The Arabia Mountain National Heritage Area in south DeKalb County was recently named one of the region’s most innovative developments by the Atlanta Regional Commission.

The Development of Excellence award honors projects that exemplify livable designs that help with future development.

The heritage area covers 64 square miles in parts of DeKalb, Rockdale and Henry counties, including the City of Lithonia and contains all types of development from single-family homes to office properties, Stonecrest Mall and schools like the LEED-certified Arabia Mountain High School.

It also boasts the Davidson-Arabia Mountain Nature Preserve, Panola Mountain State Park, the Monastery of the Holy Spirit and Vaughters’ Farm.
