Boston's Election Department plans to hold a recount of ballots cast in the District 7 race on Friday. Althea Garrison, a former state representative and a perennial candidate who came in third place, requested the recount.

Garrison collected signatures from three wards -- Wards 8, 12 and 13 -- in order to qualify for the recount, which is scheduled for 10 a.m. in the Election Department offices.

In the preliminary election held on Sept. 27, the field of four candidates was narrowed to two contenders: incumbent City Councillor Tito Jackson and Fenway's Sheneal Parker.

Jackson, who won a special election in March after former City Councillor Chuck Turner was ousted because of a bribery conviction, received 76 percent of the vote in September, or 1,875 votes. Parker picked up 274 votes, while Garrison grabbed 216 votes. Roy Owens, another perennial candidate, received 85 votes.

District 7 includes Roxbury, Dorchester, the South End and Fenway.

The recount pushes back the ballot order drawing that was originally scheduled for Tuesday. The drawing, which will determine the ballot order for all the district races and the City Council At-Large contest, will likely occur at 4 p.m. Friday in City Council's chamber.

The final election, with a seven people on the ballot for the City Council At-Large race, is set for Nov. 8.
