Status context. Operator-reported DE3 construction project. The current facility page says Coming Soon and the community page still forecasts late 2026 operation; the October 6, 2025 announcement reported construction topping off. Those sources support a construction project, not current operation, a confirmed opening day or completion of the wider three-building campus.
Approximate area, cited parcel/address context. Map area centered on Denver reference parcel 0214400131000 at the operator’s Race Street address, corroborated by Census address-range matching and Colorado air-application context. General-reference GIS, not surveyed property bounds, a verified building center or the full campus boundary.
Dated record.
