Whenever the tract to be subdivided is of such unusual size or shape or is surrounded by such development of unusual conditions that the strict enforcement of the regulations would entail practical difficulties or unnecessary hardships, the city council by resolution, after public hearing and after report by commission, may vary or modify them in such a way that the subdivider is allowed to develop his property in a reasonable manner, but at the same time, the public welfare and interests of the city and county are protected and the general intent and spirit of the regulations preserved.
