The Harbor section runs from Brant Point to Wauwinet, including Coatue, Monomoy, Pocomo and Wauwinet. It is the most densely populated area, with 50 private structures across 52 separate properties. Since the Harbor section was so densely populated, it had a variety of different types of structures including: sand fences, rock walls, wooden fences, beach grass, jute bags, beach nourishment, zigzag fence, (metal, wooden and concrete) bulkheads, windscreens, rock and wooden groins. These were all private structures with the only public erosion structure being the jetties located at the entrance to the harbor. Sixteen (32%) of the structures showed signs of visible accretion of sand, but 30 (60%) of the structures showed signs of erosion. Five (10%) structures showed signs of both erosion and accretion.
