Granular roads are graded 4 times per year or more depending upon the impact that the weather and traffic has had upon the condition of the roadway. Early spring grading is light in nature to rid the road of the pot holes. Late spring grading is to shape the road and prepare it for dust suppression and base stabilizing calcium chloride applications. If all goes well, there will be a late summer grading and finally a fall grading to prepare the roads for winter travel. In general, you cannot grade when the road is wet or about to be wet.
Shouldering is performed on an as-needed basis in response to heavy runoff caused by spring thaw or heavy precipitation and related washouts.
Calcium Chloride is applied to freshly graveled roads and newly graded roads from May to June. This activity reduces the dust generated from traffic and helps maintain the graded shape of the road in the summer months.
Culverts that direct drainage to the opposite side of the road are replaced when they have corroded and no longer drain properly, and may also be unable to properly support the compressive forces of road traffic.
Entrance culverts on driveways are the responsibility of the land owner.
