> The city is currently parking ambulances and dump trucks on millions of dollars worth of Strip District property.

I think that was part of the original plan for the site, though from the City Paper article it sounds like that may have been one of the items that got cut due to the cost inflation.

https://pittsburghpa.gov/press-releases/press-releases/5397 > The project will save millions of taxpayer dollars currently spent on leases by relocating public safety operations and public works storage from around the city to the campus. The City plans to bring Emergency Medical Services headquarters from Shadyside, Police Headquarters from Chateau, Police Training Academy from Allegheny West and the vehicle repair shop from the Strip District. The plan also includes building an indoor firing range on the campus to move it from its current location in the Highland Park neighborhood. Locations that will be vacated that the City currently owns can be sold to be put back on the tax rolls and redeveloped to benefit neighborhoods.
