⚠ Location-suspect — recorded coordinates may be mislocated
Terrain cross-check (USGS 3DEP)
FAA 546 ft MSL · USGS ground 45 ft · Δ 501 ft
Differential consistent with an elevated / rooftop pad
Structure cross-check (Overture / OSM)
Ground-level — no building footprint at the coordinate
Cross-source consensus
⚠ Sources conflict — FAA elevation sits above terrain, but no building is at the coordinate
Either a freestanding / tower pad or a mislocated coordinate — independent verification recommended.
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 65 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.
IBC references NFPA 418 for rooftop facilities. Standalone fire code reference not confirmed.

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.
