Note: Roadside clearing limits shall be to the top of the backslope and toe of the fillslope on both sides of the traveled way. Clearing shall include trees up to 6” dbh. Trees larger than 6” dbh, shall be limbed to a clear to a height of 14’ minimum. Clearing height is 14’ minimum.

The clearing width at all roadside ditches shall be to the top of the backslope.

Clearing limits for brushing all leadoff ditches is 12’as shown on the drawings. Brush from the leadoff ditches may be cut and placed at the outlet to the leadoff ditch as an energy dissipater with brush not to exceed 18” height above the ground.

Clearing shall be accomplished by either hand clearing then processing the brush material through a chipper or by a roadside brushing machine designed specifically for roadside brushing and approved by the Contracting Officer’s Representative. Chips shall be sidecast evenly and not piled.

Tree limbs shall be cut back as close to the bole of the tree as practicable.

All road reconstruction work shall be approved in writing by the Contracting Officer’s Representative prior to the placement of the aggregate surface course.
