suburb of los angeles. it is home to magic mountain, a huge mall, 3 colleges, about 60 public schools spread out through its 5 major incorporated divisions: saugus, valencia, stevenson ranch, newhall, and canyon country. there is some confusion whether castaic is incorporated. about 150,000 people live here. builders like Newhall Farm and Land want to build 60000 new homes because everyone wants to live here, although since these homes will be just slightly outside of the city limits, the city is trying to buy the land away from them to not overpopulate the city.
