Plano Fire Department has achieved an improved Insurance Services Office (ISO) rating of a Class 5. Plano was previously a Class 6 (the lower the ranking the better). The ratings reflect the effectiveness of a fire department in a given area when determining home insurance premiums. The ISO rating takes many factors into account. Some of the factors are quality of equipment, response time, water supply, dispatch/radio communications, and training of responding personnel. This new rating is effective April 1, 2016. Thanks to all the firefighters who helped make this possible.
