MGD depending on cooling tech
The site sits on the Lake Weatherford watershed — the sole municipal water source for the City of Weatherford (firm yield ~4.7 MGD). A water-cooled hyperscale facility could demand up to 3× the entire city's daily use. The developer has not disclosed cooling technology, water source, tenant, or grid interconnect plan.
Same developer pattern as Fermi/Pantex — Black Mountain Power LLC is a developer founded in 2024, not an operator. They simultaneously built up this site and a $10B Fort Worth project. Their parent group holds gas turbine permits in Tarrant, Jack, and Somervell counties, some labeled "data center backup," others described as "power for sale." The Parker site is unincorporated — no county zoning, no permits required beyond the TCEQ air permit for 5 gas turbines.
What's at stake nearby — 443 single-family residential parcels valued at $182.6M in the immediate neighborhood. A $1.5B equine development planned within one mile already reported as jeopardized.

The ten questions to demand answers to at the town hall

  1. Who is the tenant? No operating company has been disclosed; Black Mountain is a developer only.
  2. What is the water source, and where are the permits? Trinity Aquifer wells, Lake Weatherford contract, or BRA pipeline?
  3. What is the cooling technology? The 30× range in water demand depends entirely on this answer.
  4. Is 75 MW the final design, or just the bridge phase? Hyperscale facilities typically run 200–500 MW at full build.
  5. How long will "bridge power" run before grid interconnect? ERCOT queue is 800+ projects deep — could be 1–3+ years of 24/7 gas operation.
  6. What is the wastewater plan — discharge volume, treatment, and into the watershed or elsewhere?
  7. How many permanent jobs vs. construction jobs? Hyperscale typically 30–60 permanent vs. 1,000+ construction (2–3 years).
  8. What is ESD 3's capacity for a major lithium battery, transformer, or hydrogen fire at this scale?
  9. What happens if the project pauses or fails mid-build — stranded site, partial infrastructure, who pays?
  10. What is the status of the $1.5B equine development already reported as jeopardized by this project?

This executive summary distills a 2-page data sheet and a 1-page comparison table that follow. The data sheet documents the site (parcels, ownership, taxes), the fiscal scenario, water/power/noise/light impact, and adjacent-property baseline. The comparison table places this project alongside the Fermi/Pantex announced megaproject and against representative operating Texas hyperscale facilities.

Acquisition timeline: Black Mountain Power LLC assembled the 2,082-acre site through purchases from prior landowners during 2025–2026. First parcel transfer was the 172.8-acre core tract (R000041082) from Black Mountain Land Company LP on June 3, 2025. The remaining ~1,900 acres were acquired from the prior Knox family interests (Knox Jack Dill, Knox Ranch LLC) and Helm No. 1 Family LP through subsequent transfers concluded during 2025–2026. The Parker CAD ownership records lag the transfer dates; the current single-owner status is confirmed by Black Mountain's own statements and the Parker CAD's May 15, 2026 ag-strip notice issued to Black Mountain Power LLC.

Fiscal scenario — no abatement (per Parker County commitment)

Ag exemption stripped Nov 2025 — the 2,082 acres now generate ~$900K/yr on full market value (vs. ~$2,000/yr previously). One-time $2M ag rollback being collected. Once improvements begin, full market + improvement value becomes taxable; FSP absorbs most ISD M&O, all other entities retain full share.

Water risk (critical)

Site sits on the Lake Weatherford watershed — sole municipal source for the City of Weatherford. Demand at 75 MW depends entirely on cooling technology.

Cooling tech (75 MW)Million gal/dayvs. City of Weatherford daily use (~4.8 MGD)
Air-cooled (high-efficiency)0.2–0.55–10% of City
Closed-loop evaporative1.4–4.330–90% of City
Water-cooled (open evaporative)7.2–14.4150–300% of entire City use
City of Weatherford municipal demand~4.8Lake Weatherford firm yield ~5,300 ac-ft/yr

Power model — Fermi/Pantex pattern

5 simple-cycle gas turbines (15 MW each = 75 MW total). TCEQ permit framed "backup/bridge power" — Black Mountain's parent group holds turbine permits in Tarrant, Jack, Somervell counties (some explicitly "power for sale"). Bridge could last 1–3 years given ERCOT queue is 800+ deep.

5 × 15 MW gas turbines @ 80% capacityAnnual
Natural gas consumption5.5 Bcf (~$20M/yr at $4/Mcf)
CO₂ emissions~322,000 tons (≈ 70,000 cars)
NOx — with SCR (low) / without SCR (high)~33 tons / ~275 tons
Net power output @ 80% CF~525 GWh/yr (75 MW continuous)

Questions for the town hall

  1. Who is the tenant? Black Mountain Power is a developer, not an operator. Fermi/Pantex precedent: undisclosed-tenant hyperscale.
  2. Water source? Lake Weatherford contract, Trinity Aquifer wells (Upper Trinity GCD), or BRA pipeline?
  3. Cooling technology? The 30× range in water demand depends on this answer.
  4. Is 75 MW design or just Phase 1? Hyperscale facilities typically run 200–500 MW.
  5. "Bridge power" duration? 1–3+ years of 24/7 gas operation until ERCOT — that's the actual emissions period.
  6. Wastewater discharge — where, treated how?
  7. Permanent jobs vs. construction phase? 30–60 permanent typical; 1,000+ for 2–3 yrs construction.
  8. ESD 3 capacity for a major lithium battery / transformer / hydrogen fire?
  9. What if the project pauses or fails mid-build?
  10. The $1.5B equine development next door — what's its status?

Detail supporting the headline data sheet

A. Adjacent parcel value impact — baseline

443 residential parcels in immediate survey/abstract neighborhood. Industry research on DC proximity: -5% to -15% within 1 mile. Track 3–5 yrs for actual impact.

Neighborhood (same survey/abstract)ParcelsAvg valueTotal at risk
Residential single-family (A1)443$412,210$182.6M
Improved rural (E1)3$222,213$0.7M
Commercial/industrial (F1)1$665,820$0.7M
Total adjacent value (2024 baseline)447$184.0M

At -5% impact: $9.2M value loss. At -15%: $27.6M. Plus $1.5B equine development already reported jeopardized.

B. Air emissions — 5 simple-cycle natural gas turbines, 75 MW

Parker is in DFW 8-hour ozone non-attainment. NOx is a precursor. Two BACT scenarios bracket the realistic range.

Annual pollutantWith SCR (low)No SCR (high)Context
NOx (tons)~33~275PSD major source threshold: 250 tons/yr
CO (tons)~66~66NSR minor threshold: 100 tons/yr
CO₂ (tons)~322,000~322,000≈ 70,000 cars/year
PM2.5 (tons)~14~28Respiratory health impact
VOC (tons)~7~7Ozone precursor

80% capacity factor (continuous "bridge"), 10,500 BTU/kWh heat rate. Permit BACT determines which column applies.

C. Watershed — Lake Weatherford specifics

Lake WeatherfordValue
Conservation pool storage / firm yield19,470 ac-ft / ~5,300 ac-ft/yr ≈ 4.7 MGD
Surface area / drainage1,158 acres / 110 sq mi
Owner / right holder / backup sourceCity of Weatherford / Lake Worth (Fort Worth Water) purchases
Groundwater jurisdictionUpper Trinity Groundwater Conservation District

Three water-source scenarios: (1) Trinity Aquifer wells — Upper Trinity GCD permits; 14 MGD = 15,700 ac-ft/yr (unprecedented vs. typical 100–1,000 ac-ft). (2) Surface intake from Lake Weatherford — City declined to host the project; water sale agreement politically difficult. (3) Brazos River Authority pipeline — doesn't compete with municipal supply but expensive and slow.

D. Noise — 5 gas turbines + cooling equipment

Parker County has no noise ordinance for unincorporated areas. -6 dB per doubling of distance.

SourceAt 100 ftAt 1/4 mileAt 1 mile
Gas turbine (with enclosure)85 dBA61 dBA49 dBA
Cooling fans (large array)80 dBA56 dBA44 dBA
Transformers (substation)70 dBA46 dBA34 dBA
Combined facility (low-freq hum)90 dBA66 dBA54 dBA
EPA "quiet rural" night ambient35–4035–40

WHO night noise guideline for sleep disturbance: 45 dBA outside bedroom window. Low-frequency hum penetrates walls more readily. Audible 1.5+ miles in quiet rural conditions.

E. Light pollution — 24/7 operations

Parker County area is Bortle Class 4. No outdoor lighting ordinance in unincorporated Parker.

ImpactDistance affectedEffect
Direct light trespass0.5–1 mileLighting visible from residential windows
Sky glow dome3–7 milesOrange-white sky dome under clear conditions
Bortle scale degradation2 milesClass 4 → 5; Milky Way no longer easily visible
Wildlife disruption1–2 milesMigratory bird disorientation, nocturnal foraging
Construction phase (24/7)2–3 yearsMore intense than ops; aircraft warning + crane lighting

F. Action items

  1. TCEQ permit number / classification — determines SCR requirement and NOx ceiling. DFW 8-hr ozone nonattainment matters.
  2. Water source disclosure with permitting documentation — Upper Trinity GCD, City of Weatherford, or BRA.
  3. Development agreement with Parker County: water restrictions, hours, noise/light mitigation, road bonds, decommissioning bond.
  4. Petition for County noise + lighting ordinances (TX Local Government Code Ch. 240).
  5. Independent third-party water study — paid by developer, scope set by County.
  6. Get BRA + Upper Trinity GCD on the record about their permitting positions before well drilling.
  7. Document baseline now — 443 homes, $182.6M. Track 3–5 years for actual impact.

What the comparison shows

1. Disclosure profile is closest to Fermi/Pantex, not to operating facilities. Both are speculative builds where the developer is not the operator. Fermi has a state-level university partner that adds some public accountability; Pearson Ranch has only Parker County and private LLCs, with no formal disclosure obligation in an unincorporated area.

2. Self-generation by gas is the defining pattern of the speculative tier. Both Pearson Ranch (75 MW on-site gas) and Fermi (combined-cycle gas early phases) bypass the 5–7 year ERCOT queue by self-generating. Operating facilities use ERCOT and don't run on-site fossil generation. "Bridge power" means continuous 24/7 gas operation while waiting for grid interconnect — can last years.

3. Water risk is the same pattern as Fermi/Pantex — hyperscale demand on a stressed source. Fermi targets the Ogallala (already in long-term decline). Pearson Ranch targets the Lake Weatherford watershed and/or Trinity Aquifer (smaller, more sensitive, sole municipal source). Operating facilities use city water systems with built-in capacity agreements; speculative-tier facilities don't have those agreements, which is why water is the central question for Parker residents.

Questions Pearson Ranch must answer that operating facilities already have

  1. Who is the tenant, and what is the lease term and break clause?
  2. What is the water source, with permits in hand or under formal review?
  3. What is the ERCOT interconnection queue position and planned grid-connect date?
  4. What is the cooling technology specification?
  5. What is the IT load at full build (not just gas bridge)?
  6. What is the community benefit / development agreement with Parker County?
  7. What is the decommissioning plan and bond if the project pauses or fails?
  8. What is the air emissions BACT level and TCEQ permit type?

An operating Texas hyperscale (Switch, Digital Realty, Apple Round Rock) has documented answers to all eight before construction begins. Speculative-tier proposals (Pearson Ranch, Fermi Phase 1) have none of them.

Glossary and value calculation formulas

Foundation School Program (FSP) — the K-12 equalization mechanism

Texas's state-mandated K-12 finance system. Every ISD has a state-guaranteed per-student "entitlement." Local M&O property tax revenue is offset against that guarantee dollar-for-dollar: Net state aid = max(0, Entitlement − Local M&O revenue) Districts that raise more than their entitlement allows pay recapture to the state for redistribution to property-poor districts. Weatherford ISD is in or near recapture. Consequence for the data center: $8.5M in new M&O taxes per $1B improvement does not grow the ISD budget — it reduces state aid (or pays recapture). Only the I&S debt-service portion (~$2.4M on same $1B) is retained. All non-ISD taxing entities (County, College, Hospital, ESD, LR) have no equalization — they retain 100% of new revenue.

Value calculation formulas

Fiscal

Tax_entity = Improvement Value × Rate_entity ÷ 100
Rate per $100 taxable value. Example: $1B × $0.26/$100 (Parker County) = $2.6M annual. Sum across ISD M&O, ISD I&S, County, College, Hospital, ESD, LR for total gross.
Net ISD revenue = ISD I&S + max(0, ISD M&O − FSP offset)
FSP offset = state aid reduction or recapture from the new M&O. For property-wealthy districts like Weatherford ISD, the offset absorbs most of the M&O. I&S debt-service taxes are not subject to FSP equalization.
Ag rollback = Σ over 5 prior years of (Market_value_tax − Ag_use_tax)
Texas Tax Code §23.55. One-time recapture when ag-exempt land converts to non-agricultural use. Our case: ~$2M total across all entities.

Water

Daily water (MGD) = MW × 24 × CF × WUE × 264.17 × 10⁻⁶
WUE = Water Usage Effectiveness (L/kWh). Air-cooled 0.05–0.15; closed-loop evaporative 0.3–1.0; open evaporative 1.5–3.0. CF = capacity factor (typ. 0.8 for "bridge"). 264.17 converts L→gallons; 10⁻⁶ converts to millions.
% municipal supply = Facility_MGD ÷ City_MGD × 100
City of Weatherford daily use ≈ 4.8 MGD. Lake Weatherford firm yield ≈ 4.7 MGD. Demand >50% implies likely groundwater pumping or BRA pipeline as primary source.

Air emissions — natural gas turbines

Fuel (MMBtu/yr) = MW × 8760 × CF × Heat_Rate (BTU/kWh) × 10⁻³
Heat rate: simple-cycle ≈ 10,500 BTU/kWh; combined-cycle ≈ 7,000. Example: 75 MW × 8760 × 0.8 × 10,500 × 10⁻³ ≈ 5.5M MMBtu (= 5.5 Bcf gas).
NOx (tons/yr) = Fuel × EF_NOx ÷ 2000  ·  CO₂ (tons/yr) = Fuel × 117 ÷ 2000
EF_NOx with SCR ≈ 0.012 lb/MMBtu (~33 tons/yr); without ≈ 0.10 lb/MMBtu (~275 tons/yr). PSD major source threshold = 250 tons/yr. CO₂ factor 117 lb/MMBtu for pipeline natural gas. EPA AP-42 Ch. 3.1.

Noise & property impact

Lp(d) = Lp(d₀) − 20 × log₁₀(d ÷ d₀)  ·  L_total = 10 × log₁₀(Σ 10^(L_i÷10))
Sound pressure (dBA) at distance d from a point source: approximately −6 dB per doubling of distance. Multiple sources combine logarithmically (ISO 9613-2).
Adjacent value at risk = Σ(parcel_market_value) × impact_factor
Impact factor from peer-reviewed proximity studies (Loudoun VA, Hillsboro OR): −5% to −15% within 1 mile. Pearson Ranch baseline: 443 residential × $412,210 avg = $182.6M.
