Two new islands were created nearby. The largest of the new islands, Akau Island, has an area of 24 acres and the other, Hikina Island, has 17.3 acres. About 16,000,000 cubic yards of material was deposited; of this total, approximately 463, 300 cubic yards provide coral stockpiles on Johnston and Akau Island. (Completed in 1964) Sheet piling was driven to form bulkheads for shoreline protection and docking facilities as follows: a. Johnston Island A new wharf (Bulkhead 2) is located at the west end of the island. The wharf is formed by steel piling enclosing a coral backfill and provides about 180 feet of mooring space fronting on a 15-foot deep channel area. b. AkaulIsland A wharf (Bulkhead 3) is constructed of steel piling to pro- vide about 350 feet of frontage. The area behind the piling is back- filled with coral and equipped with mooring fixtures. c. Hikina Island A wharf (Bulkhead 4) similar to the Akau Island facility is available. d. Sand Island. Two steel sheet pile bulkheads are located on the west of Island. Over 800 feet of shoreline is now lined by piling. In addition, a total of about 7,500 square yards of coral fill area was placed adjacent to the island causeway connecting the Baker-Nunn Camera Facility.
