2The pole, which connects the flag to the street; provides the only street frontage and access for the lot; and at any point is less than the minimum lot width for the zone.

B. A lot when, as a result of an approved and recorded street closing or withdrawal, the only street frontage and access to the lot is less than the minimum lot width, in which case the “pole” shall be considered the width of frontage along the street.

Lot Area: The total area within the lot lines of a platted lot.

Lot of Record: Also called “lot” or “parcel”, a parcel of land described by metes and bounds, or otherwise delineated by property boundary dimensions, on a plat recorded in the office of the appropriate Register of Deeds.

Lowest Adjacent Grade (LAG): means the elevation of the ground, sidewalk or patio slab immediately next to the building, or deck support, after completion of the building.
