Kīkīaola Small Boat Harbor

Kīkīaola Small Boat Harbor is located on the southwest coast of Kaua‘i about 23 miles from Līhu‘e. The harbor was constructed in 1959 by the State of Hawai‘i. Improvements were made to the harbor in 1961 and 1964.

Brennecke Beach

In September 1992, Hurricane Iniki caused severe erosion of Brenneck Beach on the island of Kaua'i. Despite beach nourishment efforts, the beach continued to erode, threatening to damage the coastal roadway and the low-lying land beyond the road. The presence of an old masonry seawall at the west end of the sandy beach was believed to be partially responsible for the slow recovery of the beach.

Waiehu Heights Well Hydrogeologic Study

The County of Maui, Department of Water Supply (DWS), needed to bring a specific well online by either replacing or repairing an existing well with excessively high salinity. Oceanit assisted DWS in deciding whether to repair or replace Well 1 in the Waiehu Heights battery. The report prepared by Oceanit discussed the feasibility of reducing the chloride levels in the well to acceptable levels using operational data, information from neighboring wells in the Iao Aquifer System, and general knowledge of the hydrogeology of the Iao Aquifer System.

Kahili Horizontal Directional Drilled Well

The Kauai Department of Water wished to reduce energy usage in its Lihue-Kapaa water system by drilling a horizontal gravity flow well to supply water. The location for the directionally drilled exploratory well was explored at the 800 to 1,200-foot elevation in the land divisions of Wailua, Hanamaulu, and Haiku. At this high elevation, the water can flow by gravity and has the potential to produce energy through the development of a hydroelectric plant.

Kolea and Wahikuli Dam Removal

In summary, Oceanit provided the State of Hawaii Department of Accounting and General Services (DAGS) and Department of Land and Natural Resources (DLNR) with engineering and environmental services for the removal of two state-owned dams on Maui.

Dam Break Analysis Program

In February 2006, the Hawaiian Islands experienced unusually severe rain showers that caused severe flooding throughout the State. The resulting heavy rainfall resulted in the failure of privately-owned Kaloko Dam on the Northeast side of the island of Kaua‘i. The dam failure sent a floodwave of water and debris downstream that overtopped the Morita Dam, damaged Kuhio Highway, and swept away homes resulting in 7 fatalities.

Kawainui Marsh Bird Habitat

Kawainui Marsh has played a highly significant role in Hawaii’s history and culture, and continues as a central focus of the surrounding community. The construction (1966) and enhancement (1990-92) of the Kawainui flood control levee by the USACD offered the opportunity to secure federal funds through the USACD Section 1135 for an ecosystem restoration project.

Maunalahilahi Beach Park

To improve damage caused by waves at Maunalahilahi Beach Park, Oceanit designed a temporary sandbag revetment to protect inland areas, a breakwater to reduce wave energy, and a restored beach.

Opaeula No. 2 (Oahu) Dam Decommission

Oceanit provided Kamehameha Schools with engineering consultation for construction improvements to three of its dams.
