GENERAL NOTES
1) ROADS SHALL BE CONSTRUCTED IN ACCORDANCE WITH THE SPECIFICA-
TIONS, SHEET 10, SECTION 2.0
2) ROAD CUTS SHALL NOT BE STEEPER THAN 1.25(H):1(V), EXCEPT AS
SPECIFIED IN NOTE 11. EMBANKMENT SLOPES SHALL NOT BE STEEPER
THAN 2(H):I(V).
3) BETWEEN STATIONS 0 +00 AND 29 +50, THE HEIGHT OF THE ROAD CUTS
IS NOT LIMITED. BETWEEN STATION 29 +50 AND THE END OF THE
ROAD, THE HEIGHT OF THE CUT SHALL BE LIMITED TO 20 FEET BY THE
CONSTRUCTION OF RETAINING WALLS SUCH AS HILFIKER WALLS OR
EQUIVALENT, EXCEPT AS SPECIFIED IN NOTE 11.
4) RETAINING WALLS AND ROAD CUTS WILL BE SHOWN IN CONSTRUCTION
DRAWINGS.
5) DITCH RELIEF DISCHARGE POINTS SHALL BE LOCATED AS SHOWN ON
SHEET 7 OR AS MODIFIED BY CONSTRUCTION DRAWINGS. DISCHARGE
POINTS SHALL BE RIPRAPPED AND MAINTAINED AS REQUIRED TO P E-
VENT UNDUE EROSION.
6) ROAD DITCH RELIEF CULVERTS C -2 THROUGH C -7 SHALL RE INSTALLED
AT LOCATIONS SHOWN ON SHEET 7 OR AS MODIFIED BY CONSTRUCTION
DRAWINGS OF 18 -INCH DIAMETER CORRUGATED METAL PIPE.
7) THE LENGTHS OF THE CULVERTS SHALL BE DETERMINED ACCORDING TO
THE WIDTH OF THE ROAD FILL AT EACH LOCATION. EACH END OF THE
CONDUIT SHALL EXTEND A MINIMUM OF 1 FOOT BEYOND EACH END OF
THE FILL. THE FILL BANKS ADJACENT TO THE CULVERTS SHALL BE
RIPRAPPED FOR EROSION PROTECTION. ALL CULVERTS SHALL HAVE A
MINIMUM 1 -FOOT COVER. ALL FILL AROUND CULVERTS SHALL BE
COMPACTED AS SPECIFIED ON SHEET 10, ITEM 3.3. OUTLETS OF ALL
CULVERTS SHALL BE RIPRAPPED AND MAINTAINED AS REQUIRED TO
PREVENT UNDUE EROSION.

8) RIPRAP AND /OR STRAW BALE CHECK STRUCTURES AND SEDIMENT FILTER
STRUCTURES WILL BE PLACED IN DITCH ON STEEP PORTIONS OF HAUL
ROAD TO SLOW VELOCITIES AND MINIMIZE SEDIMENT MOVEMENT.
9) CULVERT INLET STRUCTURES SHALL BE SUITABLY CONSTRUCTED TO
PREVENT CLOGGING AND TRANSMIT DESIGN FLOWS.
10) CULVERTS SHALL BE INSTALLED AT ANGLES GREATER THAN 30 DEGREES
DOWNSTREAM FROM THE PERPENDICULAR TO THE HAUL ROAD. CULVERTS
ON LONG STEEP SECTIONS OF THE ROAD SHALI. BE PLACED AT 45 DE-
GREES TO THE ROADWAY AXIS.
11) ROAD CUT SLOPES CAN BE STEEPENED TO SLOPE 1:1 (45 DEGREES) AND
MAXIMUM CUT HEIGHTS INCREASED TO 30 FEET AT CUTS EXCAVATED AT
SLOPE 1:1.25. INCREASED PROBABILITY OF POTENTIAL FAILURES IS
TO BE EXPECTED, AND MONITORING OF SLOPES WILL BE REQUIRED IN
SUCH A CASE. .,.�� \Illllllll /llii...
