The city is no longer on the radar screen of General Motors Corp. as the location for a new Chevrolet dealership, according to Melanie Mintz, the city's interim community development director. Representatives of the Detroit-based auto giant appeared at a Design Review Board meeting in February of last year to present preliminary drawings of a structure to be located on the site of the now-closed Orchard Supply Hardware store next to Interstate 80 freeway at 1751 Eastshore Blvd. At the time, GM proposed to raze the OSH building and replace it with a new structure featuring a two-story showroom with offices on the second floor and service areas with parking above.
