904 Francis Harris Lane — San Marcos Proposal

The listing describes 904 Francis Harris Lane as announced retail colocation in San Marcos at 0 MW, operator Unknown Company, with a 200-acre note next to Hays Energy. City and press records name the applicant. San Marcos’s development-projects page describes a nearly 200-acre Francis Harris Lane Data Center, land inside and outside city limits, a Preferred Scenario amendment from Conservation/Cluster to Commercial/Employment Low, rezoning from CD-2.5 / FD to Light Industrial, and annexation of about 64 acres. Landowners in earlier DCD coverage were Highlander SM One LLC and, separately, Donald and Germaine Tuff. Counsel Armbrust & Brown appeared for the applicant.

Capacity language is planned, not measured. January 2026 Statesman coverage of a Planning and Zoning recommendation described five buildings at about 76 MW each and a closed-loop fill of 60,000–70,000 gallons. That 76 MW figure is a proposed building power rating. It is not operating IT load and not an interconnection award the cited evidence can certify. The 18 February 2026 Statesman report said council then denied the preferred-scenario map 5–2. Status is a denied or stalled entitlement path, not construction. This proposal remains distinct from other Francis Harris Lane data-center proposals. The listing’s 0 MW baseline is empty, not a load study.
