ISO Rating & Response Statistics

  1. 1


Insurance Services Office (ISO) Rating

Through the Public Protection Classification (PPC™) program, Insurance Services Office (ISO) evaluates the performance of municipal fire suppression capabilities. The City rating schedule consists of three main areas: receiving and handling of fire alarms, the Fire Department, and water distribution and supply. Many communities use the PPC™ as a benchmark for measuring the effectiveness of their fire-protection services. The PPC™ program is also a tool that helps communities plan for, budget, and justify improvements. Additionally, insurance companies use PPC™ information to help establish fair premiums for fire insurance — generally offering lower premiums in communities with better protection.

In July of 2014, the City of Patterson received a Class 02/2Y Public Protection Classification from ISO. Class 1 generally represents superior property fire protection, and Class 10 indicates that the area's fire-suppression program doesn't meet ISO's minimum criteria. For additional information on the Public Protection Classification (PPC™) program, please visit the Insurance Services Office (ISO) webpage.
