Dust Control

Dust Control Cost Share Program

The Board of County Commissioners approved a dust control cost sharing program for 2020 where a product is sprayed onto the gravel road in front of your home to help reduce the dust. To be eligible for this program, residents must be living on a gravel road in the unincorporated area of Johnson County. The program will cover a 400 foot treatment area and the county will pay for half of the cost to apply the product and the resident will pay the other half. Additional footage must be paid by the resident at 100%. This will be a one year trial period to assess the program's effectiveness and cost. The program will be limited to the first 100 people who sign up.

How does dust control work?

Johnson County uses a magnesium chloride dust control treatment. The product is sprayed onto the road, creating a cement-like surface. While the road will still look like a gravel road, the dust created by traffic will be significantly reduced. After application and during periods of rain, the road will be a little wet and sticky. During these times, drive slowly to reduce the amount of material kicked up onto your vehicle. Effectiveness and duration of the magnesium chloride treatment varies with traffic and weather conditions. It is our hope that the treatment will last through the dry summer months. Public Works will attempt to minimize maintenance of the dust control areas to maximize its life and effectiveness. However, if road conditions require maintenance, Public Works will maintain the road as required which can affect the performance of the dust control. Annual reapplication is recommended.

Life on a gravel road

As Johnson County continues to experience rapid growth, many residents are seeking to live the “country life” in the more rural parts of the county, many of which are accessed by gravel roads. About 135 miles of gravel roads remain in the county, much of which was intended for low-volume farm use. As residential areas continue to spread across the county, many are now located on these gravel roads. If you have not previously lived on a gravel road you may not be aware of the issues that come with an unpaved road. You can encounter:

  • Road dust everywhere – in the air, on your vehicle and in your house
  • Mud and loose material – after it rains, surface material may be thrown off tires and stick to vehicles
  • Quickly changing conditions and frequent pot holes, rutting, and washboarding 
  • Snow and ice cannot be treated the way they can on asphalt roads. Gravel roads are often snow packed and ice covered for extended periods during the winter
