Purpose And Scope. The division of the City into zoning districts is based on the principle that similar conditions prevail throughout a particular district. Development or redevelopment of certain uses within these districts has the potential, if not properly planned, to adversely impact the community with regard to traffic, incompatibility of uses, property values, utilities or in other ways. This Section is intended to authorize certain new or changed uses of property as well as certain site alterations, as specified herein, if the location and circumstances are appropriate for the use or change under the standards provided in this Section. To achieve these objectives, this Section provides increased flexibility of development design by authorizing the City Council to allow deviations to the underlying district regulations, subdivision regulations and other deviations where lawful, appropriate to the project, and while maintaining public safety and the purposes of the applicable codes, provided that a use that is not already authorized to be approved in an underlying zoning district may not be authorized by this PUD process. Approval by the City Council of a PUD Overlay District as provided herein shall be a legislative act of rezoning and, except as provided herein, subject to the procedural requirements for rezoning set forth in this Code and in Chapter 89, RSMo., as amended. Any ordinance approving a development plan shall be deemed to incorporate the provisions of this Article.
