The requirements set forth in this chapter shall be considered minimum for planned developments.

A.

In the case of a project consisting of a group of two or more buildings to be constructed on a plot of ground not subdivided into the customary streets and lots and which will not be so subdivided, or where the existing or contemplated street and lot layout make it impractible to apply the requirements of this title to the individual building units in such project, the applying of such requirements to such project shall be done by the board of appeals in a manner that will ensure substantially the same character occupancy, maximum intensity of use, and minimum standard of open spaces as permitted by this title in the district in which the proposed project is to be located.

B.

In no case shall the board authorize a building coverage exceeding that which would be obtained were the same area to be developed by the customary subdivision thereof into streets and lots in conformance with the adopted subdivision regulations, and by the type of buildings customary in the district and in compliance with the requirements of this title. The board shall not authorize the erection of a project on a parcel of ground occupied by another principal structure.

A residence development project consisting of any number of buildings, the contemplated arrangement of which makes it impossible to apply the requirements of this title to the individual buildings, may be authorized by the board of appeals in districts in which such projects are permitted under this title. In so doing, the board shall first hold a public hearing to consider the plans for such project and shall determine whether the plans for such project meet the following conditions:

A.

The tract of land on which the project is to be erected meets minimum size requirements as specified in Section 17.40.040.

B.

The buildings are to be used only for residential purposes and the customary accessory uses, such as private garages, storage spaces, recreational and community activities.

C.

The average lot area per family or dwelling unit on the site, exclusive of the area occupied by drives or streets, will not be less than ninety percent of the lot area per family required in the district in which the project is to be located.

D.

There is to be provided within the tract, or immediately adjacent thereto, parking spaces in private garages or off-street parking areas as specified in Section 17.48.010.

E.

There are to be provided, as a part of the project, adequate recreation areas to serve the need of the anticipated population to be housed therein.

F.

Drives, accessways and parking areas are developed to a standard equal to that required for public use.

G.

Such drives and accessways are protected by recorded deed covenants assuring their availability to all residents of the project.

H.

The proposed project will constitute a residential environment of a sustained desirability and stability; it will be in harmony with the character of the surrounding neighborhood and ensure substantially the same type of occupancy as obtained or may be expected to be obtained in said neighborhood; it will result in intensity of land utilization no higher, and standards of open spaces at least as high as permitted or specified in the chapter which applies to the district in which the project is to be located.

I.

The project will be consistent with the intent and purpose of this title to promote public health, safety, and general welfare.

Height, yards, and lot coverage shall be regulated by the following schedule and in no case shall the board authorize standards less than:

A.

The board of appeals shall consider the conditions set forth in Section 17.40.040 when considering any changes in an approved plan.

B.

The board of appeals shall approve or disapprove any plan or revision of an approved plan within sixty days of the filing of all elements of the plan.
