What is Exurb?
1.
A sparsely populated area, that is currently making the transition from rural to suburban, located usually on the fringes of a metropolitan area. Often times, it may be populated by wealthy estates, hobby farms, as well as existing rural towns, and usually with larger, more-mainstream suburban development on the brink of happening.
That exurb is growing so fast that the town can barely keep up the services to allow it to function.
