To keep the momentum here going. :^)
Here are some mockups of what Penn "may" build (it is not yet approved by the Board so for Entertainment Purposes only at this point) at 3600 Civic Center Boulevard, between the Colket building of CHOP and the existing parking garage. This would fill the hole in the ground that is there now. It is the smaller lot on the left of the two. This is an old picture, especially since CHOP's ambulatory building is nicely filling out the right-most empty lot:
The back 2/3's of the lot will be a 1,500 spot parking garage with the front 1/3 developed afterwards. While I did not hear a timeline specifically, the garage is needed ASAP if Penn is to take down the Penn Tower garage. Diagram below:
This is a simpler mock-up of what it could look like:
Here is one apparent version:
And here is another apparent option. This one has the CHOP ambulatory in the shot:
