The Council created a districting committee to propose several different possible district maps and hold public hearings before presenting one plan to the Council to approve. State law required the City Council to make a final decision on the districts within 90 days of being notified that the referendum had officially passed, meaning that the Council voting on the districts would be the 1982 Council, not the 1981 Council creating them. Then-president Patrick McDonough, who opposed district representation, appointed Rosemarie Sansone, a major advocate of district representation, as chair of the districting committee, but chose Frederick C. Langone, Dapper O'Neil, and John W. Sears as the other three members, all of whom opposed district representation. Both Langone and O'Neil would be returning to the Council in 1982, but Sansone did not run for re-election in 1981 and would not be able to vote on the district boundaries if the committee did not work quickly to present a plan to the Council before the end of the year. Public hearings over possible district boundaries were full of heated debate between advocates of drawing lines to protect neighborhood unity and advocates of drawing lines to create two predominantly minority districts and give minorities a voice in local government. Contention centered around Dorchester and the South End. Dorchester, Boston's largest neighborhood, needed to be split into at least two districts. A simple split in half would create either a north and a south district or an east and a west district. An east district would be largely White (75% or greater) and a west district would be largely African-American. North and south districts would have less extreme majorities. Many residents were opposed to both divisions, stating that they would increase racial segregation in Dorchester and continue the political powerlessness of minorities. A more complicated split taking into account areas with large minority populations would create one predominantly minority district and one predominantly white district but treat Dorchester as several smaller neighborhoods to be divvied up among surrounding neighborhoods rather than as one community. In various proposals, the South End, due to its location, was grouped with either South Boston or Back Bay/Beacon Hill by advocates of neighborhood unity, or Roxbury by advocates of minority-dominated districts.
