Using feedback from the 2018 cityhood effort, the map size and population was reduced. Aiming to have a population of 50,000-60,000 residents, the intersection of Johnson Ferry Road and Roswell Road/120 was established as a center point. The main thoroughfare is Johnson Ferry Road from its southern most point at the Chattahoochee River to its northern most point at Shallowford Road. From there, the map was extended as far east as possible, to the Cobb/Fulton border and equidistant west. The reapportionment office creates maps using federal census blocks and natural barriers, creating what you see to be the western boundary of the proposed city of East Cobb.

School attendance zones are unrelated and have no correlation to the city map.

Some voter precincts are split. This is not an unusual occurrence and has been the case in other cities and counties with no detriment to the voters or the community.
