PD
Planned Development District
The PD District is intended to be used when unified, large scale, mixed use developments are proposed in areas lacking a predominant urban/suburban development pattern and adjacent land use compatibility is not a significant factor. Broad, general concept plans would be permitted with limited flexibility to accommodate land use changes in response to evolving market conditions.
