A. Setbacks from the exterior boundary line of the PRD area shall be comparable to or compatible with those of the existing development of adjacent properties, or, if adjacent properties are undeveloped, the type of development which may reasonably be expected on such properties given the existing zoning of such properties or the projections of the Comprehensive Plan. In no event shall such setback be less than twenty feet.

B. Setbacks or side yards between buildings: The standard setbacks and yard requirements between buildings may be waived in a PRD. Buildings may have common walls and, therefore, built to the property line as in townhouse construction.

Wherever buildings are separated, a minimum distance of ten feet shall be maintained between such buildings. (Ord. 583 §2.16(F)(5), 1980).
