Will my dust control still be effective after they blade the road?: Yes. They can blade lightly through chloride and lignin without damaging its effectiveness. We only blade through the dust control if there are holes that need to be filled. Any dust control areas on the road need to be marked so workers know the dust control agent is there when they come through with the blade.

3. If the seal coat on my road is still good, can I keep it?: Yes. If you would like someone from the Secondary Road Department to check it, you need a $50.00 non-refundable retain permit. The district foreman will review the seal coat. If the seal coat is in good shape, the permit will allow you to obtain patch material at a County shop through October 31st. If the seal coat is not in good shape, we will contact you so you can sign up for something new.
Permit to Retain

4. Is the retain permit refundable if my seal coat can not be retained?: No. The permit fee pays for the department to send someone to go to the property and check the condition of the seal coat section. The permit also allows you to pick up patch mix from a county shop to fill potholes within your dust control section.

5. I rent a house on a county road and would like to put dust control down. Can I put dust control down even if I don't own the property?: Yes. You can pay to put dust control on any county road.

6. I want to put dust control in front of my property but it will also be in front of a neighbor's house. Can I do that?: Yes. It is a County road and you can pay to put dust control on any County road you want. What you will want to do is to make sure they don’t pay for dust control for the same portion of the road, as well. If they also want dust control, you can get together and share the cost or lengthen the distance of dust control.

7. Will my dust control still be effective after they blade the road?: Yes. They can blade lightly through chloride and lignin without damaging its effectiveness. We only blade through the dust control if there are holes that need to be filled. Any dust control areas on the road need to be marked so workers know the dust control agent is there when they come through with the blade.

8. Does the County fill gaps between dust control areas?: No, we don't fill the gaps. If you have neighbors that are also getting dust control, you might want to talk to them about distances to ensure there are no gaps.
