eVTOL readiness
INFEASIBLE WITHOUT REMEDIATIONConversion feasibility · four readings, one line each
Obstruction screen
Severe
High obstacle within 0.5 nm conflicts with the expanded footprint and the 8:1 approach surface.
Geometry
Requires 46 feet of expansion
Recorded pad side 54 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
Infeasible without remediation
A high obstacle conflicts with the expanded footprint. Remediation or a different site.
The recorded pad is 46 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.
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.

Heliport · 55 ft AGL — THIS IS AN EXISTING HELIPORT. THE ALTERATION IS A 22 DEGREE CLOCKWISE ROTATION OF THE EXISTING WESTERN FLIGHT PATH. TO MAINTAIN OBSTRUCTION FREE INGRESS AND EGRESS ROUTES THE FLIGHT PATH IS REQUIRED TO BE ROTATED DUE TO CONSTRUCTION OF THE HOSPITALS FUTURE DEVELOPMENT PLANS. THIS WILL MAINTAIN THE 8:1 APPROACH/DEPARTURE PATH. SEE UPLOADED DOCUMENTS. DUE TO AGE OF THE PREVIOUS APPROVAL DATE A NEW APPLICATION WAS REQUIRED FOR THIS CHANGE.

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.
