Even if you are stuck with using a water system or a water/foam system take a good look at the Compressed Air Foam sprinkler systems out of Canada that have just recently garnered UL listing and FM approval. These happen to address the containment and curbing issues by using a miniscule application rate compared to the other systems.

Section 6.4.2.5 deals with curbs, scuppers, special drains, ect....and
states that "If a drainage system is used, it shall have sufficient

protection systems and hose streams."
If there is only curbs does this apply since there is technically no
drains?  If so, what is the proper way to determine the expected
discharge?
