No heliport precedent — typically the binding gate for rooftop and hospital pads.
Obstruction clearance
Clear — no obstructions within 0.5 nm on the FAA obstacle file

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 — Establish two private use concrete surface helipads at the Mayo Clinic Hospital in Phoenix Arizona. Both helipads are 50 feet by 50 feet and approximately 10 feet of distance between the two. Also evaluate new construction of a single story radiology building adjacent (south-east) to heliports H1 East and H2 West. Construction on the radiology building will begin on 01-31-2012 and estimated to be completed by 10-28-2012. Helipad 1 (H1 East) coordinates: 33-39-31.5N 111-57-27.2W. Helipad 2 (H2 West) coordinates: 33-39-31.5N 111-57-28.2W. New Radiology building coordinates: 33-39-31.3N 111-57-25.7W.
