The Seven Corners Shopping Center has asked Metro to eliminate the center's parking lot as a jumping-off place for Metro's popular express bus service to Redskins football games after this Sunday's game.

Joseph Alexander, a member of the Metro Board and a Fairfax County supervisor, made that announcement at the Metro Board meeting this week, adding: "This is serious. There are about 1,000 Redskins fans who park there."

Thomas S. Trimmer, Metro's director of bus services, said yesterday that "we are searching for a substitute staging area after this Sunday's game." Trimmer said that Seven Corners riders to the Redskins game against Philadelphia Sunday will be asked their addresses "so we can try and find the most convenient area to move to."

Robert O'Brien, shopping center manager, confirmed that Metro had been asked to move but declined to answer other questions. "I don't understand why this is the business of the newspaper anyway," he said.

Alexander said that the shopping center management, which unquestionably has control of the parking there, is concerned that the Redskins crowd is taking places away form Sundy shoppers. About 500 cars usually use the Seven Corners lot to catch the Redskins buses, Northern Virginia Transportation Commission officials estimated. There are about 3,400 parking places at Seven Corners.

Redskins bus service is one of the few things Metro does that makes money. Metro charges $3.50 for a round trip from Seven Corners to RFK Stadium and runs as many buses as are necessary. Metro provides bus service to Redskins games from 13 locations around the metropolitan area.
