The recorded pad is 60 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.

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.
IBC references NFPA 418 for rooftop facilities. Standalone fire code reference not confirmed.

Heliport · 0 ft AGL — Establish two private use concrete surface helipads at the Mayo Clinic Hospital in Phoenix Arizona. Both helipads are 50 feet by 50 feet and approximately 10 feet of distance between the two. Also evaluate new construction of a single story radiology building adjacent (south-east) to heliports H1 East and H2 West. Construction on the radiology building will begin on 01-31-2012 and estimated to be completed by 10-28-2012. Helipad 1 (H1 East) coordinates: 33-39-31.5N 111-57-27.2W. Helipad 2 (H2 West) coordinates: 33-39-31.5N 111-57-28.2W. New Radiology building coordinates: 33-39-31.3N 111-57-25.7W.

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.
