Our Dust Abatement Program provides an option for gravel road residents who are troubled by the amount of dust generated by traffic on the roadway during the dry summer months. This program is available for roads maintained by the county as well as roads known as "local access roads" which are public roads yet are maintained by local residents. For residents living along private roads, please contact a contractor directly to inquire about cost and availability for your particular situation.
We accept requests every year from residents to apply dust control product to roads for dust abatement. On county-maintained roads, the county shares in the cost of this program due to a partial cost savings related to a decreased need to grade the road during the summer months. On local access roads, the full cost is paid by the residents. Prices and details can vary each year.
Please contact our office if you would like a current packet of information on this program or to be placed on our mailing list for the upcoming year. In general, we mail packets of information to interested parties in March or April each year. Payments are received prior to a set deadline to allow us adequate time to make all the plans needed for application of the product on the road. The minimum length of treatment is 500 feet. Typical application width is 16 feet.
Application of the product is usually done in the late-spring or early summer. Steps related to dust abatement application include:
- Some basic preparation of the road surface is usually required ahead of time, such as grading. This is normally done within one to two weeks of the anticipated application date.
- The application of the product can vary between a single application and a double application which is done with a variable amount of time in between. This variability is determined by several factors, including the aggregate surface being treated.
- During and after application, the road will be closed for up to four hours to apply the product and let it set up. While emergency vehicles could use the road if needed, it is best if residents refrain from driving on the road during this closure period.
The duration and degree of effectiveness in reducing dust is dependent on a lot of variables. Primarily high volumes of traffic, high speeds, and heavy truck traffic can decrease effectiveness. Additionally, if the road needs to be regraded due to potholes or excessive roughness the dust abatement qualities of the application will decrease substantially.
