Beginning at the lowest point just above the Q2 elevation, drive wooden stakes vertically 3 to
4 feet into the ground. Stakes should be spaced 1 to 1 ½ feet apart as shown in Figure 15.8.
Place initial layer of branches 4” to 6” thick in the bottom of the hole, between the vertical stakes
and perpendicular to the slope face. Branches should be placed in a crisscross pattern with
buds generally pointing toward the slope face. Basal ends of the branches should touch the
undisturbed soil at the back of the hole.
Cover each layer of branches with a layer of compacted soil to ensure soil contact with the
branches.
Subsequent layers of branches should be installed with the basal ends lower than the growing
tips.
The final layer should conform to the existing slope.
