Shopping - who knows-- I can tell you that when I moved to Tracy 15 years ago there was no mall, no chain restaraunts, only McDonalds and Burger King -- it's taken 14 years to see Applebees, Chevy's, Chilis, Texas Road House, Costco etc come into town. I know that a corporation will look seriously at the number of people in the community. At this time, nothing has broken ground for shopping or restauraunts.
As to schools -- there is talk of starting Unification -- this has to happen before a high school can be built. Jefferson School District- which is in South Tracy - still does not have approval. It's a numbers game, a certain percentage of students must be of high school age before a School District can EVEN apply for unification. Once they apply, Tracy School District has to agree, etc. I don't see this happening for at least 5 years, but you never know.
