Whenever a subdivision is developed as a modern neighborhood unit where adequate park area is provided, through traffic is adequately cared for, and the majority of the minor streets are of cul-de-sacs, the Planning Commission may vary the requirements of Sections 1177.03 through 1177.06 to allow the subdivider more freedom in the arrangement of the streets and lots, but at the same time protect the convenience, health and safety of the future residents of the subdivision as well as the general welfare of the City.  In no case, however, shall the lot area per family requirement be less than is required in any zoning regulations.
(1980 Code 152.24)
