Determination of no hazardDetermined - No Hazard110 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

"Proposed 110-ft crane for the collocation of T-Mobile antennas on an existing water tank. Structure height not increasing. Structure covered under existing FAA DNH 2020-ANM-4402-OE."
