Owner self-reported — never independently field-inspected
Location confidence
⚠ Location-suspect — recorded coordinates may be mislocated
Terrain cross-check (USGS 3DEP)
FAA 150 ft MSL · USGS ground 8 ft · Δ 142 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 →

Obstruction screen
No data
No FAA obstacle data on file for this state. Clearance unverified.
Geometry
Meets the FATO footprint
Recorded pad side 100 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
Unverified
No obstruction data on file. The dimensional gap applies; clearance is unverified.
This pad already covers the eVTOL landing footprint as it stands.

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.
