The maximum height, including the foundation, of any primary structure shall not be greater than 35 feet or 125% of the average height of the principal structures on the two lots abutting each side of the lot, whichever is less. When one of the abutting lots is vacant, the next developed lot on the same block face shall be used. Where there is only one abutting lot on the same block face, it shall be used for this calculation. When the subject lot is on a corner, the maximum height shall be calculated for each street and limited to 35 feet or 125% of the average height of the lesser value. When 125% of the average of the abutting structures is less than 27 feet, a maximum height of 1.5 stories in 27 feet shall be permitted.
2. The maximum height, including the foundation, of any accessory structure shall not be greater than 27 feet.
3. For the purposes of this section, height shall be measured from grade or, if present, the top of a foundation which shall not exceed three feet above grade, to the roof line.
C. Maximum building coverage. The maximum building coverage (excluding detached garages and other accessory buildings) shall be a maximum of 150% of the average of the building coverage (excluding detached garages and other accessory buildings) of the two abutting lots on each side. When the abutting lot is vacant, the next developed lot shall be used. Where there is only one abutting lot on the same block face, it shall be used for this calculation. When the subject lot is on a corner, the maximum building coverage shall be calculated and met for each street.
D. Access and driveways, garages and parking areas.
1. Access and Driveways.
