Another study

From a 2004 publication on coastal erosion - it does point at that the breakwaters are Holley beach would be a good solution.

Sargent Beach (Fig. 20) is a good example of accelerated erosion. Since the mid-1800s, Sargent Beach has retreated almost 700 m at an average rate of -4.4 ± 2.2 m/yr. That rate has increased to -6.4 m/yr since the 1970s. Here the beach is steep, narrow, and composed of many clam and oyster shells that normally grow in the bays but not in the open Gulf. The absence of dunes and presence of a low overwash terrace that forms the backbeach are clear indicators of the rapid erosion and frequent storm waves that are responsible for the rapid land loss. Sargent Beach is far from sand sources and engineering projects and yet there is an unmistakable connection between updrift activities and the accelerated erosion. In 1929, the mouth of the Brazos River was relocated so that the entrance to Freeport Harbor would not shoal when the river flooded. After the river diversion, a delta formed at the river mouth and trapped the sand that normally would have flowed toward Sargent Beach.
