Case Study · San Marcos, Texas

$1.5 billion blocked by water.

Highlander Real Estate Partners spent years pursuing a data center campus in San Marcos, Texas. The city voted 5-2 to reject the rezoning — twice. The Edwards Aquifer made the outcome inevitable from day one.

RealClear AI would have scored this site 28/100 before the first dollar of entitlement spend.

Highlander assembles ~200-acre site

Fort Worth-based Highlander Real Estate Partners acquires land at 904 Francis Harris Lane, San Marcos, TX. Proposed scope: $1.5 billion data center campus, requiring full rezoning from existing classification.

First Attempt

First filing fails — supermajority never achieved

The initial rezoning application cannot secure the supermajority required to overturn P&Z's recommendation of denial. The San Marcos City Charter requires 6 of 7 Council votes to override. The votes are not there.

August 2025

P&Z Commission recommends denial — second attempt

On the second run, the San Marcos Planning & Zoning Commission votes to deny the rezoning. Stated reasons: water resource constraints tied to the Edwards Aquifer and vulnerability of the ERCOT energy grid.

February 17, 2026

Hays County judge proposes building permit moratorium

One day before the City Council vote, the Hays County judge proposes a moratorium on building permits for large water users. The legislative environment hardens overnight. Any remaining Council support evaporates.

February 18, 2026

City Council votes 5-2 to reject rezoning

After hours of public testimony, Council confirms the P&Z denial. The $1.5 billion data center campus — two-plus years and significant entitlement costs in the making — is dead.

The Fatal Constraint

Edwards Aquifer

Data centers consume millions of gallons annually for cooling. San Marcos sits above a critical recharge zone for the Edwards Aquifer — sole drinking water source for 2 million Texans.

The Second Kill

ERCOT Grid Vulnerability

Data centers add massive, continuous load to the Texas power grid. Commissioners cited grid vulnerability as an independent basis for denial — even if the water problem could be engineered away.

The Political Wall

Supermajority Threshold

When P&Z recommends denial, San Marcos City Council requires 6 of 7 votes to override. The project failed this bar on the first attempt. Council voted 5-2 against on the second — not even close.

The Comparable Signal

$64B Blocked Nationally

Multiple data center moratoriums across Texas. Similar projects blocked in Austin, Round Rock, and Kyle before Highlander filed. The pattern was visible in public records before the first application.

“What if you could see a 28/100 before you spent two years and seven figures trying to rezone it?”

The 34-Second Verdict

What RealClear AI finds at 904 Francis Harris Lane.

Before a single filing fee is paid. Before a single attorney is engaged. Before a single planning commissioner hears the words “data center.”

Comparable Flag

$64B in data center projects blocked or delayed across Texas due to water scarcity concerns. San Marcos has denied all large water-use rezoning requests since 2024.

Legislative Risk — Day Before Filing

Hays County judge proposed building permit moratorium for large water users on February 17, 2026 — one day before the City Council vote.

Recommendation

EXTREME DENIAL RISK. Do not proceed without water mitigation plan, aquifer recharge study, and multi-year community engagement strategy.

The Pre-Flight Checklist

Five signals. All publicly available.

Every risk that sank this project existed in public records before the first filing. RealClear AI reads those records so your team doesn't have to.

Rezoning Required — Not By-Right

Zoning Reader

The 904 Francis Harris Lane site was not zoned for data center use. Every rezoning request in San Marcos requires a public hearing, P&Z review, and City Council vote — with a supermajority override threshold when P&Z recommends denial. The project had no path to approval without near-unanimous Council support.

Supermajority Vote Threshold Identified

Pathway Mapper

San Marcos City Charter requires 6 of 7 Council votes to override a P&Z denial recommendation. The Pathway Mapper would have flagged this immediately: any project with significant opposition faces an almost insurmountable bar. Highlander failed to reach this threshold on the first attempt and lost 5-2 on the second.

Edwards Aquifer Recharge Zone Flagged

Zoning Reader

The Edwards Aquifer Authority maintains public records on recharge zone designations. 904 Francis Harris Lane sits within a sensitive water resource area. Data centers require millions of gallons annually for cooling towers — a direct conflict with the aquifer's protected status that a standard RealClear analysis would place in the first paragraph of any feasibility report.

Organized Community Opposition — Hours of Testimony

Community Sentinel

The Community Sentinel monitors planning commission agendas across Texas. Multiple prior data center hearings in Central Texas showed the same pattern: organized opposition, environmental groups, extended public comment periods. San Marcos residents had mobilized against large industrial water users before this application was ever filed.

Texas-Wide Data Center Moratorium Pattern

Comparable Analyst

The Comparable Analyst tracks entitlement decisions across Texas. At the time of filing, multiple cities had implemented or proposed data center restrictions over water scarcity and ERCOT grid concerns. $64B in blocked projects nationally was not a surprise — it was the trend line. RealClear would have surfaced this as a key risk factor before day one.

Legislative Risk: Moratorium Proposed Day Before Vote

Community Sentinel

On February 17, 2026 — one day before the City Council vote — the Hays County judge proposed a building permit moratorium for large water users. RealClear's legislative monitoring would have flagged this emerging regulatory environment weeks earlier, giving the developer a final off-ramp before the public hearing.

The total cost of this entitlement failure:

Entitlement costs for large-scale rezoning range $50K–$260K in direct fees, attorney time, and consultant costs — before a single permit is issued. Add two-plus years of developer time, land carry costs on ~200 acres in the Texas Hill Country, and an opportunity cost measured in nine figures.

A 34-second RealClear analysis costs less than one hour of attorney time.
