Final Report Bogue Banks Beach & Nearshore Mapping Program Periodic Survey Evaluation A target minimum volume for each profile from the foredune (landward most crest of the primary dune) to the outer bar (above -12 ft NAVD88) was established at 225 cy/ft during the formulation of the Bogue Banks Beach Restoration Project. Along Bogue Banks and Bear Island, the average profile volume from the dune to the outer bar exceeds the 225 cy/ft threshold. The average profile volume on Shackleford Banks is currently below the 225 cy/ft threshold. Figure 9 displays the average profile volume to the outer bar per transect within each reach of shoreline for 2008 - 2011. Values displayed in the graph are tabulated in Table 14.
