AUBURN â DeKalb County Commissioners are looking at ways to spend $8.4 million the county is expecting from the new federal American Rescue Plan. They reacted positively Monday to a suggestion for using some of it to buy a new radio tower for the Central Communications emergency dispatching service. A 180-foot tower at the Central Communications site near DeKalb High School would cost between $300,000 and $500,000, said Central Communications Director Brian Humbarger, who made the suggestion. âIt just makes sense to put all of our resources and some of the cityâs resources on a tower,â Humbarger said. He referred to the City of Auburn, which he said is planning to take down its aging, 160-foot tower at City Hall.
