Army Corps of Engineers presents plans for West Bank wetlands projects

The Army Corps of Engineers Tuesday night unveiled a variety of wetland-restoration projects that will serve as mitigation for the environmental impact caused by building levees along the West Bank in the aftermath of Hurricane Katrina. The projects would restore more than 885 acres of wetlands on the water side of the levee system, including filling in several abandoned oilfield canals in Jean Lafitte National Wildlife refuge, restoration of 85 acres of wetlands in Yankee Pond along Bayou Segnette, and restoration of 643 acres of bottomland hardwood wetlands and swamp at Lake Boeuf, near Raceland in Lafourche Parish. The mitigation plan also will eventually include restoration of wetlands in privately owned “mitigation banks,” which will compensate for habitat damage on the protected side of levees.
Corps officials did not provide a price tag for the West Bank projects during Tuesday’s meeting at the Westwego Ernest J. Tassin Senior Center.
However, at a January meeting in Vicksburg, Miss., New Orleans corps planners estimated spending about $252 million on restoration projects resulting from construction of the 160-mile levee system, including $79 million on east bank projects and $173 million on the West Bank.
The projects in the corps’ tentatively selected plan were chosen from more than 400 possible mitigation sites, many suggested by community members.
The projects will compensate for damage to natural areas caused by building the West Closure Complex, Mississippi River Co-located levees, Eastern Tie-In, Harvey to Westwego Levee, Lake Cataouatche Levee, Bayou Segnette Floodgate Complex, the Western Tie-In, and government-furnished borrow sites in Plaquemines, Jefferson and St. Charles parishes.
Corps officials discussed the restoration program in general terms before attempting to break Tuesday night’s audience of about 50 people into smaller groups to discuss individual projects.
Another idea in Jesuit Bend
But the owner of a large tract at Jesuit Bend in Plaquemines Parish objected, saying the format deprived the audience of hearing about his alternative to the corps plan.
George Howard is president of Restoration Systems LLC, a North Carolina company that operates mitigation banks and develops property as mitigation for private owners and government agencies nationwide. He said the company has developed 25,000 acres in nine states as mitigation projects.
Howard’s proposal would redevelop open water areas of his property as wetlands, which he said could be done more cheaply than the corps and would help protect Plaquemines communities from hurricane storm surges. He said it’s not necessary to treat his property as a mitigation bank.
Elizabeth Behrens, corps environmental manager for the levee mitigation plan, said the agency has chosen projects it believes best match damage done in the levee construction. Many of the smaller projects will be in or adjacent to the Barataria Unit of the Jean Lafitte National Historic Park because of damage done to park lands.
Those projects avoid the cost of buying land that’s already part of the park, or will result in purchased land being added to the park, she said.
Other projects were selected as a response to damage to the environmentally sensitive Bayou aux Carpes wetland area, which is protected by a provision of the federal Clean Water Act, that occurred during construction of the West Closure Complex at the junction of the Gulf Intracoastal Waterway and the Harvey Canal.
She said Howard’s property is still eligible for participation in the mitigation bank portion of the restoration program, whose projects won’t be chosen until later this year.
‘Geocrib’ project under way
The Lake Boeuf project, chosen to mitigate for general impacts to bottomland hardwood forests and swamps, was picked as the best environmental project of its size in the area, she said. The land bought for that project will eventually be turned over to the state’s nearby Lake Boeuf Wildlife Management area, and thus available for public use, Behrens said.
Another 50-acre project, already well under way, is at the “Geocrib” area separating the eastern edge of Lake Salvador from the Gulf Intracoastal Waterway in Jefferson Parish.
The individual projects will be aimed at rebuilding wet or dry patches of bottomland hardwood forests containing cypress and tupelo trees, freshwater marshes, or swamps, based on the damage to each type of habitat by the levee projects.
The mitigation bank projects will involve the corps buying “credits” from an authorized bank located within the West Bank levee area. The corps will issue a request for proposals to buy credits from the banks equivalent to the acreage it determines is needed to be rebuilt.
