That's happening here as well. Eastward expansion from the Richmond suburbs as well as westward from Hampton, Newport News. Areas that were once primarily agriculture now being considered for new housing (We have a development across from us with an expected several hundred homes being developed).
There are a couple of things happening here. 1) Older farms where the owners have passed on, the kids have moved and none of them want the property. 2) Population growth in the older cities and locally is either pushing folks out of Richmond and Newport News or an influx of retirees (guilty) looking to relocate from either northern climes or escaping Florida and South Carolinian. Throw in the usual addition of military transfers.
The old timers complain. But forget that the decided to move here 10,20,30 years for basically the same reasons.
