Applicants may propose to modify lot size, unit placement, shape, and other dimensional requirements otherwise applicable to the OSRD, subject to the following:
Frontage –No lot within an OSRD shall have less than fifty (50) feet of frontage. This frontage requirement shall apply only to lots fronting on proposed internal roadways. However, the Planning Board may waive this minimum frontage requirement where it is determined that such reduced lot (s) will further the goals of this bylaw.
Setbacks – Every dwelling unit fronting on the proposed roadways shall be set back a minimum of twenty (20) feet from the front property line, and ten (10) feet from any rear or side lot line. In no event shall individual dwelling units be closer than thirty (30) feet to each other.
Lot Size – The minimum lot size shall be no less than 1/3 the square footage otherwise required in the Zoning District in which the subdivision is located or 10,000 square feet whichever is greater.

For each additional ten percent (10%) of the site (over and above the required 50%) set aside as open space, a bonus of five percent (5%) of the Basic Maximum Number may be awarded.
