A Texas technology park proposal raises new questions near Castroville

Medina Technology Park draws notice

A quiet stretch near Castroville is suddenly part of a much bigger Texas tech conversation. The project’s official name is Medina Technology Park, a 265-acre site planned by Tract in Medina County, west of San Antonio.

The proposal is designed to support the fast-growing data center market near San Antonio. Tract lists the site’s energization target as mid-2028, and local reporting indicates the project could involve about 500 MW of electrical capacity.

Medina Technology Park raises questions

The Medina Technology Park plan is not just another business project to nearby residents. It would sit off County Road 4516 and U.S. Highway 90 W., not far from the Alsatian Golf Club and existing data center development.

Some residents worry the area could feel less rural as larger technology sites move in. Their concerns include water demand, power use, traffic, noise, emissions, and property values.

Medina Technology Park meets growth

The Medina Technology Park site is being described as part of the San Antonio data center market, not just a local Medina County project. Its location matters because San Antonio has become a major hub for cloud and digital infrastructure.

Tract says Medina Electric Cooperative and the East Medina County Special Utility District would serve the site. That utility connection is a key reason residents are watching the project closely.

The land size feels huge

A 265-acre development can sound abstract until people picture it next to homes, roads, and open land. For a small community, that much acreage can feel like a major shift in the local landscape.

The site would be large enough to stand out even before buildings rise. That is why the debate is about more than data storage. It is also about how much industrial-style development one rural area can absorb at once.

Power demand drives concern

Data centers need steady power because servers must run continuously. That is one reason a 500 MW capacity figure gets attention from residents and utility watchers.

Supporters may see major infrastructure as a sign of investment. Critics may ask whether nearby communities will face greater strain on power systems, higher costs, or challenges in future grid planning. The real question is how fast the region can grow without leaving residents feeling overlooked.

Fun fact: The U.S. Department of Energy said data centers used about 176 terawatt-hours of electricity in 2023, about 4.4% of total U.S. electricity use.

Water worries are personal

In Texas, water concerns can feel personal fast. When residents already worry about pressure, drought, wells, or utility capacity, a large technology park can raise hard questions.

Data centers vary widely in water use depending on cooling systems and design. Still, EESI notes that water use can vary widely by cooling design, but some large data centers can use up to 5 million gallons per day, roughly comparable to a town of 10,000 to 50,000 people.

Little-known fact: Some data centers use air cooling, while others use water-based cooling systems.

Microsoft is already nearby

The Tract site is planned next to an existing Microsoft campus in Castroville. That detail helps explain why residents see the project as part of a larger pattern, not a one-time proposal.

State filings describe a Microsoft data center project outside Castroville totaling about 489,400 square feet, which helps explain why residents see this area as part of a bigger buildout. With more technology projects underway in Medina County, residents are asking what the area’s long-term vision really is.

San Antonio’s pull is strong

San Antonio’s data center growth is helping push development into nearby counties. Land outside the city can accommodate large campuses, utility planning, and access to regional infrastructure.

That growth can bring construction work, tax value, and technology investment. It can also bring local pushback when residents feel the benefits and burdens are not evenly shared. Near Castroville, that tension is now part of the public conversation.

Residents want clear answers

Residents are not only reacting to one building plan. Many want direct answers about noise, water, power, traffic, fire safety, road wear, light, and long-term land use.

That is common when major infrastructure moves near homes and farms. People want to know what will happen before construction, during construction, and after the site is running. The more specific the answers, the easier it is for communities to judge the real impact.

Local control can be limited

Castroville’s mayor said the development is outside city limits, according to local reporting. That matters because it can limit what city officials can directly control.

When a project sits outside city boundaries, county officials, utility districts, state filings, and private developers may play larger roles for residents, which can make the process feel confusing. They may live near the impact but not always know which office has the final say.

Jobs are part of the pitch

Technology parks are often promoted as economic development. They can bring construction work, contracts, tax revenue, and long-term technical jobs.

Still, data centers do not always employ as many people as factories or warehouses of similar size. That is why residents may ask how many permanent jobs will actually come, what skills they require, and whether local workers will benefit. Economic growth feels different when the community can clearly see the payoff.

Timing gives room for review

Tract lists site energization for mid-2028, indicating this is not an overnight change. That timeline gives residents, officials, utilities, and the company time to discuss planning details.

The key is whether that time leads to better information. Communities often want environmental details, updates on utility capacity, road plans, emergency response coordination, and clear points of contact. Waiting without answers can make public concern grow instead of fade.

One proposal, bigger debate

The Medina Technology Park proposal is about more than one tract of land near Castroville. It reflects a bigger Texas question: how should fast digital growth fit into smaller communities?

Residents want reliable water, steady power, safe roads, and a voice in decisions that change their neighborhoods. Developers want sites ready for a data-heavy future. The next challenge is finding a path that treats both growth and local quality of life as serious priorities.
