Elon Musk’s tunneling firm, The Boring Company, is seeking involvement in Houston’s effort to address its long-standing flooding problems. Years after Hurricane Harvey caused widespread damage, officials continue to consider a $30 billion flood tunnel system intended to divert stormwater away from the city.
The Boring Company has been lobbying Harris County and state leaders for several months with a proposal to build two 12-foot-wide tunnels beneath Buffalo Bayou. This plan would be a less costly alternative to the original county concept, which called for much larger 40-foot-diameter tunnels designed to channel water all the way to the Gulf of Mexico (now referred to as the Gulf of America). However, some engineers have expressed concerns that Musk’s approach would not adequately address Houston’s flood risks.
According to reporting by the Texas Newsroom and the Houston Chronicle, The Boring Company requested 15 percent of an estimated $760 million project cost upfront. U.S. Rep. Wesley Hunt, a Republican from Houston who is considering a run for Senate, has voiced support for Musk’s proposal. Shortly after this lobbying effort began, Harris County commissioners agreed to study smaller-diameter tunnels—similar in scale to those suggested by The Boring Company.
The initial vision for Houston’s flood control involved an eight-line system spanning 130 miles at an estimated cost of $30 billion—a project currently under review by the Army Corps of Engineers with no construction yet underway. Research indicates that one 40-foot tunnel could transport up to 12,000 cubic feet of water per second while being placed between 40 and 140 feet underground depending on location. By comparison, two 12-foot tunnels as proposed by The Boring Company would need to be multiplied five times over just to reach equivalent capacity and would be installed much closer to ground level—between 15 and 30 feet deep.
Boring representatives describe their design as “flexible” and “innovative.” Some local officials are reportedly open to exploring smaller tunnels in specific areas rather than across the entire region. A recent white paper introduced the possibility of forming a public-private partnership that could see a private company like The Boring Company take on responsibilities such as designing, building, or even operating portions of any future system.
There are doubts about whether The Boring Company is suited for this kind of infrastructure work since it has not previously built major flood-control projects; its experience is primarily in transportation tunneling ventures. Critics have questioned whether Elon Musk should oversee what would be one of Houston’s most ambitious infrastructure projects since Hurricane Harvey. With other cities moving forward on large-scale resilience projects amid growing climate risks, pressure continues mounting on local authorities in Houston over which path—if any—they will choose: Musk’s scaled-back model or the more expensive plan put forth by federal engineers.
