Corps finalizing Industrial Canal lock study as some residents brace for disruption

The U.S. Army Corps of Engineers is winding up a three-year study phase of its plan to replace the Industrial Canal Lock, located just north of the St. Claude Avenue Bridge. While the study won’t end until December, the Corps already believes its tentative selection for replacing the lock is the best in a narrow range of options for easing inland waterborne traffic. But some New Orleans residents say they’re outraged that the Corps is still considering the project, which has been planned for decades.

They’re pushing to have the lock moved out of the Industrial Canal in the heavily-populated 9th Ward and rebuilt somewhere else, citing the huge traffic problems and flood risk such a project could cause in the area.

Construction on such a replacement lock could take 13 years — or much longer, opponents warn. And they have little faith in the ability of the Corps to accomplish the replacement without serious community disruption. They also question the value of the project, whose cost is estimated by the Corps at more than $951 million.

But the Corps says it is long past time for a new lock on the Industrial Canal, known formally as the Inner Harbor Navigation Canal.

The lock and the canal are part of the Gulf Intracoastal Waterway, which winds along the coast from Texas all the way to the East Coast and links to the Mississippi River via the Industrial Canal. Shippers on the GIWW must use a lock because the water levels of the river are higher than sea level in the New Orleans area.

The lock in place now was built by the Port of New Orleans in 1923. It’s narrow, just 75 feet wide and 640 feet long.

“It’s at a crossroads, a key crossroads, linking the west part of the Intracoastal Waterway to the eastern part,” said Jim Stark, president of the Gulf Intracoastal Canal Association, which represents inland shipping interests. “It’s critical for cargoes moving both ways that support the industries we work with on a daily basis.”

The Corps insists that, while the old lock still works, it’s not at all efficient. Its limited width forces barge traffic to transit one at a time.

“When a tow goes through there with multiple barges, they have to take multiple cuts through the lock, which means more openings of the bridge, more closings of the roadway to street traffic,” Stark told The Lens. “With the larger lock, those are going to be reduced.”

Corps, industry groups say old lock slows shipping traffic

The Corps says it takes an average of more than 16 hours for each tow vessel to complete the passage, more than 15 hours of which is spent waiting for tows through the lock. And the Corps says the costs of maintaining and operating the lock have increased over the years.

The $951 million cost of the lock replacement would be split two ways, with half paid for by the Corps and half by the Inland Waterways Trust Fund, a U.S. government fund that is paid into by shipping companies that use the nation’s inland waterways.

“We strongly support an updated, modernized lock for the GIWW at the IHNC,” Stark told The Lens.

The last available report from the Corps’ Institute for Water Resources shows more than 15.3 million tons of cargo were transported up and down the Industrial Canal in 2017. That’s up from 10.7 million the previous year, but totals averaged between 15 and 16 million tons a year from 2013 to 2017.

“It’s been relatively flat lately,” Stark said. “I think part of that is because of the inefficiencies in using the lock. But I’ll tell you that the industries to the east greatly depend on what comes through there.”

The vast majority of that barge traffic carried petroleum and chemical products. The Canal Association and the Corps say they expect that traffic on the Gulf Intracoastal to increase in coming years. The Corps’ most likely economic growth forecasts suggest annual tonnages on the Industrial Canal could hit the 25 million mark by 2061.

Despite the industrial desire for a new lock — and its inclusion on a 2017 list of national infrastructure priorities, reportedly compiled by the Trump Administration and obtained by McClatchy Newspapers — there’s currently no funding dedicated to actually constructing it.

“We only have funding for evaluating it,” said Ricky Boyett, chief of public affairs for the Corps’ New Orleans District. “It’s a traditional civil work, so we would make our recommendation which the chief, if he concurs, would forward on. Congress would then have to approve our recommendation as well as fund it.”

Initial steps toward construction on a previously planned deep-draft lock were underway in August 2005, when Hurricane Katrina struck the city. But that construction was delayed when a federal court ruling in 2006 required the Corps to complete a Supplemental Environmental Impact Statement (SEIS) to consider the potential impacts of future hurricanes and flooding on such a project.

The deep-draft lock project was abandoned after another decision by the U.S. District Court in New Orleans — this one in 2011 — found that the Corps’ 2009 environmental impact statement failed to properly account for the post-Katrina closure of the Mississippi River Gulf Outlet (MRGO) to deep-draft commercial shipping and the impact that would have on shipping traffic. The Corps’ current study phase, which ends this December, is in response to that 2011 ruling and is focused on reanalyzing its earlier research on a lock replacement.

The lock that the Corps tentatively recommended in a 2017 draft report would be 900 feet long and 110 feet wide, allowing two barges to transit at a time. It would be 22 feet deep, which is less than the current 31.5 feet depth. It would be built between the Florida Avenue and Claiborne Avenue bridges.

Substantial dredging would be required to widen that stretch of the Industrial Canal, and it would require a huge “cofferdam,” or enclosure, around the construction site, a bypass channel for use by barges during construction, new floodwalls and demolition of the existing St. Claude bridge over the canal. The Corps first would build a temporary bridge at St. Claude during lock construction and later a permanent replacement.

“The traffic impacts are probably our most significant community impact and that we need to evaluate, and we’re still working on getting the best numbers we can,” Boyett said. “That is kind of the biggest factor we have to consider in terms of, not only is it storm evacuation, it’s emergency services and factors along those lines.”

Boyett confirmed that a temporary bridge would replace the St. Claude bridge and also cited possible improvements to the Florida Avenue Bridge to help better handle traffic. “That is one of the focal areas of this entire study, is understanding that traffic and how do you mitigate for it,” he said.

‘You’re making sitting ducks out of us’

Opponents of the replacement agree that traffic is a huge point of concern.

“Thirteen years of them not bringing the St. Claude bridge down, that’s a big impact on our community: Lower, Upper and Chalmette,” said Debra Campbell, an organizer with the resident advocacy group A Community Voice. “That’s our way for emergency units to get through. That’s our way for us to run away from storms, from hurricanes. So, you’re cutting us off and giving us just two maybe-will-work bridges and one we know is definitely not going to work for 13 years. Come on, why put us in that position? You’re making sitting ducks out of us.”

“Anybody who travels across those bridges is going to be impacted,” said John Koeferl, who works with the Holy Cross Neighborhood Association and is president of the group Citizens Against Widening of the Industrial Canal. “Anybody who has a business there or has to get their kids to school or go to the grocery store, any kind of commerce that people do in their own lives and as a job is going to be impacted.”

Residential evacuation ahead of severe tropical weather is a sensitive matter for many New Orleanians. One of the groups involved in discussions with the Corps, the Louisiana Landmark Society, raised the issue in a letter outlining its opposition to the project.

“The current location of the lock jeopardizes citizen’s safety as difficult choices are required to either open bridges for maritime vessels maneuvering to safety, or allow thousands of vehicles to evacuate the hurricane’s path,” wrote Sandra Stokes with the Landmark Society. “The bridges that must be crossed by thousands will still need to be opened to allow barges to move to safety with the new lock. The number of people who died due to difficulties evacuating during Hurricane Katrina is just one reason this must be part of the equation before heading down the 22-year-old pre-Katrina path.”

Stokes’ letter was written to Jason Emery, the Corps archaeologist who is working with state and local groups in compliance with Section 106 of the National Historic Preservation Act. That law requires all federal agencies such as the Corps to identify and assess the impacts that any project or other undertaking might have on historic properties. The Landmark Society, as well as A Community Voice and the Holy Cross Neighborhood Association, took part in a conference call with Emery Tuesday afternoon.

The letter by Stokes addressed a range of issues, including the removal of trees whose “root systems have grown integral to the lock structure” and the impact of noise from the construction vehicles that would continuously transit the area around the lock construction site. Stokes called for the Corps to conduct video documentation of area historic structures, inside and out, to use as a baseline for potential damage compensation to owners.

“We have a lot of struggling restaurants and small businesses” around the Industrial Canal, said A Community Voice director Beth Butler. “Wait until they are completely cut off with all this big heavy equipment and filthy conditions, and we’ll all have particulate matter in the air, and people [are] having all kinds of health problems as it is.”

Toxic material at the long-polluted Industrial Canal zone is a critical concern. The Corps recognizes a lengthy list of volatile, metal, petroleum hydrocarbon and other contaminants as well as pesticides and herbicides at the site. Corps officials said that much of the material dredged from the canal would not be suitable for open water disposal and would have to be placed in solid waste landfills.

Another issue Butler raised was the risk of increased flooding along the canal.

“This thing is like a plug or a dam for the whole Mississippi River and the force it has, coming down river,” Butler said. “They don’t even know how to demolish it.”

Boyett disputed that. “The lock is actually not the plug,” he said.

Rather, he said, the area is currently protected by flood walls, and even larger flood walls are planned. “As you push the lock towards the lake — the current recommended location is much further toward the lake area — you would have to build new walls that need the Mississippi River elevation height, which are greater than that of the hurricane reduction heights at that level.”

Boyett noted the substantial changes to the system protecting those neighborhoods around the canal from storm surge. He said the system before Hurricane Katrina used the flood walls lining the canal and the Gulf Intracoastal Waterway as first lines of defense. “But the first line of defense now is the surge barrier out in Lake Borgne, as well as Seabrook on Lake Pontchartrain,” he said.

‘You’re only as good as your last project’

Those new structures, parts of the Corps’ Hurricane & Storm Damage Risk Reduction System around greater New Orleans, were built after dozens of levees failed after Katrina in 2005, including those along the Industrial Canal. The GIWW and the MRGO effectively funneled surge waters into the city, causing severe flooding that left much of New Orleans submerged for weeks.

Many residents’ lingering distrust of the Corps is rooted in great part in that disaster and the failures of the old protection system; it is not dispelled by the huge scale of the new protection system, the largest civil works project in the Corps’ history.

Boyett told The Lens he understands that skepticism.

“You kind of have the old adage that you’re only as good as your last project,” he said. “And so, though I do understand their skepticism, working in an area such as this in terms of, really, into an urban center with not a lot of space — to do so, it would take a lot of planning before we ever launch into construction, the sequencing and the line out, in manners which minimize the impact. It would have to be down to the finest detail. And that’s what we would end up having to do.”

Part of that planning will go into the Corps’ Community Impact Mitigation Plan, or CIMP. That plan is designed to offset and/or compensate for impacts the lock replacement project would have on the surrounding communities, including the Upper and Lower Ninth Ward, Holy Cross and Bywater. A 1997 draft of the CIMP includes such programs as soundproofing residential structures, synchronizing traffic signals, community-based job training and an incident management plan.

But that plan has few details available at this point, and some opponents consider it badly outdated.

“This is 22-year-old material that assumes a static world and needs,” Stokes wrote in her letter to the Corps. “A new, open and transparent process of ‘broad-based community participation’ needs to be conducted, with new participants who represent the current population, to include consideration of the changing environment and needs. A new CIMP should be developed with current input and information.”

There’s also a big push by opponents to move the site of a replacement lock completely away from the Industrial Canal. Butler and others at A Community Voice suggest the Corps should build the new lock at the town of Violet, down the river in St. Bernard Parish.

“They have a canal,” she noted. “They just need to dig that way and make it bigger. I think the parish officials and the people of St. Bernard need to find out how they want to do it.”

Butler said some parish politicians have expressed an openness to discussing a new lock at Violet, whose canal connects to the MRGO. That could pave the way for substantial mitigation funding for the parish.

She cited an appearance at A Community Voice’s meeting in the Lower Ninth Ward Friday by St. Bernard Parish Councilman Gillis McCloskey. The group’s web site said McCloskey “pledged to work with A Community Voice to stop the Industrial Canal project.”

McCloskey has not responded to calls for comment, however, and The Lens has not confirmed any interest by the parish in hosting a new lock at Violet.

And Boyett from the Corps said the Violet option isn’t a good option because it could threaten wetlands in the area.

“The amount of environmental wetland impact would have been huge for us to go through that way,” he said.
