MARTA, the transit authority for metro Atlanta, is planning to use its excessive parking and develop under-used parking lots at three stations - King Memorial, Avondale and Edgewood/Candler Park - into mixed-use commercial and residential buildings. With the new projects, MARTA will lease the land—typically for 99 years—to developers planning mixed-use, transit-oriented buildings. They hope to help revitalize both communities and increase the number of people who use public transit.
