So, my grandmother lived in Daytona until she died, for like most of my life [she'd lived in Nevada before that, but when my poppop died when I was 5 [and we lived in Frankfurt, W Germany], I told her to go and take care of her mom [and she did?!]
Her building has to have pumps for the barely below* ground parking decks because of constant flooding - and Daytona isn't like Pensacola - it isn't nearly as rainy. Water seeping could be part of it, though its on the Halifax side.
*I say barely because the two buildings are built on this fairly thick platform, like a couple of stories, and while some of that might be lower levels in the buildings themselves, I think the parking is in that as well as a little below.
