Antenna tower · 2026
w/Antennas HAWTHORNE HILLS
SEATTLE, WA · near Harborview Medical Center (5.3 mi)
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
"Increasing antenna tip to 50ft. This site will comply with the operational parameters agreed to in collaboration with the FAA as part of its 5G C-band compatibility evaluation process as they may evolve over time."
