"Louisiana's proposed $2.5 billion Mid-Barataria Sediment Diversion, designed to reconnect the Mississippi River with the Barataria Basin to create as much as 21 square miles of wetlands by 2070, was awarded key permits by the Army Corps of Engineers on Monday that could allow construction to begin in March 2023.
The approved environmental permits and a permit allowing the project to impact levees and shipping on the Mississippi River were announced in a news release on Monday afternoon.
The "record of decision" documents include a variety of special conditions the state must comply with during and after construction. The state must measure the effects of the diversion's operation on fisheries, including threatened and endangered species; its effect on bottlenose dolphins and on rebuilt wetlands adjacent to the diversion; and any flooding impacts the project has on local communities. It must also assure that the diversion opening does not impact shipping."
