Road and Trail Flashcards
study and make readings more manageable
What are landings?
Where logs removed from a unit can be loaded onto a harvest truck
What is a saddle and why are they useful for roads?
- A saddle is a low point along a ridge
- You can access both sides of a ridge when you have your road along a saddle
What are benches?
Natural breaks in the slope that can be used for landings
Why build roads on rock outcrops?
because even though it can be very expensive if it can be used to create surfacing material it could be worth it.
Why should you not build on slumps and slides?
it can be significantly more difficult due to the unstable terrain and lack of slope stability.
Why should wet spots be avoided?
Anything that exposes subsurface water sources should be avoided due to the increased chances of higher maintenance in the future.
What to consider during potential stream crossings?
- What stream type is present
- How to cross it (bridge/pipe)
- Cost of crossing it
- Forest practice rules
etc…
Why should sharp turns be avoided?
Potential issues for log trucks going up and down trails
What are areas of surplus excavation?
Dump spots
What are crowned roads?
roads that are higher in the middle and slope out on either side the let water drain off.
What are insloped roads?
Roads that lean towards the slope that they have been built into to let the water drain. With a ditch to catch and transport the water.
What is an outsloped road?
a road that leans away from the slope it has been cut into. There is no ditch necessary bit in areas with high water flow there is an increased risk of the road being washed out.
What is a full bench road?
A road built into a slope that is 65% or more that excavates part if the slope out cuts a ditch alongside the road and adds fill onto the road. This is the most expensive and takes the most planning.
What is the minimum road width?
14ft
