I don't think this exists. USGS elevation data doesn't show this at all.

Which is the main entrance? Are these all really entrances?

What is this new building called?

What's going on with these paths inside the building?

Cycle lanes either way, and a cycle waiting area.

Steps up to the passenger level.

Road north of here becomes Arrow Point Loop Northeast.

Pretty sure some of this is one-way.

I don't think is right at all. The road goes right through a house, for one thing.

If these are above ground, they should be mapped as building=tank or whatever it takes to show the actual shape.
