Black Hawk County policy allows residents to apply approved dust suppressing materials to gravel roads. Residents are responsible for all payments to the applicator. There is no charge for the permit.
If you plan to have a dust suppressant applied to the road, please contact an approved vendor immediately. For a list of approved vendors and more information on the county’s dust control policy see “Dust Control” online at
The deadline to sign up is Wednesday, April 15, 2015, unless an earlier deadline is stated by the vendor.
If you have questions, please call the Black Hawk County Engineer’s Office at 319-833-3008.
