Denver / 13-0 / 12-month / effective May 21

Denver is the cleanest 'yes' outcome of the four. Unanimous (13-0), one-year duration, immediate three-day window before effect (May 21), and the moratorium is scoped specifically to data center as the 'proposed primary use' — meaning a data center sub-component inside a mixed-use industrial site is technically not blocked, but a pure data center campus is. The working group framing is the operationally important piece: Denver did not commit to any specific regulatory framework after the year ends, so the period from May 2026 to May 2027 is open-ended on what the post-moratorium rules will look like. The CoreSite apology is the political tell — the existing Denver data center footprint (CoreSite + EdgeConneX + others in the Elyria-Swansea neighborhood) is the political base for the moratorium fight, not a forward-looking environmental concern. 'Existing facility impacts on adjacent residential neighborhoods' is now the dominant local political narrative for data center pause efforts in mountain west cities.
