The purpose of these regulations is to encourage the appropriate development of tracts of land sufficiently large to allow comprehensive Planning and Zoning, and to provide flexibility in the application of certain provisions of this Zoning Code. It is the further purpose of this chapter:
(a) To produce a comprehensive development equal to or better than that resulting from traditional lot by lot land use development.
(b) To recognize the problems of population density, distribution and circulation, and to allow a deviation from rigid established patterns of land use, but controlled by defined policies and objectives.
(c) To permit flexibility of design in the placement and use of buildings and open spaces, circulation facilities and off-street parking areas, and to more efficiently utilize potentials of site characterized by special features of geography, topography, size or shape.
(d) To obtain creative and coordinated designs harmonious and compatible with surrounding uses.
