Determination of no hazardDetermined - No Hazard158 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

"An existing water tank 146ft AGL with a new proposed 12-foot antenna on the top which will increase the overall height from 146 feet to 158 feet AGL."
