I just got an email from Mark Olson who is CEO I think of LTO, which builds progressive housing communities for the mentally/intellectually disabled throughout the country. Here is the email and maybe it will help you (get in touch with LTO — http://ltoventures.org/communities-to-watch/):
“Ellen,
Hi! We are not building in Georgia, but I encourage you to check out a site run by a friend of mine that might have more information about possibilities in GA. The site is the Autism Housing Network (http://www.autismhousingnetwork.org/).
I will be building in Cincinnati, OH for the next few years.
Mark”
