Atlanta ward system
From its incorporation in 1847, the municipal boundaries Atlanta, Georgia were extended repeatedly from a small area around its railroad station to today's city covering 131.7 square miles (341 km2).
Prior to 1954, Atlanta was divided into political divisions called wards. The number of wards grew as the city grew.
City is incorporated — city limits are a 1-mile (1.6 km) radius from the zero mile marker of the Western & Atlantic Railroad. City covers 3.14 sq mi (8.1 km2), 2,010.6 acres (813.7 ha).
The 1848 charter only specified election of six citywide councilmembers, but on January 9, 1854, an ordinance was adopted that divided the town into five wards and two councilmen from each ward would be elected to coincide with the completion of the first official city hall. The next election with the new rules on January 15, 1855, decided those first Ward bosses who would serve with the short-term mayor, Allison Nelson. The boundaries were as follows:
On March 12, city limits expand to a one-and-a-half mile radius from Union Depot.
During a huge boom of post-war building, two new wards were added from parts of the First, Fourth and Fifth to reflect the changing look of the city.
A new city charter was approved by Governor Smith on February 28, 1874, which reduced the number of wards back to five and created a bi-cameral council of two councilmen from each ward and a second body of three at-large aldermen was established. Each year one of the aldermen would be up for election and during his last year in office would serve as president of the other body. They acted separately on finances but together for all other business.
The new ward layout was as follows:
On November 5, 1883 a Sixth Ward (beige) was carved out of the Fourth and Fifth Wards. Its boundaries started at Butler and the GRR (today's Grady Hospital) north to North Ave at Myrtle St, then up Myrtle to the city limit at 3rd St. Follow the arc of the city limit to Williams, south to Cain (International) then James (Church) to Forsyth south to the tracks then east on the tracks to origin. This separated the wealthy Peachtree corridor from the other parts of north Atlanta. (Garrett Vol II, p. 53–54)
