Obstruction screen
No data
No FAA obstacle data on file for this state. Clearance unverified.
Geometry
Requires 70 feet of expansion
Recorded pad side 30 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
Unverified
No obstruction data on file. The dimensional gap applies; clearance is unverified.

The recorded pad is 70 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

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.

    Other · 0 ft AGL — Proposal to change Clear Lake Heliport from private use to public use. Existing heliport consists of two helipads. Helipad number 1 has a 30' x 30' turf touchdown area and was originally studied under Airspace Case No. 95-AGL-461-NRA. Helipad number 2 has a 30' x 30' touchdown area and was originally studied under Airspace Case No. 00-AGL-0456-NRA. This case will be circularized for public comment. It appears that both helipads meet current design criteria when utilized in accordance with the airspace determinations. A lighted wind sock and lights for the east pad are provided. ADO has no objection with provisions. Please see hard copy for additional details.

INGRESS & EGRESS WILL BE LIMITED TO 180 DEGREES MAGNETIC THROUGH 270 DEGREES MAGNETIC. ADO HAS NO OBJECTION.
