The dredge sucked the sand up at the borrow site, about 9 miles offshore, then brought the sand close to shore and linked to the pipe, finally pumped the sand from the dredge to the beach itself. The dredge pumped three cycles of sand per day for two-hour intervals. In the winter of 2011, C ASHMAN'S trailing suction hopper dredge Atchafalaya re-nourished the beach in Longboat Key. To fix these depleted beaches, periodic beach nourishment projects are scheduled in order to replenish sand along Longboat Key’s coastline in conjunction with the State of Florida Department of Environmental Protection (DEP) and other federal, state, county and local agencies. The result is areas of depleted beaches, some dangerously so, and pockets of beach compatible material located inside the inlet. This material gets transported from the beach and much of it ends up just inside the inlet. This pipeline will run parallel to the beach so they will be visible, however, sand ramps will be built over the pipelines to allow safe access from the beach to the ocean.Longboat Key, as many other South Florida beach communities, consistently loses its beach to tidal cycles, currents, waves and weather. Shore pipeline will be laid to allow for sand to be pumped from the offshore station to the active construction site. This equipment contains back up lights and alarms so it may be a bit noisy. Bulldozers, loaders, and excavators will be used in this process. How Will The Beach Nourishment Process Affect Me?Īny given section of beach might be shut down for 4 to 6 days to ensure public safety. Not only will beach nourishment protect the Banks from storms, it also allows more space for visitors and locals alike to spread their beach gear out without being on top of each other on nice beach days.
