Waikiki Beach Maintenance Project

(COMPLETED MAY 7, 2021)

The Waikīkī Beach Special Improvement District Association (WBSIDA) is working in close partnership with the Department of Land and Natural Resources (DLNR) for a beach maintenance project for the Royal Hawaiian to Surfrider Moana beach area.  The goal of the Waikiki Beach Maintenance Phase II project is to restore and maintain the public beach between the Kuhio Beach Ewa Groin and the Royal Hawaiian Groin.  The project includes hydraulic dredging and pumping up to 20,000 cubic yards of marine sand from offshore Waikīkī as a follow up to the 2012 project which brought in 24,000 cubic yards to Waikīkī Beach.  The seaward limit of the restored beach will not exceed the historical position of the beach/water interface.  The WBSIDA is working closely with the DLNR to secure a confirmed start date.
