Site Design ALT-3 - Service Drive & Walkway System OK?

[GEA]

From my solution below to the ALT-3 site design program...

1. Is it okay to have the service drive butt-up against the service entry to the building? or does the 24' wide end of the service drive have to end at the service entry?
2. "Continuous" walkway system -- Is it okay that my walkway to the office tower is a dead end? Walkability is still provided to both streets from the pedestrian plaza.

Any comments are appreciated!

Thanks
