SDC San Marcos — Sabey Data Center Proposal

TYPE3’s map data lists SDC San Marcos under Sabey Data Center Properties LLC in San Marcos, with `Announced` status and 0 MW. Public reporting from 2025 describes Sabey seeking a development agreement for approximately 786 acres southwest of South Old Bastrop Highway and Centerpoint Road. The proposal included a mix of conservation, housing, and data-center development, with roughly 184 acres identified for light-industrial use and a Pedernales Electric Cooperative substation in the concept. Entering negotiations was not final approval.

San Marcos city materials also describe a separate Francis Harris Lane / Maberry data-center proposal and note that a separate Sabey site was under development-agreement review. Those nearby projects should not be merged: the city records use different applicants, tracts, and approval processes. The SDC San Marcos row has no supported building square footage, MW allocation, construction milestone, or customer evidence in the reviewed sources.

SDC San Marcos serves a high-intent Sabey/San Marcos query as an early-stage record. The 786-acre figure is proposed site context, not data-center building area. Its development agreement, parcel boundaries, land-use approvals, substation scope, water plan, and any current construction or tenant evidence still require confirmation before TYPE3’s map data baseline changes or commercial availability is described in the reviewed sources to date.
