All projects containing land identified as open space on the Croman Mill District Zoning map shall dedicate those areas as park or common open space. It is recognized that the master planning of the properties as part of the Croman Mill Site Redevelopment Plan imparted significant value to the land, and the required dedication of those lands within the Croman Mill District for open space and conservation purposes is proportional to the value bestowed upon the property through the change in zoning designation.
