RReelleevvaanntt PPrroojjeeccttss Project Title: North Shore Flood Protection, O‘ahu, Hawai‘i Client: City & County of Honolulu, Department of Environmental Services Statement of Qualifications {Insert Category} As part of the “community vision” sponsored by the City and County of Honolulu, the Ko‘olau Loa community on O‘ahu identified flood control as one of their key issues. However, before flood control alternatives are implemented, the community requested that an environmental baseline be determined for the nearshore environment to help monitor and minimize negative impacts on the environment. GIS data layers for Kahuku were used to obtain a snapshot of existing environmental conditions. Water quality monitoring sites were geocoded to enable the analysis and mapping of trends in the data. A password-protected project web site was created for the client and community to learn about the project, obtain data about the project, and provide input on the project via an online bulletin board. Water quality, bathymetry, currents, benthic biological surveys, waves, beach profiles, and sediment characteristics were monitored by Oceanit. Water quality sampling including the use of in situ sensor technology to monitor and post data on a project web site. Java programming was used to create an interactive interface that enabled the user to view and compare different water quality parameters over time and space. Oceanit also provided the client and community with a multimedia CD-ROM including full motion video and photographs of the project site, report methods, data, and report results. Oceanit was in close contact with the community and was involved in organizing marine debris cleanup efforts. Oceanit preformed environmental baseline monitoring, water quality, bathymetry, currents, benthic surveys, waves, beach profile, sediment, characteristics. Water quality sampling including the use of in-situ sensor technology to monitor and post real-time data on a client password protected extranet site. Water collected from different drainages during a storm shows markedly different sediment loads.




Project Title: Water Quality Monitoring for Marine Life Conservation District Ko Olina Client: West Beach Estates, Oahu Ko Ol ina Resort Development involved construction of a marina and several man-made lagoons for recreation. Oceanit developed an ocean and nearshore water quality monitoring program for the project that included baseline water quality monitoring and monitoring water quality during and after construction. The project involved dredging the backshore area to construct the marina and the lagoons. Water quality in the marina, lagoons, Barbers Point Deep Draft Harbor, and offshore was monitored on a periodic basis to evaluate potential impacts from the development and also to determine the effectiveness of flushing of lagoons by tidal and wave induced circulation. Results showed minimal water quality impacts and sufficient circulation in lagoons to maintain water quality pa ramete rs w i th in accep tab le va lues . At the request of the client, Oceanit developed a plan for the creation of a Marine Life Conservation District (MLCD) in the ocean off of the resort properties. The plan included a review of physical and biological resources of the ocean off of Ko`Olina as well as management strategies that would be required to protect these resources, impacts to the surrounding community, and safety concerns. Based upon the results of the study the developer determined that this location was not appropriate for the establishment of a MLCD.



Project Title: Investigation & Conceptual Remedial Design Fuel Pipeline Leak, Victor-1 Dock, Fleet & Industrial Supply Center, Pearl City Peninsula, O‘ahu, Hawai‘i

Client: EarthTech/U.S. Navy


Rupture of a jet fuel line in Pearl Harbor contaminated the soil around the damage and the water close to the Victor-1 Dock. Oceanit was hired to design remediation for the contaminated area under the Comprehensive Long-Term Environmental Action Navy II (CLEAN II) contract. Oceanit developed a work plan, obtained approvals for the client from the Department of Health, conducted topographic surveys, conducted ground penetration radar surveys to identify subsurface pipes and facilities; obtained subsurface samples; and analyzed the samples to determine the degree and the area of the contamination. Oceanit constructed monitoring wells and monitored groundwater samples to determine water contamination. Oceanit achieved the project objectives: 1. Delineate the horizontal and vertical extent of JP-8 contamination in soil and groundwater as a result of the pipeline leak. 2. Develop a conceptual remedial design for the contaminant cleanup based on the results of the site investigation. Oceanit performed all field investigations, laboratory analyses, disposal of investigation-derived waste (IDW), conceptual remedial design, report preparation, and environmental engineering services. As the principal consultant under EarthTech to the U.S. Navy, Oceanit coordinated the effort with the Navy and EarthTech, prepared health and safety plans, and work plans. Oceanit provided environmental engineering services and supervised or performed all field investigations, construction, sampling of monitoring wells, analysis of water and soil samples, removal of IDWs, delineation of subsurface contaminated areas, and development of conceptual remedial designs. Oceanit coordinated with the Department of Health and assisted in the preparation of closure reports. Project reports prepared in accordance with CERCLA were delivered to the Navy Contractor (EarthTech) and accepted as final.



Project Title: Waikele Total Maximum Daily Load, Waikele, O‘ahu, Hawai‘i

Client: State of Hawaii, Department of Health (DOH), Environmental Planning Office

Statement of Qualifications {Insert Category}This study established “Order of Magnitude” Total Maximum Daily Loads (TMDLs) and load reduction allocations for three pollutants found in freshwater portions of the Waikele stream system—total suspended solids (TSS), total nitrogen (TN), and total phosphorous (TP). The TMDL study was commissioned by the State of Hawaii DOH with guidance and funding from the U.S. Environmental Protection Agency (EPA) under Section 303(d) of the Clean Water Act (CWA). Past studies have shown that Waikele stream delivers large loads of sediments and nutrients to the West Loch of the Pearl Harbor estuary. The State’s CWA Section 303(d) list identifies Waikele as impaired by excessive turbidity and nutrients. The 50 square mile watershed was divided into subbasins and an automated water sample collection regime was established. In situ data from meters and data from collected samples was used to calibrate hydraulic, sediment load, and nutrient load models. The results of the model analyses indicated that the bulk of sediment yield due to large storms was generated from conservation areas above areas of human impact. Ninety percent of Nitrogen entered the stream, probably through springs, near the base of the stream far below most human impacted areas.




Project Title: Maintenance Dredging of Paukauila Stream Mouth, O‘ahu, Hawai‘i Client: State of Hawaii, Department of Land and Natural Resources Oceanit was contracted to provide engineering plans and specifications, prepare an environmental assessment (EA), and obtain permits required to dredge a portion of Paukauila Stream in an effort to mitigate flooding problems in the area. A field survey was performed in order to determine riverbed level contours, with results presented in a bathymetric map of the project area. Dredged quantities were calculated and specified in drawings. Contract documents consisting of construction plans, specifications, and other relevant information were prepared. A benthic habitat survey was conducted to develop a biological baseline. Potential dredged material disposal sites and acceptable disposal methods were identified and specified. Sediment and water samples were collected to determine baseline conditions at the site before dredging activities began. Results from these samples along with other physical impacts of the dredging were evaluated in the EA. All permits required for the dredging were identified and obtained for the client. Permits included a Department of Army Permit, Department of Health Water Quality Certification, Coastal Zone Management Consistency Permit, Conservation District Use Application Permit, Stream Alteration Permit, and NPDES Permit.



Project Title: Kaneohe Total Maximum Daily Load, Kaneohe, O‘ahu, Hawai‘i Client: State of Hawaii, Department of Health (DOH), Environmental Planning Office


This total maximum daily load (TMDL) study was commissioned by the State of Hawaii DOH under guidance from the EPA and Section 303 of the Clean Water Act to better understand the loadings of pollutants to the Kaneohe Stream system and to assist in developing mechanisms to control the pollutant load to below acceptable State Standards. The State’s Section 303(d) list identified the Kaneohe Stream as impaired due to elevated turbidity, suspended solids, and nutrients. Past studies have shown that this stream has very high sediment and nutrient loadings as it enters Kaneohe Bay. Key sources of these pollutants were thought to arise from agricultural uses near the slopes of the Koolau Mountains and intense urban development of Kaneohe Town. While loading from golf course and agriculture operations near the foothills should remain a concern, there is no direct evidence linking these activities to pollutant loads. The main bulk of the nitrogen loading

occurs in the mid to lower watershed and may emanate from groundwater during periods of low base flow. During periods of storm runoff sediment and nutrient levels in the stream exceed state standards throughout the watershed. The 6½ square mile watershed was divided into five subbasins based upon drainage. Sampling stations were located to characterize water quality from each basin and at specific points within certain basins. Water flow was determined using the HEC hydraulic model. Loading estimates for total nitrogen, total phosphorous, and total suspended solids for each subbasin were calculated for baseflow (non-rain, non-runoff) wet season, baseflow dry season, and for storm flow conditions.




Project Title: Technical, Environmental and Economical Feasibility Studies for Kahului Harbor Landfill Expansion, Kahului, Maui, Hawai‘i Client: State of Hawaii, Department of Transportation (DOT), Harbors Division The Harbors Division of the State DOT is responsible for the operation and maintenance of commercial harbors in the State of Hawai‘i. Kahului Harbor is located in Kahului, Maui, and handles about 90 percent of export from and import to the island. Recent expansion of economy combined with the increasing use of the harbor by passenger cruise vessels created a shortage of safe space for containers and general cargo handling. One of the recommended options for harbor expansion was to construct a landfill on the ocean side of the existing harbor breakwater to the north of the harbor. Oceanit investigated and analyzed the technical, environmental, economic, and regulatory feasibility of constructing the landfill. Oceanit conducted field investigations, environmental analysis, and economic and regulatory research to compile the feasibility report. Oceanit completed the following 17 tasks. 1) Established horizontal and vertical control points for hydrographic surveys. 2) Conducted a bathymetric survey outside the east breakwater. 3) Conducted current measurements in the vicinity of the proposed landfill. 4) Determined the physical, chemical, and biological water quality status in the nearshore area. 5) Conducted a benthic survey to evaluate the benthic environment. 6) Determined design wave parameters from existing wave data. 7) Determined grain size characteristics of beach and bottom material. 8) Estimated sea level rise during the lifetime of the construction. 9) Calculated 50-year hurricane storm surge conditions. 10) Determined 50-year tsunami flooding conditions. 11) Designed the optimum height and size of the landfill. 12) Designed a retaining wall for the landfill. 13) Developed preliminary cost estimates. 14) Analyzed environmental data and determined environmental impacts of the landfill construction. 15) Conducted economic analysis and compared the costs of alternatives. 16) Identified necessary regulatory permits. 17) Prepared the feasibility report.



Project Title: Engineering and Design of Kalaeloa Desalination Plant, Reverse Osmosis Facility Client: City and County of Honolulu, Board of Water Supply (BWS)


O‘ahu obtains most of the drinking water from deep groundwater resources. Over the years, the groundwater has been depleted resulting in a drop of the water table. In order to avoid unsustainable levels of groundwater resource and the potential risk of aquifer contamination from agricultural chemicals, the BWS plans to develop independent sources of drinking water. Oceanit was selected as the prime consultant to provide engineering consulting services for the design of a 5 million gallon per day desalination plant to be constructed in Ewa, O‘ahu, Hawai‘i.

Project Title: Aliomanu Road Repair, Island of Kauai, Hawai‘i Client: Department of Public Works, County of Kauai Aliomanu Road leads into a subdivision on the shoreline of Anahola Bay on the windward coast of Kauai. The road has been undercut by waves and sections of the paved surface have collapsed leaving only one usable lane for traffic. Oceanit is providing plans and permits for road and embankment repair in a two-phased effort. The first phase is to place emergency shore protection consisting of gabions and large sandbags along the worst eroded section and to maintain an existing rock revetment along the remaining threatened section.


The road and shoreline have been surveyed and geotechnical borings made. Oceanit is preparing design plans and permits for the emergency repair. This will be followed by design and permits for a permanent reinforced concrete seawall with a rock toe as a long-term solution. After shore protection is installed, the road will be repaired. Permits for the long-term repair include a Corps of Engineers Permit, a 401 Water Quality Certification, a CZM federal consistency determination, a state Conservation District Use Permit, a County SMA Use Permit, a Shoreline Setback Variance, and an Environmental Assessment. Project Title: Coastal Engineering Studies for Brennecke Beach Coastal Revetments,

Island of Kaua‘i, Hawai‘i Client: Department of Public Works, County of Kaua‘i Brennecke Beach suffered severe beach erosion from Hurricane Iniki. Coastal engineering field measurements & studies were performed, including offshore bathymetric measurements, water quality sampling & analysis, sand grain size and distribution analysis, and current/wave studies. Oceanit performed coastal planning and engineering studies to design a protection scheme for Hoone Road in preparation for the removal of a seawall, located at the project site. An environmental assessment (EA) was performed (including a marine benthic assessment), submission of permit applications to federal, state, and county regulatory agencies. As part of the environmental assessment, this project was presented to the community for their input at community meetings, and public hearings.




Project Title: Repair of Wave Protection Structure at Honolulu International Airport Client: State of Hawaii, Department of Transportation (DOT), Airports Division

The reef runway breakwater protects the main runway of the Honolulu International Airport from erosion. The wave protection structure was constructed in 1975 and was inspected and repaired when damage occurred. Waves from Hurricane Iniki caused settlement, armor damage, and sloughing of the seaward face of the structure. State DOT contracted Oceanit to inspect the structure, assess damage, design repairs, decide on repair priority, and prepare plans and specifications for the length armored with dolos units. Oceanit inspected the structure both above and below water; conducted level surveys to assess settlement; measured the slope to assess the degree of sloughing, armor damage, armor roll off, and single and cluster damage on the outward

face; and prepared a damage assessment report. Using the damage assessment report, Oceanit developed a weighting scheme for different damage criteria. These damage criteria were applied to 100-foot sections of the structure. Oceanit calculated the damage index on a 1-to-10 scale. Repair priorities were established based on the combined damage index. Oceanit prepared designs, cost estimates, plans, and specifications for damage repair and projected the damage locations on an aerial photograph made for this purpose. Oceanit assisted DOT in bid evaluations, contractor selection, and conducted inspection services during repair.




Project Title: Shoreline Access Inventory, Maui, Hawai‘i Client: County of Maui Maui County contracted Oceanit to complete a revision to their 1986 Shoreline Access Update. Many laws and the actual access points in the County have changed substantially. Priority sites were established for each Community Plan through field research, interviews, conversations with community members and groups, and a review of federal, state, and county shoreline access documents. After priority access areas were established for each Community Plan, each site was evaluated against the s p e c i f i c a s s e s s m e n t c r i t e r i a .

Maui, Moloka‘i, and Lana‘i were surveyed, During the survey, tracking from a GPS unit was used to identify the latitude/longitude, Tax Map Key (TMK), and ownership of each site; this information was subsequently mapped into a GIS database and overlaid with the GIS data layers provided by the Maui County Planning D e p a r t m e n t . The inventory report established shoreline access priorities and review criteria, identified legislation affecting shoreline access, and recommended site acquisitions. GIS data, demographic maps, and TMK maps were used to identify trends and statistics in shoreline access. The inventory report can be used as a tool to reevaluate and reprioritize access points on a regular basis.




Project Title: Honolulu Harbor Piers 17–38 Bulkhead Survey, Phase 1, O‘ahu, Hawai‘i Client: Honolulu Harbor Working Group

Piers and docking areas throughout the Honolulu Harbor area have been constructed, renovated, and repaired over the past century by numerous contractors using a variety of construction methods, not all of which have been adequately documented. In addition, pipelines have been installed, removed, and abandoned in a haphazard fashion throughout decades of use by multiple parties. Pollutants (primarily petroleum hydrocarbons) from numerous sources are known to be present in soils behind the bulkhead and leaching into harbor waters. The State of Hawaii Department of Health has required harbor tenants and users to address leaks of pollutants into harbor waters. Oceanit was hired by the Honolulu Harbor Working Group (HHWG), a consortium of stakeholders to the pollution problem, to inspect, identify, and categorize specific breaches in the structural integrity of over two miles of pier bulkhead (between Piers 17 and 38). Surveys were conducted from land and at and below water level under the piers. Active and potential contamination release points were identified along the bulkhead and under-pier piping. Findings were prioritized and presented to the HHWG in a report and a GIS database hyperlinked to digital photos and video.




Project Title: Mauna Lahilahi Beach Park, Waianae, Hawai‘i Client: Department of Design and Construction, City and County of Honolulu Oceanit previously developed plans for a temporary sandbag revetment to protect Makaha Surfside Apartments on the leeward side of Oahu. Located just landward of the eroding shoreline, it was damaged by hurricanes and by seasonal high waves on several occasions. Oceanit, under contract to the City and County of Honolulu, designed a temporary sandbag revetment to protect inland areas, a breakwater to reduce wave energy, and a restored beach. The breakwater and beach were constructed in mid-2003. The breakwater is a rubble structure extending about 250 feet parallel to the eroding shoreline. The beach w a s b u i l t w i t h 1 0 , 0 0 0 c u b i c y a r d s o f s a n d f r o m a n i n l a n d q u a r r y .

Oceanit is responsible for designing a permanent structural solution to the ongoing problem. Tasks include: bathymetric surveys, characteristics of wave and current conditions to optimize design, and plans and specifications for a shore protection structure. Oceanit is also responsible for benthic su rveys , env i ronmenta l assessmen ts , and a l l pe rm i ts requ i red fo r the p ro jec t .

Project Title: Pier 15 Honolulu Harbor Bulkhead Inspection Client: Mitsunaga and Associates Pier 15 consisted of two sections, one approximately 150 feet long where the fireboat Moku Ahi was berthed and another approximately 430 feet long where fishing boats were berthed. Above water and underwater inspections were made of the existing bulkhead at Pier 15. The objective of the inspection was to determine the condition of the bulkhead, identify damaged areas, and determine the as-built configuration so that the fire pier could be repaired or rebuilt.

The inspection revealed that the fire pier had been repaired several times in recent years. These repairs included pilings, timber structures, and voids in the bulkhead. The inspection also showed that the fishing pier had been repaired or modified multiple times. The pier deck has been condemned because pilings were missing and wood components were severely damaged.



Project Title: Ma'alaea Harbor Survey Client: Corps of Engineers for State of Hawaii Department of Land and Natural Resources


Ma`alaea Harbor on the south-west coast of Maui services recreational boating and a thriving small commercial fleet focused on serving the visitor industry. The harbor was initially constructed in 1952 and received various physical improvements up through 1979. In 1989 funds were allocated to design an expansion to the harbor to meet increased boating demand and address surge problems in the existing harbor. An EIS, SEIS, and second SEIS were published in 1990, 1994, and 1998. Plans for the existing harbor and harbor improvements were found not to be up to present-day CADD or MicroStation standards and biological marine habitat data from adjacent waters could not be fixed relative to the proposed improvement structures.

Oceanit was contracted to provide: • Topographic survey of the site surface structures, sub-

surface utilities, marine bathymetry, and nearshore significant coral habitats.

• Verify previous marine biological habitat locations to updated survey

• Verify currents internal to the harbor • Review erosion on adjacent beaches • Review coral damage from adjacent moorings outside the

harbor. This update was designed to bring all existing physical information on the harbor into a unified computer database compliant with USACE computer graphic standards for MicroStation autocadd.

Project Title: Marine Environmental Assessment for the Aloha Tower Redevelopment Honolulu Harbor, O‘ahu, Hawai‘i Client: Aloha Tower Associates The Aloha Tower Redevelopment project was a major part of Hawaii’s waterfront development plan. Construction work included dredging, reclamation, and construction of maritime and mooring facilities as well as high-rises. Oceanit assessed the impact caused to the marine environment and prepared an environmental assessment document suitable for attachment to the required environmental impact statement (EIS). Investigations of the entire nearshore marine environment included environmental concerns regarding dewatering discharge from construction, thermal plumes, hazardous and toxic materials disposal, recreational fishing, etc. General environment of the site and the surrounding area, and the physical conditions of the environment were documented. These conditions, including waves, tide, currents, bathymetry and topography, sediments, general climate, storm exposure, tsunami and storm flooding were evaluated for possible impacts due to the changes in the harbor. Oceanit then assessed the impact of construction activities on the water quality of Honolulu Harbor and potential impacts on marine life in the harbor. Adverse impacts, mitigation, alternatives and reports were then prepared.




Project Title: Remote Anthropogenic Sensing Project (RASP) Client: United States Navy

Sand Island Wastewater Treatment Plant discharges 75 million gallons of treated wastewater each day into Mamala Bay through a submerged outfall located two miles off shore and 230 feet deep. The wastewater plume dilutes by mixing with ambient seawater and reaches an equilibrium depth depending on water stratification. The path of the plume is important from public health as well as ecological points of view. The Remote Anthropogenic Sensing Program was developed to track the path of the submerged wastewater plume by using remote data collected by satellites. The study team consisted of Oceanit, Isintech from Russia, Directed Technologies from Washington D.C., Scripps Oceanographic Institute, and NAVAIR. The project was funded by NAVAIR and Oceanit was contracted to plan and conduct all field investigations and provide logistical support to the other members of the study team. Oceanit deployed moored recording instruments to continuously measure current profiles and temperature profiles during the investigation period. Imagery from the Ikonos satellite was obtained for the study area. During the 10 minute transit of the satellite, Oceanit had 10 boats deployed in the area conducting salinity, temperature, water quality, plankton, wave, current and wind measurements. Oceanit monitored the flow volume and quality of the effluent from the treatment plant to check dilution levels in the ocean. Data from Ikonos was divided into a one-kilometer square grid, and the intensity of sun glint was analyzed using special Fourier Transforms. The analyzed signals showed anomalies caused by the internal waves generated by plume turbulence. Results were used to plot the path of the plume that extended several kilometers from the outfall.




Project Title: Kualoa Regional Park Erosion Control Design Department Parks and Recreations Client: City and County of Honolulu, Department of Parks and Recreation Kualoa Regional Park shoreline has been undergoing progressive erosion for the past few decades. The north east shorelines erode at an average rate of 3 feet per year and Kualoa Point recedes at a rate of 7 feet per year. Numerous erosion control structures were tried at the park shoreline, but did not solve the erosion problem. Oceanit was contracted by the City and County of Honolulu to develop a comprehensive scheme to abate erosion of the shoreline. Oceanit conducted hydrographic investigations and evaluated several potential solutions for erosion control. Oceanit designed and constructed a physical hydraulic model of the complete park and the shoreline at 1 to 100 scale to test the effectiveness of different solutions under different wind, wave and current conditions. Oceanit calibrated the model and operated it for one year to test various erosion control structure configurations and developed a solution for the erosion problem. Oceanit prepared plans and specifications for construction of the structures and an Environmental Impact Statement for the project. Oceanit also obtained the required Federal, State and County permits for construction. Project Title: Beach erosion, Dune Certification, Palauea Beach, Maui, Hawai‘i Client: Private Beachfront Property Owners Owners of shoreline property around Palauea Beach on Maui were faced with new Maui County shoreline setback rules that would have severely restricted buildable area on coastal lots. The Maui County Planning Department used erosion rates determined by the University of Hawai‘i (UH) to determine shoreline setbacks for coastal building sites. Oceanit evaluated the methods and results of the UH study then made an independent study of erosion rates at Palauea to assist landowners in planning for home design and development. Oceanit collected historical aerial photographs of Palauea Beach from various sources. Each photograph was rectified using photogrammetric methods to make the photograph dimensionally correct. A registered surveyor established ground control points at Palauea Beach using the UTM Zone 4 (meters) projection referred to the WGS 84 datum. The position of the beach toe was then visually estimated and traced on the rectified historical photo. All of the traced beach toe lines were overlaid and displayed using a GIS program. The UH transects were also overlaid, and Oceanit used these transects for a direct comparison with the UH results. Erosion rates were calculated by measuring the distance from a baseline to the crossing points of beach toe lines on each transect. Oceanit was successful in determining more accurate erosion rates, which ultimately benefited our client.



Project Title: Environmental Assessment for Construction of Ocean Wastewater Outfalls Client: Environet/U.S. Army Corps of Engineers

Statement of Qualifications {Insert Category}Oceanit was contracted by the US Army Corps of Engineers to prepare and Environmental Assessment for construction of wastewater treatment plant, collection systems, and ocean outfalls for Kagman and Tinian in Commonwealth of Northern Mariana Islands. Oceanit subcontracted consultants for plant design, collection systems design, flora, fauna, and archaeological assessments. Oceanit conducted the ocean outfall studies and evaluated impact of wastewater discharge on water column, benthic habitat, and coral reefs around the discharge area. Oceanit installed recording current meters and temperature profilers at the proposed discharged sites, analyzed data to determine the dilution and dispersion characteristics of the wastefield, and assessed the impacts of the wastewater on water quality, benthic flora and fauna, coral reefs and the public health impact on the adjacent beaches. Project Title: Saipan Lagoon Aquatic Ecosystem Restoration Project Client: Environet/U.S. Army Corps of Engineers Oceanit provided biological assessment support to evaluate restoration alternatives for the Saipan Lagoon and coastline habitats. This habitat was impacted by runoff from increasing coastal development, coastal structures, and possibly other factors. This study identified information gaps that needed to be addressed before any physical remediation projects could be adopted. Project Title: Kaho‘olawe Small Boat Harbor, Kaho‘olawe, Hawai‘i Client: U.S. Army Corps of Engineers

(COE), Honolulu District The U.S. Navy used the island of Kaho‘olawe for arms testing for several years. As a condition of handing over the island to the Kaho‘olawe Island Reserve Commission (KIRC), the Navy cleared unexploded ordnance from some areas of the island. The State of Hawai‘i was responsible for continuation of ordnance cleanup after November 2004. The island does not have a harbor for boats to carry goods and personnel for clearing work. Using helicopters as was done by the Navy is very expensive and would severely slow down ordnance clearing. The KIRC would like to construct a small craft harbor at Kaho‘olawe to allow goods and personnel to be transported by boat. The COE contracted Oceanit to prepare a feasibility report for the harbor construction. Oceanit evaluated five promising sites. Oceanit conducted underwater inspections to observe ecological conditions at these sites to assess the potential impacts of harbor construction. Oceanit evaluated existing wave, current, and wind data; the archaeological significance of the sites; and potential ordnance hazards and selected the optimum site for the harbor. Oceanit developed a harbor layout and prepared cost estimates for harbor construction and maintenance. The feasibility report included cost-benefit analysis.
