(b) The calculation for determining additional bulk shall include only that portion of the lot in the more restrictive use zone that is located within thirty-five feet (35 ft.) of the zone boundary line;

(c) The additional bulk authorized in this section shall not exceed the maximum bulk permitted on the portion of the lot located in the lesser restrictive use zone;

(d) For computation purposes, any portion of the lot located in an R-1 or R-2 zone shall be deemed to be limited to a floor area ratio (FAR) of 0.4, any portion of the lot located in an R-3 zone shall be deemed to be limited to an FAR of 0.6, and any portion of the lot located in an RF-1, RF-2, or RF-3 zone shall be deemed to be limited to an FAR of 0.9; and

(b) In authorizing an extension, the Board of Zoning Adjustment shall require compliance with Subtitle A § 207.1(d);

(c) The extension shall have no adverse effect upon the present character and future development of the neighborhood; and
