In 1966, after the Voting Rights Act of 1965 (VRA) was passed, the city amended its charter with approval by the state legislature, reducing the number of wards from nine to three, with commission members to be elected by at-large voting to numbered positions, three for each ward, with three wards in total. Candidates were required to win by majority vote, with run-off elections between the top two candidates for each seat if no majority emerged after the first round of voting.
