- "Officer Foley had to admit it. There were some parts of her job she like a lot less than others. And taking tranks and addicts home was to be on the bottom of her list. She scanned the street as they landed [their squad car] — hard to believe this neighborhood had once been a nice place to live."

- "They ought to tear this whole place down. Nothing more than a breeding ground for tranks, lo-bos, and zipheads."

Hilldale was a planned neighborhood in Hill Valley. It was first constructed around 1985 and existed to at least 2015. It appeared to cover a large area over several blocks of town. A railroad line that connected to Eastwood Ravine ran behind the development, which became the location of destruction for the DeLorean time machine.
In 1985, people anticipated Hilldale to be a cool location; however by the 2010s, it had become rundown much like Lyon Estates. The sign at the entrance was graffitied over, with the wording Hilldale: The Address of Success crudely altered to Hilldale: The Address of SucKeRs.
Marty McFly and his wife Jennifer lived there with their family. When Doc Brown arrived with younger 17-year-old Marty there, the teen was excited with the idea that his future home would be there, not knowing the rundown status it would devolve into.
However, with the alterations to the timeline that followed, it remains uncertain as to whether they lived there afterward.
Behind the scenes
- It is interesting to note that Hilldale is only ever seen fully on-screen after old Biff absconds with the sports almanac in the DeLorean and travels to 1955, suggesting that Hilldale's rundown appearance itself is the result of the changes to history beginning to 'ripple' forward into 2015 — thus changing it to 2015A.
