The 169-acre parcel located in the northern part of Chapel Hill originally was purchased for the purpose of expanding the adjacent Orange County Landfill, said Carrboro Town Manager Robert Morgan.
But the approved resolution relegates 18 acres to affordable housing and sets the rest aside as open space.
Because the Greene tract is under the joint jurisdiction of Carrboro, Chapel Hill and Orange County, each governing body must approve the resolution for it to be adopted.
The Chapel Hill Town Council approved the resolution 8-1 on Nov. 11.
Discussion about the Greene tract resolution is not on the agenda for either of the two remaining Orange County Commissioners' meetings scheduled for 2002.
The low percentage of land to be used for affordable housing in Carrboro was the major source of contention at Tuesday's meeting.
The board originally requested that 25 acres be set aside for affordable housing, said Alderman Joal Broun, who voted against the resolution.
"I just cannot, in good conscience, approve this plan," she said. "I don't think 18 is enough. I didn't think 25 was enough."
Broun said she disapproved of the 18 acres' location, which Morgan said was determined by the availability of a gravity-controlled sewer system for the area.
