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 35 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

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.

DATA INTEGRITY
Surface elevation
The FAA record places this pad at 61 ft. USGS terrain plus the building put the actual rooftop at 52 ft — a -9 ft difference the federal record doesn’t carry.
eVTOL footprint
The 65 ft pad is 35 ft short of the 100 ft an eVTOL FATO requires (measured).

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.
