The Planning Department just released their 25-year plan for the Transbay Terminal-adjacent "Transit Center District." Above is a rendering of what the San Francisco skyline might look like, 20 or 25 years hence, if six new proposed skyscrapers actually get approved and built, including the central 950-foot Transbay Tower, which would be 100 feet taller than the TransAmerica Pyramid. This is just a plan of course, not a design, and the image above is meant only to illustrate relative heights. But wouldn't that be pretty? The view from Dolores Park? (Cue the anti-shadow, anti-tall-stuff whiners.)
In addition, the plan covers a 145-acre district bounded by Steuart and New Montgomery Streets, between Market and Folsom, giving landmarks status to four buildings including the Palace Hotel.
