(a) Average Depth of Front Yards. 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 depth prescribed elsewhere in this chapter, the required depth of the front yard on such lot shall be modified. In such case, this shall not be less than the average depth of the existing front yards on the two lots 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.
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 or 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 chapter, such garage may be located within such front yard, but not in any case closer than six feet to the street line.
Buildings on lots having frontage on two nonintersecting streets need not have a rear yard if an equivalent open space is provided however on both streets.
(b) Computing Rear and Side Yards. In computing the depth of a rear yard or the width of a side yard, where the rear or side yard abuts an alley, one-half of the width of the alley may be included as a portion of the required rear or side yard, as the case may be, provided however, that no side yard shall be less at any point than three feet and no rear yard less than ten feet.
(c) Side Yard Modifications. Each side yard, where required, shall be increased in width by two inches for each foot by which the length of the side wall of the building adjacent to the side yard exceeds forty feet.
Side yard width may be varied where the side wall of a building is not parallel with the side lot line or is broken or otherwise irregular. In such case, the average width of the side yard shall not be less than the otherwise required least width, provided however, that such side yard is not narrower at any point than one-half the otherwise required least width, or narrower than three feet in any case.
A side yard along the side street lot line of a corner lot, which lot abuts in the rear either directly or across an alley, the side lot line of another lot in an R District, shall have a width of not less than one-half the required depth of the front yard on such other lot fronting the side street.
