At 7:00 PM on Wednesday, February 9th, 2022, Norfolk Dredging Company (NDC) commenced dredging
operations at Ocean Isle Beach, NC in association with the Town of Ocean Isle Beach's Terminal Groin project.
As is required by the Department of Army individual Permit #SAW-2011-101241, Special Condition #13, one (1)
sediment sample was collected by Coastal Protection Engineering of North Carolina, Inc. (CPE) representatives
each morning that sand was being placed onto the beach between Station 0+00 and Station 10+00. Between
February 10 and February 17, material was placed between Station 2+00 and 10+00. During that time, a total of
eight (8) samples were collected. Sediment samples were processed for sediment grain size, silt %, and calcium
carbonate %. Upon completion of the CSRM project, NDC will return to place material within the outstanding
portion of the terminal groin fillet (from the location of the groin at Station -1+66 to Station 2+00). CPE
representatives will resume collecting sediment samples within this remaining portion of the fillet at that time.
Sampling locations were dependent on the location of the active outfall pipe each morning. Station locations and
coordinates (latitude, longitude) for each sample are presented in Table 1. Sampling locations are also shown in
Figure 1. Mean grain size ranged from 0.27 to 0.45mm. Percent fines ranged from 0.57 to 1.04%. Percent calcium
carbonate content ranged from 4 to 7%. A summary of results (mean grain size, % fines, % calcium carbonate,
and Munsell colors) for each sample are presented in Table 2. Individual granularmetric reports and grain size
distribution curves/histograms for each sample are provided in Appendix 1 and Appendix 2, respectively.
