According to DeKalb Fire Chief Donny Green, an increase in the counties Insurance Services Office (ISO) rating will mean lower insurance premiums for many residents. The new rating went into effect on Sept. 1, and the county’s Property Protection Classification (PPC) rating increased to 6 for all homes or properties located within five miles of a fire station, even if the homes are not near a fire hydrant or alternative source of water. The new rating will not affect Smithville and Alexandria residents, who have their own city fire departments.
