No data
No FAA obstacle data on file for this state. Clearance unverified.
Geometry
Requires 82 feet of expansion
Recorded pad side 18 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.
100 ft · eVTOL FATO
The recorded pad is 82 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.

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.

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.
