(a) 
It is the intent of this division to encourage unified design of housing, commercial, industrial, or institutional areas and facilities, or combinations thereof, to provide for integrated developments having harmony of design and variety of function. It is not intended to permit a greater density or uses different from those set forth in the regulations of the district in which the development is located, but this division is to provide for greater flexibility in the design of buildings, yards, courts, and circulation, than would otherwise be possible through the strict application of district regulations, and to produce:
(1) 
A maximum choice in the types of environment and living units available to the public;
(2) 
Open space and recreation areas;
(3) 
A pattern of development which preserves trees, outstanding natural topography, and geologic features, and prevents soil erosion;
(4) 
A creative approach to the use of land and related physical development;
(5) 
An efficient use of land resulting in smaller networks of utilities and streets and lower housing costs;
(6) 
An environment of stable character in harmony with surrounding development; and
(7) 
A more desirable environment than would be possible through the strict application of other sections of this article.
(b) 
The planned unit development division is designed to provide for small-scale and large-scale developments incorporating a single type or a variety of residential and related uses which are planned and developed as a unit. Such a development may consist of individual lots or it may have common building sites. Common land must be an essential and major element of the plan which is related to and affects the long-term value of the homes and other development. A planned unit shall be a separate entity with a distinct character in harmony with surrounding development.
(2002 Code, sec. 54-241)
A planned unit development may be authorized, provided that all of the following provisions are complied with:
(1) 
A planned unit development shall be permitted in any district except an A general agricultural district, R-1 rural single-family district, R-2 single-family district, R-3 rural mobile home residential district, or an R-4 mobile home residential district.
(2) 
The proposed planned unit development shall be designed to provide for the unified development of the area and in accordance with the spirit and purposes of the district in which the unit is located. The design may provide for modification of yard, setback, and height requirements, but the use, density, intensity of use, and coverage requirements for the district, and the minimum dimensions established for the design of courts shall not be reduced.
(3) 
The minimum size of the site upon which a planned unit development shall be located shall be not less than three acres for commercial developments, not less than ten acres for residential developments, and not less than 40 acres for industrial, educational, medical, and other types of institutional developments.
(4) 
The off-street parking requirements set forth in division 5 of this article may be complied with by providing one or more permanent, common, off-street parking facilities for all uses within the development, provided that the facility contains the requisite number of spaces for each use, and that the spaces provided for permanent residents shall be clearly designated and separated from spaces provided for employees, customers, and service. The total spaces provided shall not be less than the sum of the individual requirements and the spaces required for each use, and shall be under the ownership or permanent control of the owners of the use for which the spaces are required.
(5) 
The developer shall submit a site development plan of the proposed development in support of the application for a planned unit development permit. This application shall be considered the same as a rezoning request and the same procedures shall be followed concerning application, planning commission review, and public hearings. Upon approval by the city council, the site development plan shall become a part of the zoning districts map. The plan may provide for staged development of the project and shall indicate so on the plan.
(6) 
Any substantial deviation from the plans submitted at the time of rezoning shall constitute a violation of the rezoning and any substantial change in plans shall be resubmitted for review following the same procedure required in the original adoption of the plan. The chief enforcement officer shall interpret what constitutes a “substantial” deviation or change in plan.
(7) 
The construction of the planned unit development shall be started within two years of the effective date of approval of the plan by the city council. Failure to begin the development within the two years shall automatically void the development plan and the land shall revert to the same zoning classification which existed immediately preceding the approval of the planned unit development.
(8) 
A homeowners’ association shall be created if other satisfactory arrangements have not been made for improving, operating, and maintaining common facilities, including streets, drives, service and parking areas, and recreation areas. When required, the owner shall establish a homeowners’ association in accordance with the requirements and procedures outlined by the FHA in sections 7 and 8.2 of the Land Planning Bulletin No. 6 entitled, “Planned Unit Development with a Homes Association,” as updated.
