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: 2018/02/19. Our check of the record: Self-reported (details below).
What has the FAA said about its airspace?
1 FAA airspace determination is linked to this site; the airspace finding on file is unknown. The list is below.
What is being built nearby?
3 FAA obstruction filings within 1 nm in the last 12 months, the tallest 250 ft above ground. Builders file these before putting up cranes and structures that could affect flight paths.
  • Crane, 150 ft, 0.46 nm away, filed 2026-08-03 (2026-AWP-14275-OE)
  • Crane, 250 ft, 0.54 nm away, filed 2026-07-28 (2026-AWP-13940-OE)
  • Crane, 150 ft, 0.66 nm away, filed 2026-07-24 (2026-AWP-13793-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).

eVTOL readiness

INFEASIBLE WITHOUT REMEDIATIONConversion feasibility · four readings, one line each
Obstruction screen
Severe
High obstacle within 0.5 nm conflicts with the expanded footprint and the 8:1 approach surface.
Geometry
Requires 80 feet of expansion
Recorded pad side 20 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.
Overall
Infeasible without remediation
A high obstacle conflicts with the expanded footprint. Remediation or a different site.
100 ft · eVTOL FATO
The recorded pad is 80 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

100 ft
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.
