      (1)   In a developed block where more than fifty percent of the existing buildings have setbacks which exceed the fifty-foot minimum, the setback to be required of new construction on such block shall be equal to the average setback distance of all developed lots on the block, not to exceed 100 feet, unless the owner of the lot on which the new construction is taking place desires a front yard in excess of 100 feet.

      (2)   In a developed block where more than fifty percent of the existing buildings have setbacks of less than fifty feet, the setback to be required of new construction on such block shall be equal to the average setback distance of all developed lots on the block.

   For purposes of this section, "average setback distance" shall be determined by totalling the actual setback distances of all developed lots on the block in question and dividing the sum total by the number of individual developed lots.
