Determination of no hazardDetermined - No Hazard352 ft AGL

What this outcome means

The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.

The proposal, in the filer's words

"This building is a refiling for the same building that was filed previously in 2015 again in 2018 and most recently in 2023 with the most recent ASNs being 2023-AEA-13628-OE through 2023-AEA-13636-OE. Although the new building footprint is slightly adjusted it is still in roughly the same area and no higher than the previously filed overall height which received favorable determinations of no hazard"

Screening a structure of your own?

Check Part 77 and the tower's line of sight before you file

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
