150 km (94 miles) southeast of Honolulu. It is protected by an 843-m- 

 long (2,766-ft-long) east breakwater and a 706-m-long (2,315-ft-long) 

 west breakwater (Figure 5). The structures were originally constructed 

 with a single layer of keyed and fitted, 7,260-kg (8-ton) armor stone. The 

 breakwaters are rich in construction, repair, and rehabilitation history, and 

 are probably the most complex in the Corps.

The harbor complex originated in 1900 when a 122-m-long (400-ft- 

 long) east breakwater was constructed by the Kahului Railroad Company. 

 The first involvement of the Corps with the project came in 1913 when 

 the east breakwater was extended by 122 m (400 ft). The west breakwater 

 was constructed to 594 m (1,950 ft) in length in 1919, and the structures 

 were extended to their current lengths in 1931. The first major rehabilita- 

 tion was completed in 1956 on both breakwaters, and consisted of the in- 

 stallation of 29,940-kg (33-ton) tetrapods and a concrete cap. The 

 concrete armor units were placed on the heads of both breakwaters and ex- 

 tended 76 m (250 ft) shoreward along the sea-side face of the west break- 

 water trunk. In 1959, a large monolithic concrete cap and the placement 

 of 10,885-kg (12-ton) and larger armor stone were used to repair a breach 

 in the east breakwater.
