I didn't see a thread about some of the proposals for Calgary that was never realized, so I thought I would start one (if there is one, let me know!)
With the talk about the new development plans for Eau Claire, I thought I would post this proposal to locate the City Hall,and other institutional buildings like the School Boards and the Police etc., on a site around Eau Claire, from 1957. (Note the parking, road and bridge on Prince's Island!)
