ADA compliant landing at entry

My head is starting to hurt thinking about this.
Does the landing for ADA compliance need to be 5x5 at the entry.
I think it does. I know at turn it does, but does that apply to entry as well? Have a tricky situation here where we need the run to come out a ways from the entry to get some slope down then do a turn to make 12;1 going all the way down in the space that is available.

This might help out.
