Opposition and litigation at this site

Partly. Both documented support and documented opposition to CloudHQ Manassas MCC Campus in Manassas, Prince William County, Virginia appear in the record, with no clear majority position. The campus opened in 2017 in a pre-designated data-center overlay zone away from the contested Manassas Battlefield corridor, and a 2025 proffer amendment for a new building was recommended for approval with no documented site-specific opposition.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: mixed reception means documented support and documented opposition both exist with no clear majority position on record.

The campus opened in 2017 in a pre-designated data-center overlay zone away from the contested Manassas Battlefield corridor, and a 2025 proffer amendment for a new building was recommended for approval with no documented site-specific opposition. But Prince William County is a national data-center flashpoint, the nearby 'Digital Gateway' rezoning was voided by the Virginia Court of Appeals in 2026 after community litigation. CloudHQ is eligible for Virginia's data-center sales-and-use tax exemption, but state law bars disclosure of recipients and amounts.

Power and water

Served via Dominion Energy's Clover Hill substation (300 MVA); a local distribution cooperative is reported to supply part of the campus. On-site backup is diesel only (28 generators at the first building).

The first building (MCC1) uses a waterless air-side design, 152 Kyoto Cooling heat-wheel units driving PUE below 1.2; cooling for later buildings is not confirmed. The campus is within the Prince William Water service area.

  • Permanent jobs promised
Which document closes each gap
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
