I believe many of the appeals you mentioned are legitimate, but I suspect they will be a difficult sell to a place that has no existing model of what effective development looks like. Some of them are subjective as well, and that's tough to play against what looks like a tidal wave of money to the city.
It may be helpful to frame the conversation from a financial standpoint, if at all possible. Maybe try to spur your council to dig in on the realistic revenues and expenses of such a development. I'm sure that won't be an easy path, but it may allow you to make more objective appeals.
