(a) Intent. In order to encourage greater attractiveness, flexibility, and fuller utilization of yard spaces, when a group of 3 or more contiguous one- or two-family dwellings is designed and developed as a unit, the following planned variations to the yard regulations may be permitted.
(b) Front Yard. The depth of front yards may be varied by increasing or decreasing the setback, provided the setback is decreased not more than 10 feet from the established building line, and the average depth of the front yards for the entire unit development is not less than the minimum depth required for front yards in the district in which they are located.
(c) Side Yards. The width of side yards may be varied by locating the "service" side of 2 dwellings (kitchens, garages, utility rooms) opposite each other on adjacent lots, providing the "living" sides (living, sleeping rooms) are located opposite each other on other adjacent lots. Then the total yard width for the 2 "service" side yards shall be not less than the total of 2 minimum side yards, and the width for the other 2 "living" side yards shall be not less than the total of the larger side yards; provided, however, the total width of the 2 side yards on each lot is not less than that required for the district.
(d) Approval. Development plans showing the location of buildings, yards, driveways, and other site improvements for the entire "unit development" shall be submitted to the Commission, and until approved by it, building permits shall not be issued.
