(2) Where 40% or more of the frontage on one side of a street between two intersecting streets is developed with buildings that have not observed a front yard as described above, then:
(a) Where a building is to be erected on a parcel of land that is within 100 feet of existing buildings on both sides, the minimum front yard shall be a line drawn between the two closest front corners of the adjacent buildings on the two sides; or
