NOTE: IN THOSE AREAS WHERE THE EXISTING ROAD, AFTER

PLACING THE ADDITIONAL XXXX WIDTH OF AGGREGATE IN

TURNOUT AREAS AND SECTIONS REQUIRING CURVE

WIDENING, PLACE ADJACENT TO CENTERLINE LIFT AND

COMPACT TOGETHER.

NOTE: OUTSLOPED ROADS SHOULD BE USED WHEN ROAD

GRADES ARE GENTLE TO MODERATE (0% TO 8%) AND WHERE

CUTSLOPES ARE DRY. OUTSLOPED ROADS SHOULD BE

CONSTRUCTED WITH ROLLING DIPS FOR DRAINAGE. THERE

SHOULD BE NO DITCH ON THE INBOARD SIDE OF THE

OUTSLOPED ROAD.

NOTE: INSLOPED ROADS SHOULD BE USED WHEN ROAD

GRADES ARE MODERATE TO STEEP (6% AND UP) AND WHERE

TERRAIN MAY BE STEEP OR SLIPPERY. INSLOPED ROADS

ARE ALSO IDEAL FOR HIGHLY ERODIBLE AREAS. EXTRA

ATTENTION SHOULD BE PAID TO ESTABLISHING DITCHES AND

DRAINAGE FOR INSLOPED ROADS.

3. INSPECT SILT FENCES AFTER EACH RUNOFF EVENT AND

IMMEDIATELY REPAIR ALL EROSION ALONG EDGES AND BOTTOM.

4. ACCUMULATED DEPTH OF SEDIMENT SHALL NOT EXCEED ONE

HALF OF THE ORIGINAL HEIGHT OF THE SILT FENCE.

5. IN AREAS DESIGNATED FOR BRUSH BARRIERS, LIMIT CLEARING

TO TREES, SHRUBS AND PLANTS LESS THAN 4" IN DIAMETER.

GRUBBING SHALL NOT BE PERFORMED IN THOSE AREAS.

6. BRUSH BARRIER SHALL BE CONSTRUCTED APPROXIMATELY

PARALLEL TO ORIGINAL GROUND CONTOUR. USE

WELL-INTERMINGLED MASS OF BRUSH, TRESS, TRIMMINGS ETC.

BARRIER SHALL BE POROUS ENOUGH TO ALLOW WATER TO

FILTER THROUGH. SECURE BY PLACING MATERIAL (TREES, LOGS

ETC) ON TOP OF AND THROUGHOUT THE BRUSH.

7. ADJOIN BRUSH BARRIER WITH ROADWAY SLOPE ON THE LOW END

AS NEEDED TO CONTAIN SEDIMENTS.
