I think I understand what you're after. Maybe draw up a quick sketch and
attach it here. Show all the different things that can happen and what the
subassembly should do. For example, what if the 2% slope intersects the
ground before 5'? What if 25% still doesn't meet ground before the ROW? I
would imagine for these scenarios, do nothing, since you're looking to
redesign in those areas?
With that many constraints I can't think of any particular subassembly that
comes with Civil 3D. You can hire someone to create one however. It
shouldn't be tough. Grading won't do what you want at all.
What you could do is attach (at BOC) the daylight min width at 2% AND (at
BOC) attach the daylight max width at 25%, label the grade of the links and
then go section by section looking at the numbers to see how they work.
You'll see 2 daylight lines, each with grades. Then you can decide where
you need to redesign.
