In any R District, where the average depth of at least two existing front yards on lots within 100 feet of the lot in question and within the same block front is less or greater than the least front yard prescribed elsewhere in this Zoning Ordinance, the required depth of the front yard on such lot shall be modified. In such cases, this shall not be less than the average depth of such existing front yards on the two lots immediately adjoining, or, in the case of a corner lot, the depth of the front yard on the lot immediately adjoining; provided, however, that the depth of a front yard on any lot shall be at least ten feet and need not exceed fifty feet; and provided further, that in no event shall the depth of a front yard of a corner lot be less than twenty-five feet.
(a) Steep Slopes; Front Yard Garage. In any R District where the natural grade of a lot within the required front yard has an average slope, normal to the front lot line at every point along such line, of such a degree of percent of slope that it is not practicable to provide a driveway with a grade of twelve percent (12%) or less to a private garage conforming to the requirements of this Zoning Ordinance, such garage may be located within such front yard, but not in any case closer than twelve feet to the street line.
(b) Double Frontage Lots. Buildings on lots having frontage on two nonintersecting streets need not have a rear yard if an equivalent open space is provided on the lot in lieu of such required rear yard; applicable front yards must be provided, however, on both streets.
