Terrain cross-check (USGS 3DEP)
FAA 1039 ft MSL · USGS ground 783 ft · Δ 256 ft
Differential consistent with an elevated / rooftop pad
Structure cross-check (Overture / OSM)
Rooftop pad — the coordinate falls on a building footprint
Building height ≈ 48 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 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
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.

Form 7480 · 204 ft AGL — Proposed private-owned and private-use hospital heliport landing area (H2) to be established at the existing Nationwide Children's Hospital (OI95) which is located in Columbus Ohio. The existing heliport landing area (H1) is proposed to remain. IFR Procedures are anticipated.
The FAA record places this pad at 1039 ft. USGS terrain plus the building put the actual rooftop at 831 ft — a -208 ft difference the federal record doesn’t carry.
eVTOL footprint
The 50 ft pad is 50 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.
