Where CoreSite is being opposed
- CoreSite DE3Denver, Colorado · Under construction · Contested
Elyria-Swansea residents have opposed the project over water use, air pollution and noise since construction began, holding a neighborhood press conference in February 2026; the backlash helped prompt Denver's one-year moratorium on new data center approvals, passed by city council in May 2026, which blocks CoreSite's two additional planned buildings but not the one already standing.
- CoreSite Hillsboro Data Campus (HI1/HI2)Hillsboro, Oregon · Proposed · Contested
Neighbouring property owners filed letters of concern over Oregon white oak removal via a fee-in-lieu buyout, wetland and greenway encroachment, and the 92-foot four-storey Phase 2 building.
