You're right about development in the "Nine Oaks Lane" area being relatively new. It's a nice area located about a mile east of a nice open air mall and on the south side of the city. I don't find any crime data for that street either, but City-Data.com rates Collierville as having a "low" crime rate. Collierville also has highly rated public schools including elementary, middle school, and a high school. My wife and I live only a few miles east of Nine Oaks Lane in the small city of Piperton TN, and we love it here. We shop in Collierville all the time and like to eat out at several of the restaurants in the open air mall area. We relocated here from Portland Oregon and are quite familiar with the challenges of relocating to a new community. Let me know if I can help make your transition easier.
Always My Best,
