The Mosier Fire District’s public protection classification by the Insurance Services Office has improved.  Many insurance companies use the ISO’s classification ratings as part of the basis for setting premiums, and an improvement in the public protection classification often means lower premiums for property owners.  Improvement in training and equipment for the Mosier Fire Department account for most of the new classifications.  The classification upgrades are in both the City of Mosier and the rest of the fire district.  Mosier Fire Chief Jim Appleton said he is cautiously optimistic the protection classification can see further improvement.
