Chris, Is there any particular reason that 12.2.2.1.2 doesn't apply?
Seems to me your storage is less than 12' high, which sends you - eventually - to table 12.1.10.1.1, where there's a series of protection methods for Group A plastics < 12' high. What you end up with for Group A, solid (unexpanded), exposed, storage 5'-0" or less has a density requirement of 0.20 gpm/sqft over 1,500 sqft. That would most likely be not nearly as demanding as your 25/35 rack storage. That's the way I'd approach it.
