Because each new subdivision and planned unit development (PUD) accepted by the City becomes a permanent unit in the basic physical structure of the future community, and to which the future community will, of necessity, be forced to adhere, all subdivisions and PUDs hereafter planned within the incorporated limits of the City, and within the unincorporated area lying contiguous with the corporate limits, shall, in all respects, be in full compliance with the regulations hereinafter contained in this chapter. These regulations are designed to provide for the orderly and harmonious development of the City, for the coordination of streets within new subdivisions with other existing or planned streets, and to secure a uniform system of utilities and services.
