For publicly-owned land zoned PRO, there are no minimum lot area or dimension requirements. For non-publicly owned open space, the minimum width of such areas shall be 100 feet unless the area provides for a trail system or preservation of a natural drainage way. Widths less than 100 feet are generally not permitted and are considered a break in continuity of the open space area. The minimum lot area for non-publicly owned open space is 87,120 square feet (2 acres).
