Boston Mayor Thomas Menino approved the redistricting map and the new districts will go into effect on January 1, 2014.
The new Boston City Council district map is attached to this article with blue lines denoting the new districts. The council supported the new map, 11-2. The first two maps approved by the Boston City Council barely passed the council, 7-6, on both maps. Menino vetoed those maps, and on both occasions citing, "over-concentration of protected groups" in districts.
Legally speaking, the Boston City Council district map does not need to be approved by the state Legislature or governor to become law. Once the map is approved by the council and mayor it becomes effective, according to Boston's City Charter.
Boston is required to redraw council districts determined by the most recent US Census statistics.
The current districts, as approved in 2002, will remain in effect until the end of 2013. The 2013 municipal election would be based upon the new district configuration.
