In any R District where the average depth of at least two existing front yards on lots within 200 feet of the lot in question and within the same block front is less than the least front yard depth prescribed elsewhere in this Zoning Code, the required depth of the front yard on such lot may be modified. In such cases, such depth shall not be less than the average depth of the 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 the front yard on any lot shall not be less than 20 feet.
