Dust Control

Dust Control Cost Share Program

The Board of County Commissioners approved a dust control cost sharing program 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%.

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.
