On any lot running through from one (1) street to another, the front of the lot shall, for the purposes of this section, be considered that frontage upon which the majority of the buildings in the same block front; but in case there has been no clearly defined building frontage established, the owner may, when applying for a building permit, specify which lot line shall be considered the front lot line for the purposes of this section.

In the case of lots fronting on the turnaround of a cul-de-sac street or fronting upon any other curved street, lot frontage (as distinguished from lot width) may equal but shall be no less than two-thirds (2/3) of the required lot width as set forth in Schedule I[1] and further provided that no lot shall have a frontage of less than sixty (60) feet, except in the R-6 zone where a minimum of forty (40) feet shall be required.

Lot frontage by means of a private access easement or private street may be permitted in accordance with standards and procedures set forth in Article V.
