It takes 144 employees. We are currently understaffed by 30 CDL drivers. Although we are actively recruiting CLD drivers, there is an ongoing nationwide shortage of CDL drivers.
Mailboxes, newspaper delivery boxes, or fences installed alongside the traveled roadway are at the owner’s risk. If an operator strikes a mailbox or fence with a plow, the operator will report it and we will repair it as soon as possible. Mailboxes and fences damaged by snow load during normal plowing operations are not the responsibility of the County. If a mailbox is struck by a plow, it will be replaced with a standard rural mailbox.
We do not remove packed snow and ice from residential roads passable by passenger cars.
Road & Bridge is not responsible for private property. Please contact your property manager.

Each snow event is unique, we cannot give an estimated arrival time.

Jefferson County does not have an ordinance requiring citizens to shovel sidewalks, but the county encourages citizens to shovel walks adjacent to their homes as a courtesy to their neighbors and for the safety of pedestrians.
Residents of incorporated areas are urged to check with their city governments for any policies regarding snow removal from sidewalks. Residents in unincorporated areas of Jefferson County who live within the boundaries of a homeowners association are urged to check with their HOA for any regulations regarding sidewalk maintenance.
Roads are plowed based on their priority, meaning arterials and main routes are cleared first. Your road may be a secondary route plowed after the school bus and emergency routes are open. Drivers are placed on a 12-hour shift based on currently available manpower. A schedule cannot be enforced because each storm presents unique situations.
Driveway approaches affected during Phases I, II, and III are the responsibility of the property owner or resident to clear. See Snowplowing & Ice Control Procedure approved by the Board of County Commissioners.
We must obey traffic laws and cannot provide custom plowing. Plowing a windrow of snow into oncoming traffic is a safety hazard.
