Snow Plow Priorities
  1. 1st Priority: Emergency Roads
  2. 2nd Priority: Main Roads
  3. 3rd Priority: Secondary Roads and Cul-De-Sacs
When a Snow Emergency Plan is in Effect
  • Vehicles traveling on the roads must be equipped with snow or all-weather radial tires or chains.
  • No parking is permitted along designated Snow Emergency Routes.
County Maintained Roads Exclude
  • State roads (numbers routes e.g. I-95, MD Route 543/Fountain Green Road)
  • Roads within the incorporated municipalities (Town of Bel Air, City of Havre de Grace, and City of Aberdeen)
  • Private roads
Pushing Procedure
Driver’s are required to widen or push back curb to curb to open inlets and drainage courses to prevent melting snow from becoming packed ice or causing flooding problems. Also pushing curb to curb allows mail carriers to deliver mail and placement of snow behind curb for future snow events. Parking your vehicles in the street greatly hinders snow removal operations and risks property damage as large equipment cannot maneuver efficiently.

We Recommend the Following


  • If you have a driveway, use it. The more cars off the road, the better and faster the operation can proceed, and the less likely it is that a vehicle will be plowed in, splashed by salt spray, or become the victim of a collision.
  • We ask that all portable basketball hoops (backstops) are to be removed from the Harford County right of way in order to help expedite our snow removal operation.
  • To help avoid the frustration that occurs when a snowplow covers your driveway with snow after you have shoveled, stand facing the road and shovel snow to the right into the yard instead of into the road.
  • If you do not have a driveway, park on the even numbered side of the road in even years, and odd numbered side of the road in odd years, as close to the curb as possible. Move to the other side of the road after the plow has cleared it. Example: The 2019-2020 season was an even year, and the 2020-2021 will be an odd year.

What You can Expect When it Snows


  • 0-6 Inches: It takes about 8 - 16 hours following the end of a 0 - 6 inch snowfall to plow and/or treat every county road once.
  • 6-12 Inches: After a 6 - 12 inch snowfall, you can expect county roads to be cleared within 24 - 36 hours. At that time, 1 pass should have been made through all county roads.
  • 12-18 Inches: After a 12 - 18 inch snowfall, our crews will complete the work in about 35 - 40 hours.
  • 18-24 Inches: After an 18 - 24 inch snowfall, you can expect one pass to have been made through all county roads in 48 - 72 hours.
Please be patient! Roads are plowed according to their priority and reviewed at the end of each season. Snow fighters work around the clock until all 1,075 miles of county maintained roads are passable. We will use a force of approximately 201 employees and 158 pieces of snow removal equipment for routine snow plowing and we have available 20 additional pieces of equipment for use when conditions dictate. We store 20,000 tons of salt to get the job done.
