Chapel Hill Police Chief Gregg Jarvies submitted a proposal to the Chapel Hill Town Council on Monday requesting approval to divert all motor vehicle traffic within a one-mile radius of the downtown business area Oct. 31.
The proposal also would prohibit all public parking within the restricted area. Residents who live within the zone would be granted admittance by the police department only upon request.
"This event has grown to such an enormous size that we no longer have the resources to manage it safely," he said.
He also said the proposal does not intend to curb local participation but aims to discourage attendance of people from outside the Chapel Hill area.
"Part of being in this community is enjoying events such as this," Jarvies said. "Our hope is not to stop the celebration. It is to minimize it."
Last year's Halloween festivities drew more than 50,000 people to the area, and more than 200 police officers were on duty to regulate the event.
Jarvies said the Chapel Hill Police Department had to request additional police assistance from over 20 jurisdictions located throughout the state.
More than 150 officials from the town's transportation, public works and fire departments also were utilized last year.
Jarvies said the enormous number of people who attend the celebration often park illegally and leave behind an extensive amount of litter in local areas.
