|Abstract: ||This report discusses the findings of an Environmental Impact Assessment for the proposed
development of a beaching area in HA. Dhidhdhoo. The project is proposed by Ministry of
Housing and Infrastructure.
At present, unavailability of space has forced boat owners to travel great distances to do small
scale servicing to boats. In cases where boats are beached on Dhidhdhoo, being too close to
residential areas has made these activities a public nuisance and a health hazard. The project
aims at providing a suitable space for boat owners of Dhidhdhoo and nearby islands for vessel
beaching and related work on the island away from residential areas. The proposed project
entails dredging a 24m by 266m access channel, 110m by 76m manoeuvring area and
reclamation of 0.54Ha at the southwest side of the island.
There are very few practical alternatives to the proposed project; alternatives to reclamation
shape and location are assessed in the report.
Environmental impacts were assessed for both the construction and operation phase of the
project. Most of the environmental impacts of the project have been identified as positive
resulting mainly from improved socio-economic situation of Dhidhdhoo. The main negative
environmental impact of the project is identified to be the possible movement of low to
moderate levels of sediment on the reef during dredging and reclamation. Movement and
settlement of fine sediments are expected to occur on the reef flat to a small degree. However,
effects of this would not be severe as sediment plume is not expected to last longer and live
coral cover at the location is minimal. Overall, the negative environmental impacts of the
project are short-term and of moderate significance while long term socio-economic benefits
are numerous. Hence the impact matrices done for the project indicates a net positive impact.
Impact mitigation measures are few. In order to mitigate movement of sediment plume onto
the reef, bunds around reclamation area and creating settlement ponds during reclamation is
Regular environmental monitoring and reporting is an essential element of the EIA process.
During the construction phase, in-situ monitoring of total suspended solids and turbidity is
usually undertaken in dredging and reclamation projects to ensure that water quality criteria
are met and sedimentation on the reef does not occur. It is recommended to incorporate these
into an island-wide monitoring programme, which is not within the scope of this EIA report.
In conclusion, it appears justified from a technical and environmental point of view to carry
out the proposed project to develop a beaching area in Dhidhdhoo. However, before start of
construction phase, the consultants recommend evaluating alternative reclamation shape
proposed in this report; as to reduce potential impact of interrupting longshore sediment
