TRINITY-EAST ISLAND, La. — Dredges, pumps and bulldozers are at work on Louisiana's biggest barrier island restoration yet, a $167 million project using BP oil spill money.

Pipelines are pumping sand 15 miles to build 1,100 acres of marsh, dune and beach on three barrier islands and a headland, The Courier reports. Work began in summer 2019 and is expected to be complete in January.

"It's really good to be out here and see first-hand the work that has taken place," Gov. John Bel Edwards said during a visit Monday to Trinity-East Island. "We have to do the most critical work first, and that's why we're standing on the barrier islands because this the first line of defense against approaching storms."

Trinity-East is a chunk eroded away from Trinity Island, one of several remnants left after a hurricane split a 25-mile-long resort island called Isle Dernire — Last Island — in 1856, and other storms followed.

At one point, project manager April Newman told Edwards and other state and local officials they were standing where a canal had cut through the island, hastening erosion.

The project off Terrebonne Parish is using 9.2 million cubic yards of sediment — enough to fill the Superdome more than twice — at this island, Timbalier and West Belle islands to the east, and a spit of land called West Belle Headland. Only Trinity-East used to be part of the resort island. Some of Lost Island's remnants are now part of a state wildlife refuge.

Trinity-East will wind up with 2.5 miles of continuous shoreline and 263 acres of beach habitat, according to the coastal agency. The work on Timbalier Island will fill inlets gouged out by storms and build a 2.8-mile stretch of beach and marsh covering 409 acres. The West Belle Headland project is being redesigned because of damage from Hurricane Zeta, which hit Louisiana in October. It could add about 525 acres.

Other barrier island restoration projects include 400 acres at North Breton Island and about 32 acres at Queen Bess Island.

Raccoon Island, at the western end of what are now collectively called the Isles Dernires chain, was restored earlier.

The project Edwards visited Monday is among many in Louisiana using money that BP paid after the 2010 oil spill. This grant came through the National Fish and Wildlife Foundation.

BP estimates that it has paid more than $69 billion for response, cleanup, economic claims, government payments, settlements and restoration from the spill.

"The Terrebonne Basin project continues the incredible restoration of our entire barrier island chain, restoring some of Louisiana's most vulnerable landscapes stretching from Whiskey Island below Houma and Cocodrie to Sandy Point near Venice in Plaquemines Parish," said Chip Kline, chairman of the Louisiana Coastal Protection and Restoration Authority.

"In places without barrier islands, we're rebuilding and fortifying our beaches and shorelines all the way west to Cameron Parish," Kline said. "This perimeter defense works in conjunction with the vast areas of land we're restoring in our major basins to strengthen protection for coastal and inland areas alike."
