73. The excavated soils and road embankments must be stabilized without delay during the construction, improvement or repair of a road, by means of soil stabilization techniques as much as possible in harmony with the natural setting of the environment, in places where the erosion of the road could bring sediments into an open peat bog with a pond, a marsh, a riparian swamp, a lake or a watercourse.
Stabilization techniques are, in particular: stabilization with vegetation, riprap and the construction of a retaining wall. A geotextile membrane must be placed under the riprap or retaining wall if there is a risk of bringing sediments into the environments referred to in the first paragraph.
