1. MULTI-BEAM SOUNDINGS WERE SELECTED FOR PLOTTING PUPOSES ONLY, USING THE AVERAGE DEPTH WITHIN A 3'X3'

CELL, AND SHIFTED TO THE CELL'S CENTER. COASTAL OCEANOGRAPHIC'S HYPACK MATRIX PROGRAM WAS USED TO

PERFORM THE SOUNDING SELECTION.

2. THIS SURVEY MEETS STANDARDS AS OUTLINED IN CORPS OF ENGINEERS HYDROGRAPHIC SURVEY MANUAL EM

1110-2-1003, DATED 30NOV13 FOR NAVIGATION AND DREDGING SUPPORT SURVEYS.

3. HORIZONTAL DATUM REFERENCE FOR A.S. #1 IS NAD 83, DELAWARE STATE PLANE, ZONE 0700, U.S.FOOT.

SEE SHEET C-001 FOR VERTICAL DATUM REFERENCES.

4. THE INFORMATION DEPICTED ON THIS MAP REPRESENT THE RESULTS OF SURVEYS MADE ON THE DATES INDICATED

AND CAN ONLY BE CONSIDERED AS INDICATING THE GENERAL CONDITIONS EXISTING AT THAT TIME.

7. CONTRACTOR SHALL ENSURE THAT THE DISCHARGE END OF THE DREDGE PIPE EXTENDS A MINIMUM OF 50 FEET PAST THE INTERIOR

TOE OF THE CONTAINMENT DIKE AND IS SUPPORTED IN ACCORDANCE WITH THE CONTRACT SPECIFICATIONS.

8. REEDY POINT SOUTH DISPOSAL AREA WAS USED AS A BORROW PIT SINCE THE LATEST SURVEY DATE SPECIFIED. IT IS THE

CONTRACTORS RESPONSIBILITY TO VISIT THE SITE AND FAMILIARIZE HIMSELF WITH THE CURRENT CONDITIONS THAT COULD AFFECT

PROJECT COST.

9. BORROW FOR DIKING MATERIAL MAY BE OBTAINED FROM WITHIN THE DISPOSAL AREAS, BUT NOT CLOSER THAN 50 FEET PAST THE

INTERIOR TOE OF THE CONTAINMENT DIKE.

10. THE LOCATIONS OF THE EXISTING INSTRUMENTATION (I.E., MONITORING WELLS, ETC.) PROVIDED ON THIS SHEET ARE

PEARCE CREEK DISPOSAL AREA NOTES:

1. FOR LEGEND AND GENERAL NOTES, SEE SHEET C-001.

2. THE TOP OF THE EXISTING PERIMETER DIKE SERVES AS AN ACCESS ROAD TO THE DISPOSAL FACILITY. THERE IS A 6" LAYER OF CR-6 CRUSHER RUN AGGREGATE ALONG THE TOP OF THE

PERIMETER DIKE AND IT SHALL BE RESTORED TO ITS ORIGINAL CONDITION AT NO ADDITIONAL COST TO THE GOVERNMENT IF DAMAGED.

3. AT NO TIME SHALL THE CONTRACTOR BE PERMITTED TO ENTER INTO OR RUN EQUIPMENT INTO THE MINIMALLY COVERED LINER AREA (THE HATCHED AREA SHOWN). IF THE LINER IS

DAMAGED IN ANY WAY, IT SHALL BE REPAIRED AT NO ADDITIONAL COST TO THE GOVERNMENT. THE COVERED LINER AREA MAY BE DRIVEN OVER ONLY WITH LOW GROUND PRESSURE

EQUIPMENT OR VEHICLES HAVING TIRE/TRACK PRESSURES LESS THAN 5 PSI AND AS APPROVED BY THE COR.

4. PIPES ABANDONED IN PLACE HAVE BEEN FILLED WITH CONCRETE AND COVERED WITH 3FT ± OF SOIL AND LINER WITHIN THE PERIMETER DIKE. THE CONTRACTOR SHALL TAKE ALL

NECESSARY PRECAUTIONS TO AVOID DAMAGE TO THE GROUTED PIPES.

5. ALL EXISTING FACILITIES, INCLUDING BUT NOT LIMITED TO THE FOLLOWING, SHALL BE PROTECTED AGAINST DAMAGE: WELLS, BOLLARDS, GAS VENTS, SLUICE PAD, OUTLET PIPES, RIPRAP

BASIN, LINER (COVERED AND UNCOVERED) AND SETTLEMENT PLATES. DAMAGE CAUSED TO ANY EXISTING FACILITIES SHALL BE REPAIRED AT NO ADDITIONAL COST TO THE GOVERNMENT.

6. THE LIMITS OF FILL OVER LINER WERE SURVEYED ON 1 MARCH 2017. THE DMCF HAS BEEN UTILIZED SINCE THAT TIME AND ACTUAL CONDITIONS MAY VARY FROM THOSE SHOWN.

7. SCOUR APRON IS COMPRISED OF 40 MIL LINEAR LOW DENSITY POLYETHYLENE (LLDPE) PLACED OVER THE EXISTING SOIL.

8. ENSURE THAT THE DREDGE DISCHARGE PIPE(S) IS PLACED AT THE DISCHARGE LOCATION(S) SHOWN. THE LENGTH OF PIPE INSIDE THE DISPOSAL AREA SHALL BE SUFFICIENTLY AND SAFELY

SUPPORTED ALONG THE ENTIRE LENGTH BY TIMBER CRIBBING, AN EARTHEN EMBANKMENT, PIPE BARRELS OR OTHER MEANS APPROVED BY THE COR. DISCHARGE PIPE SUPPORTS ARE NOT

PERMITTED TO PENETRATE THE EXISTING GROUND SURFACE IN ANY WAY. SEE SPECIFICATIONS FOR FURTHER DETAILS ON SUPPORTING DISCHARGE PIPE.

9. DISCHARGE PIPE SHALL BE POSITIONED INSIDE THE DISPOSAL AREA IN SUCH A MANNER THAT ALL DISCHARGE MATERIAL SHALL LAND IN THE CENTER OF THE LLDPE DISCHARGE SCOUR

APRON.

10. IN ORDER TO PREVENT SCOUR AND/OR DAMAGE TO THE LINER SYSTEM WITHIN THE PEARCE CREEK DISPOSAL AREA FACILITY, WELD OR OTHERWISE SECURELY ATTACH A STEEL PLATE OR

OTHER COMPATIBLE MATERIAL TO THE END OF THE PROVIDED DISCHARGE PIPE TO ACT AS A DIFFUSER/DEFLECTOR. THE ANGLE OF THE DIFFUSER/DEFLECTOR PLATE SHALL BE

APPROXIMATELY 45 DEGREES, UNLESS OTHERWISE APPROVED BY THE COR. THE DIFFUSER/DEFLECTOR PLATE WILL ENSURE THAT THE DREDGED MATERIAL SLURRY DOES NOT DROP

DIRECTLY ONTO THE GROUND AND/OR LINER BELOW THE END OF THE DISCHARGE PIPE. IT WILL ALSO FUNCTION TO CHANGE THE DISCHARGE ANGLE FROM HORIZONTAL, REDUCE SLURRY

MOMENTUM, AND DISPERSE THE SLURRY FROM CONCENTRATED PIPE FLOW TO A FAN-LINK SPRAY.

11. SHOULD THE CONTRACTOR DESIRE TO MODIFY THE DISCHARGE LINE ACCESS LIMITS SHOWN, APPROVAL MUST BE GRANTED BY THE CONTRACTING OFFICER PRIOR TO MODIFICATION OF THE

LIMITS.

12. THE END OF ALL DISCHARGE PIPES SHALL BE LOCATED INSIDE THE DISPOSAL AREA LIMITS AS STATED IN THE SPECIFICATIONS. PIPE SHALL BE LOCATED SUCH THAT THE DISCHARGE DOES

NOT SCOUR THE SLOPE FACE OR THE TOE OF SLOPE IN THE VICINITY OF THE DISCHARGE AREA.

13. EXISTING DIKES SHALL NOT BE EXCAVATED OR DISTURBED IN ANY WAY, UNLESS OTHERWISE APPROVED BY THE COR.

15. SINCE THE DISPOSAL AREA WAS MODIFIED AND LINED WITH A LLDPE GEOMEMBRANE IN 2016 - 2017, NO DIKE MODIFICATIONS WILL BE REQUIRED TO PREPARE THE AREA TO ACCEPT DREDGED

MATERIAL. ANY REQUIRED FILL FOR DIKING MATERIAL, PIPE SUPPORT, ACCESS RAMPS, ETC. SHALL BE OBTAINED ONLY FROM APPROVED OFFSITE SOURCES.

16. THE LOCATIONS OF THE EXISTING INSTRUMENTATION (I.E. INCLINOMETERS, WELLS, PIEZOMETERS, ETC.) ARE APPROXIMATE. FIELD LOCATE INSTRUMENTATION SHOWN USING THE

COORDINATES PROVIDED IN THE TABLE SHOWN ON SHEET C-402. IF CONTRACTOR IS UNABLE TO LOCATE THE EXISTING INSTRUMENTATION, THE COR SHALL BE NOTIFIED PRIOR TO

BEGINNING WORK IN THAT AREA. DO NOT DISTURB EXISTING INSTRUMENTATION. REPAIR AND/OR REPLACE INSTRUMENTATION AT NO ADDITIONAL COST TO THE GOVERNMENT.

17. EXISTING SITE FEATURES SHOWN OUTSIDE THE PERIMETER DIKE ARE BASED ON LIDAR DATA FROM APRIL 2014. DISPOSAL AREA FLOOR ELEVATIONS ARE BASED ON AS-BUILT SURVEYS BY

MCCRONE SURVEYORS SHOT BETWEEN JANUARY 2016 AND FEBRUARY 2017. TOPOGRAPHY SHOWN CAN ONLY BE CONSIDERED INDICATIVE OF THE SITE CONDITIONS AS THEY EXISTED AT

THE TIME OF EACH SURVEY. THE DMCF HAS BEEN UTILIZED SINCE THESE SURVEYS AND ACTUAL CONDITIONS MAY VARY FROM THOSE SHOWN. IT IS THE CONTRACTORS RESPONSIBILITY TO

VISIT THE SITES AND FAMILIARIZE HIMSELF WITH CURRENT CONDITIONS THAT COULD AFFECT THE PROJECT COST.

18. CONTROL: PROVIDED BY THE US ARMY CORPS OF ENGINEERS, PHILADELPHIA DISTRICT. COORDINATES SHOWN ARE EXPRESSED IN US SURVEY FEET AND REFERENCED TO THE NORTH

AMERICAN DATUM OF 1983 (NAD) - MARYLAND STATE PLANE. ELEVATIONS SHOWN ARE EXPRESSED IN FEET AND ARE REFERENCED TO THE NORTH AMERICAN VERTICAL DATUM OF 1988

(NAVD88).

19. FOR ROAD CROSSING DETAIL, SEE SHEET 2/C-401.
