Also quite visible would be the cities of Fullerton and Brea, and the Sky Cabin up the freeway at Knott's Berry Farm.
For humans 149 feet tall or shorter, Disneyland's parking structure will not be visible from Star Wars Land, Critter Country, New Orleans Square or Frontierland. The cliffs of
Star Wars: Galaxy's Edge will see to that.
I was looking at the D23 model today, from the raised viewing platform at the back of the room while everyone else crushed up against the ropes. A nice young bearded guy in a WDI shirt and Imagineering nametag came up and asked if I had any questions. We got to talking, he pointed some cool stuff out, and I asked him what he did at WDI. He said "Oh, this and that on a project we haven't announced yet, and I was the show producer for this pavilion at this Expo".
DOH! A very nice young man though.
He then explained that the model on display was originally used to get the mountains and cliffs down right, then they morphed into a display model knowing it would go to D23. The model has the "broader berm" (his words) of Disneyland's version, and explained that the model has the underground Fantasmic! boat storage shown as a cement box under the berm (which the model does), and the DHS version would obviously lack that and not need to have such a wide berm along most of the perimeter. He also explained the difference between the three entry points for Disneyland versus the two entry points for DHS.
In other words, the D23 model is based on the Disneyland footprint with a broader berm needed for the Disneyland Railroad to pass above the Fantasmic! boat storage marina hidden underground beneath the berm. Plus some artistic license by remaking north Anaheim and the Fullerton foothills into an alien planet. I found that fascinating!
