Key
Biscayne, Florida
Coastal Systems International, Inc. developed a long-range
beach management plan to address the erosional shoreline
along the Village of Key Biscayne, Florida. In order to
develop the plan, the engineering team analyzed the physical
processes influencing the project such as winds, waves,
tides and storm impacts. These processes were evaluated
to determine the erosional patterns, design criteria,
and design life. The resulting project expanded the
beach and created a dune, which required approximately
120,000 cubic yards of sand obtained from an offshore
borrow area. The newly constructed dune was vegetated
with a variety of native dune species and now connects
the dune systems of the state and county park north and
south of the project site. Construction took place over
the summer of 2002, during which Coastal Systems provided
administration services.
 The
borrow area and project site are located within an area
of dense seagrass. To minimize adverse impacts to local
resources, the seagrass communities offshore of the
site, near the borrow area, and along the pipeline corridor
were mapped and categorized. The geographic locations
of the offshore resources were utilized during the design
phase to minimize impacts. These sensitive areas were
also monitored prior to, during, and after construction
to detect any impacts associated with the project.
