Right, because that has never happened in the history of making deals.
Also, it's a framework that they had agreed on, which is basically an agreement to agree.
The City has basically done just that - by saying they need $4 million for climate stuff and $12 million for road/sidewalk/right of way - and that the City is prepared to contribute an additional $6 million. Gondek just got out in front of it with the tweets. That said, the devil is in the details and it's tough to provide any meaningful judgement on that without knowing precisely what that additional work entails.
If CSEC is not prepared to accept the revised framework and is ready to stay at the Saddledome for the near future, great - the current plan in the current timeline has cost overrun stamped all over it.
I am not opposed to public funding going towards a project that is a public benefit, however I think the current proposal is shitty anyways, and that land would be better suited to intensify residential density, diversify, and provide affordable work/live opportunities in the downtown area.
At the very least, CalgaryNEXT would have provided a benefit to the community overall by removing blight and significant pollution, and created a necessary transit hub for transit oriented development on the west side of downtown. For roughly the same financial contribution.
