The recorded pad is 60 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.

IBC references NFPA 418 for rooftop facilities. Standalone fire code reference not confirmed.
Construction pressure: 1 crane case filed within 0.25 nm in the last 30 days (closest 150 ft AGL at 0.17 nm, FAA case 2026-AWP-14476-OE).
Situations are rules-based inferences across the obstruction, observed-operations and record layers, re-evaluated nightly; each carries its evidence and closes when the condition no longer holds.

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.
