Ground-level — no building footprint at the coordinate
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 22 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.

Heliport · 0 ft AGL — This was originally airspaced as 2011-AGL-5271-NRA. The Stroger Hospital Heliport was to close when vertiport opened. The vertiport is built and now the management of Stroger Hospital is keeping their heliport open. The re-airspace is because of this change.\r\nAs requested a Google Earth shot showing the vertiport and Stroger Hospital has been uploaded 10/8/15

Heliport · 0 ft AGL — 7480-1 plus attached lists for a new vertiport. Other landing areas obstructions and \Other considerations\ are in the sheets scanned with the 7480.\r\nStroger Hospital Heliport will close when this vertiport is opened - see attached letter.

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.
