Importance of RoadingImportance of Roading
• Code of Forest Practice
– Poorly designed or maintained timber production
roads have the potential to create significant
environmental impacts, particularly on water
quality and river health.
– Plans for roads must be based on field surveys to
ensure that all environmentally sensitive locations
are identified and appropriate design and
construction techniques are adopted.
• VicForests Roading Instruction
– The cost of providing road works is significant
and is therefore an important business process that
requires thorough and appropriate financial and
environmental planning and approval's processes.
