FILTER FABRIC TO BE PLACED UNDER RIP RAP FROM TOE OF SLOPE TO TIE
POINT WITH BERM.
CUMULATIVE AVERAGE OF RIP RAP PLACED BELOW THE MEAN HIGH WATER
LINE WILL BE 0.48 CUBIC YARDS per RUNNING FOOT.
MHWL = MEAN HIGH WATER LINE
PROJECT SURVEYED BY NCDOT LOCATION AND SURVEYS PERSONNEL.
LOCATION OF EXISTING RIP -RAP WAS PARTIALLY LOCATED IN FIELD,
2016 IMAGERY WAS USED TO SUPPLEMENT LOCATION.
