|Pease Bay, Cayman Island
Coastal Systems International, Inc. provided coastal
engineering services to locate and design a
channel that would provide ocean access for boats
through the shallow nearshore to the offshore reefs
in Pease Bay. Pease Bay is a shallow lagoon separated from
the adjacent lagoons and the ocean by a fringing coral reef.
Coastal Systems conducted field investigations including
hydrographic surveys. Local wind and wave records, tide and
current patterns, historical storm data, and flushing
characteristics of the project area were analyzed to determine
the optimal configuration of the channel navigation but also to
minimize impacts to the adjacent reefs and seagrasses. Cost
alternatives were developed for the excavation of the channel
as well as designs for an adjacent recreational beach and pier.
Along the 535-foot shoreline, concepts were developed for a
recreational beach with a protected lagoon.
configurations were evaluated, including excavated lagoons
protected with rubblemound coastal structures. The
recreational pier was integrated with the designs, with one
configuration utilizing a portion of the proposed breakwater
for access. Conceptual plans were developed along with
engineering cost estimates to further evaluate the feasibility of
the shoreline improvements. The coastal engineering study
was compiled into an Environmental Impact Assessment
comprehensive report that was processed through the
Department of the Environment.
