The Gazette reports that Billings’ record to-date snowfall once again activated residential snowplowing Thursday morning, and the growing public cost to pay private operators may soon drift into the red. Of the $420,000 allocated for residential snowplowing during the current fiscal year, about $75,000 remains. The current storm should take care of that, and it will take up to $20,000 in additional cost to finish clearing residential streets from the current storm.
