(a) EXISTING LOTS OF RECORD.
(1) Nothing contained herein shall prohibit the use of an existing lot of record, as defined in Section 1327.02, which does not comply with the District Schedule of Area and Bulk Regulations, provided that each of the following criteria are satisfied:
A. Development of the lot shall satisfy all applicable requirements of the City of Wheeling, the Ohio County Health Department and the West Virginia State Departments of Health and Environmental Conservation for potable water supply and sewage disposal facilities.
B. If developed for residential use, use of the lot shall be limited to one principal single-family dwelling.
(2) All other area and bulk regulations for the district shall be met.
(b) CORNER LOTS AND YARDS.
(1) Each street frontage on a corner lot shall be deemed to be a front street line, and the required yard along each such lot line shall be a required front yard.
(2) Such lots shall be deemed to have two front yards and two side yards, and no rear yards.
(3) Any corner lot delineated by subdivision after the adoption of this Zoning Ordinance shall provide a side street setback line that shall not be less than the minimum front yard required on any adjoining lot fronting on the side street.
(c) LOT FRONTAGE. The minimum lot frontage of any lot shall be measured along the minimum building setback line as required for the district in which it is located.
(d) THROUGH LOTS. Where a single lot under individual ownership extends from a street to a street, the widest frontage shall be deemed the street upon which the property fronts.
(e) MINIMUM LOT SIZE FOR PUBLIC AND SEMI-PUBLIC BUILDINGS. All public or semi-public buildings, such as clubs, schools, or places of worship, shall be located on a lot with not less than 20,000 square feet. All other regulations for the zone in which the use is located shall be complied with.
(f) VACANT LOTS: CONTEXTUAL FRONT YARD. When a vacant lot is situated between two improved lots, each having a principal building within twenty-five feet of any side lot line of such unimproved lot, the front yard of the vacant lot may be reduced to the greatest depth of the front yard of the two adjoining improved lots, but shall be not less than ten feet. However, where any lot fronts on a right of way which on the Official Map of the City is proposed to be widened, the front yard of the lot shall be required in the district where the lot is located and shall be measured from such proposed future right of way.
