U.S. Senator Carl Levin and the "Detroit Blight Authority" are backing efforts that would clear out nearly three dozen blocks of abandoned homes in the city. Under the plan about 70 would be demolished at a cost of about one million dollars. The "Detroit News" is quoting Levin as saying "you can't tear down a house here, a house there." He says if you don't tear down all the houses in an area "the blight will gradually grow." Final approval is expected soon and then work could start later this spring.
