Prevention of Further Oiling of Fort Livingston
Oil is expected to continue to arrive on the shores of Grand Terre Island over the coming months. The breakwater on the gulf side of Fort Livingston provides an opportunity to prevent a significant amount of additional oil from reaching the fort. If resources are available, additional sand could be added to the breakwater to help prevent the oil from penetrating the riprap in the breakwater and reaching Fort Livingston. This sand would fill gaps and voids in the breakwater, trapping oil. The continued use of booms is also recommended.
Additional sand would need to be dredged from the gulf side of the breakwater, and preferably some distance from the island, as remnants of the fort lie submerged in the waters within the breakwater and are also likely to be found beyond the breakwater in Barataria Pass. Bagged sand could be used to help stabilize the loose, dredged sand added to fill gaps in the breakwater.
It is likely that such an approach would only be effective until a large storm washes the additional sand from the breakwater, or dislodges sand bags. With the development of La Niña conditions, it is expected that there will be an active hurricane season this year. The potential environmental issues involved in dredging sand should be considered in determining the most appropriate source of sand.
At the time of Hurricane Katrina, the island was the site of several points of interest:
- Fort Livingston
- The Louisiana Department of Wildlife and Fisheries’ (LDWF) Lyle St. Amant Marine Research Lab (closed after Hurricane Gustav, 2008)
- Two Coastal Wetlands Planning, Protection and Restoration Act (WPPRA) projects that were sponsored by the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service and the Louisiana Department of Natural Resources (LDNR.)
