95. The embankments of a road that crosses a watercourse must be stabilized between the banks up to above the conduit or the arch, during the construction, improvement or repair of the road, with a geotextile membrane covered with riprap or a retaining wall.
The slope of the embankments located between the banks and above the conduit or the arch and the slope of the embankment located within 20 m of the watercourse, measured from the upper limit of the bank, must be reduced to a ration of 1 (V):1.5 (H) and the embankment must be stabilized using the usual techniques, such as those referred to in the second paragraph of section 73. The reduction of the slope is not required if the embankment is stabilized with a geotextile membrane covered with riprap or a retaining wall.
