A land swap between the city of McMinnville, Warren County Schools and Warren County government has taken a short detour prior to full Warren County Commission consideration.“I need to hire an appraiser,” said County Executive Herschel Wells. “I need to get an appraisal on this property.”The request to allow that was made before a joint meeting of the county Budget and Finance Committee and Building and Grounds Committee. The land needing appraisal and under consideration for exchange is around West Elementary School and McMinnville Civic Center.
