Maybe a little early for a thread on this one, but why not? We've had some discussion on it in the SF Rundown thread, but I'll add a couple of tidbits again here.
They're going to auction this parcel (in September) rather than the typical RFP process. There will be sealed bids, then an option for the participants to raise their bids verbally in person. The winner will be approved the following week and their payment will be due by the end of the year. So no renegotiating after being selected like Hines did on the Salesforce Tower site.
It is zoned for 750' to the roof, which in SF means with mechanical screens/parapets/crown/etc it can reach up to 825' (assuming 10% is allowed, though if I'm reading
this correctly, it is only 7.5% for buildings over 550').
Finally, at least 2/3 of it must be commercial, so there's the potential for mixed use here.
