The Chicago Cubs have received permission to add 70 "bullpen box seats" along the third base line and install additional digital signage at Wrigley Field.
The additional seats had to be approved by a permit committee of the city Commission on Chicago Landmarks, as the city council gave the 93-year-old stadium historic landmark status in 2004.
City Hall approved the changes because "landmark buildings aren't frozen in time, need to be maintained and can be improved while respecting their history," said Peter Scales of the city's Department of Planning and Development.
The changes were approved as Gov. Rod Blagojevich and Mayor Richard Daley mull the Tribune Co.'s request to have the Illinois Sports Facilities Authority acquire and renovate Wrigley Field.
"These will be great seats and, just like the seats behind home plate, will blend in with the architecture and history of Wrigley Field," said Mike Lufrano, the Cubs' vice president of community relations.
Adding new seats to an historic park such as Wrigley is not without precedent. The Boston Red Sox have added a number of seats throughout Fenway Park over the past few seasons, including field-level box seats and a seating area perched over the stadiums famed Green Monster.
