For hospital and EMS teams

No hospital is linked to this landing site in our records. If it serves a hospital, tell us.
Is the FAA record right?
FAA status: Open. Last FAA inspection: none on record (common for private-use pads, which the FAA does not routinely inspect). Last update from the owner: 2025/06/03. Our check of the record: Corroborated (details below).
What has the FAA said about its airspace?
No FAA airspace determination is linked to this site in the records we hold.
What is being built nearby?
2 FAA obstruction filings within 1 nm in the last 12 months, the tallest 400 ft above ground. Builders file these before putting up cranes and structures that could affect flight paths.
  • Crane Tower, 400 ft, 0.55 nm away, filed 2026-08-31 (2026-AWP-15917-OE)
  • Crane Tower, 321 ft, 0.55 nm away, filed 2026-07-31 (2026-AWP-14097-OE)

Keeping the FAA record right
  1. See your official record in the FAA's Airport Data and Information Portal (ADIP).
  2. To correct it, the facility manager signs in to ADIP and uses Airport Master Record, Update Facility Data (Airport/Heliport). The paper private-use form 5010-2 was retired in July 2024.
  3. Building, changing, reopening or closing a landing site needs notice to the FAA on Form 7480-1 (14 CFR Part 157).

AirIndex compiles public FAA, federal and hospital records and checks them against each other. It is not a source for navigation or flight planning; use official FAA sources and your operator's procedures. See something wrong? Report a correction (how corrections work).

Recorded pad side 100 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.

Obstruction screen passed. Geometry and structural capacity remain open. Site validation required.

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.
