For the purpose of determining Building Height, the floor area of a dormer on a Dwelling shall not be included in the floor area calculation for a half story, provided that such dormer is not wider than eight (8) feet and the ridge line of the dormer does not exceed the ridge line of an existing Structure of which it is a part, or thirty-five (35) feet, whichever is less; and provided further that only the floor area of two such dormers shall not be included in the floor area calculation for a half story.

The minimum usable open space requirement is applicable only to Residential Uses and Dormitory/Fraternity Uses.
For any lot that exceeds the minimum lot area specified in this Table C, the required number of square feet of usable open space per dwelling unit shall be calculated by adding: (a) the minimum usable open space per dwelling unit specified in this Table C, and (b) twenty-five percent (25%) of the lot area in excess of the required minimum lot area specified in this Table C for the lot.
All ground level open space used to satisfy the minimum usable open space requirements specified in this Table C must have an unobstructed length of not less than ten (10) feet and an unobstructed width of not less than ten (10) feet, except that, for yards used to meet the open space requirements of this Table C, shorter or narrower dimensions are allowed where specifically permitted by the provisions of Section 65-45 (Application of Dimensional Requirements).
In 3F and the MFR Subdistricts, up to twenty-five percent (25%) of the usable open space requirement may be met by unenclosed porches (with or without roofs) or by suitably designed and accessible space on balconies of Main Buildings, on the roofs of wings of Main Buildings, or on the roofs of Accessory Buildings, provided that any such space on a porch, balcony, or roof has an unobstructed length of not less than six (6) feet and an unobstructed width of not less than six (6) feet.
