Our client plans to make Leeward Cut and Leeward
Going Through open to mega-yacht navigation. High
grade beach sand dredged from the channel would be
applied to Emerald Point as the first phase in its
development. Emerald Point is at the end of Grace
Bay, one of the most scenic beaches in Turks and Caicos
Islands and the entire Caribbean.
The project site is in sensitive environmental area
featuring superb diving, near Princess Alexandra Nature
Reserve and Pelican Reef. The client and the Turks
& Caicos Islands Department of Environment & Coastal
Resources (DECR) sought to minimize environmental impact.
Water turbidity was of particular concern.
Working with our client, DECR, and the design
engineer, Devcon Ltd. proposed a solution with 3
settling ponds to allow dredged material to separate
from the seawater. As water travels through the
system, it becomes progressively clearer. At the
end of the settling system is a rock filter, which
encourages further separation and dissipates energy from
the falling water to prevent erosion. The final
step is a fabric silt barrier before returning clear
water to the sea.
The project encompassed a large 35 acre site, and
Devcon had the luxury of using much of the area for
material accumulation. These turbidity mitigation
techniques retain the maximum amount of high grade beach
sand for our client and provide the best outcome for
marine life. This project is an example of our
commitment to environmental stewardship.
