Figure 5.25: View northeastward onto Chincoteague Bay and toward Assateague Island from Franklin City, Virginia. Previous efforts to help stabilize the shoreline through the use of riprap and old building materials (a very common practice used historically) were in vain. Hurricane Sandy, combined with the impacts of Hurricane Irene two years earlier, resulted in erosion and retreat of the shoreline. In some places, as much as 14’ of erosion occurred along this length of shoreline. Where the shoreline was piled up with oyster shells, the erosion rate was significantly lower at around 4’ compared to riprap areas. So, although the erosion still took place, oyster-protected shorelines are usually subject to less erosion.
