[Added 6-18-2018 by Ord. No. 18-01]
The purpose of this district is to permit flexibility in the regulation of land development; to encourage innovation in land use and variety in design, layout and type of structures constructed; to achieve economy and efficiency in the use of land, natural resources, energy and the provision of public services and utilities; to encourage provision of usable open space and protection of natural features; to provide adequate housing, employment and shopping opportunities particularly suited to the needs of the residents of the city; and to encourage the use, reuse and improvement of existing sites and buildings which will be developed in a compatible way with surrounding uses but where the uniform regulations contained in other zoning districts do not provide adequate protections and safeguards for the site or surrounding area. The district is intended to accommodate developments with one or more land uses, sites with unusual topography or unique settings within the community or sites that exhibit difficult or costly development problems or any combination of these factors. This zoning district shall not be allowed where this zoning classification is sought primarily to avoid the imposition of standards and requirements of other zoning classifications or other city regulations rather than to achieve the stated purposes above.
All permitted principal uses by right or by special use permit in any district as identified in Article II shall be permitted in the PUD district.
Based upon the following standards, the Planning Commission may recommend denial, approval, or approval with conditions, and the City Council may deny, approve, or approve with conditions the proposed planned unit development.
(a) 
Off-street parking shall be sufficient to meet the minimum required by the ordinances of the City. However, if it is deemed necessary in order to achieve the purposes of this section, the Planning Commission may relax parking requirements during site plan review.
(b) 
All streets within the planned unit development shall meet the minimum requirements of the City Subdivision Control Ordinance and/or all municipal standards, unless modified by the Planning Commission.

Any other change will require approval following the procedures outlined above for the original approval. Appeal of the Building Official/Zoning Administrator's decision regarding the need for formal review by the Planning Commission and City Council may be appealed to the City Council.
