Cul-de-sacs are especially difficult for snow removal operations. In a light snow, a circle may not receive treatment unless there is an incline. During plowing operations where all streets are plowed, drivers must push snow into available open spaces (i.e. around fire hydrants, between mailboxes, driveways and storm sewer inlets). Many times, cul-de-sacs have parked cars, which further complicate plowing.
