WATERBAR CONSTRUCT/ON NOTES:

WATERBARS ARE USUALLY CONSTRUCTED BY

ANGLE DOZERS. WATERBARS SHALL HAVE A

CLEAN OUTLET AND BE CONSTRUCTED SO THEY

WILL NOT FAIL THROUGH ALL WEATHER USE.

2. THE WATERBAR DRAIN LINE SHALL BE SKEWED

5· TO 25".

3. WATERBARS SHALL BE CONSTRUCTED SO THAT

ORA/NL/NE EXCAVATION IS APPROXIMATELY 6"

INTO SOLID SOIL AND THE TOP OF COMPACTED

WATERBAR IS 12" ABOVE THE ORA/NL/NE.

4. THE TOTAL LENGTH OF THE WATERBAR SHALL

NOT BE LESS THAN SIXTEEN FEET (16') .

5. CROSS SLOPE OF THE DRAIN LINE SHALL BE

EQUIVALENT TO TO THE CROSS SLOPE OF THE

ROAD PLUS TWO PERCENT (2%).
