Owner self-reported — never independently field-inspected
Location confidence
No coordinate anomaly detected
Terrain cross-check (USGS 3DEP)
FAA 77 ft MSL · USGS ground 38 ft · Δ 39 ft
Differential consistent with an elevated / rooftop pad
Structure cross-check (Overture / OSM)
Rooftop pad — the coordinate falls on a building footprint
Building height ≈ 44 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 →
The recorded pad is 12 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

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.
Obstruction clearance
High obstacle within 0.5 nm — conflicts with the expanded footprint and 8:1 approach
Measured against FAA pad geometry and federal FATO sizing (EB-105). 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.
