| dcterms.abstract | The purpose of this document is to fulfil the requirements to get necessary environmental
clearance from the Environmental Protection Agency to carry out the proposed shore protection
and jetty construction projectin Holiday Island Resort, South Ari Atoll. The proponent of this
project is Villa Shipping and Trading Co. Pvt. Ltd.
The main rational for the project is to improve the access facilities for service vessels to Holiday
Island, and mitigate coastal erosion. The eastern end of Holiday Island faces severe erosion in
some areasmainly due to the presence of deep dredged areas to the east (between Holiday Island
and Maamigili Island). On the other hand, the service jetty, located south of the eroding
coastline, requires immediate attention as sediment accumulation is occurring in the area.
The project involves construction of a 285m long alongside quay wall using sheet piles,redredging
of an area of 115 m by 175 m adjacent to the quay wall to allow access for service
vessels and maintenance dredging of the 120 m by 25 m reef entrance channel. The area between
the sheet piled quay wall and the existing shoreline will be backfilled using the dredged material.
The existing beach material on the eastern end of the island will be used for beach replenishment
on the northern side to mitigate erosion occurring in the area. Armour rock boulders will be
placed on either end of the quay wall for shore protection. Material from channel maintenance
dredging will be placed alongside it.
All project activities will be in conformance to the laws and regulations of the Maldives, and
relevant international conventions that Maldives is party to. The key laws and regulations
applicable to this project are: Environmental Protection and Preservation Act, Environmental
Impact Assessment Regulation 2012 and the Tourism Act.
The proposed project site has already been dredged, and no live corals were observed in the area.
The bottom is composed of fine white sand. High levels of sedimentation and turbidity, as well
as recently dead corals covered in algae and sediment were observed in the lagoon areas to the
north and south of the island shore. Few Acropora and boulder corals were observed in the
lagoon area to the south of the island. High sedimentation was also observed in the reef, where
live coral, mainly Acropora nasuta, Acropora tenius and corals belonging to Family Pocillopora,
composed about 29% of the benthic cover.
Significant impacts of this project during construction phase of the project are the potential
impact of sedimentation on the marine water quality and consequent impact on marine life,
direct loss of marine life within the project footprint and the health and safety risks to
construction workers. All these impacts can be minimized with proper mitigation measures
recommended in the report
The main mitigation measures include carrying out construction activities during low tide hours
and calm weather, deployment of silt screen or construction of bunds where appropriate to
reduce sediment dispersal and avoid adverse sedimentation impacts and proper supervision of all
activities by qualified personnel. The work schedule and duration will also be planned to avoid
disruptive weather conditions and complete construction activities in the shortest time possible.
The alternatives evaluated for the project are project design, service jetty location, quay wall
construction material, dredging methods; dredge waste disposal sites, sediment containment
measures and alternative sheet piling technology. The “No Project” option has also been
explored and this option is not deemed preferable, given the condition of the existing service
jetty and the need for erosion management along the north eastern coastline.
The use of a cutter suction dredger is the preferred option for dredging method, since it is
available on site and reduces the time period required for completion of project activities.
Monitoring plan is designed to assess any changes to the coral reef environment of the island,
coastal changes and depth variations of jetty area as well the marine water quality as these are
the key areas that could be impacted from this project.
The management plan for this project is designed to produce a framework for anticipated
impacts, including practicable and achievable performance requirements and systems for
monitoring, reporting and implementing corrective actions. In addition, it provides evidence of
compliance to legislation, policies, guidelines and requirements of relevant authorities.
In conclusion, this project has been designed in conformance to the relevant laws and regulations
of Maldives. The most significant impacts are expected to be short-term impacts on the marine
water quality, coral reef and lagoon bottom habitats. However, mitigation measures have been
proposed to adequately minimise these significant impacts | - |
