From its incorporation in 1847, the municipal boundaries of Atlanta, Georgia, United States, were extended repeatedly from a small area around its railroad station to today's city covering 131.7 square miles (341 km2).
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.
[3][4] 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.
In October 1897 Frank P. Rice drove a failed proposal to annex Pittsburgh, Reynoldstown, Bellwood, and what was then called "north Atlanta".
[6][7] "North Atlanta" was defined at the time roughly as today's Midtown, Georgia Tech, and English Avenue:[8] In 1902 a special committee made a new proposal to annex those areas as well as "Bonnie Brae", Copenhill, and the "St. Charles Avenue" area (in today's Virginia Highland).
An act of the Georgia General Assembly was enacted on August 3, 1904, which designated the area from then current city limits (at 6th St and West Peachtree), north to 15th St, then east to Piedmont Ave, then northeast to Southern Railway (basically follow Piedmont to the Ansley Park area), then southwardly along the railway the limits.
On January 1, 1909, a Ninth Ward was formed out of just annexed Copenhill, part of Druid Hills, Edgewood, Reynoldstown and East Atlanta.
[10] Annexation of 3,510 acres (1,420.45 ha; 5.48 sq mi) to the north and west:[11][12] Annexation of 2,011 acres (813.82 ha; 3.14 sq mi) including the town of Oakland City and from the previous city limits south to the BeltLine: Adair Park, most of Pittsburgh, southern Summerhill, southern/eastern edges of Grant Park neighborhood.
From there, the boundary ran due west to a prolongation of Holderness Street south of the BeltLine, and from there southwest to the junction of Campbellton and Utoy roads.
The wards were combined as such: In 1951, after a failed 1947 referendum and two other failed attempts, the state legislature passed a "Plan of Improvement" by which on Jan. 1, 1952, the city annexed 51,470 acres (20,829.2 ha; 80.4 sq mi) in Buckhead, Adams Park, Southwest Atlanta,& Lakewood, Northwest Atlanta to the Chattahoochee River/Cobb County Border.
[25] This was by far the largest expansion in Atlanta's history, tripling the size of the city to 118 square miles (310 km2) and adding 100,000 residents.
This helped spread the burden of providing public services by adding to the base a large group of mostly more affluent residents.
In December 2017, the Atlanta City Council approved an annexation request by Emory University, the Centers for Disease Control, Children's Healthcare of Atlanta - Egleston Hospital, and other contiguous property owners in the Druid Hills neighborhood of DeKalb County.
[35] The annexed area ultimately went to APS,[2] and as part of a 2019 settlement Emory would help establish school-based clinics for DeKalb schools.
