About this file
These are design and planning drawings for a U.S. Army Corps of Engineers maintenance dredging project on the Delaware River between Philadelphia and Trenton. The project involves dredging approximately 470,000 cubic yards of sediment from the main navigation channel and Fairless Turning Basin, with hydraulic cutterhead dredging to a depth of 41 feet Mean Lower Low Water (MLLW) plus 1 foot overdepth. Dredged materials will be placed in the Money Island Disposal Area in Falls Township, Pennsylvania.
The documents include detailed technical specifications, site maps, and general notes about the dredging project. Key technical details include coordinate references (NAD 83, New Jersey State Plane), survey information from October 2024 to February 2025, and specific instructions for discharge pipe routing and material placement. The project has environmental restrictions requiring completion by March 15, 2026, with a total performance period of 240 calendar days from the Notice to Proceed. The estimated project value is between $10-25 million, using NAICS code 237990 for Heavy and Civil Engineering Construction.

GENERAL NOTES:
1. THE EXISTING SITE CONDITION SURVEYS ARE A RESULT OF SURVEYS CONDUCTED IN OCTOBER 2024 (LEHIGH TO FLORENCE), MAY 2024 (FLORENCE TO NEWBOLD), FEBRUARY 2025 (FAIRLESS TURNING BASIN) AND DECEMBER 2024 (BLAKE TO DUCK ISLAND), AND CAN ONLY BE CONSIDERED REPRESENTATIVE OF THE CONDITIONS OCCURRING AT
THAT TIME.
2. HORIZONTAL REFERENCE - NAD 83, NEW JERSEY STATE PLANE, ZONE 2900, US SURVEY FEET.
3. SOUNDINGS ARE EXPRESSED IN FEET AND TENTHS AND REFER TO MEAN LOWER LOW WATER (MLLW). SEE DETAILS
ON THIS SHEET FOR THE TIDAL REFERENCE FROM NOAA'S TIDAL EPOCH - 1983-2001.
4. CHANNEL SOUNDINGS WERE SELECTED FOR PLOTTING PURPOSES ONLY USING THE MINIMUM DEPTH WITHIN A 50'x50' CELL AND SHIFTED TO THE CELL'S CENTER. FAIRLESS TURNING BASIN SOUNDINGS WERE SELECTED FOR PLOTTING PURPOSES ONLY USING THE MINIMUM DEPTH WITHIN A 30'x30' CELL AND SHIFTED TO THE CELL'S CENTER.
HYPACK MATRIX PROGRAM WAS USED TO PERFORM THE SOUNDING SELECTION.
5. DUE TO VARIATIONS IN RESOLUTION BETWEEN COLOR BANDS AND CONTOURS, SOME MINOR DISCREPANCIES MAY BE NOTED. COLOR BANDS ARE FOR PLOTTING PURPOSES ONLY. COLOR BANDS WERE GENERATED USING THE MINIMUM DEPTH WITHIN A 3'X3' CELL, AND SHIFTING TO THE CELL'S CENTER. HYPACK MATRIX PROGRAM WAS USED
TO PERFORM THE SOUNDING SELECTION.
6. THIS SURVEY MEETS STANDARDS AS OUTLINED IN CORPS OF ENGINEERS HYDROGRAPHIC SURVEY MANUAL
EM1110-2-1003, FOR NAVIGATION AND DREDGING SUPPORT SURVEYS.
7. QUESTIONS CONCERNING BOTH HORIZONTAL AND VERTICAL CONTROL SHOULD BE DIRECTED TO PHILADELPHIA DISTRICT CORPS OF ENGINEERS SURVEY BRANCH POC, STEPHEN FARRELL, AT (215) 656-6790.
8. THE POSITIONS OF THE AIDS TO NAVIGATION ARE PROVIDED FOR INFORMATION ONLY, AND SHOULD NOT BE USED
FOR NAVIGATION.
9. FOR CHANNEL CENTERLINE GEOMETRY, SEE THE CONTRACT SPECIFICATIONS.
10. THE CONTRACTOR MUST COORDINATE WITH ALL APPROPRIATE UTILITY COMPANIES AND THE USACE RESIDENT OFFICE FOR MARK-OUT OF ONSITE UTILITIES PRIOR TO BEGINNING CONSTRUCTION ACTIVITIES.
11. SEE SPECIFICATIONS FOR DATUM CONVERSION INFORMATION.
GENERAL NOTES - DREDGED MATERIAL PLACEMENT FACILITY:
1. THE GOVERNMENT FURNISHED DREDGED MATERIAL PLACEMENT FACILITY (DMPF) AVAILABLE FOR USE
UNDER THIS CONTRACT IS MONEY ISLAND CELL B. SEE SHEET C-401 FOR DMPF PLANS.
2. THE END OF ALL DISCHARGE PIPES SHALL BE LOCATED INSIDE THE DISPOSAL AREA LIMITS AS SPECIFIED IN THE CONTRACT SPECIFICATIONS. PIPE SHALL BE LOCATED SUCH THAT THE DISCHARGE DOES NOT SCOUR THE SLOPE FACE OR THE TOE-OF-SLOPE OF THE DISPOSAL AREA DIKE IN THE VICINITY OF THE
DISCHARGE AREA.
3. BORROW FOR DIKING MATERIAL MAY BE OBTAINED FROM WITHIN THE DISPOSAL AREAS, BUT NOT CLOSER
THAN 50 FEET FROM THE INSIDE TOE OF THE DIKE SECTIONS.
4. SHOULD THE CONTRACTOR DESIRE TO MODIFY THE DISCHARGE LIMITS SHOWN, APPROVAL MUST BE
GRANTED BY THE CONTRACTING OFFICER PRIOR TO MODIFICATION.
5. TOPOGRAPHY SHOWN FOR MONEY ISLAND DMPF ARAES A & B WAS DEVELOPED BY EMPLOYING AERIAL ACQUISITION AND GPS COLLECTED CONTROL POINTS COMPLETED ON 4/4/2025. CONTOURS (2 FOOT INTERVAL) AND SPOT ELEVATIONS SHOWN CAN ONLY BE CONSIDERED REPRESENTATIVE OF THE SITE CONDITIONS AS THEY EXISTED AT THE DATES INDICATED. EARTHWORK ACTIVITIES HAVE TAKEN PLACE SINCE THE TOPOGRAPHY WAS GENERATED. CONTRACTORS ARE STRONGLY ENCOURAGED TO VISIT THE SITE WHERE WORK IS TO BE PERFORMED TO ACQUAINT THEMSELVES WITH EXISTING CONDITIONS THAT
COULD AFFECT THE PROJECT COST.
6. TOPOGRAPHY SHOWN OUTSIDE OF THE DMPF WAS GENERATED USING PHOTOGRAMMETRIC METHODS
BASED ON AERIAL PHOTOGRAPHY DATED DECEMBER 19, 2018.THIS MAPPING WAS COMPILED IN
ACCORDANCE WITH THE NATIONAL STANDARD FOR SPATIAL DATA ACCURACY (NSSDA) ACCURACY
STANDARDS FOR MAPS AT 1 INCH EQUALS 200 FT. SCALE.
7. THE SITE IS GENERALLY CLEAR WITH PASSABLE ACCESS ROADS, BUT SOME MINOR CLEARING OF
VEGETATION MAY BE REQUIRED IN ISOLATED LOCATIONS TO GAIN ACCESS.
8. HORIZONTAL REFERENCE - NAD 83, NEW JERSEY STATE PLANE, ZONE 2900, US SURVEY FEET.
9. VERTICAL REFERENCE FOR THE DMPF IS NAVD88 (GEOID 18) IN U.S. SURVEY FEET.
10. VERTICAL REFERENCE OUTSIDE OF THE DMPF IS MSL WHICH IS 0.48 FT ABOVE NAVD88.
