Dunkin Donuts has lost a court fight with the City of Danbury's Planning Commission. The coffee chain applied for a special permit to open a drive-thru at 110 Mill Plain Road, but the Commission denied the request. Dunkin estimated that the drive-thru would be 60-percent of their business, but the zone doesn't allow for those kinds of windows. Planners said the traffic design was configured in an unconventional way. The company called the Commission's decision retaliatory, discriminatory, and reached without evidence that a drive-thru would make traffic worse. Judge Andrew Roraback ruled that the traffic flow would be problematic and that zoning authorities must be able to make decisions because on reasonable planning for contemporary or future conditions.
