The RPD residential planned development district is intended for cluster housing under appropriate conditions. In addition thereto, it is the purpose the RPD district to provide for development which shall be open space and recreation oriented. It is recognized that owners of cluster housing units in the residential planned development will ordinarily not have available to themselves private open space areas and, therefore, must depend on the proper development of common open space areas. It is, therefore, one of the purposes of this district to insure any residential planned development the adequacy of available, usable common open space areas and the development and maintenance of such areas.

(Prior code § 1832)

Property in the RPD district may be used for:

A.

Any use permitted in the R-A-20 district;

B.

A planned residential development in accordance with the prescribed standards set forth in Section 17.18.040(B) and if a conditional use permit is obtained as provided in Chapter 17.68 of this code. Approval by the planning commission shall be based upon findings that the plan provides for adequate light and air, public safety and convenience, protection of property values in the neighborhood and preservation of the general welfare of the community. However, such conditional use permit shall not reduce or make less restrictive the minimum development standards.

(Prior code § 1833)

The following uses are expressly prohibited in the RPD district:

A.

Commercial uses, including home occupations as defined in Section 17.02.290, unless such home occupation meets the criteria set forth in Chapter 17.48 of this code;

B.

Industrial uses.

(Prior code § 1834)

A.

The property development standards for the R-A-20 district as set forth in Sections 17.06.060 through 17.06.330 shall apply, if property is used only for uses permitted by right in such district.

B.

The following minimum property development standards shall apply if property is used as provided in Section 17.18.020(B).

1.

Area. The proposed development plan shall include a parcel or parcels of land containing not less than ten acres.

The dwelling units and buildings and the land within the development may be divided in ownership only in the manner authorized in the approval of the development.

2.

Density. Project density for each residential planned development shall be consistent with the standards established in the land use element of the general plan. The total number of units permitted on a parcel or parcels of land shall be based on the density assigned to that parcel by the land use element and shall be so designated on the city's official zoning map. Each development shall comply with the other requirements of this section. In no case shall the density of any one-acre portion of any parcel or parcels developed for residential planned development use exceed twice the zoning density assigned to that parcel or parcels. The boundaries of each acre to be used in calculating the highest permitted density for that acre is subject to approval or modification by the planning commission in passing upon issuance of each conditional use permit. The developer shall submit to the city, as part of his application, a grid pattern superimposed on his site plan which sets out contiguous areas each of which is one acre in size. The longest side of each area shall not exceed twice the shorter side. This requirement is not intended to limit design flexibility of any proposed development.

No structure shall exceed a height of thirty-five feet or two stories.

4.

Open Space. Common and private open space shall comprise not less than seventy percent of the parcel. Common open space shall be that portion of the total land area developed for recreational purposes or landscaped for aesthetic purposes and designated for the use and enjoyment of all of the occupants of the development, but shall not include streets, highways or utility easements where the ground surface is not available or useful for open space yards, patios or other areas primarily designed to serve other functions. The applicant shall submit to the planning commission, and it shall be made a condition of approval, satisfactory evidence to assure continued retention of open space and for perpetual maintenance of common areas. In this connection, an offer of dedication of same will be required.

8.

Development Schedule. The planning commission shall require a progress schedule indicating the development of common open-space related to the construction of residential dwelling units, which will become a condition of approval. The planning commission may modify without a hearing this condition pertaining to the development schedule based upon a written affirmative showing of hardship.
