NOTES:

1. ELEVATIONS ARE IN FEET AND REFER TO NOAA'S REPORTED MEAN LOWER LOW WATER (MLLW )

RELATIVE TO THE 1983-2001 TIDAL EPOCH.

2. DATE OF IMAGERY: JANUARY 2021.

3. DATE OF SURVEY: APRIL 26, 2021 AND JUNE 16 AND 30, 2021.

4. PROJECT SURVEYED WITH DISTRICT SURVEY VESSEL "POTTER" AND "ROGERS", USING

RTK-G.P.S. HORIZONTAL POSITIONING EQUIPMENT AND 200 KHZ SOUNDING EQUIPMENT.

5. ALL COORDINATES ARE BASED ON NORTH CAROLINA STATE PLANE FEET (NAD83).

VERTICAL DATUM BASED ON MLLW, FEET.

6. TIDE GAGE FOR SHALLOTTE INLET SURVEY LOCATED AT: LIGHT 83.

7. THE DREDGING SHALL BE ACCOMPLISHED SO THAT THE MOST SUITABLE MATERIAL AVAILABLE FOR

BEACH RENOURISHMENT IS PLACED WITHIN THE PRESCRIBED SECTION. THIS MATERIAL SHOULD BE

PREDOMINATELY OF SAND (SP, SP-SM) GRAIN SIZE WITH NO MORE THAN 10% BY WEIGHT PASSING THE

NO. 200 SIEVE. SHOULD THE MATERIAL BEING PLACED ON THE BEACH CONTAIN AN AMOUNT OF SILT AND

CLAY THAT EXCEEDS THE 10% BY WEIGHT PASSING THE NO. 200 SEIVE AND CONSIDERED NOT SUITABLE

FOR PLACEMENT ON THE BEACH , THE CONTRACTOR SHALL MOVE THE DREDGE TO A MORE SUITABLE

LOCATION WITHIN THE BORROW AREA AND NOTIFY THE CONTRACTING OFFICER OF THE LOCATION OF

THE UNSUITABLE MATERIAL WITHIN THE BORROW AREA.

8. CONTRACTORS DREDGING SHALLOTTE INLET AND THE AIWW IN THE PAST HAVE ENCOUNTERED ROCK

AND/OR HARD MATERIAL WITHIN THE HATCHED AREA AS SHOWN AND AT ELEVATIONS ABOVE THE BORROW AREA

EXCAVATION LIMITS (-15' MLW) AS SHOWN ON THE PLANS. THE APPROXIMATE LOCATION OF THIS ROCK AND/OR

HARD MATERIAL IS WITHIN THE HATCHED AREA AND BETWEEN THE EAST END OF OCEAN ISLE BEACH AND THE

BORROW AREA DREDGING LIMITS AND WITHIN THE AREA BETWEEN THE BORROW AREA DREDGING LIMITS AND

THE ADJACENT AIWW CHANNEL LIMITS.
