During his time in city government, Ravitz often spoke against the dangers of suburbanization, racism, and the social impact of urban planning decisions in Southeast Michigan.[3]
Ravitz held several official positions in Detroit politics, including service on the Detroit City Plan Commission as Director of Community Organization and as staff director of the Detroit-Wayne County Community Mental Health Services Board.[2] He chaired the Wayne County Board of Supervisors from 1966 to 1968, as well as the Southeast Michigan Council of Governments (SEMCOG) from 1970 to 1971.[3]
Ravitz served an intermittent four-decade stint on the Detroit Common Council starting in 1961. He served as president of the council from 1969 to 1973, when he shifted focus to run in the mayoral primary election.[3]
As a relatively new city council member in Detroit, he made a name for himself in 1963 by introducing an open housing ordinance with William Patrick, the only African-American council member at the time. The ordinance would have outlawed racial discrimination in housing. The ordinance failed, but the discriminatory law enacted in its place was eventually found unconstitutional.[4]
Throughout his political career, Ravitz advocated for poor Detroiters. In his work at the Plan Commission, he was active in the formation of block clubs across the city that taught citizens political organizing skills. They also helped Ravitz develop a grass-roots political network.[5] He was often called a friend to the African-American community in Detroit, based on his effort to bring community organizations and citizen groups to the table along with powerful development interests.
Ravitz ran for mayor in Detroit in 1973, and was supported in his run by the UAW. He placed an unsuccessful third in the primary election.
After a short break, Ravitz returned to the city council and worked closely with Young, though they often disagreed. While Ravitz supported smaller developments across the city, Young favored large-scale projects downtown and along the riverfront.[4] Ravitz was especially hopeful about the use of "community development" in municipal planning decisions, but warned that many cities pay lip service to grass-roots involvement while offering back-door deals to large developers.[6]
