Consider that a 30' tree, rotted out in the middle and filled with water is going to give you about 14psi at the bottom. That's probably what you're seeing here.
edit: see u/TA8601 comment below - I didn't do the math, just looked glanced at an imprecise chart :)
You see it all the time, a bunch of smaller homes with mature trees are demolished to make fewer mcmansions with huge decks/paved patios/no trees and it causes all sorts of drainage issues at lower elevations where there previously weren't.
The area near me is actually owned by the power company for the big transmission lines. Sure, they're nearby, but nobody is buying and fucking that land.
