The purposes of these regulations are to encourage the appropriate development of tracts of land sufficiently large to allow comprehensive planning, and to provide flexibility in the application of certain regulations in a manner consistent with the general provisions of the zoning regulations, thereby promoting a harmonious variety of uses, the economy of shared service and facilities, compatibility of surrounding areas, and the creation of attractive, healthful, efficient and stable environments for living, shopping or working.
It is further purpose of this section:
A. 
To take advantage of advances in technology, architectural design, functional land use design;
B. 
To recognize the problems of population density, distribution and circulation, and to allow a deviation from rigid established patterns of land uses, but controlled by defined policies and objectives;
C. 
To produce a comprehensive development equal to or better than that resulting from traditional lot by lot land use development;
D. 
To permit flexibility of design in the placement and uses of buildings and open spaces, circulation facilities and off-street parking areas, and to more efficiently utilize potentials of sites characterized by special features of geography, topography, size or shape;
E. 
To permit flexibility in height of buildings but still requiring a development to maintain a ratio of site area to dwelling units that will be in harmony with the area in which the proposed development is to be located.
(Formerly 20.68.230; Ord. 485 § 11.08, 1971; Ord. 1505 § 12, 2001)
The following developments referred to in this section are permitted only upon the granting of a planned unit development permit as outlined in PMC § 20.69.300. Other large, integrated developments are permitted without such a permit, but shall be subject to all regulations generally applying in the district in which they are located.
(Formerly 20.68.240; Ord. 485 § 11.08.01, 1971; Ord. 1505 § 12, 2001)
Planned residential developments may be established in residential districts on parcels of land which are suitable for and of sufficient size to be planned and developed in a manner consistent with the purposes and objectives of PMC § 20.69.030 through § 20.69.080. For those planned unit developments which are located in the RS districts, the site shall include not less than 10 acres of contiguous land, unless the city finds that the property of less than 10 acres be suitable by virtue of its unique historical character, topography, or other natural features, or by virtue of its qualifying as an isolated problem area.
(Formerly 20.68.250; Ord. 485 § 11.08.02 (A)1, 1971; Ord. 1505 § 12, 2001)

In projects exclusively residential (multifamily or single-family), the land characteristics and development plans shall be such that:
A. 
The development can be essentially independent and contained, physically disassociated from surrounding properties by topography or existing woods or other means, and by its direction of orientation. Such insulation should effectively protect the project from existing or future surrounding development and effectively protect existing or future surrounding development from being affected by the project. Under such conditions maximum variations in concept, design, density, or zoning adjustments may be permitted.
B. 
All residential projects may propose concepts such as:
1. 
Four-unit dwelling clusters with party walls and one side and one front yard for each unit;
2.
