2 INCH DEPTH BY SCARIFYING WITH HEAVY RAKES, SPIKED TOOTH HARROW, CHISEL

PLOWS, OR SIMILAR IMPLEMENTS, OR OTHER SIMILAR METHOD. ROTOTILLERS SHALL BE

USED WHERE SOIL CONDITIONS AND LENGTH OF SLOPE PERMIT. ON SLOPES

2. OVERLAY STAGING AREA WITH 6" NCDOT NO. ABC

3. RESTORE AND SEED STAGING AREA AT THE END OF THE CONTRACT

WHEN IT IS NO LONGER NEEDED. SEE SPECIFICATIONS.

4. CONTRACTOR SHALL RESTRICT HIS INGRESS AND EGRESS TO THE

CONSTRUCTED ACCESS/HAUL ROAD UNLESS OTHERWISE APPROVED

BY THE CONTRACTING OFFICER.

5. AT THE POINT WHERE THE ACCESS/HAUL ROAD BEGINS THERE IS

6. THE CONTRACTOR WILL BE RESPONSIBLE FOR MAINTENANCE OF

ACCESS/HAUL ROAD DURING CONTRACT PERIOD. ACCESS/HAUL

ROAD UTILIZES EXISTING ROAD AND IS INTENDED TO PROVIDE ALL

WEATHER ACCESS. HOWEVER, TO AVOID SEDIMENTATION, THE ROAD

WILL BE TEMPORARILY CLOSED WHEN INUNDATED OR SOILS ARE

VERY WET.

7. AN OVER HEAD TRANSMISSION LINE WILL BE CONSTRUCTED

BEGINNING ON OR ABOUT 27 OCTOBER 2009 AND CONTINUING

THROUGH THE END OF JANUARY 2010. LOCATION SHOWN IS

APPROXIMATE.

8. THE AREA BELOW THE DAM IS SUBJECT TO FLOODING DUE TO

RELEASES PRECEEDING OR FOLLOWING RAINFALL EVENTS OCCURING

IN THE AREA OR IN AREAS UPSTREAM OF THE PROJECT. THE

CONTRACTOR SHALL TAKE ALL NECESSARY PRECAUTIONS TO

PROTECT ENVIRONMENT AND PROJECT WORK TO THE EXTENT

POSSIBLE DURING THE CONTRACT PERFORMANCE PERIOD WHEN

WEATHER FORCASTS PREDICT A RAINFALL EVENT TO OCCUR. IN ANY

EVENT, AREAS DAMAGED DUE TO RISING WATERS DURING THE

CONTRACT PERFORMANCE PERIOD SHALL BE REPAIRED AT NO COST
