    Addendum to the environmental impact assessment for Three Islands, B. Thulhaadhoo
    (2011-06) Miruza, Mohamed
    The report is an addendum to the “Environmental Impact Assessment Report, Three Islands – B. Thulhaadhoo” report. The need for an addendum occurred to investigate any environmental impacts that may occur as a result of the proposed harbour expansion at B. Thulhaadhoo. The report documents the finding of the study carried out. The original Environment Impact Assessment undertook extensive surveys and research to determine the impacts carried out within a large study area including the area for the proposed harbour extension. General information on the island is therefore not provided in this addendum and is referred to this document. Furthermore, where substantial information is provided in the initial EIA on site specific data relevant for the harbour expansion, such information is highlighted in this EIA without the need for further field investigations. The study finds that there are no significant environmental impacts caused due to the proposed harbour expansion. However, the report does highlight some of the additional impacts that may occur and related mitigation measures have been provided for these. The report provides a monitoring plan for the new development while also referring to the initial monitoring plan proposed in the original EIA for continuous investigation of the environment for a sustainable development.

    Environmental impact assessment report harbour reconstruction at Vaadhoo, Gaafu Dhaalu Atoll
    (2011-06) Land and Marine Environmental Resources Group
    1. This Environmental Impact Assessment (EIA) report is to fulfill the regulatory requirements under the Environmental Protection and Preservation Act of Maldives prior to the proposed harbor restoration at Vaadhoo in GDh Atoll. 2. Project proponent of the proposed harbor restoration project is Ministry of Housing and Environment. The project was bided as a design and contract project. The main design consulting company MTCC is assigned to carry out the design works, and LaMer Group Pvt Ltd is assigned the EIA Consultancy. 3. Vaadhoo is located in GDh atoll, 440km from Male’. It is just about 40km from Kaadedhoo Airport. Nearest inhabited island is Fares-Maathodaa (8km on the south western side). In terms of geographic coordinates, it is located at 00° 14' 45" N and 73° 16' 30" E. Nearest islands are Vashavarrehaa approximately 4.1km north east and Farukolhuhuttaa approximately 5.2km south west of Vaadhoo. 4. The proposed development project involves renovation and restoration of Vaadhoo harbor with approximately 82m addition to the existing length of the harbor. With this expansion the overall length of the harbor basin would be 244 meters. Under the proposed project, new quay wall (concrete sheet piles, L section) and breakwaters (armor rocks) will be constructed at the existing foot prints. The harbor basin will also undergo maintenance dredging to -3MSL (where necessary). The concept plan is formulated in light of the new third generation harbor concept which is focused at functionality of the harbor. In this regard harbor usage components such as passenger embarking/disembarking, loading unloading area, fish landing, water and fuel recharging and mooring area will be demarcated. 5. The existing harbor facility is located at the northern side of the island and is accessed by an entrance channel north of the harbor. The project boundaries are existing footprint of harbor and 82.95m east of harbor where the harbor will undergo expansion. Under the proposed project harbor expansion and maintenance dredging will be carried out at the basin and entrance area where necessary. The project boundaries are; harbor front, side breakwaters, entrance area and breakwaters on side on entrance channel. Under the proposed project maintenance dredging will be carried out at the basin and entrance area where necessary and this activity will generate sediment plumes west wards. Dredged material removed during the maintenance dredging works and harbor extension works will be reused for construction. 6. The harbor will have a total length of 226.19m of breakwater at the east and western side of the entrance channel. The breakwater will be constructed of armor stones and remains of existing breakwater as core. The side quay will have a total length of 136m of type 2 design quay wall, while the main quay will have a length of 244m. 7. Approximately 16000m3 of dredged material will be generated by the maintenance dredging works. This sand will be reused during construction stage, thereby avoiding the need for disposal. 8. The existing harbor footprint will be expanded to eastwards to 82.95m under the proposed project. The existing quay wall and breakwaters will be replaced with concrete quay wall and rubble mound breakwaters. The size of harbor basin after completion of the project will be 244m in length and 78m in width. The length of entrance channel is approximately 123m, while width is 30m. The depth of basin is at average -3.0MSL, areas where design depth is not met will be deepened to -3MSL. Depth of entrance channel will be -4MSL. 9. Existing environment was examined to identify significant environmental components that would be affected and to establish a baseline condition of the site. Available and relevant literature on environmental impacts associated with similar projects was evaluated to identify possible impacts. Oceanographic data and information on local hydrodynamics were qualitatively assessed to determine the current pattern around the island which was based on monsoonal wind patterns, wind generated waves, tidal flushing, geographic setting, the topography of the lagoon and shape of the shoreline. 10. The reef flat area in front of harbor was dominated by massive life forms of Porites and faviids. Numerous small table coral colonies were observed behind the reef flat area dominating the rocky back reef towards the lagoon. Further inwards the reef flat is predominantly covered by sea grass meadow. 11. Project is predominantly a restoration project, environmental impacts associated with the proposed project are considered minor. Significant environmental components that are likely to be affected include coral community and sea grass bed at harbor front and harbor expansion area. The most significant impact associated with the project would be impact on these habitats from sedimentation. Dredging and excavation often carry a heavy load of sediments increasing sediment load in the water column causing discoloration due to suspended sediments of the impact area for a prolonged period. Since the project is small in scale in addition to restoration in nature, the extent of sediment plum is expected to be small and limited to the harbor basin and vicinity. 12. Mitigation measures have been provided for impacts associated with the project related works that have been categorized as minor to moderate. Impact mitigation measures and monitoring is carried out to compare predicted and actual impacts occurring from project activities to determine the efficiency of the mitigation measures. It has to be noted that no EIA has been carried out for the development of the harbor and no environmental monitoring has been done since the completion of harbor in 1997, and extent of changes to habitats such as sea grass, coral reef and shoreline is not known. 13. Stakeholder consultations were carried out as part of the EIA process. It was strongly emphasized by the stakeholders that the location of Vaadhoo makes it a good transit point for many trade vessels and Safaris boats making the harbor is fairly crowded. In addition, during good fishing season the harbor is also used by fishing vessels from other atolls as well. Due to this reason the community feels strongly that the harbor needs to be expanded. Since resorts are opening near the island, additional usage of harbor is envisaged therefore burden on harbor will increase. Overall the IDC and harbor committee was in favor of the project and very little issues apart from extension of harbor were raised during the stakeholder meeting 14. With due consideration to main environmental components identified and the magnitude of impacts on these components from the proposed developments, the consultant concludes that the project components and designs are feasible and appropriate mitigation measures are given to correct and minimize unfavorable environmental consequences. Furthermore, the public and community consultation responses were in favor of the project due to the socio-economic benefits foreseen to the community from a functional harbor.

    Environmental impact assessment report : development of Transit Hotel and Marina Finolloss, Baa Atoll
    (2011-09) Land and Marine Environmental Resources Group
    Background The non-technical summary outlines the findings of the Environmental Impact Assessment of the proposed Transit Hotel and a Marina facility on the island of Finolhoss, Baa atoll. This hotel is developed as part of the airport development project in Dharavandhoo, Baa atoll. The Transit Hotel at Finolhoss will be operated by Coastline Hotels and Resorts under Coastline Group of Companies Pvt Ltd. Project Detail Finolhoss will be developed as a luxury hotel, accommodating 200 beds offering a unique and exclusive product. The project will involve construction of 17 land villas (duplex), 32 water villas, and a small marina catering for small to medium sized yachts (8-15m yachts). The water villas would be constructed at the lagoon area from the northwest point of the island, while the land villas are to be built on the northern side of the Island. The marina and support facilities would be constructed at the southern side of the island within the shallow lagoon. Environmental Component of the project As the project is set in a coral reef based island the proposed component of the project are very much related to the surrounding environmental components. These include, the terrestrial vegetation, marine environment which includes reef, near-shore lagoon and intertidal beach. Use of field data collected during the field visit to the site in October 2010 and available secondary data on the said environmental components has been used to assess and evaluate potential environmental impacts that are likely to arise from implementation of the proposed project activities especially in the context of the magnitude and duration of the project components. Key impacts, mitigation measures and alternatives Possible impacts arising from the resort development and operation works are categorized into reversible and permanent (irreversible) impacts. The impacts identified are also described according to their location, extent (magnitude) and characteristics. Reversible and irreversible impacts are further categorized into intensity of impacts (negligible, minor, moderate and major) for identifying best possible remedial (mitigation measures) actions to be taken. In any development project major direct impacts to the environment (either short term or long term) occur mainly during the construction phase. Potential direct or indirect impacts on the environment (on land and reef system) from the proposed works are limited to number of causes. These include: Construction debris blown away by wind or spillage during transportation on to the reef or lagoon (initially material will be unloaded using barge, but after completion of harbor dredging works, the harbor will be used for material unloading), Potential changes to the long shore transport and littoral regime of the island due to the coastal developments (beach creation, backfilling works and harbor deepening works), Possible impacts from excessive sedimentation on the reef by beach creation works and harbor deepening works, as these may alter the local hydrodynamic regime within the system resulting in siltation and increased water turbidity, Direct loss of habitat and disturbance to the lagoon bottom and reef flat area by harbor dredging and piling works at the water bungalow construction areas, Direct loss of habitat and disturbance to the lagoon bottom by footing clearance for piling works for the over water structures, Loss of vegetation due to clearing vegetation for creating space for new constructions, Groundwater contamination by digging trenches or dewatering for placing foundations of building and possible spillage of fuel or other hazardous chemicals. Operation of heavy machinery and construction related equipment will contribute to noise pollution. Noise pollution during the construction works will be mainly due to the operation of excavators, trucks and concrete machines. Air pollution due to the project will be mainly due to operation of heavy machinery like excavators, trucks, concrete machines, power generator, burning of waste and boat operations. Mitigation measures Mitigation measures are discussed for the construction and operational stages of the project. During the construction stage it is important to take measures to minimize generation of construction waste; impacts due to disposal of construction waste may cause significant degradation of terrestrial habitat or groundwater quality or reef health. Method of construction also has to be taken in to account for minimized impact. A construction method that has the least impact on terrestrial or marine environment has to be utilized. Waste generated during the construction phase will be sorted and reused as much as possible (construction debris for construction works as filling, timber for form work). All burnable items will be burnt, rest sorted and sent to local disposal site or Thilafushi (disposal at Thilafushi will be costly due to long distance transportation). Project management staff will be appointed for monitoring waste generation and management of the contractors working on the island. All waste generated at end of each working day will collected and sorted and then sent to the waste management building. All burnable waste (timber flakes, saw dust, paper, and packing material) will be incinerated. Reusable items such as gunny bags, saw dust (for making compost) will be reused as much as possible. Food waste generated at the temporary accommodation and kitchen area will be collected in waste collection bins. Separate bins will be placed for collection of metal tins/glass bottles and plastics. All burnable items will be incinerated; glass bottles crushed, metal tins compacted and sent to local disposal site or disposed at deep sea. During construction stage green waste will be generated from the vegetation clearance works. All major vegetation (large mature trees) removed will be replanted elsewhere to the greatest extent possible. Daily cleaning works will also generate green waste; these would be used for making compost at the nursery. Alternatives Considering the alternatives for the project in terms of location, type of economic activity to be carried out has been decided by the Ministry of Tourism, Arts and Culture. Apart from the type of economic activity and location other aspects that can have alternatives are; Construction method of over water structures Location of over water structures Sewage treatment method Feed water intake method, outfall and brine discharge pipes Beach creation and back filling work Harbor basin deepening method Conclusion Assessment of the project components and their associated impacts have been considered in the context of baseline environmental information collected at the project location as part of this EIA report. It has been the general finding that the project components will bring environmental alterations to the project site if the activities are implemented. Several projects of similar nature have been developed over the past several decades as part of the Maldives tourism industry. No serious environmental damage has been reported or documented due to implementation of these projects. With due consideration given to the fragility of the natural environment, this document has discussed and identified mitigation measures for the potential impacts to the natural environment. The economic benefits from the project are likely to beneficial to the national economy at large.

    EIA report for restoration of K. Kaashidhoo harbour under construction of harbours for Tsunami Victims Project
    (2010-11-07) Land and Marine Environmental Resources Group
    1. This Environmental Impact Assessment (EIA) report is to fulfill the regulatory requirements under the Environmental Protection and Preservation Act of Maldives prior to the proposed harbor restoration at Kaashidhoo in Kaafu Atoll. 2. Kaashidhoo harbor restoration project is part of the Construction of Harbors for Tsunami Victims Project. This restoration project involves repair of harbors at 10 islands. The project is funded by a joint loan taken from Islamic Development Bank (IDB), the Saudi Government and Organization of the Petroleum Exporting Countries (OPEC) by the government of Maldives. The design consultancy was awarded to Alhabshi Consultants Office, a Kuwaiti Company in association with Riyan Pvt Ltd (a Maldivian company). The Agreement for consultancy was signed on 6th November 2008 between the Government of Maldives and Alhabshi Consultant. 3. Project proponent of the proposed harbor restoration project is Ministry of Housing and Environment. The project was bided as a design and consultancy project. The main design consulting company Alhabhsi Consultants is assigned to carry out the design works, preparing tender documents, carrying out EIAs and construction phase supervision consultant. 4. The proposed development project involves renovation and restoration of Kaashidhoo harbor. During the December 2004 Indian Ocean Tsunami, Kaashidhoo harbor facility received extensive damages. These include damage to harbor quay walls and basin. Under the proposed project, new quay wall (concrete sheet piles, L section) and breakwaters (armor rocks) will be constructed. The harbor basin and entrance channel will also undergo maintenance dredging to -3MSL. Since the proposed project is only a restoration project, basin size will not be increased. The concept plan is formulated in light of the new third generation harbor concept which is focused at functionality of the harbor. In this regard harbor usage components such as passenger embarking/disembarking, loading unloading area, fish landing, water and fuel recharging and mooring area will be demarcated. 5. The island of Kaashidhoo lies at the eastern side of the Kardiva Channel, located 20 km north from the small Gaafaru atoll and 30 km southeast from Faadhippolhu. The formation consists of an approximately rectangular-shaped island that is situated on the southeastern side of a reef-fringed platform. Measuring 2.9 km in length and around 1 km in width, the island covers an area of 2.75 km2, making it the largest island of Male' Atoll and the fifth largest island of the entire Maldivian archipelago. The island is located at 04° 57' 20" N and 73° 27' 53" E. 6. The existing harbor facility is located at the north western side of the island facing the western quadrant. The site boundaries are harbor area and entrance channel area. The harbor facility will undergo maintenance dredging; a breakwater will be constructed at the western side of harbor. Maintenance dredging will not be required for the entire length of entrance channel, but only at the shallow areas. 7. The existing harbor footprint will not be changed due to the proposed project (area loss by putting near quay wall in front of existing one will be adjusted from breakwater area), side quay wall will be constructed at existing foot print, and a new breakwater will be constructed (existing harbor facility is without a breakwater). Therefore the existing design of the harbor will remain as it is. The length of the harbor after completion of renovation works will be 215.5m and width 85m. The existing entrance will be used after maintenance dredging. The length of entrance channel is approximately 2500m, while width is 30m. The harbor basin and entrance channel will have a depth of -3MSL after completion of the restoration works. 8. The harbor will have a total length of 252.18m of breakwater at the western side. The breakwater will be constructed of armor stones and remains of demolished quay wall (where significant damage is observed) will be used as core. The side quays will have a total length of 120m of type 2 design quay wall, while the main quay will have a length of 215.5m. 9. Dredge material removed from the harbor basin (maintenance dredging works) and entrance will be initially stockpiled near harbor area since part of the material will be required during construction works. Part of the sediment will be used for back filling the area in between the existing quay wall and new quay wall and for filling the geo textile bags of breakwaters and side quays. Approximately 6,000m3 (used as core for breakwater, filling area in between new and old quay wall and filling geo-textile bags of main quay wall and side quay walls) of sediment will be used of the construction work while rest will be disposed southern side of harbor (1000m3). The sediment will be transported to the disposal sites on trucks, although initially sediment will be stockpiled near harbor area for construction purposes. Approximately 9,000m3 of dredge material will be removed from the harbor basin and entrance channel. 10. Two sites are surveyed for assessing the reef condition, site one was located at the northern side of entrance near mouth of entrance (westerns side of reef) while site two was located at sea grass meadow western side of harbor. Live coral cover at site one was approximately 20%, while at site two was very low. 11. It is important to note that the most significant impact associated with the project would be impact on the marine environment from sedimentation. Dredging and excavation often carry a heavy load of sediments increasing sediment load in the water column causing discoloration due to suspended sediments of the impact area for a prolonged period. Since the project is a restoration project, the extent of sediment plum will be limited at the harbor basin area, while entrance channel area required for deepening is within the lagoon area and far from reef flat area. 12. Since the proposed project is restoration project, environmental impacts associated with the proposed project are considered minor to moderate. 13. Mitigation measures are provided in the report for impacts that were categorized minor to moderate. Impact mitigation measures and monitoring is carried out to compare predicted and actual impacts occurring from project activities to determine the efficiency of the mitigation measures. It has to be noted that environmental monitoring has not been done since the completion of harbor, and extent of changes to habitat, live coral cover and shoreline is not known. Even though the project is not envisaged to cause impacts on shoreline (since construction will be done at existing footprint), it is important to monitor shoreline changes. 14. The main issue raised in the consultation meeting at Kaashidhoo by the IDC was the issue of entrance channel, expansion of harbor and shifting of harbor 30ft inside basin area to widen the harbor front road. 15. With due consideration to main environmental components identified and the magnitude of impacts on these components from the proposed developments, the consultant concludes that the project components and designs are feasible and appropriate mitigation measures are given to correct and minimize unfavorable environmental consequences. Furthermore, the public and community consultation responses were in favor of the project due to the socioeconomic benefits foreseen to the community from a functional harbor.

    EIA report for restoration of HA Hoarafushi harbour under construction of harbours for Tsunami Victims Project
    (2010-08-19) Land and Marine Environmental Resources Group
    1. This Environmental Impact Assessment (EIA) report is to fulfill the regulatory requirements under the Environmental Protection and Preservation Act of Maldives prior to the proposed harbor restoration at Hoarafushi in Ha Atoll. 2. Hoarafushi harbor restoration project is part of the Construction of Harbors for Tsunami Victims Project. This restoration project involves repair of harbors at 10 islands. The project is funded by a joint loan taken from Islamic Development Bank (IDB), the Saudi Government and Organization of the Petroleum Exporting Countries (OPEC) by the government of Maldives. The design consultancy was awarded to Alhabshi Consultants Office, a Kuwaiti Company in association with Riyan Pvt Ltd (a Maldivian company). The Agreement for consultancy was signed on 6th November 2008 between the Government of Maldives and Alhabshi Consultant. 3. Project proponent of the proposed harbor restoration project is Ministry of Housing, Transport and Environment. The project was bided as a design and consultancy project. The main design consulting company Alhabshi Consultants is assigned to carry out the design works, preparing tender documents, carrying out EIAs and construction phase supervision consultant. 4. The proposed development project involves renovation and restoration of Hoarafushi harbor. During the December 2004 Indian Ocean Tsunami, Hoarafushi harbor facility received extensive damages. These include damage to harbor protection walls, side walls and quay walls. Under the proposed project, new quay wall (concrete sheet piles, L section) and breakwaters (armor rocks) will be constructed at the existing foot prints. The harbor basin will also undergo maintenance dredging to -3MSL. Since the proposed project is only a restoration project, size of the harbor basin will not be increased. The concept plan is formulated in light of the new third generation harbor concept which is focused at functionality of the harbor. In this regard harbor usage components such as passenger embarking/disembarking, loading unloading area, fish landing, water and fuel recharging and mooring area will be demarcated. 5. Hoarafushi (06° 58' 53" N and 72° 53' 48" E) is located on the west side of Ihavandhippolhu atoll, 318 km from Male’. It is approximately 27km from Dhidhdhoo which is the capital of Ha Alifu Atoll (northern most atoll in Upper North province. The existing harbor basin and facility is located at the eastern side of the island facing Ihavandhippolhu atoll basin. The project boundaries are the harbor front area, either side breakwaters, eastern side seawall and breakwater section at the harbor entrance channel. Under the proposed project maintenance dredging will be done at the basin and entrance area where necessary and this activity will generate sediment plumes east and north eastwards. Dredged material removed during the maintenance dredging works will be disposed at the western side of the island where a bay shape area is observed (surplus after reuse during reconstruction work). 6. The existing harbor footprint will not be changed due to the proposed project, breakwaters and quay wall will be constructed at existing foot print area (apart from small section of breakwater at the western side of the harbor). Therefore the existing design of the harbor will remain as it is. The length of the harbor after completion of renovation works will be 361m and width of 88m. The length of entrance channel is approximately 150m, while width is 30m. The harbor basin will have a depth of -3MSL after completion of the restoration works. 7. The harbor will have a total length of 523m (including side quay walls) of quay walls and 324m of rubble mound breakwater. The rubble mound breakwater will be constructed of demolished material from existing breakwaters while the main breakwaters will be of armored rocks. A small section of existing revetment wall will be retained at the eastern side of the harbor which is in good condition. 8. Dredge material removed from the harbor basin (maintenance dredging works) will be initially stockpiled near harbor area since part of the material will be required during construction works. Part of the sediment will be used for back filling the area in between the existing quay wall and new quay wall and for filling the geo textile bags of breakwaters and side quays. Part of the sediment will also be used to level the harbor front area here a large scour pit is observed. Approximately 22000m3 of sediment will be excavated from deepening of harbor basin. A fair proportion of this sediment would be used for several aspects of harbor repair and construction work while any remains will be disposed at the erosion prone areas at the eastern side of the island. The sediment will be transported to the disposal sites on trucks, although initially sediment will be stockpiled near harbor area for construction purposes 9. Existing environment was examined to identify significant environmental components that would be affected and to establish a baseline condition of the site. Available and relevant literature on environmental impacts associated with similar projects was evaluated to identify possible impacts. Oceanographic data and information on local hydrodynamics were qualitatively assessed to determine the current pattern around the island which was based on monsoonal wind patterns, wind generated waves, tidal flushing, geographic setting, the topography of the lagoon and shape of the shoreline. 10. The harbor front area surveyed during the field visit had live coral cover less than 5%. 11. It is important to note that the most significant impact associated with the project would be impact on the marine environment from sedimentation. Dredging and excavation often carry a heavy load of sediments increasing sediment load in the water column causing discoloration due to suspended sediments of the impact area for a prolonged period. Since the project is a restoration project, the extent of sediment plum will be limited. The existing damaged breakwaters will act as bunds therefore limiting the spread of sediment fines. 12. Since the proposed project is restoration project, environmental impacts associated with the proposed project are considered minor to moderate. The significant environmental components that are likely to be affected are the coral community established on the reef flat and changes due to maintenance dredging works. 13. Mitigation measures are provided in the report for impacts that were categorized minor to moderate. Impact mitigation measures and monitoring is carried out to compare predicted and actual impacts occurring from project activities to determine the efficiency of the mitigation measures. It has to be noted that environmental monitoring has not been done since the completion of harbor, and extent of changes to habitat, live coral cover and shoreline is not known. Even though the project is not envisaged to cause impacts of shoreline (since construction will be done at existing footprint), it is important to monitor shoreline changes. 14. The IDC and harbor committee stated that the size of harbor has to be increased due to increase of vessels and size of vessels. Since the project is a restoration project funded by a loan the scope of work is limited. Although the community stressed the issue of harbor expansion the community was in consent to the proposed project. The existing harbor facility was badly damaged during the 2004 tsunami and is in urgent need of repairs. 15. With due consideration to main environmental components identified and the magnitude of impacts on these components from the proposed developments, the consultant concludes that the project components and designs are feasible and appropriate mitigation measures are given to correct and minimize unfavorable environmental consequences. Furthermore, the public and community consultation responses were in favor of the project due to the socioeconomic benefits foreseen to the community from a more functional harbor.

    Environmental impact assessment report harbour development works at Rashdhoo, Alifu Alifu Atoll
    (2010-01-01) Land and Marine Environmental Resources Group
    This Environmental Impact Assessment (EIA) report is to fulfill the regulatory requirements under the Environmental Protection and Preservation Act of Maldives prior to the proposed harbor development at Rashdhoo in Alifu Alifu Atoll. Rashdhoo harbor concept design was formulated after meeting by MHTE, president of Maldives and the island community during the visit by president to Rashdhoo. Large natural deep lagoon and entrances are located at the northern quadrant of the island, which is used by the island community as the main access point to the island. The proposed project involves construction of a 228.6m by 78.7m harbor facility at the northern side of the island, located west of the old jetty head. L shaped concrete elements (precast) will be used for the quay wall structure; and armored rocks will be used for the break waters. The harbor development will be funded by the government of Maldives under the Access Improvement Programme implemented by the Ministry of Housing, Transport and Environment (MHTE). The harbor design incorporates the new harbor design concept (third generation harbor), which includes separate loading and unloading area constructed as a T jetty. Part of the basin will include existing deep lagoon area (eastern side of harbor) the rest will be located on shallow lagoon flat. Sediment excavated to deepen the harbor basin would be disposed at either side of the harbor and back of the harbor (backfilling of the quay wall). The estimated volume of dredged sediment is sufficient for filling either side of the harbor and behind the quay wall only. This report provides the results of the fieldwork carried out on Rashdhoo in September 2009 and January 2010 and associated public and community consultations that followed. The environmental impacts arising from the proposed developments are predicted based on the findings of the fieldwork along with the activities that cause these impacts during the construction and operational phases. Existing environment was examined to identify significant environmental components that would be affected and to establish a baseline condition of the site. Available and relevant literature on environmental impacts associated with similar projects was evaluated to identify possible impacts. Oceanographic data and information on local hydrodynamics were qualitatively assessed to determine the current pattern around the island which was based on monsoonal wind patterns, wind generated waves, tidal flushing, geographic setting, the topography of the lagoon and shape of the shoreline. Three sites were selected to assess reef benthos and selected fish community as the baseline data which would also be considered for long-term monitoring program to monitor the impact of the project. In addition to the fish and benthic surveys, seawater quality was assessed in the lagoon at the north western side of the island (proposed harbor area). The substrate of the lagoon is mostly abiotic. The area to be dredged is dominated with sand and rubble. It is important to note that the most significant impact associated with the project would be impact on the marine environment from sedimentation. Dredging and excavation often carry a heavy load of sediments increasing sediment load in the water column causing discoloration due to suspended sediments of the impact area for a prolonged period. However, there is no established coral community that would be directly affected except perhaps a few isolated coral colonies in the lagoon area. Indirect impact area has high cover of live coral. Environmental impacts associated with the proposed project are considered moderate to major. The significant environmental components that are likely to be affected are the coral community established on the reef flat and changes to littoral drift and near-shore coastal hydrodynamics. Impact on the coral community from sedimentation as a result of excavation is inevitable. Mitigation measures are provided in the report for impacts that were categorized moderate to major. Impact mitigation measures and monitoring is carried out to compare predicted and actual impacts occurring from project activities to determine the efficiency of the mitigation measures. The environmental monitoring proposed here is to determine the effectiveness of the mitigation measures and long term change to the benthic community, especially coral community, where the baseline information was collected. The participants of the consultation meeting held at Rashdhoo stressed the need for mitigation the severe erosion problem at the western side of the island. With due consideration to main environmental components identified and the magnitude of impacts on these components from the proposed developments, the consultant concludes that the project components and designs are feasible and appropriate mitigation measures are given to correct and minimize unfavorable environmental consequences. Furthermore, the public and community consultation responses were in favor of the project due to the socio-economic benefits foreseen to the community from the harbor.

The proposed development project involves renovation and restoration of Ga Dhevadhoo harbor. Under the proposed project, new quay wall (concrete sheet piles, L section) and breakwaters (armor rocks) will be constructed at the existing foot prints. The harbor basin will also undergo maintenance dredging to -3MSL (where necessary). Since the proposed project is only a restoration project, basin size will not be increased. The concept plan is formulated in light of the new third generation harbor concept which is focused at functionality of the harbor. In this regard harbor usage components such as passenger embarking/disembarking, loading unloading area, fish landing, water and fuel recharging and mooring area will be demarcated. Ga Dhevadhoo is located at Ga atoll, 400km from Male’. It is just about 28km from Kaadedhoo Airport. Nearest inhabited island is Ga Nilandhoo (24km at eastern side) and GDh Thinadhoo (26km at the western side of Dhevadhoo). In terms of geographic coordinates, it is located at 00° 33' 26" N and 73° 14' 32" E. Nearest islands are Hagadhoo approximately 4.5km south west and Funamudua approximately 5km west of Dhevadhoo. The existing harbor facility is located at the western side of the island, while access to the harbor is via an entrance channel south western side of harbor. The project boundaries are the harbor front area, either side breakwaters, eastern side seawall and entrance area). Under the proposed project maintenance dredging will be done at the basin and entrance area where necessary and this activity will generate sediment plumes west wards. Dredged material removed during the maintenance dredging works will be reused for construction. The existing harbor footprint will not be changed due to the proposed project, breakwaters and quay wall will be constructed at existing foot print area (apart from small section of breakwater at the southern side of the harbor for protection of entrance channel). Therefore the existing design of the harbor will remain as it is. The length of the harbor after completion of renovation works will be 149.2m and width 95m. The length of entrance channel is approximately 63m, while width is 40m. The harbor will have a total length of 190m of breakwater at the western side. The breakwater will be constructed of armor stones and remains of existing breakwater as core The side quay will have a total length of 190m of type 2 design quay wall, while the main quay will have a length of 149.2m. Approximately 1500m3 of dredged material will be generated by the maintenance dredging works. This sand will be reused during construction stage, thereby avoiding the need for disposal. Existing environment was examined to identify significant environmental components that would be affected and to establish a baseline condition of the site. Available and relevant literature on environmental impacts associated with similar projects was evaluated to identify possible impacts. Oceanographic data and information on local hydrodynamics were qualitatively assessed to determine the current pattern around the island which was based on monsoonal wind patterns, wind generated waves, tidal flushing, geographic setting, the topography of the lagoon and shape of the shoreline. The reef flat area in front of harbor was dominated by tabulate life forms of Acropora and massive life forms of Porites. Large table corals and branching coral colonies were abundant at the area. Numerous small table coral colonies were observed behind the reef flat area dominating the rocky back reef towards the lagoon. The reef slope area was dominated by large table corals and branching forms of acropora. Live coral cover at the reef flat area is approximately 45%, from which 30% is estimated to be Acroporids. Large porties bommies were mainly observed just off the crust area at the reef slope. Other live coral generas observed are Pocillopora, Pavona, Echinopora, Goniastrea, Psammacora and Favites. It is important to note that the most significant impact associated with the project would be impact on the marine environment from sedimentation. Dredging and excavation often carry a heavy load of sediments increasing sediment load in the water column causing discoloration due to suspended sediments of the impact area for a prolonged period. Since the project is a restoration project, the extent of sediment plum will be limited at the harbor basin area. Since the proposed project is restoration project, environmental impacts associated with the proposed project are considered minor. The significant environmental components that are likely to be affected are the coral community at harbor front area. Mitigation measures are provided in the report for impacts that were categorized minor to moderate. Impact mitigation measures and monitoring is carried out to compare predicted and actual impacts occurring from project activities to determine the efficiency of the mitigation measures. It has to be noted that environmental monitoring has not been done since the completion of harbor, and extent of changes to habitat, live coral cover and shoreline is not known. Even though the project is not envisaged to cause impacts to shoreline (since construction will be done at existing footprint), it is important to monitor shoreline changes. One of the main issues highlighted by most of the participants of the meeting held at Dhevadhoo as part of stakeholder consultation was the issue of repeated surveys and no action. The community strongly feels that the restoration project would only ease the accessibility issue but will not resolve the issue of accommodating all the vessels used by the community especially the fishing fleet. The participants of the meeting stated that the harbor facility is in need for expansion (800x300ft). The participants stated that due to location of Dhevadhoo many trade vessels and Safaris use Dhevadhoo harbor as a transit point, therefore the harbor is always crowded. Also during fishing season the harbor is used by fishing vessels from other atoll as well. Due to this reason the community feels very strongly that the harbor needs to be expanded. Since resorts are opening near the island, additional usage of harbor is envisaged therefore burden on harbor will increase. Overall the IDC and harbor committee was in favor of the project and very little issues apart from extension of harbor were raised during the stakeholder meeting With due consideration to main environmental components identified and the magnitude of impacts on these components from the proposed developments, the consultant concludes that the project components and designs are feasible and appropriate mitigation measures are given to correct and minimize unfavorable environmental consequences. Furthermore, the public and community consultation responses were in favor of the project due to the socio-economic benefits foreseen to the community from a functional harbor.
