The local sponsor is the State of Hawaii Department of Land and Natural Resources Division of Boating and Ocean Recreation. The project is in the operations and maintenance phase.
The project was completed in 1966 at a cost of $1.2 million and cost shared with the State of Hawaii. General navigation features consist of an entrance channel 740 feet long, 100 to 120 feet wide, and 12 feet deep; revetted mole 1,310 feet long; stub breakwater 80 feet long; and wave absorber 140 feet long. Non-Federal project features include 64 berths, 26 moorings, 2 loading docks, and 3 ramps.
Haleiwa Beach Park, the shoreline surrounding Haleiwa Small Boat Harbor, is used for many recreational activities such as surfing, and stand-up paddle boarding. Haleiwa Small Boat Harbor is also used to provide recreational activities such as sportfishing, sailing, and whale watching.
The U.S. Army Corps of Engineers is responsible for maintaining the project structures and project depths in the entrance channel and turning basin area. Maintenance dredging was last completed in 2010.
