Under the proposal, the University's highest-paid employees would see a large permit cost increase, while lower-paid employees and students would have a significantly smaller increase.
Committee members have until the end of the semester to officially recommend an option to the University vice chancellors.
Permit prices could be raised as part of a five-year plan to help officials eliminate a budget deficit caused by the cost of gating parking lots, the loss of spaces to construction and a court ruling that requires UNC to hand over money from parking fines to area school districts.
Last year, the Transportation and Parking Advisory Committee, which has since been replaced by ACT, attempted to solve the budget crisis with a night parking plan.
The plan was rejected by the UNC Board of Trustees, forcing ACT to devise a new funding source.
The sliding-scale option, proposed by the faculty last year, seems to be the "most equitable way to distribute the cost of parking on campus," said Sue Estroff, Faculty Council chairwoman and a member of ACT.
Employees who earn less than $50,000 per year and students would see an annual price increase of up to 5 percent.
Employees earning salaries between $50,000 and $100,000 would pay an annual increase of up to 10 percent.
Those employees who earn more than $100,000 would face price increases up to 20 percent each year.
