Grab your brain buckets, otherwise known as snowboarding helmets. A newly proposed indoor winter wonderland might be heading to a shuttered landfill 20 miles outside of D.C.

Fairfax County officials announced on Wednesday that Alpine-X, a Virginia-based company, has submitted a proposal to build a 450,000 square foot indoor snow sports facility that would include a 1,700-foot ski slope in Lorton, Va. The recreational facility, which is still just a proposal, has been dubbed “Fairfax Peak.” And the county seems into it.

The indoor slope would be the longest in North America and one of the longest in the world—rising to an altitude of about 280 feet, according to a press release from the county. Fairfax Peak could also include multiple competition-ready ski slopes and a bunny slope, a restaurant, a luxury hotel, and a gondola, along with place for skiers and snowboarders to shred and practice some gnarly tricks.

The proposed site of the facility is Fairfax County’s I-95 landfill in Lorton, which is currently in the process of closing. The first phase of construction on Fairfax Peak could take somewhere between 36 and 48 months—and that wouldn’t begin until after an approval process that includes community input and formal hearings. Nothing is set in stone yet.

What comes next for the site of the landfill has been a hotly debated topic. Proposals have included turning it into a park, installing wind turbines, and setting up solar panels. (Officials are evaluating how the proposed construction of Fairfax Peak could impact any future solar projects on the site.)

Springfield District Supervisor Pat Herrity says that Fairfax Peak could be a boon for residents. He touted the potential for “new jobs, exciting new snow sports opportunities, the potential for high school ski teams, new hotel and restaurant amenities for the South County area, premier national competitions and financial benefits to our taxpayers from the lease, sales tax, and hotel tax revenue streams” in the release. Alpine-X notes that the facility could also be used by military or law enforcement for cold-weather and snow training.

Officials say the indoor ski slope proposal is environmentally sustainable, noting its incorporation of energy efficient technologies.

As a public-private partnership, the county would lease its land to Alpine-X and the company would build, own, and operate the facility.
