We have revised the PPC program to capture the effects of enhanced fire protection
capabilities that reduce fire loss and fire severity in Split Class 9 and Split Class 8B areas (as
outlined below). This new structure benefits the fire service, community, and property owner.
New classifications
Through ongoing research and loss experience analysis, we identified additional
differentiation in fire loss experience within our PPC program, which resulted in the revised
classifications. We based the differing fire loss experience on the fire suppression capabilities
of each community. The new PPC classes will improve the predictive value for insurers while
benefiting both commercial and residential property owners. Here are the new classifications
and what they mean.
Split classifications
When we develop a split classification for a community — for example 5/9 — the first number
is the class that applies to properties within 5 road miles of the responding fire station and
1,000 feet of a creditable water supply, such as a fire hydrant, suction point, or dry hydrant.
The second number is the class that applies to properties within 5 road miles of a fire station
but beyond 1,000 feet of a creditable water supply. We have revised the classification to
reflect more precisely the risk of loss in a community, replacing Class 9 and 8B in the second
part of a split classification with revised designations.
What’s changed with the new classifications?
We’ve published the new classifications as “X” and “Y” — formerly the "9" and "8B" portion of
the split classification, respectively. For example:
A community currently displayed as a split 6/9 classification will now be a split 6/6X
classification; with the "6X" denoting what was formerly classified as "9".
Similarly, a community currently graded as a split 6/8B classification will now be a split
6/6Y classification, the "6Y" denoting what was formerly classified as "8B".
Communities graded with single “9” or “8B” classifications will remain intact.
