The vast construction projects being carried out in Louisiana by the Army Corps of Engineers for flood protection and other infrastructure have so far not been delayed by the federal government shutdown, a spokesman said Thursday.

The Corps’ funding for such projects is typically set out over the course of several years, said Ricky Boyett, spokesman for the Corps’ New Orleans district. An extended shutdown could eventually have ramifications, but that remains unclear, he said.

Other duties, such as inspections and permitting, have also not been affected so far. Boyett said he was not aware of any permanent employees being furloughed for now in the New Orleans district.

“As of today, none of our mission areas or projects are currently paused or suspended,” said Boyett.

Current projects include the construction of an underwater levee, or sill, in the Mississippi River to block the seasonal arrival of saltwater moving upstream from the Gulf, which can affect drinking water. The sill, being built near Myrtle Grove in Plaquemines Parish, is about 20% constructed and is expected to be complete by Oct. 16.

Other major projects under construction include the West Shore Lake Pontchartrain levee and floodwall system being built in St. Charles, St. John the Baptist and St. James parishes, and the Comite River Diversion Project in East Baton Rouge Parish, among many others.

Nationally, the Corps says it “remains fully committed to supporting the American people, the economy and national security during the lapse in appropriations.”

It will “continue to carry out mission-critical activities that directly support national security and the economy, including the operation and maintenance of locks, dams, hydropower facilities, and waterborne navigation systems,” it said in a statement.
