Elon Musk’s Feedback on Houston Flood Tunnels Are Deceptive, Consultants Say

Billionaire Elon Musk is taking challenge with a recent investigation by the Houston Chronicle and The Texas Newsroom that raised questions on a flood tunnel challenge he’s pitching to handle Houston’s continual flooding woes. However consultants stated his response, which he didn’t clarify to the newsrooms, isn’t supported by info or information.

Final month, the newsrooms reported that Musk’s tunneling firm, The Boring Co., has been lobbying elected officers for months to permit it to construct tunnels underneath Houston for flood mitigation. Boring has proposed digging two 12-foot-wide tunnels beneath Buffalo Bayou — the principle waterway operating by central Houston — to hold stormwater out of neighborhoods and towards the Gulf of Mexico throughout main storms. Consultants say, nonetheless, that bigger tunnels, nearer to 30 to 40 toes in diameter, might carry much more water and be simpler.

Musk and representatives with Boring didn’t reply to interview requests or reply questions the newsrooms despatched prematurely of final month’s story about whether or not Boring’s smaller tunnels would be capable to deal with the dimensions of floodwater Houston is prone to encounter sooner or later.

As an alternative, Musk waited till hours after the story printed to put up a response on X, the social media firm he’s owned since 2022.

“Boring Firm tunnels will work and price <10% of options,” his Aug. 28 put up learn. “If extra stream is required, further tunnels will be constructed and moreover they are often route water from many elements of the town, not only one.”

The put up was written in response to a put up on X from U.S. Rep. Wesley Hunt, a Houston Republican who helped prepare non-public conferences with authorities officers in Harris County and throughout the state to promote them on Boring’s flood tunnel plan. Hunt additionally didn’t reply to questions from the newsrooms forward of publication of the unique story, however he weighed in on X after the story was printed.

“A lifelong Houstonian and Texas Congressman spoke to the neatest man on planet earth about fixing a generational flooding challenge in our metropolis that nobody else will repair,” Hunt wrote.

Musk’s put up supplied no information or engineering rationalization to again up his assertions. So the newsrooms examined his statements, evaluating them in opposition to flood research, and interviewed engineering consultants, a few of whom identified key technical and logistical challenges with the Boring plan.

One among Musk’s claims is probably going false, and the others should not but potential to confirm with certainty, in keeping with the newsrooms’ examination.

Once more, when the newsrooms pressed Musk and Boring representatives to clarify the tech billionaire’s claims, they didn’t reply. Nor did Hunt.

Would Boring’s tunnels price lower than 10% of options?

Musk’s proposal carries a lower cost tag than the estimated price of the bigger system the flood management district has spent years and thousands and thousands of {dollars} learning. However that’s partly as a result of the 2 are strikingly completely different proposals.

Hunt’s workforce has stated Boring’s Buffalo Bayou challenge would price $760 million, in keeping with inside communications obtained by the newsrooms by public information requests.

The county’s flood management district, then again, proposed in 2022 tunnels of 30 to 40 toes in diameter for that phase of the system at a worth of about $4.6 billion.

For the reason that challenge remains to be within the analysis section, the county numbers are preliminary. However primarily based on the figures accessible, Boring’s proposal would price nearer to one-sixth of the county’s estimate — not lower than 10%, as Musk’s put up steered. So Musk appears to be exaggerating how less expensive his system can be.

Flood management consultants additionally maintained that the decreased worth is considerably proportional to the decreased capability of Boring’s narrower tunnels. Two 12-foot tunnels would offer lower than one-fifth of the amount {that a} single 40-foot tunnel provides.

Which means they might divert much less water from susceptible areas than one massive tunnel.

Jim Blackburn, a Houston environmental lawyer and flood coverage skilled, stated whereas Musk’s firm deserves a good listening to, cheaper doesn’t robotically imply higher.

“If it’s a smaller tunnel, then I’d count on it to price much less,” Blackburn stated. “You’ve bought to have a look at how a lot flood mitigation you get for the {dollars} you spend.”

Emily Woodell, a spokesperson for the Harris County Flood Management District, stated the company wants extra data earlier than it may possibly weigh in on any of Musk’s claims.

“We’d should do a whole lot of examine earlier than something might even probably transfer ahead, so I wouldn’t need to speculate,” she stated. “Till we have now a challenge or one other examine, we’d level individuals to our web site for the studies and information we’ve compiled up to now.”

Can further tunnels be constructed for extra water stream?

Musk’s put up stated if extra floodwater must be moved, extra tunnels will be added. Engineers stated it’s not that straightforward.

Larry Dunbar, a veteran water assets engineer who has suggested Houston-area governmental businesses on drainage points, stated primarily based on dimension alone, it could take about 11 of Boring’s tunnels to hold the identical quantity of water as one massive tunnel. Lined up facet by facet, with sufficient room between them to maintain the bottom steady, the total system might span lots of of toes. That might require securing rights to extra land and constructing extra entry factors for upkeep, he stated.

And every new section of development would possibly convey one other spherical of critiques and mobilization prices, Dunbar stated, undercutting the pace and affordability that Boring has touted as key benefits of its proposal.

“The problems begin to simply get increasingly difficult,” Dunbar stated. “Not that it may possibly’t be performed, however simply to form of throw on the market — ‘Oh, if we’d like extra, we’ll simply do extra’ — properly, there’s much more to it than that.”

Harris County Commissioner Tom Ramsey, who has an engineering background, agreed. Extra tunnels would additionally imply extra tools to keep up, which might drive up long-term prices, Ramsey stated.

He added that the county would wish to resolve on the total plan on the outset so all system components like pumps, drains and outfalls will be designed correctly.

“It might not be easy to only add further tunnels later,” Ramsey stated.

John Blount, a former Harris County engineer who retired after greater than three a long time with the county, equally dismissed Musk’s suggestion that Boring might simply construct extra tunnels if the preliminary plan falls quick.

Whereas engaged on different infrastructure tasks, Blount stated, he has come throughout quite a lot of contractors able to constructing tunnels massive sufficient to deal with the job correctly the primary time.

“You don’t begin small and determine it out later,” he stated. “This complete idea of placing in 20% of what you must see if it’s sufficient makes zero sense.”

Can Boring’s tunnels transfer water from different elements of the town, and can the tunnels work?

Musk argued that Boring’s tunnels could possibly be utilized in completely different elements of the town, not simply alongside Buffalo Bayou.

Some native officers agreed that Musk’s tunnels would possibly truly work higher for smaller watersheds that don’t tackle as a lot water as Buffalo Bayou.

Ramsey stated he helps exploring smaller tunnels for areas like Searching and Halls bayous, which run by different elements of the town and likewise want assets to strengthen their flood safety. The county commissioner publicly known as for a better have a look at narrower tunnels throughout a commissioners court docket assembly in April, after Hunt had pitched him on Boring’s proposal in February.

“It’s one other instrument in our toolbox to assist mitigate flooding. And positively with what’s occurring within the Hill Nation,” Ramsey stated, referring to latest deadly floods in Central Texas, “and what continues to occur in Harris County, we’d like as many instruments as we are able to presumably get.”

Woodell, with the flood management district, advised the newsrooms in August that the company initially centered on large-diameter tunnels as a result of engineering research recognized them as the simplest possibility for a countywide system.

Nevertheless, she stated smaller tunnels could possibly be a viable resolution in sure areas. Since that concept had not been a spotlight of analysis, she added, extra examine can be wanted earlier than any such challenge might transfer ahead.

Colleen Gilbert, govt director of the Greens Bayou Coalition — a nonprofit that works to guard neighborhoods close to Greens Bayou, in northeast Houston — stated communities in her watershed are determined for aid as properly. They’d welcome the large storm tunnel as soon as proposed by Harris County, she stated, however even smaller tunnels can be higher than nothing.

“We’d be thrilled to have any and all potentialities checked out,” Gilbert stated. “If Congressman Hunt and The Boring Co. are this, we’re delighted to listen to it.”

Consultants and officers the newsrooms interviewed, nonetheless, nonetheless took challenge with Musk’s sweeping assertion that “Boring Firm tunnels will work” as a result of it doesn’t consider complexities of the challenge or that success largely depends upon what sort of system the county in the end desires.

In a two-page memo Boring despatched to Hunt’s workforce in February and that was circulated amongst native officers within the county, the corporate framed the pitch as an “revolutionary, cost-effective resolution” to Houston’s continual flooding.

“We’re assured in our means to execute this challenge efficiently,” wrote Jim Fitzgerald, Boring’s world head of enterprise growth.

However Dunbar stated the one strategy to consider Musk’s declare is to give attention to the aim of the stormwater tunnels.

If the aim is to construct as massive a challenge as potential for the bottom worth, Dunbar stated, Boring’s proposal would possibly match the invoice. But when the aim is to defend lives and property from one other Hurricane Harvey-level flooding occasion, he believes the smaller-scale challenge merely doesn’t measure up.

“You need to have some underlying purpose why you construct this tunnel, what you’re attempting to perform,” Dunbar stated. “And I’ve not heard that Elon has provided that reply.”

Rock Owens, retired Harris County lawyer for environmental affairs who represented businesses together with the flood management district, stated he has seen native officers repeatedly greenlighting large tasks that weren’t properly thought out and led to pricey authorized battles.

He pointed, as an illustration, to flood management points alongside White Oak Bayou in northwest Houston. In a prolonged authorized battle that started in 1999, about 400 owners within the space blamed the county for approving upstream growth with out satisfactory flood management, which they stated brought about repeated flooding of their properties.

The Texas Supreme Court docket in the end dominated in favor of the county in 2016. However Owens stated even unsuccessful lawsuits are pricey and the form of problem that would have uncovered the county to a considerable damages award.

Musk’s ethos of moving fast and worrying about penalties later, Owens stated, solely heightens the chance.

“That works high quality within the non-public sector, however not the general public sector,” he stated. “We’re not Mr. Musk’s private fortune; we’re trying on the livelihood and lifelong investments of people that reside right here.”
