I think it'll be fine if the renders are adhered to, at the least. Friends of the Park probably strong armed that public use. I see Christkindlmarket, Taste of Chicago, 5 fields, ice rink.
I think it is a fair trade for renovating the entire current SF site into public use, and the Bears get the south lot done over with the stadium. This is the only reason why I'm OK with the envisioned proposal as we (the public) will get a boon for events and enjoyable space -
if they stick to the envisioned proposal.
To have bad news on the other side of benefitting publicly, Reinsdorf wants to only put up a max of 10% for the new Sox stadium on Roosevelt and no public tradeoff for the surrounding area as a village. He considers his own investments locally as a way of "putting up" money.
