ambitious federal urban aid program succeeded in fostering a new generation of mostly black urban leaders. Detroit had one of the larger Model Cities projects. It promised a great deal and delivered much less, as Detroit suffered from the unintended consequences. Mayor Jerome Cavanagh (Mayor 1962—69) was the only elected official to serve on Johnson's task force. Detroit received widespread acclaim for its leadership in the program, which used $490 million to try to turn a nine-square-mile section of the city (with 134,000 inhabitants) into a model city. The city's political and business elite, and city planners, along with the black middle class, wanted the federal funding to assist the economic growth of the entire city. They sought to protect the central business district property values from nearby slums and to construct new revenue-generating structures. But, local community organizers and civil rights activists rallied poor residents in opposition to these plans. They said federal renewal funding should be used to replace deteriorating housing stock, whether with new public housing or low-cost housing built by private developers. The Model City program was terminated in Detroit and nationwide in 1974 after major race riots in the late 1960s most of its target cities. Detroit witnessed growing confrontations between the mostly white police force and inner city blacks, culminating in the massive 12th Street riot in July 1967. The riot erupted in mostly black neighborhoods. Governor George W. Romney ordered the Michigan National Guard into Detroit, and President Johnson sent in U.S. Army troops. The result was 43 dead, 467 injured, over 7,200 arrests, and more than 2,000 buildings destroyed. Thousands of small businesses closed permanently or relocated to safer neighborhoods, and the affected district lay in ruins for decades. Coleman Young, Detroit's first black mayor, explained the long-term effects of the riot: The heaviest casualty, however, was the city. Detroit's losses went a hell of a lot deeper than the immediate toll of lives and buildings. The riot put Detroit on the fast track to economic desolation, mugging the city and making off with incalculable value in jobs, earnings taxes, corporate taxes, retail dollars, sales taxes, mortgages, interest, property taxes, development dollars, investment dollars, tourism dollars, and plain damn money. The money was carried out in the pockets of the businesses and the white people who fled as fast as they could. The white exodus from Detroit had been prodigiously steady prior
