Chapter V – Roads, sandpits and forest infrastructures
Division II – Roads
§4. Stabilization of excavated soils and road embankments and diversion of runoff

Section 76

During the construction, improvement, repair or maintenance of a road, the water flowing at the foot of the embankments of a road, other than a felling or hauling trail, other than a trail not intended for motorized all-terrain vehicles or other than a winter road, must be regularly diverted outside the right-of-way of the road towards vegetation areas located more than 20 m from an open peat bog with a pond, a marsh, a riparian swamp, a lake or a watercourse.

The maximum distance in meters to be respected between the diversions is calculated by dividing the number 500 by the percentage, in whole number rounded to the closest unit, of the road slope, or is calculated by any other technique ensuring that the diversions are in a sufficient number and laid out so as to prevent the erosion of the road.

Objectives

  • To preserve the integrity of an aquatic, wetland or riparian environment
  • To avoid carrying sediment into an aquatic, wetland or riparian environment
  • To ensure the lifespan of a road, bridge or culvert

Additional information

The maximum distance in metres to be respected between the diversions is calculated by dividing the number 500 by the percentage of the road slope as a whole number rounded to the closest unit.

Maximum distance between diversions, in meter, equal : 500 divided by the percentage of road slope as a whole number, rounded to the nearest unit

For example, if the road slope is 9.6%, the slope percentage as a whole number rounded to the nearest unit is 10. The maximum distance to be respected between the diversions is therefore 50 m, or 500 ÷ 10.

The distance between the diversions may also be calculated using a different technique, to make sure they are sufficient in number and laid out so as to prevent the erosion of the road. While this is not mandatory, we recommend that appropriate techniques be agreed upon with representatives from the regional office of the Ministère des Forêts, de la Faune et des Parcs before beginning work to divert water flowing at the foot of the embankment of a road.

In the event that an alternative method is chosen, it must meet the following objectives:

  • To preserve the integrity of an aquatic, wetland or riparian environment
  • To avoid carrying sediment into an aquatic, wetland or riparian environment
  • To ensure the lifespan of a road, bridge or culvert

Where the slope of the road to be built or improved is greater than 9% and the foot of the slope is less than 60 m from an open peat bog with a pond, a marsh, a riparian shrub swamp, a lake or a watercourse, the slope of the embankment and the clearing of the road must be reduced to a ratio of at least 1 (V): 1.5 (H) and the embankment must be stabilized using the techniques mentioned in section 73.   This paragraph does not apply to a person who, in accordance with section 41 of the Sustainable Forest Development Act This link opens a new window (chapter A-18.1), was authorized by the Minister to build or improve a road meeting other conditions, or to a person who has obtained such an authorization by a forestry permit or a contract or agreement entered into under that Act.

  • To avoid carrying sediment into an aquatic, wetland or riparian environment
  • To ensure the lifespan of a road, bridge or culvert

Objective

  • To protect forest resources during specific road, bridge or culvert construction or improvement work

Explanations

A person authorized by the Minister in accordance with section 41 of the Sustainable Forest Development Act This link opens a new window may build or improve a road on conditions other than those indicated in the third paragraph of this section concerning reduction of the slope of the embankment, the clearing of the road and stabilization of the embankment. The Minister may grant authorization, specifying the authorized replacement standards and setting conditions to be met when carrying out the work.

Additional information

A person wishing to obtain authorization for this must apply to the regional office of the Ministère des Forêts, de la Faune et des Parcs This link opens a new window (in French only) by completing the form provided for that purpose. The application must describe the situation that justifies completion of the work in accordance with standards different from those enacted in the Regulation. It must also propose replacement measures that will be implemented to achieve the objectives of the regulatory standards from which a departure is requested. Where the proposed replacement standards fall within the approval framework, authorization may be granted along with conditions that must be met when carrying out the work.

In the case of the repair of a road whose slope is greater than 9% and whose foot of the slope is less than 60 m from an open peat bog with a pond, a marsh, a riparian shrub swamp, a lake or a watercourse, the slope of the embankment and the clearing of the road must be stable and not allow the carrying of sediments into the environment to be protected.
