A developer wants to bring what he calls the nation's first inclined indoor wingsuit facility to Lehi's Triumph Boulevard corridor.

Clark Robinson is asking the Lehi Planning Commission for a conditional use permit and a glass-facade exception to open the facility at 2959 N. Triumph Blvd., according to a city posting on Engage Lehi. The commission will hold a public hearing on the request Thursday, Sept. 24, at 7 p.m. in the Lehi City Council Chambers, 131 N. 100 E.

An inclined wind tunnel lets flyers wear wingsuits and glide forward on an angled air column, unlike vertical wind tunnels used for standard indoor skydiving. The technology was developed in Stockholm, Sweden, where the first such tunnel opened in September 2017, according to Inclined's website. The company currently operates two European locations, in Stockholm and Žirovnica, Slovenia. No U.S. location exists.

Robinson described the Lehi project as the first inclined indoor wingsuit venue in the United States, according to city staff's summary of his application. The only other announced U.S. facility, in the Kissimmee, Florida, area, was projected to open at the end of 2022 but does not appear to have done so.

Indoor wingsuit flying falls under Lehi's Commercial Entertainment Facilities category, a conditional use in the commercial zone where the parcel sits. That classification gives the Planning Commission authority to impose conditions aimed at reducing noise or other impacts.

Robinson told city staff that noise from the facility would be less than noise from neighboring Interstate 15. He said traffic and parking would not be an issue.

He is also requesting an exception to the city's requirement that 40% of a building's first-floor facade facing a frontage road be glass. Robinson argued that the wind tunnel machinery sits on the first floor, is not visually appealing, and that placing it behind glass would weaken the building's structural integrity and increase noise.

No details on the building's size, construction cost, projected jobs, or opening timeline appear in public records as of Sept. 20.

Lehi city planner Brittney Harris is the staff contact for the project. Residents can submit comments through the Engage Lehi page or attend the Sept. 24 hearing at 7 p.m. The city's public hearing notice lists the wingsuit request alongside five other agenda items, including a 405-townhome subdivision and a Taco Bell site plan.
