The longstanding and at times violent protests against Atlanta's planned police and firefighter training center are partially responsible for a nearly $20 million rise in costs connected to the project, city officials said. The 85-acre (34-hectare) project, which critics call “Cop City,” is now expected to cost $109.65 million, up from a previous estimate of $90 million, Atlanta Deputy Chief Operating Officer LaChandra Burkes told City Council members on Wednesday. Atlanta has already committed $67 million toward the project, but Burkes emphasized that taxpayers would not be on the hook for the newly incurred security, insurance, legal and construction costs.
