We wish we had enough snowplows and drivers to take care of every street right away, but our resources are limited and so we must adhere to a carefully laid out system for clearing the streets. If we allowed our plows to be diverted each time a special request was made, our system would be destroyed and it would take far longer to get all the streets in the municipality cleared. To keep our snow removal operations as effective and efficient as possible, plows are not permitted to deviate from their assigned routes. Highways and arterial streets have first priority for snow plowing, and then collectors and then the remainder of the streets are then plowed.
