COUNTY OF TEHAMA
DEPARTMENT OF PUBLIC
SECTION V – Operations
Low volume dirt and gravel roads
shall be graded at least two times per year.
Roads shall be graded during spring while sufficient moisture is in the
soil to grade out potholes and wash boarding, and to mix dirt with the gravel
for sufficient fine materials so that effective compaction may be obtained, and
so that a hard crust may be developed to provide a long wearing surface. These roads shall again be graded during fall
to prepare the roads and drainage ditches for winter weather. If summer selective grading has moved the
gravel to the roadside, this gravel shall be bladed back onto the road surface to
develop a crown for winter conditions.
During winter months, additional gravel may be placed on roads at
locations needed to provide adequate traction.
Selective grading shall be done at times and locations as necessary to
correct drainage problems, potholing or wash boarding.
