Out Athens Highway, where sprawling homes have taken the place of family farms, retail developer Faison has built a new shopping center called North Logan Commons. Just inside the Gwinnett County line in Loganville, Mike Cohn, the head of retail development for the southeast for Faison, coaxed five new big box stores out of the ground in this economy. Best Buy, Dick's Sporting Goods, OfficeMax and PetSmart opened their doors this month in the development anchored by Lowe's Home Improvement, which opened in November. About 20 miles away in Bethlehem, near Winder, Faison also opened Barrow Crossing this month, with Belk, Publix, PetSmart and Staples anchored by Target.
