It shall be the policy of the city to promote progressive development of land and construction thereon by encouraging planned unit developments to achieve:
(A) A maximum choice of living environments by allowing a variety of housing and building types and permitting an increased density per acre and a reduction in lot dimensions, yards, building setbacks, and area requirements;
(B) A more useful pattern of open space and recreation areas and, if permitted as part of the project, more convenience in the location of accessory commercial uses and services;
(C) A development pattern which preserves and utilizes natural topography and geologic features, scenic vistas, trees and other vegetation, and prevents the disruption of natural drainage patterns;
(D) A more efficient use of land than is generally achieved through conventional development resulting in substantial savings through shorter utilities and streets;
(E) A development pattern in harmony with land use density, transportation facilities, and community facilities objectives of the comprehensive plan.
