Perhaps
the most successful beach maintenance program in Florida, the City
of Delray Beach, conducted the 4th periodic renourishment of the
original beach nourishment project in February and March of 2002.
The dredge contractor, Bean-Stuyvesant L.L.C., using their dredge
the Meridian competed the project in 58 days. The 1.7 mile long project
resulted in the placement of over one million cubic yards of sand,
protecting the design section of the beach project.
Coastal Planning & Engineering’s geologists identified
a sand source approximately 2500 feet directly offshore for use
in the renourishment project. Biologists from CPE have also mapped
the
offshore reefs to protect the reef habitat, building in wide
buffer zones around the reefs to avoid accidental damage.
In addition, a gap in the barrier reef system was mapped, and used
by the dredge contractor to ingress and egress into the project area
with the dredge and other vessels, avoiding transport over the sensitive
reef system. The project design developed by CPE includes a consideration
of an extensive data record of past beach monitoring results to develop
a plan which addressed hot spot areas of erosion.
Paul Dorling is project manager for the City of Delray Beach. The
construction contract had a unit cost per cubic yard of sand in place
of $2.60 with a mobilization/demobilization fee of $968,500, for
a total cost of $3,882,210, including beach tilling.
