Residents who ignored that stack of dog-eared tickets found out the day they applied for a driver’s license that you either have to pay up or start walking. And now Ward 2 Councilmember Jack Evans wants to apply this tried-and-true enforcement strategy to a different set of scofflaws: illegal trash dumpers who fail to pay the appropriate fines. Under legislation proposed by Evans, the city would withhold permits or licenses from any resident or business with outstanding fines, taxes, or liens issued by any city agency. The primary aim of the “clean hands” requirement is to assist the Department of Public Works (DPW) in enforcing the city’s sanitation code. Last year, DPW assessed nearly $1.2 million in litter fines, but collected a meager $100,000.
