Is the argument to keep these 3 buildings in River North because they are in River North and there are fewer of them, or because these particular style of buildings should be preserved in general? From what I see in the google map link, these don't appear to look any different from the thousands of other buildings throughout the city like them. The replacement is not stellar by any means, but when property value goes up, won't that continue to force greater utilization of the land?
