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
"Project was previously issued favorable determinations under ASNs 2023-ANM-6656 through 6659-OE. Please do not terminate these ASNs. This project is a mixed-use development containing commercial light industrial and residential uses in a new urban setting. The project consists of several low buildings that will remain at or below 50 feet AGL."
