The Charlotte Area Transit System is receiving less money from the half-cent sales tax than it expected this year. Officials are looking at possible service cuts to make due with the revenue that's millions of dollars lower than projected. The sales tax pays for nearly two-thirds of CATS operating costs. So far revenue has been flat between this year and last. Jennifer Green, a CATS spokeswoman, says the department is considering changes in its routes that have the fewest riders. "That could be the number of times we run a service a particular time a day. Or that might be an actual change to a route. We may reduce the length of a route or the times that it runs," says Green. CATS plans on getting feedback from neighborhoods before recommending any cuts to the planning commission. Green says the board will make its decision before December. The changes are likely to go into effect in February.
