Snow & Ice Removal

Johnson County Public Works is responsible for snow and ice removal in the unincorporated area.

Our mission during winter weather is to achieve and maintain safe traffic movement on public roadways, within a reasonable period of time. We are committed to providing effective and efficient winter maintenance services during and immediately following each winter event. Operational procedures, policies, and extensive planning all play a key role in upholding our commitment and honoring our mission.

The decision to initiate snow and ice removal operations is based on factors such as snow accumulation, or expected accumulation, icy conditions which affect travel, and time of snowfall in relation to traffic volumes. The use of weather reports from the National Weather Service, review of local television satellite storm tracking and existing road condition reports are all used to determine the appropriate scope of operations.

The County's roadways are divided into hard surfaced arterial roads, collector streets, residential streets and gravel roads. Arterial roads and those with hills, bridges, shaded driving surfaces or super elevated curves receive first priority. After arterial roads are cleared, crews will begin on collector roadways and residential streets. Due to the logistics of moving motor graders to outlying areas of the county, gravel roads will only be plowed when snow accumulations exceed 3 inches.

Each winter event will vary in size and complexity, and while we strive to work as safe and efficient as possible, we understand there will be complaints or requests for additional services. If, after 24 hours, you feel that we may have missed your area, please submit an online Request for Service or call Public Works at 913-715-8300. Damage to private property, most commonly mailboxes, should also be reported to our office.


For snow and ice removal within city limits, please contact the specific city.
For snow and ice removal on a highway, please contact KDOT.


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

Chip Seal

Chip Seal

As part of the County's asphalt maintenance program, Public Works annually chip seals some of the asphalt roads in the unincorporated area.  Chip seal is a highly cost effective way to maintain, protect, and extend the life of an asphalt road.  The Public Works department first implemented the chip seal program back in 2007, and each year chip seals an average of 30 miles.  By self performing the chip seal, the cost is about $12,000 per mile versus an overlay cost of about $100,000 per mile.  


The Process

A thin film of heated asphalt liquid is sprayed on the road surface, followed by the placement of "chips" (small rocks).  The chips are then compacted to orient them for maximum adherence to the asphalt and the excess chips are swept from the surface.  A few days following the chip seal application, traffic will notice loose chips on the road.  This is a normal part of the process and traffic will further help to embed the chips into the asphalt.  While the road "cures" over the next couple of weeks, loose chips may be swept up again and new pavement markings are painted.


Maintain, Protect, and Extend The Life

Chip seal is a common preventive maintenance activity, with many state road agencies and cities across the nation using it.  It helps to protect the pavement from the effects of sun and water, increases skid resistance, and fills small cracks and other surface defects.  Many studies about the performance and effectiveness of chip seal have been done and chip seal is agreeably one of the most economical treatments for paved roads.  Chip seal extends the life of an asphalt pavement by up to 7 years, thus saving County taxpayers money.
