The second article is pretty clear that the $170M estimate is for the entire area. I think this puts my numbers further into perspective as they seem reasonable as a proportion of Lebreton as a whole.
10 acres is the current project, if you aren't talking about 10 acres you might be in the wrong thread, since this thread is all about the 10 acres parcel which the sens would be developing. The estimated cost you cited was for a 50 acres parcel, making it difficult to draw any conclusions from for a 10 acres development..
