PRIOR TO THE START OF ANY GRADING.

THE CONTRACTOR SHALL CLEAR ALL PHRAGMITES,

VEGETATION, SHRUBS, AND TREES FROM WITHIN THE

CONTRACTOR SHALL VERIFY THAT BLENDED SOIL

MEETS THE REQUIREMENTS OF SUITABLE MATERIAL

EVERY 1,000 CY OR FRACTION THEREOF PRIOR TO

PLACEMENT.

SUITABLE FILL MATERIAL SHALL BE PROPERLY

BENCHED INTO EXISTING SLOPES. REFER TO BENCHING

DETAIL SHEET 12.

MATERIAL LOCATED WITHIN THE PLACEMENT SITE IS

DREDGED MATERIAL AND WAS PLACED

HYDRAULICALLY. CONTRACTOR SHALL ASSUME THAT

THE MATERIAL IS VERY LOOSE/SOFT AND WILL REQUIRE

CONSTRUCTION EQUIPMENT WITH LOW GROUND

PRESSURE TO FACILITATE WORK.

IT IS RECOMMENDED THAT ALL DIKE SLOPES BE

MONITORED FOR SIGNS OF SHALLOW SLOUGHING,

PRIMARILY WITHIN THE LOWER PORTION OF THE SLOPE.

MONITORING SHALL BE DONE BY A GEOTECHNICAL

ENGINEER WITH EXPERIENCE IN SPOTTING POTENTIAL

SLOPE INSTABILITY.

SEE SECTION 31 00 00 EARTHWORK FOR DETAILS.

ESTIMATED CUT/FILL VOLUME TO CONSTRUCT DIKE:

CUT: 1,900cy FILL: 49,700cy.

MAINTAIN A SLOPE AS SPECIFIED IN CROSS-SECTIONS

ON SHEET 9. IF CLEARING AND GRUBBING CAUSES A

STEEPER SLOPE THEN IT MUST BE FIXED BY THE ADDITION

AND COMPACTION OF MATERIAL TO THE REQUIRED

SLOPE WITHIN 48 HOURS.

REFER TO SHEET 3 FOR LAYDOWN AREA.

PROVIDE INLET PROTECTION AT SPILLBOX AND PIPES

AROUND THE FACILITY. REFER TO DETAIL F ON SHEET 10.

MINIMUM FILL OVER OUTLET PIPE AT SPILLBOX 2.0'.

CONTRACTOR SHALL FOLLOW EM 385-1-1 "SAFETY AND HEALTH

REQUIREMENTS" FOR EXCAVATION AND TRENCH SLOPES DURING

REMOVAL AND INSTALLATION OF OUTFALL PIPES.

DISCHARGE PIPING FOR THE NEW SPILLBOX SHALL BE INSTALLED

USING 24 INCH BITUMINOUS COATED CORRUGATED METAL PIPE (CMP),

SIMILAR OR EQUAL TO EXISTING CMP TO BE DEMOLISHED.

UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL

EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED

AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND

SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL

HANDBOOK (3RD EDITION, 1992).

THE CONTRACTOR SHALL APPLY PERMANENT OR TEMPORARY SOIL

STABILIZATION TO ALL DENUDED OR DISTURBED AREAS WITHIN 7 DAYS

AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. SOIL

STABILIZATION MUST ALSO BE APPLIED TO DENUDED OR DISTURBED

AREAS WHICH MAY NOT BE AT FINAL GRADE BUT WHICH WILL REMAIN

UNDISTURBED FOR LONGER THAN 14 DAYS. SOIL STABILIZATION MEASURES

INCLUDE VEGETATIVE ESTABLISHMENT, MULCHING AND THE EARLY

APPLICATION OF GRAVEL BASE MATERIAL ON AREAS TO BE PAVED.

THE CONTRACTOR SHALL INSPECT ALL EROSION CONTROL MEASURES

PERIODICALLY AND AFTER EACH RUNOFF PRODUCING RAINFALL EVENT.

ANY NECESSARY REPAIRS TO MAINTAIN THE EFFECTIVENESS OF THE

EROSION CONTROL DEVICES AND CLEANUP OF SEDIMENT ARE THE

RESPONSIBILITY OF THE CONTRACTOR AND SHALL BE MADE IMMEDIATELY.

STOCK PILES OF SOIL AND OTHER ERODIBLE MATERIALS SHALL BE

STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES. THE

CONTRACTOR IS RESPONSIBLE FOR THE TEMPORARY PROTECTION AND

PERMANENT STABILIZATION STOCKPILES ON SITE AS WELL AS FOR

MATERIALS TRANSPORTED FROM THE PROJECT SITE.

EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR

PASSED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH,

AS REQUIRED BY THE CONTRACTING OFFICER’S REPRESENTATIVE AND

DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT

OFF-SITE PROPERTY OR STORM DRAINAGE SYSTEMS.

THE CONTRACTOR IS RESPONSIBLE FOR INSTALLATION AND MAINTENANCE

OF ANY ADDITIONAL CONTROL MEASURES NECESSARY TO PREVENT EROSION

AND SEDIMENTATION AS DETERMINED NECESSARY BY THE CONTRACTING

OFFICER’S REPRESENTATIVE.

TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES ARE NOT TO BE

REMOVED UNTIL ALL DISTURBED AREAS ARE STABILIZED. AFTER STABILIZATION

IS COMPLETE, ALL MEASURES SHALL BE REMOVED WITHIN 30 DAYS.

TRAPPED SEDIMENT SHALL BE SPREAD AND SEEDED.

ALL DISTURBED AREAS SHALL DRAIN TO APPROVED SEDIMENT CONTROL

MEASURES AT ALL TIMES DURING LAND DISTURBING ACTIVITIES AND DURING

SITE DEVELOPMENT UNTIL FINAL STABILIZATION IS ACHIEVED.

ALL EROSION AND SEDIMENT CONTROL MEASURES INDICATED ON THIS PLAN

ARE THE MINIMUM REQUIRED. THE CONTRACTOR IS RESPONSIBLE FOR THE

INSTALLATION OF ANY ADDITIONAL EROSION CONTROL MEASURES NECESSARY

TO PREVENT EROSION AND SEDIMENTATION AS DETERMINED BY THE

CONTRACTING OFFICER’S REPRESENTATIVE.

ALL SEDIMENT BARRIERS AND OTHER MEASURES INTENDED TO TRAP

SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY

LAND-DISTURBING ACTIVITY, AND SHALL BE MADE FUNCTIONAL PRIOR TO

UPLAND LAND DISTURBANCE.

TEMPORARY CONSTRUCTION ENTRANCES SHALL BE MAINTAINED TO MINIMIZE

THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO PAVED

SURFACES. WHERE SEDIMENT IS TRACKED ONTO PAVED SURFACES, THE

SEDIMENT SHALL BE REMOVED BY SHOVELING OR SWEEPING AND

TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA.

CONTRACTOR SHALL MONITOR AND TAKE PRECAUTIONS TO CONTROL DUST

INCLUDING (BUT NOT LIMITED TO) USE OF WATER, LIMITING THE NUMBER OF

VEHICLES ALLOWED ON SITE, MINIMIZING THE OPERATING SPEED OF ALL

VEHICLES, OR PROVIDING OTHER ACCEPTABLE CONTROL MEASURES.

PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED UNTIL

A GROUND COVER IS ACHIEVED, THAT IN THE OPINION OF THE CONTRACTING

OFFICER, IS UNIFORM AND MATURE ENOUGH TO SURVIVE, AND WILL INHIBIT

EROSION.

GENERAL NOTES

REFER TO SPECIFICATION SECTION 31 00 00 FOR

EARTHWORK AND COMPACTION REQUIREMENTS.

NO DISTURBED TURF AREAS SHALL REMAIN BARE

SOIL FOR MORE THAN 14 DAYS.

INVERTS OF THE DRAINAGE PIPE RUNNING UNDER

THE LANDFILL ROAD SHALL BE MAINTAINED AND

INLET/OUTLET SHALL BE KEPT FREE FROM

SEDIMENT AND DEBRIS.

1.3 Geotechnical Data

While it is believed that the borings depicted accurately indicate subsurface conditions for boring locations on the date taken, the Government assumes no responsibility for actual conditions which may be encountered in the execution of the contract. Should the Contractor rely, for any purpose, upon the accuracy or completeness of said borings, or log thereof, they do so at their own risk. The geotechnical data included in the plans and specifications are for information only.
