Cassini Gateway I Data Center Campus

announced

Announced in 2017; no source fetched this session confirms construction, completion, or cancellation, so status remains 'announced' with an unresolved current-status gap. Sources conflict slightly on park size (3,000 vs 3,300 acres). Sherman's later semiconductor investment (Texas Instruments, GlobiTech/GlobalWafers, Coherent) is adjacent context, not part of this campus.
