Grid & water — why here
source: HIFLD · EPAThe closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.
