These open houses, all identical, will include updates on potential projects, their costs and impact on existing communities and the environment. The public meetings are:

Tuesday, June 4, at the Toco Hills Library, 1282 McConnell Drive in Decatur;

Wednesday, June 5, at the Stonecrest Library, 3123 Klondike Road in Lithonia;

Thursday, June 6, at the Exchange Recreation Center, 2771 Columbia Dr. in Decatur.

A list of 40 potential projects are being whittled down to a number the county can manage and afford over the next 30 years. Everything from a MARTA line expansion down Interstate 20 to establishing light rail or bus rapid transit routes in DeKalb is on the table.
