed on the official zoning map, the designation RPD shall be indicated after the zoning designation of the underlying zone. The standards of the RPD zone may take precedence over the standards of the underlying zone if the planning commission determines that the imposition of the RPD standards will result in an enhanced development which is in keeping with the intent and goals of the city's general plan. Permitted uses in the RPD zone shall be permitted in addition to the uses permitted in the underlying zone. The RPD zone shall not be overlaid over a principal zone other than S-F or SF-A.

(Ord. 37 § 242.1, 1961; Ord. 291, 1970; Ord. 355 § 1, 1971; Ord. 638 § 1, 1978; Ord. 1226 § 1, 2014)

§ 18.52.020. Purpose.

The purpose of the residential planned development zone is to promote residential amenities beyond those expected under a conventional development, to achieve greater flexibility in design, to encourage well-planned neighborhoods through creative and imaginative planning as a unit, and to provide for appropriate use of land which is sufficiently unique in its physical characteristics or other circumstances to warrant special methods of development. In implementing planned development, it is further declared that the purpose of this chapter is to reduce development problems in hillside areas and to preserve areas of natural scenic beauty through the encouragement of integrated planning, integrated design and unified control of development. This zone permits flexibility in site design and variety in development and further encourages the preservation of natural features in open space through innovative design and land planning.

(Ord. 37 § 242.2, 1961; Ord. 291, 1970; Ord. 355 § 1, 1971; Ord. 1226 § 1, 2014)

§ 18.52.030. Uses permitted.

  • A. Residential Uses. Any use permitted in the principal zone over which the RPD zone is placed is subject to all limitations and conditions of that zone.

  • B. Open Space Uses. Noncommercial parks, gardens, playgrounds, golf courses and other open space uses are permitted in the RPD zone. Various noncommercial facilities such as clubhouses, swimming pools, tennis courts and horticultural conservatories may be included in such open space uses.

  • C. Uses Permitted by Conditional Use Permit. If a conditional use permit has first been obtained as provided in Chapter 18.200 , property in the RPD zone may be used for a planned residential development subject to approval by the commission. Such approval by the commission shall be based upon findings that the plan complies with the purpose of planned residential development as set forth in Section 18.52.020 , provides as well or better for light and air, for public safety and convenience, the protection of property values and the preservation of general welfare of the community than if developed as provided in subsection A of this section, and shall be subject to all of the provisions of Section 18.52.020 .
