The Forestville Fire Protection District has an ISO Public Protection Classification Rating of 4 for properties located within 5-road miles of the District's fire station and a Class 10 for those properties located over 5 miles from the District's fire station.
Fire alarms: 10%
Ten percent of the overall grading is based on how well the fire department receives fire alarms and dispatches its fire-fighting resources.
ISO field representatives evaluate the communications center, looking at the number of operators at the center; the telephone service, including the number of telephone lines coming into the center; and the listing of emergency numbers in the telephone book. Field representatives also look at the dispatch circuits and how the center notifies firefighters about the location of the emergency.
Engine companies: 50%
Fifty percent of the overall grading is based on the number of engine companies and the amount of water a community needs to fight a fire.
ISO reviews the distribution of fire companies throughout the area and checks that the fire department tests its pumps regularly and inventories each engine company's nozzles, hoses, breathing apparatus, and other equipment.
ISO also reviews the fire-company records to determine:
Forty percent of the grading is based on the community's water supply. This part of the survey focuses on whether the community has sufficient water supply for fire suppression beyond daily maximum consumption.
ISO surveys all components of the water supply system, including pumps, storage, and filtration. To determine the rate of flow the water mains provide, we observe fire-flow tests at representative locations in the community. Finally, we evaluate the distribution of fire hydrants.
