The greater Lafitte area, located in Jefferson Parish along the Barataria Bay Waterway approximately 13 miles south of New Orleans, has long been victim to flood events from rainfall, tropical storm surge, and high tides. The Lower Lafitte Tidal Protection system includes 10 planned projects spanning 30 miles of levees, floodwalls, and other protection measures that will support the communities of Lafitte, Barataria, and Crown Point.

Three of the projects, the Fisher School Basin Flood Risk Reduction project, the Rosethorne Tidal Protection project, and the Lower Lafitte Basin Tidal Surge project, have been completed or are underway.

Completed in May 2020, the Fisher School Basin Flood Risk Reduction project consists of 2.9 miles of concrete-capped steel sheet pile flood walls, earthen levees, and nine flood gates built along Bayou Barataria. The project connects to an existing back levee and is now at an elevation of 7.5 feet, providing flood risk reduction to the 453-acre Fisher School Basin. Built in two phases, the $33.5 million project was funded through a combination of a state surplus funds, Capital Outlay funds, and DOTD Statewide Flood funds.

Phase 1 of construction on the Rosethorne Tidal Protection project broke ground in September 2021 and, upon completion, is expected to provide additional protection for the community of Rosethorne in the event of a 10-year rainfall or tidal flood event. The $40.1 million project is a partnership between CPRA, the Lafitte Area Independent Levee District, and DOTD, consisting of the construction of 10,300 linear feet of concrete-capped floodwall and floodgates at a 7.5- foot elevation. The two phases of the Rosethorne Tidal Protection project are funded by state surplus and Capital Outlay funds, with Phase 2 receiving federal funding through the Gulf of Mexico Security Act (GOMESA).

The Lower Lafitte Basin Tidal Surge project broke ground in September 2023 and is designed to strengthen protection against tidal surge for the town of Jean Lafitte. The 3-mile-long levee project will include three swing gates, one roller gate, and more than 7,000 feet of concrete-capped floodwall; modifications to 7,300 feet of earthen levee; and new construction of 2,800 feet of earthen levee, all at a height of 7.6 feet. The $22.7 million project is a collaboration between the Lafitte Area Independent Levee District, CPRA, DOTD, and Jefferson Parish.
