NFPA 14: Rooftop Hose Connections

[Haldorson]

I have a 4-storey mixed-use building where the top two storeys are split-level residential suites. The exit stairway terminates at the third floor. How does one comply with NFPA 14 (2007), 7.3.2.(5) when the standpipe terminates a floor below the roof? It seems compliance is impractical in this case and so has anyone ever had this situation come up and have a recommendation?

What building code and edition is the project designed to?

Forgot to ask but assume the entire building has a fire sprinkler system

If you look at # 5 in the 09 it says "where"
