Streamwood officials have agreed to pay a contractor an extra $61,650 to remove 200 more trees destroyed by the emerald ash borer.
The majority will be uprooted over the next three months, public works officials say.
Since 2011, crews have cleared more than 2,000 trees and replanted 912. A more diverse mix of trees are planted each fall to ward off pest problems.
