sections of fence collected very little sand due to the influence of existing 

 dunes, which appeared to alter the wind patterns. 



The planted beachgrass plots had a 95- to 98-percent mortality. The fabric 

 fence collected sand initially but later failed structurally. The fence section 

 with side spurs was destroyed due to the inlet shifting to the north during a 

 coastal storm in November 1969. The CERC project was relocated to the Nauset 

 Harbor south spit (Fig. A-3) in April 1970.
