Item Environmental impact assessment report for playground reclamation project GA. Dhandhoo(2013-02) Energy ConsultancyDhaandhoo is located on the eastern rim of G.A Atoll, approximately at 0° 37’ 15.88’’ N and 73° 27’ 43.78’’ E. Dhaandhoo has a population of 1949 and all areas of the island is populated. The island teams host their practice in a nearby island Nilandhoo. Since for each practice of the football team, the local players have to take a sea transport to Nilandhoo, the practicing is very inconvenient. The proposal to reclamation for the development of a football ground was proposed due to difficulties on land allocation. From the survey conducted to examine existing environment, the coastal environment shows well developed natural beach associated with beach erosion is some places along the west side of the island. In some places the beach rock can be seen. The mean coastal current was found to be 7.9cm/s. In the marine environment the coral cover found to be 16.3 percent and at the time of the survey, some fishes were observed in the vicinity. It is expected that the project will be completed within 150 days. The main components in this project include mobilization, dredging, construction of breakwater and quay wall and demobilization. The proposed area to be reclaimed is 0.72 ha. A total of 18000 m3 of sand needed to be mined from the borrow area, which is located Northwest of the existing harbor. The land reclamation would take place in the Southwest of the existing harbor. The most suitable alternative location for the borrowing area would be the existing harbor. However from the dredging of the existing harbor might not accumulate enough volume of sand to reclaim 0.72 hectors of land area required for the football field. An alternative location for the football field is the site that has been proposed for the land reclamation located at the Northwest of the harbor. However from the community consultation it was found the proposed dredging site is to be used as a commercial harbor in future. The main impact from this project to the environment was identified to be sedimentation and loss of some marine habitat. The main mitigation measures are carrying out the project during low tide and complete the project in a shorter period of the time.Item Environmental impact assessment report for harbor construction project Ga. Kon’dey(2013-02) Energy ConsultancyKon’dey is located on the south-eastern part of G.A Atoll. The proposed harbor is 91 m long and 61 m wide with a 28 m wide entrance. The basin will be 5 m deep at mean sea level. This is a small size harbor relative to harbors in more populated islands. The proposed harbor site is located at the existing harbor area on thewestern side of the island.Since the basin area is already excavated, it is expected that the material removed from the basin and the entrance will be just enough to backfill and to reclaim the quay wall of the harbor. For the breakwater, armour rocks will be loaded and transferred to site from stock pile using excavator. Before backfilling the quay wall, a geo-textile layer will be placed between the quay wall blocks and back filled sand. In the proposed project area there is an existing temporary harbor used by the island community. In the deep area the survey showed a depth of 4 to 5 meters from the mean sea level meanwhile inthe shallower region of the proposed harbor site has 1 to 2 meters from mean sea level. Marine water quality was assessed in four deferent locations from the proposed area. According to the data collected, the sea water over the proposed location is clear. It was found from the survey that the percentage of the coral cover is less than 2 percent due to the pre-dragging for the harbor use. The island has a very long shoreline with its natural beach intact. However in some areas where economic activities are taking place, the problem of beach erosion can be found. In such areas the beach has eroded up to and beyond the vegetation line. The mean coastal current was found to be 7.8cm/s. The main impacts to the environment from the project include sedimentation silt deposition and loss of habitats in the sites where excavated materials has to be deposited. For monitoring the impacts that may arise from the proposedhabour project, shoreline, vegetation line beach profile and live coral cover should be monitored. These impacts can be mitigated through proper project planning and by taking proper precautions.
