Putting up a shop in CA - fire department being a pain

Not trying to be a jerk here, but have you asked them if they have 150' of hose on their 70,000 lb. trucks...
I have never heard of such nonsense, and I deal with the local fire dept. regularly and have done so for years. How do they respond to farm or brush fires?
Oh, I see you're in CA... do they want you to install charging stations for the electric firetrucks they're going to be required to get, also?
I feel sorry for you. Speak with your local building inspector or local councilman/woman.
