Get an email when the record for University Hospital/Sicu changes: its FAA registration, pad data, nearby FAA airspace determinations, or AirIndex findings. A weekly digest arrives only when something changed.
Owner self-reported — never independently field-inspected
Location confidence
No coordinate anomaly detected
Terrain cross-check (USGS 3DEP)
FAA 937 ft MSL · USGS ground 799 ft · Δ 138 ft
Differential consistent with an elevated / rooftop pad
Structure cross-check (Overture / OSM)
On a building footprint — height not tagged in the source
Building height ≈ 138 ft — measured independently of the FAA record
Cross-source consensus
Corroborated — terrain and structure agree (2/2 sources)
Cross-checked against independent public data — USGS 3DEP terrain, Overture/OSM building footprints, the federal hospital registry, and measured dimensions. The State of the U.S. Heliport Record →
eVTOL readiness
INFEASIBLE WITHOUT REMEDIATIONConversion feasibility · four readings, one line each
Obstruction screen
Severe
High obstacle within 0.5 nm conflicts with the expanded footprint and the 8:1 approach surface.
Geometry
Meets the FATO footprint
Recorded pad side 120 ft against a 100 ft eVTOL FATO.
Structural FATO
Unverified
The full 100 × 100 ft FATO must be load-bearing. The FAA does not record structural capacity, so no record can confirm it.
Overall
Infeasible without remediation
A high obstacle conflicts with the expanded footprint. Remediation or a different site.
This pad already covers the eVTOL landing footprint as it stands.

eVTOL FATO required
100 ft
FAA EB-105 vertiport pattern — 2× a ~50 ft eVTOL controlling dimension, plus a 125 ft safety-area side.
Load-bearing FATO
100 × 100 ft must be structural
No heliport precedent — typically the binding gate for rooftop and hospital pads.
Measured against FAA pad geometry and federal FATO sizing (EB-105). The obstruction screen is the only reading the engine verdict rests on; geometry and structural capacity are stated separately and never folded into it. A dimensional pre-screen — site-level validation required, and independent of the underwriting risk score.

3Physically verifiedGround Truth capture
Obstructions, exact FATO geometry, surface condition, and downwash exposure require a physical Ground Truth capture — not shown above as measured. A field verification completes the record and writes the measured truth to this facility’s authority.
This page is the public data-integrity record. The full RiskIndex assessment — Q1–Q5 compliance, dimensional / FATO analysis, an underwriting-grade risk score, peer benchmark, and a sealed Site Intelligence Report — is available on request.
