2021 Waikīkī Beach Improvement and Maintenance Program
The State Department of Land and Natural Resources is proposing beach improvement and maintenance projects for the Fort DeRussy, Halekūlani , Royal Hawaiian, and Kūhiō Beach sectors of Waikīkī. The project will include the construction of new beach stabilization structures, the recovery of off-shore sand, and its placement on the shoreline. The objectives of the proposed actions are to restore and improve Waikīkī’s public beaches, to increase beach stability through the improvement and maintenance of shoreline structures, and to increase resilience to coastal hazards and sea level rise.
The draft Environmental Impact Statement (dEIS) for the program was published on June 8, 2021.
A public scoping meeting on the EISPN was held on Thursday, January 7.
The presentation is available to download.
2021 Waikīkī Beach Maintenance Project
Immediately following nourishment in May 2021 the beach had been widened by an average of 29.7 feet, and there was an area increase of approximately 52,000 square feet of dry beach. Subsequent surveys shows a reduction in overall beach width in the fall and winter, and an increase in the spring. Sand in this area also shifts seasonally, as is the case on many Hawaiian beaches. The western end tends to gain more in the summer months, while the eastern end decreases. In the winter the distribution is reversed.
Surveys in April 2022, one year after the completion of the project, showed that the dry beach had been widened by an average of 37.1 feet, with an area increase of approximately 65,000 square feet of dry beach.

2021 Waikīkī Beach Maintenance Project
The Waikīkī Beach Special Improvement District Association (WBSIDA). in close partnership with the Department of Land and Natural Resources (DLNR), conducted a beach maintenance project for the Royal Hawaiian to Surfrider Moana beach area. The goal of the Waikiki Beach Maintenance Phase II project was 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 project started on January 26, and stockpiled 20,000 cubic yards of offshore sand, retrieved from shallow water about 1000-feet offshore. The project was completed in May 2021.
Waikīkī Beach Restoration
Since 1985 the Waikīkī shoreline has experienced significant beach loss due to long-term chronic erosion. The State has recognized that given the chronic erosion potential simply importing sand is not a permanent solution. There is a need to develop a program for regular beach maintenance using nearshore sand as a means for periodic beach nourishment. This “recycling” program offers a more efficient method for maintaining a recreational beach while mitigating some of the environmental effects of imported sand to the Waikīkī ecosystem over the past sixty-plus years.
