A separate Skybox project in Hutto must not be conflated with the Round Rock PUD
Key data: Hutto project is 159 acres at U.S. 79 and CR 132 under Hutto Data Center LLC, with Oncor purchasing 62 acres and Bob Farley as Hutto economic development director
Limitation: Same county and same developer, different city, case and site; keep as separate database records
The PUD caps the project at 75 MW of grid-interconnected power; Oncor must confirm capacity exists and the operator must sign a binding take-and-pay contract before proceeding. Grid capacity determinations rest with Oncor and ERCOT, not the City.
Key data: Cap of 75 MW grid-interconnected power
Status date: 2026 (page current)
Limitation: No ERCOT queue position/status disclosed for this load.
Council approved the rezoning after residents packed City Hall; opposition organized at protectroundrock.org and via a Change.org petition, and Public Citizen called the unanimous approval "a stunning betrayal of the public trust." Planning & Zoning had recommended approval 7-0 on Nov 5, 2025 with no public speakers at that hearing; the council hearings then drew over an hour of comment on water, low-frequency noise, air, and grid concerns.
Key data: P&Z 7-0 recommendation (2025-11-05); Council approved unanimously; organized opposition site + petition
Status date: 2025-11-05 (P&Z) / council vote thereafter
Limitation: Exact council vote date/tally not captured in the fetched city record; no litigation found. (confidence detail: VERIFIED_PRIMARY (city record) + DISCOVERY_LEAD (advocacy))

The City's own comparison: an existing data center pays roughly **$800,000/year** in city property tax while using about the water of 15 homes, versus ~$21,000 in city property tax from 15 homes at current median taxable value.
Key data: ~$800,000/yr city property tax vs ~$21,000 for 15 homes
Status date: 2026 (page current)
Limitation: City framing, not an independent fiscal-impact study; no abatement disclosed for Skybox.
No variance was sought: noise must comply with the City Noise Ordinance on the same terms as neighboring industrial users, and mitigation is structural — an 80-foot setback, 25-foot landscape buffer, and masonry compatibility wall toward the Chandler Creek MUD neighborhood. Traffic is limited to a maximum of three driveways on Old Settlers Blvd with no connection to Chandler View Trail; **no traffic study requirement is stated**. Neighborhood-meeting concerns included audible and low-frequency noise and generator testing frequency.
Key data: 80-ft setback, 25-ft buffer, masonry wall; max 3 driveways; no decibel limit and no traffic study in the record
Status date: 2025-11-05
Limitation: No predicted operational dB levels, no low-frequency limit, no monitoring requirement in the record.
