A. 
The purpose of the planned unit development district is to provide the means and the guidelines through which tracts of land are developed through an overall master land use plan that integrates the land uses and site considerations for the land as a unit, rather than the traditional standard treatment of land uses in other zone districts. It is intended to reflect maximum design freedom to make the best use of topography and land features and to permit the developer an opportunity to more fully utilize the physical characteristics of the site, and to encourage mixed-use developments, including uses such as residential, office, commercial, and industrial; and to encourage higher quality development than possible under traditional standard zoning regulations. Through the planned unit development zoning process, it is the intent that property will be developed with a unified design providing continuity between the various elements. It is further intended to achieve economics in land development, maintenance, street systems, and utility and drainage networks while providing usable, open spaces, and planned vehicle and pedestrian circulation for the inhabitants.
B. 
Except as otherwise restricted, the planned unit development may be proposed as a substitute for any existing zone and may be initiated by the owner as defined in this title and under the procedures of this chapter. The planned unit development may be used for residential, office, commercial, industrial, or agricultural purposes or any combination thereof.
(Ord. 17-026 § 1, 2017)

A. 
A zoning designation map with a master conceptual site plan;

Be compatible with the goals and policies of the city master plan and other applicable adopted plans and policies;
C. 
Be compatible with the area surrounding the project site and place no greater demand on existing city facilities and services than can be furnished by the city;

Promote the efficient use of land by means of more economical arrangement of buildings, circulation systems, land uses, densities, and utilities;
E. 
Provide for usable and suitably located open space such as, but not limited to, bicycle paths, playground areas, courtyards, tennis courts, swimming pools, planned gardens, outdoor seating areas, outdoor picnic areas, and similar open space;
F. 
Demonstrate flexibility and quality in design to permit diversification in the location, type, and uses of structures;
G. 
Combine and coordinate architectural styles, building forms, and building relationships within the development and in concert with adjacent and surrounding land and development;
H. 
Minimize impact on adjacent zoning districts by limiting building heights, providing screening and/or other buffers;

Preserve and utilize where possible, existing landscape features and amenities and encourage the harmonious combination of such features with structures and other improvements;

K. 
Consist of such a mixture of uses, density, or characteristic or creative design;
L. 
Constitute a buffer zone between existing land uses and existing zones;

(Ord. 17-026 § 1, 2017)
A. 
Minimum lot area, width, and yard requirements of other districts do not apply in the PUD.
B. 
All subdivision design and construction requirements shall meet the requirements of Title 16 of the Riverton Municipal Code. Alternative design and construction requirements may be authorized by the city council during the PUD site plan approval or amendment process. Alternative design and construction requirements must be submitted to the community development department prior to council review and must meet general acceptable good engineering practices.
(Ord. 17-026 § 1, 2017)
A minimum of the following total land areas shall be retained as usable open space:
A. 
Residential uses, 20% of the total land area;
B. 
Commercial, 10% of the total land area;
C. 
Industrial, 10% of the total land area.
(Ord. 17-026 § 1, 2017)
The type of proposed construction shall be described in the PUD application, providing that:
A. 
If the spacing between main buildings is not equivalent to the spacing which would be required between buildings similarly developed under this title on separate parcels, other design features shall provide light, ventilation, and other characteristics equivalent to that which would have been obtained from the spacing standards.
B. 
Buildings, off-street parking and loading facilities, open space, landscaping, and screening shall provide protection outside the boundary lines of the development comparable to that otherwise required of similar development in other existing districts.
C. 
The maximum building height shall not exceed four stories or 50 feet for residential uses, or eight stories or 75 feet for commercial, office, and industrial uses, except that a greater height may be approved if surrounding open space within the PUD, building setbacks, and other design features are used to avoid any adverse impact due to the greater height. Architectural feature(s) may exceed height limit with city approval through the board of adjustment.
(Ord. 17-026 § 1, 2017)
If the PUD is used as a separate zoning district, the number of units will be determined as provided in the PUD, with the PUD differing uses to be based upon the Riverton city code that most closely reflects the property use.
