McMinnville fire protection remains among the best in Tennessee. In May 2008, the city’s fire department received a big boost on its insurance service (ISO) rating when it improved two points, going from 5 to 3. Its status was reaffirmed this month when another review resulted in an ISO rating of 3.“We have maintained our ISO rating of 3,” said McMinnville Fire Chief Kendell Mayfield during Tuesday night’s Board of Mayor and Aldermen meeting.
