On a building footprint — height not tagged in the source
Cross-source consensus
⚠ Sources conflict — pad is on a building, but FAA elevation reads ground level
Stale-low FAA elevation (the 6FD8 class) — never updated for the rooftop pad. Treat the recorded elevation as unreliable.
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 50 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
Clear — no obstructions within 0.5 nm on the FAA obstacle file
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.
