77A Alamito Creek - Fort Davis Rebuild

Marfa, TX · near Marfa Muni (4.4 mi)

Determination of no hazardDetermined - No Hazard87 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

"The Alamito Creek – Fort Davis 138kV Transmission Line Rebuild consists of the complete teardown and rebuild of the current transmission line with new wood pole equivalent and custom-designed weathering steel structures. This structure will be designed to 138kV standards and will be taller than surrounding structures to meet required electrical clearances of switch equipment."

Screening a structure of your own?

Check Part 77 and the tower's line of sight before you file

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
