About this file
These engineering drawings detail the U.S. Army Corps of Engineers' maintenance dredging project for the Lewes and Rehoboth Canal in Delaware. The comprehensive set of technical drawings (Sheets G-001 through C-402) provides specifics on the project's scope, including dredging approximately 90,000 cubic yards of sediment along a 37.3-mile canal stretch from Lewes to Rehoboth Bay, with dredging depths of -6 feet Mean Lower Low Water (MLLW) plus 1 foot allowable overdepth. The project includes two optional sections for additional dredging near Thompson Island and will utilize two dredged material placement facilities (Lewes Cell 1 and Lewes Cell 2) for material disposal.
The drawings include detailed plans showing the canal's precise geographic location, channel cross-sections at various stations, typical dredging sections, and comprehensive maps of the dredged material placement areas. The project allows for both hydraulic cutterhead and mechanical dredging methods, with a planned 365-calendar day completion timeline from the Notice to Proceed. The contract (Solicitation Number W912BU25BA001) is estimated between $10-25 million, with a projected bid date in April 2025 and a pre-bid site visit scheduled for Tuesday, April 8, 2025, at 400 Anglers Road in Lewes, Delaware.

GENERAL NOTES:
1. HORIZONTAL REFERENCE - NAD 83, DELAWARE STATE PLANE, ZONE 2900, US SURVEY FEET.
2. 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.
3. THE SOUNDING SURVEYS ARE A RESULT OF SURVEYS CONDUCTED IN FEBRUARY 2024, AND CAN ONLY BE
CONSIDERED REPRESENTATIVE OF THE CONDITIONS OCCURRING AT THAT TIME.
4. DUE TO VARIATIONS IN RESOLUTION BETWEEN COLOR BANDS AND CONTOURS, SOME MINOR DISCREPANCIES MAY BE NOTED. COLOR BANDS ARE FOR PLOTTING PURPOSES ONLY. SOUNDINGS USING THE AVERAGE DEPTH WITHIN A 3'X3' CELL, AND SHIFTING TO THE CELL'S CENTER. HYPACK MATRIX PROGRAM WAS USED TO PERFORM THE
SOUNDING SELECTION.
5. THIS SURVEY MEETS STANDARDS AS OUTLINED IN CORPS OF ENGINEERS HYDROGRAPHIC SURVEY MANUAL
EM1110-2-1003, FOR NAVIGATION AND DREDGING SUPPORT SURVEYS.
9. FOR SURVEY CONTROL DESCRIPTIONS, SEE THE CONTRACT SPECIFICATIONS.
10. 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.
11. THE POSITIONS OF THE AIDS TO NAVIGATION ARE PROVIDED FOR INFORMATION ONLY, AND SHOULD NOT BE USED
FOR NAVIGATION.
12. FOR CHANNEL CENTERLINE GEOMETRY, SEE THE CONTRACT SPECIFICATIONS.
13. THE CONTRACTOR MUST COORDINATE WITH ALL APPROPRIATE UTILITY COMPANIES AND THE CITIES OF LEWES AND REHOBOTH BEACH AS WELL AS THE SUSSEX COUNTY ENGINEER FOR MARK-OUT OF ONSITE UTILITIES PRIOR TO
BEGINNING CONSTRUCTION ACTIVITIES.
14. THE GOVERNMENT FURNISHED DREDGED MATERIAL PLACEMENT FACILITIES (DMPF) AVAILABLE FOR USE UNDER THIS CONTRACT IS LEWES CELL 1 AND CELL 2. FOR DMPF PLANS, SEE SHEETS C-401 AND C-402.
15. FOR CONTRACTOR ACCESS AND STAGING AREAS, SEE SHEETS C-401 AND C-402.
