A new beach improvement and shoreline stabilization project to manage Waikiki Beach erosion is complete. The effort between the DLNR Office of Conservation and Coastal Lands (OCCL) and the Waikīkī Beach Special Improvement District demonstrates a successful public-private partnership with the district funding half of the project cost and providing logistical and technical support through the University of Hawai‘i Sea Grant Program.
The project consists of a 95-foot-long sandbag stub groin and the transfer of approximately 1000 cubic yards of beach sand from the Diamond Head swim basin of Kuhio Beach. The groin and beach sand serve to stabilize the Diamond Head (Southeast) end of Kuhio Beach park fronting the Duke Kahanamoku statue. The work is intended to fix an erosion hot spot in the far eastern corner of Royal Hawaiian Beach until a more comprehensive master planning effort for Waikīkī Beach can be completed.
The project was completed after three weeks of construction. Sea Engineering provided the coastal engineering and permitting services for the construction.
