ISO concluded its review of the fire suppression features being provided for Tiffin FPSA. The
resulting community classification is Class 04/4Y.
If the classification is a single class, the classification applies to properties with a Needed Fire
Flow of 3,500 gpm or less in the community. If the classification is a split class (e.g., 6/XX):
The first class (e.g., “6” in a 6/XX) applies to properties within 5 road miles of a
recognized fire station and within 1,000 feet of a fire hydrant or alternate water supply.
The second class (XX or XY) applies to properties beyond 1,000 feet of a fire hydrant
but within 5 road miles of a recognized fire station.
Alternative Water Supply: The first class (e.g., “6” in a 6/10) applies to properties within
5 road miles of a recognized fire station with no hydrant distance requirement.
Class 10 applies to properties over 5 road miles of a recognized fire station.
Class 10W applies to properties within 5 to 7 road miles of a recognized fire station with
a recognized water supply within 1,000 feet.
Specific properties with a Needed Fire Flow in excess of 3,500 gpm are evaluated
separately and assigned an individual classification.
