Published: 2026-03-29

Contour, TeraWatt, and THO propose converting St. Louis's historic Midtown Armory into a $3.1 billion, 487,000-square-foot, 120-megawatt data center campus. A 5-hour CUP hearing. A moratorium that failed 7-8. New city zoning rules being written simultaneously. Outcome genuinely uncertain as of March 2026.

Cited case read: 50/100 — a genuine coin flip, with multiple independent risk layers compounding simultaneously.

Midtown St. Louis, Missouri · 2026 · Ongoing

Three independent risk layers. All active simultaneously.

2025

Contour + TeraWatt + THO announce $3.1B Armory campus

A joint venture of Contour, TeraWatt Infrastructure, and THO (Third Home Office) announces plans to convert the historic Midtown St. Louis Armory and adjacent Former Famous-Barr warehouse into a 487,000-square-foot, 120-megawatt data center campus. Total investment: $3.1 billion. The scale makes it one of the largest proposed urban data center developments in the Midwest.

March 2026

5-hour CUP hearing — Board of Aldermen divided

A 5-hour conditional use permit hearing before the St. Louis City Board of Aldermen reveals a divided body. Supporters cite economic development and adaptive reuse of a historic building. Opponents raise noise and power grid concerns, neighborhood character, and questions about whether a 120 MW data center is the appropriate use for the Armory district. No decision is reached at the hearing.

March 2026

Moratorium vote fails 7-8 — razor-thin margin

The Board of Aldermen votes on a proposed moratorium on data center development while new zoning rules are drafted. The moratorium fails 7-8 — one vote away from passage. A single alderman shifting position would have frozen the project entirely. The razor-thin margin signals that the project's political environment is profoundly unstable.

March 2026 — ONGOING

New city zoning rules drafted simultaneously — historic review active

While the CUP is pending, St. Louis city planners are simultaneously drafting new data center zoning regulations that could impose additional requirements or restrictions on projects like this one. The historic Armory and Famous-Barr warehouse also face independent historic preservation review. Three separate regulatory processes — CUP, new zoning rules, and historic review — are running simultaneously with no coordinated outcome.

The CUP Risk

Full Discretion — No By-Right Path

A 120 MW data center in a mixed-use urban district requires a conditional use permit — full Board of Aldermen discretion. Unlike by-right development, no objective standard governs the decision. The 5-hour hearing without a decision signals that the board is genuinely uncertain. CUP outcomes in politically divided urban boards are among the hardest to predict.

The Moratorium Threat

7-8: One Vote from Frozen

A moratorium vote that fails 7-8 is not a victory — it is a warning. The project is one vote change, one alderman retirement, or one council election away from a complete development freeze. The moratorium advocates have not disappeared; they are waiting for the next procedural opportunity to press their case.

The Historic Risk

Famous-Barr + Armory District

The site includes the former Famous-Barr warehouse and the historic Armory — two buildings with independent historic significance. Adaptive reuse of historic structures for data centers requires demonstrating compatibility with the building's historic character. St. Louis's Cultural Resources Office review adds an independent approval layer that the CUP process does not resolve.

The Simultaneous Zoning Rewrite

New Rules Drafted While CUP Pending

The most dangerous risk for this project is not the CUP hearing — it is the new zoning rules being drafted simultaneously. If St. Louis adopts data center regulations that impose new requirements before the CUP is decided, the application must be reevaluated under the new rules. A project that was pending approval can become non-compliant overnight when the code changes.

Documented Record

The $3.1 billion project faces concurrent regulatory actions: a CUP requirement, a citywide data center moratorium under consideration, historic preservation review of the Armory building, and a comprehensive zoning code rewrite affecting the project site.

The Pre-Flight Checklist

Five source-record factors. All publicly available.

Every risk layer compressing this project's timeline was visible before the first dollar was committed. RealClear reads those records so your team doesn't have to.

CUP Required — Full Board of Aldermen Discretion

Zoning review

The Zoning review identifies that a 120 MW data center in St. Louis's Midtown district requires a conditional use permit — not by-right approval. St. Louis City Zoning Code §26.56 routes all large-scale technology facilities through the full CUP process, requiring Board of Aldermen approval. In a politically divided 28-member board, CUP approval requires assembling a majority with no guarantee of the outcome.

Moratorium Risk — Data Center Policy Climate in St. Louis

Community risk review

The Community risk review monitors proposed ordinances and legislative activity. St. Louis aldermen had been publicly discussing data center zoning restrictions for months before the moratorium vote. The 7-8 margin was not a surprise to anyone monitoring Board of Aldermen committee activity — it was the predicted outcome given the public voting record of each alderman.

Historic Preservation — Two Independent Review Processes

Zoning review

The Zoning review cross-references historic district boundaries and Cultural Resources Office review requirements. The Famous-Barr warehouse and Armory buildings both trigger independent historic review processes under St. Louis's Cultural Resources review framework — separate from the CUP process. Historic review can impose design constraints that change the economics of data center conversion fundamentally.

120 MW Power Draw — Grid Capacity Analysis

Zoning review

The Zoning review extracts the grid connection requirements for a 120 MW data center and flags the utility coordination requirements. Ameren Missouri's existing infrastructure in Midtown St. Louis was not designed to support a 120 MW load addition at this location. Grid capacity analysis is an independent approval layer that can add 18-36 months of utility engineering and upgrade work.

Simultaneous Zoning Rewrite — Legislative Race Against CUP

Community risk review

The Community risk review tracks proposed ordinances and code changes. New data center zoning rules being drafted while a CUP is pending create a legislative race: if the new rules are adopted before the CUP is decided, the application may need to be re-evaluated under the new standards. This kind of simultaneous legislative-administrative conflict is among the highest-risk scenarios in urban entitlement.

The unique danger of a 50/100 project:

A 50/100 score is not a moderate risk — it is maximum uncertainty. Every dollar committed on a coin-flip project is at full risk. A 2/100 project kills you quickly. A 50/100 project kills you slowly, after you've committed more capital and more time believing the tide is about to turn. This is the most expensive kind of entitlement risk.

A RealClear analysis gives you the 50/100 score before you write the check.
