Kahului is located on the northern coast of the island of Maui and is the site of the only commercial port on the island. Four Corps projects at Kahului include the Kahului Deep Draft Harbor, the Kahului Light Draft Harbor and the Kahului Bay Mitigation project.
Kahului Deep Draft Harbor
Kahului Harbor is Maui's only commercial port and is located on the northern coast of the island. The harbor was originally constructed by the Kahului Railroad Company in the early 1900s. Over the years, Federal modifications and repairs were made to the two large breakwaters protecting the harbor from the large waves generated by winter storms in the North Pacific Ocean. The latest major rehabilitation of the breakwaters was completed in 1983. The harbor’s three commercial piers total over 3,019 linear feet. The Federal project consists of rubble mound breakwaters on the east and west sides of the harbor, approximately 2,766 and 2,315 feet in length, respectively; an entrance channel 600 feet wide between the breakwaters; and a harbor basin 2,050 feet wide, 2,400 feet long at 35 feet deep. The cost of this project was $13,971,441 (Federal: $13,941,241; non-Federal: $30,200). The local sponsor is the State of Hawaii, Department of Transportation.
Kahului Light Draft Harbor
The Kahului Light Draft Harbor is located on the island of Maui and was constructed in 2006 at a cost of $2,654,475. The project was authorized by the River and Harbor Act of 27 July 1916, 25 June 1919, 21 January 1927, and 14 July 1960. Project features include: a 130-foot-long rubble mound breakwater structure with a crest elevation of +9.0 feet above Mean Lower Low Water (MLLW); an entrance channel 1,030 feet long, 50 feet wide, and 9.5 feet deep; and a turning basin 100 feet long, 100 feet wide, and 8.5 feet deep. The local sponsor is the State of Hawaii, Department of Transportation.
Kahului Bay Mitigation
The Kahului Bay Mitigation Project is located in Kahului on the island of Maui and was completed in 1976 at a cost of $751,900. The project was authorized under the authority of Section 111 of the River and Harbor Act of 1968. The project consists of an 890-foot-long revetment (which included the rehabilitation of an existing 380-foot-long revetment, built by the State in 1964); a 280-foot-long west groin; a 100-foot-long offshore breakwater; a 100-foot-long seaward extension to an existing 200-foot-long east groin (also built by the State in 1964); and the beach replenishment of 6,550 cubic yards of sand. The local sponsors are the State of Hawaii and the County of Maui.
