Tesla has filed new site plans with Travis County detailing a significant expansion of its Giga Texas campus, including the long-promised “ecological paradise” along the Colorado River and infrastructure for the recently announced Terafab North Campus.
The filings, which include a permit application for “Tesla North Campus” submitted to the Travis County Fire Marshal on March 13, reveal the scope of Tesla’s ambitions for a campus that already stretches across 2,500 acres in southeast Austin.
The ‘ecological paradise’ — six years and counting
The centerpiece of the Travis County filing is Tesla’s GFTX Riverfront Eco-Park, an ambitious public green space project that CEO Elon Musk first promised during a July 2020 earnings call when he described the area as a future “ecological paradise” with “birds in the trees, butterflies, fish in the stream.”
According to Tesla’s 2024 annual report to Travis County, a requirement of the company’s Chapter 381 Economic Development Performance Agreement, the eco-park plans include 25 miles of walking trails, 18 miles of biking paths, and 3.78 miles of direct Colorado River access. The plans call for 290 acres of preserved waterfront green space, 53 areas of expanded wetland for flood mitigation, eight wildlife corridors, and a 14.5-mile onsite bioswale.

Tesla says it will plant 3,000 trees annually and build a sports complex with soccer, baseball, basketball, and tennis facilities. Additional amenities include a riverfront boardwalk, fishing zones, a children’s playground, and a community orchard. The company estimates 20,000 households will benefit from the park.
The problem is that Tesla has been talking about this project for nearly six years with very little to show for it. When we first covered Musk’s ecological paradise promise in 2020, the language was identical, grand vision, no timeline. In October 2023, Tesla presented a 120-acre pilot project to the Travis County Commissioners Court, claiming it had seeded 46 acres. Then, in 2024, Tesla used a new Texas law to exempt itself from Austin’s environmental regulations, the same water quality and flood mitigation rules that would apply to a project like this.
The latest filing still includes no completion timeline.

Terafab North Campus: 5.2 million square feet of expansion
The site plans also encompass the North Campus expansion tied to Tesla’s recently announced Terafab project — a joint $20-25 billion semiconductor fabrication venture between Tesla, SpaceX, and xAI that Musk unveiled on March 21.
Permit documents indicate Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas campus. The initial phase calls for a 2-million-square-foot research-and-development facility adjacent to the existing gigafactory, with the full-scale development eventually requiring “thousands of acres.”
Construction activity is already visible north of the existing facility, with ground clearing, soil reclamation, and infill operations underway, consistent with the early stages of a major foundation pour. Tesla has posted multiple Terafab job listings with Austin as the primary location.
The Terafab facility targets 2-nanometer chip production starting in 2027, with an initial capacity of 100,000 wafer starts per month and ambitions to scale to 1 million per month at full capacity. As we noted in our coverage of the Terafab announcement, Tesla has zero semiconductor manufacturing experience and is proposing to build the largest 2nm fab ever constructed — a claim that deserves significant scrutiny given the company’s history of overpromising on manufacturing timelines.
Also, EUV machines used in chip making are back-ordered through 2027.
Electrek’s Take
Giga Texas is impressive by any metric, but it has yet to deliver on its “ecological paradise,” and as we have made clear in the past, the Terafab plans feel like Musk’s desperate attempt to attach Tesla and SpaceX to the AI hyperscaler narrative.
The “ecological paradise” is a six-year-old promise that still has no completion date. Tesla exempted itself from Austin’s environmental oversight in 2024, which is a strange move for a company supposedly committed to building the region’s largest public ecological park along the Colorado River. The 46 acres seeded in 2023 represent a fraction of the 290-acre vision, and there’s no public evidence of significant construction on the eco-park since.
We’re not saying it will never happen, but the gap between Tesla’s site plan renderings and actual delivery — on the ecological paradise, on the 4680 battery cells, and now on the proposed Terafab — should make anyone cautious about treating these filings as anything more than aspirational. Travis County officials should be pressing Tesla for binding milestones, not just accepting another round of beautiful plans with no deadlines.
But I don’t see that happening. Like Tesla shareholders, they are focused on the Terafab dream.
