I think this site circulation, including loading, will work. It will require a core at the Admin for both public and freight since the ring circulation has to pass above the loading before dropping down to the T1 floor level. On the other side, there is possibly enough length to ramp from the T1 floor level (+102) to the plaza level (+107) with a 1:20 ramp (no handrails, no landings req). Collections will be at +106, midway up the ramp, which is actually more native to the existing site elevations.
Also looking at splitting the ring at the big gallery as opposed to growing it, but not sure if it looks so good yet. Will continue to look at that back area when I am in San Diego.
