However, the beaches are still of ample size and I think as a whole the town fared much better than the town directly to the south (where there has been no recent replenishment). Again, to answer the question is difficult because who is to say that the storm erosion wasn't just stronger in the town to the south then it was in Harvey Cedars? It very well could have been. However, as far as the jetties and groins go, it has been shown that they do work to increase erosional rates compared to no jetty at all. At any rate, I would be first to complain that the replenishment destroyed some great breaks two years ago. However, I am much more thankful for the fact that we still have a beach to go to and the ocean side block was not destroyed. So IMO, can sand stop mother nature....of course not, but can it slow erosion, protect property, and portend beaches of adequate size....I think in one town it did.
