Cobb Commissioners, Police Department leadership, and property management officials cut the ribbon for the new police headquarters on Fairground Street in Marietta last month. The building, a former credit union, underwent $16 million in renovations paid for through the 2016 Special Purpose Local Option Sales Tax. It enabled the department to consolidate sections such as records, permitting, crimes against person unit, internal affairs unit, technology-based crimes, VIPER, and command staff.
