The purpose of the PUD, Planned Unit Development Overlay is to provide a degree of flexibility in regard to the use, area, height, bulk, and placement regulations for developments which qualify as planned developments. These may include, but are not limited to, residential, commercial, industrial, and mixed use developments. Certain large developments may be of such size and configuration as to justify a controlled degree of flexibility, and to permit a mix of land uses that may not normally be permitted in the zoning district, but would, under specific circumstances, increase convenience, be compatible with the overall character of the district, and not be injurious to adjoining properties. This designation shall not be allowed where it is sought primarily to avoid the imposition of standards and requirements of the underlying zoning classification(s) or other City requirements rather than to achieve the purposes stated above. PUDs are subject to design standards and regulations outlined in this Ordinance.
