Data integrity

53/100
Self-reportedData Integrity Index
Independent inspection
Owner self-reported — never independently field-inspected
Location confidence
No coordinate anomaly detected
Terrain cross-check (USGS 3DEP)
FAA 1055 ft MSL · USGS ground 1063 ft · Δ -8 ft
Structure cross-check (Overture / OSM)
Rooftop pad — the coordinate falls on a building footprint
Building height ≈ 44 ft — measured independently of the FAA record
Cross-source consensus
⚠ Sources conflict — pad is on a building, but FAA elevation reads ground level
Stale-low FAA elevation (the 6FD8 class) — never updated for the rooftop pad. Treat the recorded elevation as unreliable.

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 →

Load-bearing FATO

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.

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.
