[Ord. No. 99-99 §1, 7-12-1999]
The general purpose of this Article of the Unified Development Ordinance is to permit greater flexibility and more creative and imaginative design for the development of mixed land uses that is generally possible under conventional zoning regulations. This district is intended to promote a more economical and efficient use of land, to provide a harmonious variety of housing choices, to provide greater flexibility in the placement of buildings, to preserve the natural scenic qualities of open space, and to utilize the best potentials for site development relating to such features as topography, geography, and the size and shape of properties.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 07-040 §1, 3-13-2007]
A. 
Improve Development Design.
1. 
By providing a planned mixture of land uses while maintaining adequate open space, common facilities, and buffers between uses.
2. 
By permitting land use designs that incorporate natural terrain features, to preserve natural open spaces and encourage the philosophy of design with nature.
B. 
Address And Accommodate Housing Needs.
1. 
By providing a mixture of housing types while maintaining density standards to protect residents from overdevelopment.
2. 
By allowing zero (0) lot line development to reduce housing costs.
C. 
Establish, Maintain And Strengthen The Neighborhood Concept In The Community Setting.
1. 
By allowing non-residential uses within the planned unit development, thereby discouraging strip commercial development.
2. 
By encouraging pedestrian and non-motorized vehicle paths and ways utilizing natural terrain features rather than traditional design.

To enhance the attractiveness of developing under PUD regulations, the applicant may be eligible for a maximum increase of twenty-five percent (25%) in the total number of dwelling units to be developed under a rezoning to a "PUD" Overlay District. Percentage increases in the number of dwelling units are to be applied individually and treated as additive, and not compounded. Such percentage increases in density may be recommended by the Planning and Zoning Commission and approved by the Governing Body, according to the following:
Maximum Percentage Increase
Design Element
2%

Notwithstanding any other provision of the UDO to the contrary, property zoned or used commercially shall not be used to calculate allowable density in residential areas of the PUD.
