Hillsboro
Inlet, Florida
Coastal Systems International,
Inc. evaluated the coastal processes influencing the
inlet and developed a design for a channel deepening
project at Hillsboro Inlet. The project involved the
dredging of 300,000 cubic yards of material, a third
of which consists of rock. The design will improve navigation
and minimize impacts to longshore sand movement
by allowing the channel to serve as a sediment trap,
collecting southerly-moving material. Sand deposited
in the channel will be mechanically bypassed using the
district-owned hydraulic dredge. Permits were prepared
for and secured from Broward County Department of Planning
and Environmental Protection (DPEP) and the State of
Florida Department of Environmental Protection (DEP)
as well as the Army Corps of Engineers. Coastal Systems
also secured partial funding for the Inlet Management
Plan Addendum from the Florida Inland Navigation District
(FIND) and the DEP. Dredging construction documents
were prepared using information collected from jet probes,
hydrographic and marine resource surveys, and offshore
disposal site video mapping. Dredging specifications
were prepared and construction was completed in December
2003.
Construction administration services were provided,
including dredging contract payment surveys. Coastal
Systems also designed the near shore mitigation required
due to environmental impacts from the dredging.
