Planned Unit Developments District
This Section establishes the regulations and standards for Planned Unit Developments (PUD) as a zoning district and as Conditional Uses (PUD Overlay). A Planned Unit Development allows for variations from the strict application of the standards of the County’s conventional zoning districts in order to allow flexibility for landowners and developers to creatively plan for the overall development of their land.
