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

"Replacement of a concrete sidewalk curb ramp."
