SpaceX has quietly filed plans to park a gigantic semiconductor and advanced-computing campus at Gibbons Creek Reservoir in rural Grimes County, outlining $55 billion for initial phases and room to swell to as much as $119 billion. A public hearing is set for June 3, and residents around the Bryan-College Station area are already pressing local leaders to spell out what, exactly, is headed their way.
What the county filing says
The notice lays out a proposed "SpaceX Reinvestment Zone No. 1 - 2026-001" and describes a "multi-phase, next-generation, vertically integrated semiconductor manufacturing and advanced computing fabrication facility" that could qualify for property-tax abatement agreements under state law. The posting estimates $55 billion in capital for initial phases and up to $119 billion if additional stages are constructed, according to the Grimes County public notice.
Neighbors call for answers
People who live near the reservoir say they found out about the potential project from county postings and local word of mouth, and they want straight answers on water use, traffic impacts and the site's cleanup plan. "The only thing that we know is what we are sharing with each other," a local organizer told KWTX, as community groups push for a strong turnout at the June 3 hearing.
Where Terafab fits in Musk's chip push
Terafab first surfaced in March as a roughly $20 billion proposal centered on Austin, but the Grimes County filing shows the vision now stretches to additional, separate sites. Intel confirmed in April that it would join the Terafab effort, according to Reuters, and major industry toolmakers are already watching closely. ASML's CEO told Reuters he has spoken with Musk and called the project "very serious," a sign the plan is reverberating through the global chip supply chain.
Infrastructure and environmental questions
The proposed footprint sits on land that once hosted the Gibbons Creek coal-fired power station and reservoir, a parcel that was acquired and put through remediation processes in recent years, giving potential developers existing water and transmission assets to work with. Filings from Charah Solutions show the company took ownership and remediation responsibility for the Gibbons Creek site after the plant's retirement, and that history is now front and center in local development talks.
Large, leading-edge fabs typically use millions of gallons of ultra-pure water per day and require substantial, highly reliable power. Industry reporting and technical analyses underscore why residents and planners are pressing for detailed water-reclamation and grid-upgrade plans, including work highlighted by Semiconductor Engineering.
What the June 3 hearing will cover
The Grimes County Commissioners Court is set to consider formally designating the reinvestment zone and any tax-abatement agreement at its 9 a.m. meeting on June 3 at the county Justice & Business Center. Space Exploration Technologies Corp. is listed as the applicant in the filing, and county leaders say the process will include public comment.
The Houston Business Journal quoted County Judge Joe Fauth III saying, "the decisions that we make today, it can be a generational change for our county," as reported by KHOU/Houston Business Journal.
Why this matters
Signing off on any incentive package or reinvestment-zone designation would push a huge and complicated project into a new phase of permitting, planning and scrutiny. In the coming weeks, filings that spell out water sourcing, power arrangements and detailed environmental remediation will be the clearest signal of whether Musk's Terafab ambitions at Gibbons Creek are really headed toward the massive scale laid out in the county notice.
