M1 |
Road construction must be carried out in accordance with the road plan, subject to changes necessitated by site conditions and approved by the designer [see General Road Construction Practices]. |
Legislation supported: FPPR section 78: minimize clearing width |
|
B1 |
Minimize the clearing width, while accommodating the topography, user safety and operational requirements [Establishing Clearing Widths]. |
Legislation supported: FPPR sections 37, 38, 57, 59, 69, 70, 72, 106.2: do not cause sediment transport through mass wasting processes that will impact user safety or have a material adverse effect on forest resources |
|
B2 |
Do not deposit debris resulting from grubbing and stripping within the clearing width in areas where the debris could have a material adverse effect on forest resources and other values [see Disposal of Debris]. |
B3 |
In areas of moderate to high landslide potential, remove all organic debris from within the road prism width [see Disposal of Debris]. |
B4 |
Locate disposal sites and place debris at a disposal site to ensure that activities do not cause a landslide, gully processes on the Coast, or uncontrolled erosion and sediment transport that have a material adverse effect on forest resources and other values [see Disposal of Debris]. |
B5 |
To maintain slope stability in areas having steep slopes or unstable (or potentially unstable) terrain, consider applying full bench and partial bench construction techniques [see Full Bench]. |
B6 |
Ensure that rock drilling and blasting techniques minimize the potential for landslides or slope instability [see Rock Excavation]. |
B7 |
Shut down road construction work before slope stability is in question, or landslides occur [see Shutdown Indicators]. |
Legislation supported: FPPR section 39: maintain surface drainage patterns |
|
B8 |
To maintain surface drainage patterns, keep water in its own drainage area, unless moving it to another area is necessary to avoid unstable or sensitive soils [see Maintaining Surface Drainage Patterns]. |
Legislation supported: FPPR section 50: no construction in riparian management areas, except as provided |
|
B9 |
B9. Do not locate borrow pits or disposal sites in a riparian management area [see Location of Disposal Sites]. |
B10 |
Ensure that there are no subgrade construction works within a riparian management area, unless otherwise exempted from this requirement by regulation [see Riparian]. |
Legislation supported: FPPR section 54: no fan destabilization on the Coast |
|
B11 |
Ensure that road construction works do not cause fan destabilization on the Coast that will result in material and adverse effects on other resources [see Fan Destabilization]. |
Legislation supported: FPPR section 55: protect stream channel and banks |
|
B12 |
Ensure that the disturbance to the stream channel and the stream bank at the crossing are mitigated to the extent that the original conditions are reasonably restored. Also, ensure that despite the works at the crossing, the stream banks above and below the crossing are protected. Ensure that the disturbance to the stream channel and the stream bank at the crossing are mitigated to the extent that the original conditions are reasonably restored. Also, ensure that despite the works at the crossing, the stream banks above and below the crossing are protected [see Culverts]. |
B13 |
Use culvert outlet protection where discharge velocities and energies at the outlets of culverts, conduits or channels are sufficient to erode the immediate downstream reach [see Culverts]. |
Legislation supported: FPPR sections 56 and 57: protection of fish passage and fish habitat |
|
B14 |
Ensure that any culverts constructed on a fish stream do not impede fish passage or harmfully alter fish habitat [see Culverts on Fish Streams]. |
B15 |
Ensure that roads on fans are constructed to account for identified hazards on a fan [see Fan Destabilization]. |
Legislation supported: FRPA section 46: protection of the environment and FPPR section 59: protection of water quality |
|
B16 |
To minimize sediment delivery to streams, do not discharge the water conveyed in ditches and cross-drain culverts directly into streams [see Maintaining Surface Drainage Patterns]. |
B17 |
For snow and winter roads, do not mix soil with snow in the riparian management area of stream crossings [see One-Season]. |
B18 |
Ensure that debris is placed at disposal sites so as to protect against sediment transport that will have a material adverse effect on forest resources and other values [see Disposal of Debris]. |
B19 |
When constructing permanent roads, minimize the placement of snow, ice, and frozen material in the road fill [see Winter Construction]. |
B20 |
When constructing fords, consider:
[see Ford Construction] |
B21 |
To minimize sediment transport away from the road prism and disposal sites, consider using sediment control techniques [see Sediment Control]. |
B22 |
Ensure that roads on fans are constructed to account for identified hazards on a fan [see Fan Destabilization]. |
B23 |
Surface the subgrade with pit-run gravel or crushed rock aggregate where subgrade material is highly erodible and needs to be protected from water or wind action [see Surfacing]. |
B24 |
Determine when forest road operations are to be shut down because the works are causing, or may imminently cause, environmental damage [see Shutdown Indicators]. |
Legislation supported: FPPR sections 60, 62: no construction near licensed waterworks in community watersheds or springs in a community watershed | |
B25 |
Unless there is an exception in accordance with FPPR, ensure that the road is constructed so as not to damage a licensed waterworks and to achieve at least 100m distance from any such waterworks or springs in community watersheds [see Licensed Waterworks]. |
Legislation supported: FPPR sections 69, 70: general wildlife measures, and resource or wildlife habitat features |
|
B26 |
Ensure that a road is constructed in accordance with any general wildlife measures that may be in place (as identified in the road layout process), and the construction activities do not damage and resource or wildlife habitat features [see Wildlife]. |
Legislation supported: FPPR section 72: roads and structures are safe for industrial users |
|
B27 |
Construct turnouts and widenings at locations and to specifications in accordance with the road design to allow safe passage of expected vehicles types on single lane roads [see Turnouts]. |
B28 |
Should a ford become unsafe for traffic during high water, take measures to warn and exclude users for that period [see Ford Operating Constraints]. |
Legislation supported: FPPR section 76: culvert materials | |
B29 |
Ensure that any permanent culvert materials are fabricated in accordance with the current Canadian Standards Association specifications [see Road Drainage]. |
Legislation supported: FPPR section 40; revegetation |
|
B30 |
To minimize surface soil erosion after road construction on all soils exposed that are subject to weathering, cover them with grass and legume vegetation [see Soil Erosion]. |
Legislation supported: FPPR sections 37, 38, 39, 40, 50, 54, 55, 56, 57, 59, 60, 62, 69, 70, 72, 76, 78, 84, 106.2: all road-related items |
|
B32 |
Ensure that the necessary steps in the road construction processes were undertaken and issues addressed [see Project Tracking Checklist] |
M2 |
The Coordinating Member must sign (and seal as appropriate) the Road Project Assurance Statement (PDF). |
B33 |
Ensure that there is a field inspection to monitor the completeness of the professional certification and to incorporate as-built information into the applicable data base [see General Road Construction Practices]. |
B34 |
For those roads identified as becoming FSRs after construction:
