Terrain cross-check (USGS 3DEP)
FAA 717 ft MSL · USGS ground 660 ft · Δ 57 ft
Differential consistent with an elevated / rooftop pad
Structure cross-check (Overture / OSM)
Rooftop pad — the coordinate falls on a building footprint
Building height ≈ 40 ft — measured independently of the FAA record
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 56 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

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 — 7480-1 to move an existing heliport 775' to the southwest. It will be on the rooftop of the same building. The existing pad will be closed and dismantled when the new one is opened.\r\nPlease note: The Alsip Fire Department Heliport was incorrectly listed on the 7480-1 as .28 NM from the proposed facility - that should be 2.8 NM.

DATA INTEGRITY
Surface elevation
The FAA record places this pad at 717 ft. USGS terrain plus the building put the actual rooftop at 700 ft — a -17 ft difference the federal record doesn’t carry.
eVTOL footprint
The 44 ft pad is 56 ft short of the 100 ft an eVTOL FATO requires (measured).

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.
