What is the formula to calculate the fire benefit charge?

The fire benefit charge is uniformly applied to all real property, (e.g., buildings). The formula is based on the Insurance Services Organization (ISO) formula for fire flow. To this we apply a Category Factor and a Fire Flow Benefit Factor to calculate the fire benefit charge for each parcel of property. Here is the formula:

Square Root of the Square Feet x 18 x Category Factor x Fire Flow Benefit Factor = Fire Benefit Charge
