and September. Shortly after these surveys were completed, Category 2 Hurricane Isabel
hit the area on September 19. Post-hurricane surveys were immediately conducted at four
of these six sites, and the data sets were included in the database. Analysis of these data
sets indicates the breakwaters provided significant protection to land in the lee of the
breakwaters and that the structures experienced little or no damaged. Additionally, the
sand introduced to the sediment budget as a result of the storm cutting into the banks of
adjacent unprotected properties may have enhanced the breakwater systems by accelerat-
ing the equilibrium beach building process. Other types of structures and in the area and
the shores they protected sustained much greater damage than the sites in this study.
Surveys were conducted in the August and September of 2004 on six different sites and
information has been analyzed and entered into the database. A draft technical report of
the impacts of Hurricane Isabel is in review.
