But University officials say the $2,600 price tag is reasonable.
The new site development permit application fee will affect only those areas in Chapel Hill classified as Office/Institutional-4, a zone created by the Town Council on July 2 in response to University demands for more space.
Presently the University is the only entity occupying the OI-4 zone.
This measure came days after the town's Oct. 3 approval of the Development Plan, the University's eight-year plan for growth.
The Development Plan is an early phase of the University's Master Plan, a 50-year blueprint for campus growth, which proposes to add 5.8 million square feet to UNC's current 13.8 million.
Council member Bill Strom said this expansion beyond the 14 million square foot boundary of the OI-3 zone warranted creation of the new OI-4 zone.
Strom said the action is not an attempt by the town to punish the University after the approval of its Development Plan, which many town residents opposed.
"The town has established a principle of recovering the full cost of services for all planning actions taken," he said.
Strom said this principle was established during the 2000-01 council term before the Development Plan existed.
