I find things go better if you plan for the downside and try to anticipate the problems along the way. In this case, those who badly want these towers built should be prepared to do what some of us (but, no, not me I admit) did this week and go to whatever meetings are held on the subject and speak our piece in favor of them. Wouldn't hurt to write letters to those with influence, certainly including Supervisors (especially whomever represents Twin Peaks--and who might that be exactly?), although it probably makes sense to wait until the designs are known.
But I also admit I'll be very surprised if San Francisco allows 1400 ft towers. I can tell you for almost certain that the Fire Dept. will not be thrilled (but I don't know if they'll speak up). I'll be personally happy with something over 1000 ft. I'll be ecstatic if it tops the US Bank building (or whatever that LA "tallest" is)
. Something essentially twice as tall as everything around it may be a little bit out of place. And what I'm really holding my breath for is not so much the TransBay tower itself but the Piano design--it sounds like that could be really innovative and it could actually make or break the appearance of its neighbor.
