Before placing embankment, loosen the roadbed by ripping or scarifying to the depth of 12 inches. Pull all embankments and apply the material to contour or fill ditches; or haul it to designated areas. Construct waterbars as shown on the plans. Scatter any available slash on obliterated roadway. Keep excavated material within the original roadway limits unless otherwise shown on the plans.

(b) Method 2. Shape the roadway to drain water. Fill ditches, outslope the roadbed and loosen the roadbed by ripping or scarifying to the depth of 12 inches to provide a seedbed and promote establishment of vegetation. Scatter any available slash on obliterated roadway.

Construct waterbars as shown on the plans. Effectively close the road by method shown on plans.

230.02 Brushing. Cut all brush and small trees (6 inches diameter, or less, at the point of cut) inside the brushing limits and outside the roadbed no higher than 4 inches above ground level (6 inches for machine brushing). If rocks or other obstructions are encountered, cut no higher than

6 inches above the obstruction. Limb live trees with a diameter larger than 6 inches to provide a clear height of 18 feet above the road surface.

Cut all brush and trees located on the roadbed as nearly flush to the road surface as possible so stumps will not become a hazard to vehicle tires.

230.03 Windfalls. Limb windfalls lying within or across the brushing limits, cut off at the top of the existing cut slope or 5 feet from the shoulder on the fill slope. Dispose of windfall material as slash.

230.04 Road Junctions. Do not deposit brushing debris on the roadway of adjoining roads.

230.05 Slash Treatment. Scatter slash outside the brushing limits without damaging residual trees. Slash is defined as any material that has a length greater than 36 inches or a diameter greater than 2 inches at any point. Do not deposit material in streams, streambeds, culvert inlets or outlets, drainage ways, or cattle guards.

230.06 Acceptance. Roadside brushing will be evaluated under Subsection 106.02.
