If the height per story of a building, when all the stories are added together, exceeds an average of 15 feet, then additional gross floor area shall be counted in determining the floor area ratio of the building, equal to the gross floor area of one additional story for each 15 feet or fraction thereof by which the total building height exceeds the number of stories times 15 feet; except that such additional gross floor area shall not be counted in the case of live/work units or a church, theater or other place of public assembly.

(b) Where the lot is level with or slopes downward from a street at the centerline of the building or building step, such point shall be taken at curb level on such a street. This point shall be used for height measurement only for a lot depth not extending beyond a line 100 feet from and parallel to such street, or beyond a line equidistant between such street and the street on the opposite side of the block, whichever depth is greater. Measurement of height for any portion of the lot extending beyond such line shall be considered in relation to the opposite (lower) end of the lot, and that portion shall be considered an upward sloping lot in accordance with Subsection (c) below, whether or not the lot also has frontage on a lower street.
(c) Where the lot slopes upward from a street at the centerline of the building or building step, such point shall be taken at curb level for purposes of measuring the height of the closest part of the building within 10 feet of the property line of such street; at every other cross-section of the building, at right angles to the centerline of the building or building step, such point shall be taken as the average of the ground elevations at either side of the building or building step at that cross-section. The ground elevations used shall be either existing elevations or the elevations resulting from new grading operations encompassing an entire block. Elevations beneath the building shall be taken by projecting a straight line between ground elevations at the exterior walls at either side of the entire building in the same plane.
(d) Where the lot has frontage on two or more streets, the owner may choose the street or streets from which the measurement of height is to be taken, within the scope of the rules stated above.
Where the height limits for buildings and structures are established by this Code, the upper points to be taken for measurement of height shall be as prescribed in the provisions relating to such height limits.

A lot as so defined generally consists of a single Assessor's lot, but in some cases consists of a combination of contiguous Assessor's lots or portions thereof where such combination is necessary to meet the requirements of this Code. In order to clarify the status of specific property as a lot under this Code, the Zoning Administrator may, consistent with the provisions of this Code, require such changes in the Assessor's records, placing of restrictions on the land records, and other actions as may be necessary to assure compliance with this Code. The definition of "lot" shall also be applicable to piers under the jurisdiction of the Port Commission.
