Mayo Clinic Grainger Building-Tower Crane
Rochester, MN · near Mayo Clinic St Marys Hospital (0.6 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
"This proposal will be for the approval of the Mayo Clinic Grainger building. We will also be utilizing a tower crane to erect the building. The total height of the tower crane will be at 190' above the site elevation of (roughly 1011'). This would put the top of crane at 1199.65'."
