Avalon - The Army Corps of Engineers will get paid to replace seawalls by someone. They put extensions at right angles to the flow of the water. This causes a backwash and deep water. Any non-engineer can see this. They ruined Avalon Inlet by trying to make water go straight, and now the north end of Avalon has to be replenished constantly. They basically create never ending work for themselves. Also, enriching the friendly quarry owner.
