On the evening of Tuesday August 4, 2015, Auditor Lawrence Hartlaub hosted a CAUV seminar to update agricultural owners on the new State of Ohio farmland value increases. The County Auditor hopes this allows the farming community advanced planning for the increases they will see on their tax bills in January 2016. The Power Point presentation has been uploaded for anyone that was unable to attend the meeting, along with a Frequently Asked Questions sheet.
