Mits smiles waves to the police,
"Ohai, Weston's finest! Can someone please call an engineer to tell me exactly how many 3' diameter concrete footers it would take to hold up that hunk of pavement once the para making it float is knocked out? I'd really rather not have to just guess. Worse comes to worse I can ask my friend Matt to make sure it safely crash lands without destroying anything, but I'm sure everyone would prefer it not crash at all."
She then smiles and waves to Wraith,
"Ohai, Wraith! I can get you up there. And provide ice cleats so you don't fall off the dome."
Quick-snap ice cleats and portal to top of dome are offered. Why not just open a doorway to the
inside of the ice dome? She wants Wraith to be able to get in on his own terms. Also, her portals aren't 1-way. Opening a door to the inside of the snow globe would put police and EMTs in danger.
Mits then looks up to the window where Daniel was.
"Hey up there! If you still wunna smite villains, I can teleport you to 'em. No problem! Just say the word."
Meanwhile, since ice face's ice dome has effectively eliminated the badguys as an immediate threat, Miss Adventure lines up the defeated baddies nice and neat for the police to restrain and EMTs to treat for electrocution.
"To my knowledge there's only one civilian casualty, and he's being treated by Lifelight. As always I have full video of the whole event and will be happy to make copies and testify at the DA's convenience."
Then opens a small portal just within the ceiling of the ice dome to pipe in some travel music for the villains:

away from her nice stereo (that's at her secluded secret lair) in case they decide to try and use her portal to destroy it.
