Planned Unit District
A large-scale integrated development or a general plan special area of concern provides an opportunity for, and requires cohesive design when flexible regulations are applied; whereas the application of conventional regulation, designed primarily for individual lot development, to a large-scale development or special area may create a monotonous and inappropriate neighborhood. The planned unit district is intended to allow diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring substantial compliance with the general plan and the intent of the county code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale site or special area planning.
