The frontage of a lot shall mean the portion of the front property line which directly abuts a street right-of-way, alley or private way. If a parcel contains frontage along more than one such street right-of-way, alley or private way, only one such frontage shall be counted when determining whether the lot has the minimum frontage required for the zone in which it is located. In general, the street from which a lot is accessed shall be considered the frontage. (Ord. 89-1 § 1, 1989.)
