Deactivating and Rehabilitating Roads
The following section summarizes the recommended best management
practices for deactivating and rehabilitating roads.
As these are only brief summaries, you should also check
out more detailed information in the Karst
Management Handbook for British Columbia.
Best management practices for all vulnerability categories
The following best management practices are recommended:
- Consult the local Forest Service district office to discuss
access management with regard to deactivating roads.
- Remove or frequently breach windrows on the outer edge
of temporarily deactivated roads.
- Use strategies to prevent impacting karst features during
temporary deactivation (e.g., water bars, cross-ditches,
inslopes or outslopes).
- Use strategies to prevent sedimentation when permanently
deactivating roads (e.g., armouring drainage ditches).
- Do not use quarries as storage sites for logging debris/wood
waste, refuse, petroleum products, etc.
- Deactivate quarries upon completion of operations.
- Take measures to make deactivated quarries inaccessible to
the public (e.g., berms, waterbars).
- Restore natural surface drainage patterns as much as possible
to maintain the quantity and quality of subsurface flows.
- Avoid road rehabilitation during sustained or heavy rainfall.
- Avoid road
deactivation or rehabilitation when
disturbances to roadbeds may be detrimental to karst values
in the area.
- Keep the wheels or tracks of equipment at least 5 metres from
the edge of roadside karst features. If not possible, keep wheels
or tracks parallel to the edge of features.
- Avoid introducing soil or bedding materials into karst features.
- Complete rehabilitation operations with sufficient time to
allow for adequate revegetation before the wetter months of
