|Sotogrande, Dominican Republic
Sotogrande at Cap Cana is an exclusive private
residential development over approximately 25
hectares of property within the Cap Cana resort.
The master plan envisioned a beach along
approximately 300 meters of limestone (ironshore)
shoreline. Coastal Systems conducted a comprehensive
coastal engineering study to evaluate waves, winds, water
levels and sediment transport in the area to design an inland,
protected beach system. Historical hurricane tracks along
with wind/wave statistics were compiled, and a wave
propagation study was conducted utilizing the DHI MIKE-21
SW numerical model to determine design wave conditions for
normal conditions at the Project shoreline. The effects of
extreme wave conditions from hurricanes and other coastal
storm events were also evaluated with the propagation study.
The interior beach was designed as a “pocket” beach that
created a beach where complex coastal processes along a
rocky shoreline would prevent the creation of traditional
beach shoreline. The pocket beach was created by cutting
through the limestone shoreline at strategic areas with
specific dimensions, horizontal and vertical, to allow
sufficient wave energy into the newly created lagoons.
Breakwaters were created by sculpting the ironshore to
provide a natural, aesthetically pleasing cut rock inner
shoreline. Lagoons were excavated interior of the shoreline to
optimize the pocket beach area and design slopes for the
beach. Cut areas for swimming were designed, and the “sills”
cut into the ironshore allowed sufficient wave energy inside
the pocket beaches to maintain the littoral zone and to
maintain sufficient water quality. The cuts in the ironshore
were designed to optimize the amount of wave energy
entering the lagoon.
Coastal Systems worked closely with the upland architects
to design the beach as coordinated with the upland site plan
and associated residential development. Construction plans
were prepared, and Coastal Systems provided construction
administration services throughout construction.
