Provider notes
Community. Covered by the same Oct 10, 2023 5-2 Board of Supervisors package vote as Carter's Store (case ST23-0031, 1.9M sq ft); the two dissenting supervisors objected to unwritten agreements, not the project itself.
What the source record says
329 acres in Massaponax, ~1.9M sq ft; one of four AWS Spotsylvania/Caroline campuses (Summit Crossing, Carter's Store, Cosner, Orrock). Spotsylvania case ST23-0031.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
