Determination of no hazardDetermined - No Hazard306 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

"Requesting approval for proposed frequencies. All other frequencies previously filed are still in operation. We request no change to the tower lighting that was originally determined under FAA Circular 70/7460-1K and wish to keep the steady burning side markers at this time."

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.
