Louisville is taking another step toward stricter parking enforcement.In 2010, on-street parking citations will be enforced by Republic Parking Systems. Republic takes over from Lanier Parking, which held the contract to issue parking tickets for five years.Parking Authority executive administrator Cathy Duncan says Republic's contract gives the company new power in collecting fees for unpaid parking tickets."They will employ the Fair Debt Credit Practice Act, which allows them to do skip tracing, repeated calling/mailing, reporting to the credit bureau," she says.Skip tracing is a technique for tracking delinquent parkers who have moved to other states.The contract change comes after the city instituted a new policy that allows officers to place immobilizing boots on cars with two or more unpaid tickets.Duncan says there are thousands of delinquent parking tickets in Louisville totaling some eight million dollars.
