For Conservation Cluster Developments consisting of at least a majority of single-family detached dwellings, at least 35% of the land area of the tract, exclusive of land set aside for road and drainage areas, shall be designated as Open Land. For Conservation Cluster Developments consisting of at least a majority of single-family attached dwellings, at least 50% of the land area of the tract, exclusive of land set aside for road and drainage areas, shall be designated as Open Land. For the purpose of this article, "Open Land" is defined as a parcel or parcels of land, or an area of water, or a combination of land and water, not including roads or ways, whether public or private, The Open Land shall be reserved for open space, conservation, agriculture, passive recreation, park purposes or some combination of the foregoing.

1803.1.7.2. In order to limit the degree to which the Open Land may have an irregular shape, and to optimize the public and ecological value of the Open Land, the following Lot Shape Factor formula shall be used: Lot perimeter squared ÷ Actual Lot area = Lot Shape Factor. Eighty-five percent (85%) of the area of the minimum required Open Land shall not have a Lot Shape Factor greater than 50. See examples below:
