01 · EXECUTIVE ASSESSMENT
HB-KILO-SA · REV 3.2 · 2026.09.16

Proceed to scoped tenant diligence.

The next decision is whether to align requirements and define the evidence needed for a later commitment.

The retained source analysis reports a 3,979.63-acre title-survey tract and executed LCRA study and PEC facility-extension agreements associated with a requested 2,100 MW load at 345 kV. These records support a site-specific diligence conversation.

Evidence supporting further review

Recorded deed and survey; study/development agreements; a scoped Phase I environmental assessment; preliminary substation and generation planning.

Conditions controlling delivery

Firm power availability, electric-energy supply, sustainable water, binding fuel terms, resilient connectivity and a tenant ready-for-service date remain to be established.

Preparation basis: this assessment summarizes retained Kilo source analysis and recorded references. Original-document verification is outside this edition’s preparation basis. Confirm cited records against current originals before a commercial commitment.

03 · CAMPUS CONTEXT
HB-KILO-SA · REV 3.2 · 2026.09.16

Source imagery locates the campus concept.

The title survey and an engineered master plan must establish the development boundary and usable layout.

Kerr County aerial context showing the source ranch outline and conceptual campus planning area
Source ranch outline and conceptual campus zones over aerial imagery; terrain shown at 2× relief. Planning context, not a survey, grading design or approved campus layout.

What the view can support

A shared geographic starting point for discussions of hall placement, access and utility corridors. Displayed planning zones do not establish buildable acreage.

What must govern design

Reconcile the survey, parcel record, environmental scope and concept geometry; then develop an engineered phased master plan for grading, drainage, access and utilities.

The image’s outlines and overlays retain their source meanings. No additional hazard legend, scale, acquisition date or approved route is inferred.

The deed and survey support a tract-level planning basis.

Current title diligence and parcel reconciliation remain open.

The source record describes a recorded special warranty deed to Blue Fox Development, LLC. Kerr County Document 24-02602 was recorded on 8 May 2024.

05 · ACCESS AND BUILDABILITY
HB-KILO-SA · REV 3.2 · 2026.09.16

Recorded access and slope screening support preliminary layout.

Screened acreage does not establish engineered pads or net developable area.

Recorded access

The source describes a 60 ft-wide, 16.33-acre YO Ranch Road strip and a 60 ft private-access easement in the title survey.

Slope-screening outputs

3,514.1 ac below 10% slope
3,109.4 ac below 5% slope
The source screens account for mapped FEMA and wetland areas.

Design questionRequired outputDecision informed
Can construction reach the site?Reconcile legal and physical access; validate heavy-haul, traffic, emergency circulation and road approvals.Construction-logistics assumptions and access rights.
Where can the campus be built?Engineered, phased master plan integrating grading, drainage, stormwater, roads, halls and utility corridors.Hall placement, buildable area and enabling-work scope.

06 · ENVIRONMENT AND GROUND CONDITIONS
HB-KILO-SA · REV 3.2 · 2026.09.16

The Phase I result is bounded to its stated scope.

The reported contamination screen does not establish comprehensive environmental clearance.

The source describes a January 2026 ASTM E1527-21 Phase I environmental site assessment reporting no recognized environmental conditions across approximately 4,005.86 acres and 24 parcels.

Investigation groupRequired planning response
Geotechnical and karstThe prospecting report describes predominantly Edwards Limestone Formation. Targeted investigations are required for halls, power facilities, roads, substations and corridors.
Wetlands, waters, flood and drainageComplete field and parcel-specific investigations; incorporate findings into grading, stormwater and utility design.

Proposed interconnections and preliminary design need reconciliation.

The current record identifies engineering inputs; it does not evidence issued design or secured route rights.

Proposed interconnections

Two proposed points of interconnection (POIs) on LCRA-owned Big Hill–Kendall 345 kV circuits.

Preliminary substation package

The 10% Kerr Data Center 1 package covers a planned 1,050 MW net, 345/34.5 kV substation: preliminary one-line, arrangement, site and equipment information.

Proposed route schematic: 7.0 mi at 345 kV, I-10 crossing, midpoint PEC tie and on-site switchyard.

Required outputPurpose

HB-KILO-SA · REV 3.2 · 2026.09.16

Agree the tenant brief and the next diligence scope.

The proposed outcome is a defined work program and decision record; no delivery commitment is established here.

Inputs to agree

Phased IT load, cooling and water assumptions, network and resilience needs, operating requirements and desired timing. Desired dates remain requirements to evaluate, not project commitments.

Outputs to commission

A reconciled campus planning basis; an evidence-request register with agreed owners, dates and costs; and an integrated schedule linking open conditions to subsequent commitment decisions.

Decision to record

Confirm whether the tenant and development team wish to proceed with the scoped diligence. Define the evidence needed before a commercial or delivery commitment.

Illustrative design option. Containerized storage may be evaluated within the tenant brief. The retained record does not establish a storage capacity, procurement commitment or deployment date.
