It is recognized that an integrated development provides an opportunity for creative design when flexible regulations are applied. The planned unit development zone is intended to allow for innovative design and diversification in the relationship of various uses, buildings, structures, lot sizes and open space while ensuring substantial compliance with the general plan and the intent of the municipal code. In addition, the development would provide adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. This zone is not to be used to restrict residential development or to compromise other zoning districts that may be more appropriate for a site. Instead, it enables a developer to obtain approval of a specific, detailed plan for a residential neighborhood which ensures that the uniqueness of the project design is preserved. These standards shall be observed without unduly inhibiting the advantages of modern site planning techniques and innovative planning of residential neighborhoods. Land may be classified as being solely within a PUD zone (exclusive zone), or the PUD zone may be used as a combining zone in a R-1, R-2, R-3 or R-4 zone to assign a base zone defining allowable uses and ensure future site development will be compatible with surrounding development and/or to recognize unique site characteristics.
