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. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08, 1971. Formerly 20.68.230).

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. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.01, 1971. Formerly 20.68.240).

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. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.02 (A)1, 1971. Formerly 20.68.250).

Planned commercial developments may be established in commercial districts on parcels of land which are suitable for and of sufficient size to plan and develop them and that are consistent with the purposes and objectives of PMC 20.69.030 through 20.69.080. Planned commercial developments shall be subject to the standards and requirements contained in PMC 20.69.030 through 20.69.080 and may be authorized in conjunction with a request for reclassification, provided that the applicant agrees in writing to the terms and conditions contained herein, and provided further that the reclassification is consistent with the comprehensive plan. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.02(A)2, 1971. Formerly 20.68.260).

Combination commercial and residential developments shall be established in residential and commercial zones on parcels of land which are suitable for and of sufficient size to be planned and developed in a manner consistent with the purpose and objectives of PMC 20.69.030 through 20.69.080. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.02(A)3, 1971. Formerly 20.68.270).

Planned industrial developments may be established in any industrial district 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. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.02(A)4, 1971. Formerly 20.68.280).

Repealed by Ord. 1505. (Ord. 485 § 11.08.02(B), 1971. Formerly 20.68.290).

The following buildings and uses are permitted as hereinafter specifically provided and/or referred to in other chapters. The buildings and uses may be permitted either singly or in combination, although the combination may require a zoning classification change.

A. In all residential developments or in combination residential-commercial developments, 30 percent of the entire site area shall be devoted to outdoor living area and shall be in common or shared outdoor living area.

B. Outdoor living area required by this section may, at the discretion of the city, be dedicated to the city, as either rights in fee or easement, without jeopardizing the density or other development standards of the proposed development, provided the size and amount of the proposed dedication meets the criteria of the city for neighborhood parks built to A.D.A. standards. The square footage of land dedicated for public parks shall be deemed a part of the development site for the purpose of computing coverage density. The purpose of this section is to provide adequate light, air, open space, and recreational facilities to occupants of such development. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.03(B), 1971. Formerly 20.68.330).

A. That portion of the development adjoining single-family zoning shall require perimeter project development of single lots and detached single-family houses meeting the regulations of the adjoining zoning.

B. That portion of the development adjoining multifamily zoning shall require perimeter project development of density, building height and size, yard spaces, similar to the regulations of the adjoining zoning.

C. That portion of the development site where protection of scenic vistas is desirable shall require height regulations to prevent encroachments, which would occur with conventional RS or RMH district development. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.03(C), 1971. Formerly 20.68.340).

In any development which is primarily designed for or occupied by dwellings (including commercial/residential developments), all electric and telephone facilities, fire alarm conduits, street light wiring, and other wiring, conduit and similar facilities shall be placed underground by the developer, unless waived by the city. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.03(D), 1971. Formerly 20.68.350).

The development shall be allowed an increase in density of not to exceed 10 percent over the regulations of the parent zone in which the development is located, except as more restrictive regulations may be prescribed as a condition of approval of a planned unit development permit pursuant to PMC 20.69.300. The total average residential density of the project will be compatible with the comprehensive plan. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.03(E), 1971. Formerly 20.68.360).

Projects of 10 acres or more which funnel traffic to a principal access point shall connect at that point to a through-circulation major residential or higher-traffic capacity street. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.03(F), 1971. Formerly 20.68.370).

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. Town or row houses with party side walls;

3. Double row houses with party side and rear walls;

4. Condominium ownership in multifamily buildings;

A. Limit the floor area of nonresidential uses to one-half of one percent of the gross land area of the development.

B. Limit nonresidential uses to those business facilities which can be related in size and service principally to the project, such as grocery, delicatessen, drugs, and specialty shops such as sports, arts, antiques, or professional offices, such as doctors (clinics), architects, lawyers, and the project administration offices. Such uses should be in ground floor locations and in buildings comparable in size, in character with, and of similar architectural style as the single-family buildings in the project. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.05(C), 1971. Formerly 20.68.420).

Except as otherwise provided in PMC 20.69.090 through 20.69.160, the minimum lot area, width, and frontage, height and yard requirements otherwise applying in the district shall not dictate the strict guidelines for development of the planned unit development but shall serve to inform the designers of the importance of developing a project that will be in harmony with the character of the surrounding neighborhood. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.07, 1971. Formerly 20.68.450).

The city may, as a condition of approval for any development for which a permit is required by PMC 20.69.020, require that portions of the tract or tracts under consideration be set aside, improved, conveyed or dedicated for the uses described in PMC 20.69.250 through 20.69.280.

Whenever private outdoor living area is provided, the city shall require that an association of owners or tenants be created into a nonprofit corporation under the laws of the state which shall adopt such articles of incorporation and bylaws and adopt and impose such declaration of covenants and restrictions on such outdoor living areas and/or common areas that are acceptable to the city. The association shall be formed and continued for the purpose of maintaining such outdoor living area. Such an association, if required, may undertake other functions. It shall be created in such a manner that owners of property shall automatically be members and shall be subject to assessments levied to maintain the outdoor living area for the purposes intended. The period of existence of such association shall be not less than 20 years, and it shall continue thereafter and until majority vote of the members shall terminate it. (Ord. 1505 § 12, 2001; Ord. 485 § 11.08.08(B), 1971. Formerly 20.68.480).
