Unsealed Roads
Grading
Grading frequency for each road is set depending on the hierarchy classification of the road, with the busiest roads graded more often.
| Hierarchy | Base grading |
|---|---|
| Major | 8 grades per annum |
| Intermediate | 4 grades per annum |
| Minor | 3 grades per annum |
| Lane | 2 grades per annum |
| Track | 1 grade every 15 months |
Some roads are graded more frequently than this due to the topography or traffic volumes on the road.
There are three different grading areas, and each year a plan is prepared for each area. The plan takes into account the number of times each road should be graded and when the grader will be within the area.
The grading plan is subject to change depending on weather and road condition, and other activities on the network such as events.
Gravelling
Over time unsealed roads experience gravel loss and re-gravelling is required to restore a suitable driving surface.
A list of roads that require gravelling is prepared every three years. There are more roads that require gravelling than there is funding available to do. The list of road for gravelling has to be prioritised to keep within the available funding.
The priority is set based on the hierarchy classification of the road, the condition of the road, and consideration of safety and accessibility issues.
Sealing Unsealed Roads
Council does not currently have any funding set aside in the 10-year plan for sealing unsealed roads.
Dust Suppression
Dust Suppression Sealing
Since 2008 Council has been applying eco seal to 100m sections of gravel roads where there is a house located within 100m of a gravel road as a dust suppressant.
Please find below a link to the roading policy. Section 28 defines dust suppression on the network.
