(a) Hardship. Whenever the tract to be subdivided is of such unusual size or shape, or is surrounded by such development or unusual conditions that the strict application of the requirements of these Regulations would result in real difficulties, substantial hardship or injustice, the Planning Commission may vary or modify these Regulations so that the subdivider may subdivide his property in a reasonable manner. At the same time, however, the public welfare and interest of the City and the surrounding area must be thoroughly protected and the general intent and spirit of these Regulations must be enforced.
(b) Large Scale Development. The standards and requirements of these Regulations may be modified by the Planning Commission in the case of a plan or program for a new town, a complete community or a neighborhood unit, which, in the judgment of the Planning Commission, provides adequate public space and improvements for the circulation, recreation, light, air and service needs of the tract when fully developed and populated, and which also provides covenants or other legal provisions which will assure conformity to and achievement of the plan.
(c) Conditions. In granting variances and modifications, the Planning Commission may require such conditions as will, in its judgement, secure substantially the objective of the standards or requirements so varied or modified.
