I may be listing a home in the Enclave @ Glen Abbey shortly which is one of the subdivisions that is in 30022 and was built in 2006. If you would like to see this house I would be happy to show it to you before it goes on the market. I happen to live in 30022 and love it. I've been here for 10 years and know the area very well. I have two kids in Dolvin Elementary school (one will be going to Autry Mill Middle next year) and am very involved with school activities. I'd be happy to answer any questions you might have about the area.
Other neighborhoods that have been built since 2005 are (some of these may have resales instead of new construction):
Enclave on Johns Creek
Jones Bridge Estates
Registry at Kimball Bridge
Hope this is helpful,
