Clearing and Grubbing of the Road Construction Area
Preparing the road right-of-way or construction area is referred to as clearing and grubbing. During the clearing phase, trees are felled. Grubbing refers to the clearing and removal of stumps and organic debris. Trees should be felled and cleared a minimum of 1 to 3 m from the top of the cut or toe of the fill (Figure 105). The logs can be decked outside the construction area (Figure 105, B to E) or skidded away.

Stumps may be left between D and E. Organic debris and removed stumps are placed in windrows at F to serve as filter strips (see Section
