Antenna tower · 2026
Buttermilk - Base Area Monopoles #2
Aspen, CO · near Aspen-Pitkin County/Sardy Fld (1.2 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
"Planning to add (2) 40' monopoles approximately 55' apart behind the Buttermilk vehicle maintenance facility. The existing building is approximately 24' tall so these will not extend much above the roof line. Only about 60' away to the southwest the ski slope is higher in elevation."
